These include the type of resin, the environmental conditions, the degree of crystallinity, and the presence of fillers or additives.<\/p><p>For example, hygroscopic resins have a higher affinity for water molecules and tend to absorb moisture more readily than non-hygroscopic resins. Environmental conditions such as temperature and relative humidity can also influence moisture absorption rates. Higher temperatures and higher relative humidity levels generally result in faster moisture absorption. The degree of crystallinity of the resin can also affect its moisture adsorption rate and capacity. Resins with higher degrees of crystallinity tend to have lower moisture adsorption rates and capacities. Finally, the presence of fillers or additives in the resin can also affect its moisture adsorption rate and capacity. Certain fillers or additives can act as moisture barriers and reduce the resin&#8217;s ability to absorb moisture.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f9951c7 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"f9951c7\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6d565e0 elementor-widget elementor-widget-text-editor\" data-id=\"6d565e0\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>What is the best dryer for PET regrind drying for running preforms?<\/h2><div><p>If you&#8217;re looking for the best type of dryer to use for PET regrind drying when running preforms, it depends on a few factors. First, you&#8217;ll want to consider the source of the regrind and how it&#8217;s being combined before it goes into the Injection Machine.<\/p><p>Luckily, dryers have come a long way in terms of energy efficiency and user-friendliness. Both dual bed and wheel dryers can work well, but wheel dryers tend to have a more consistent dew point and temperature, which is especially important for preform manufacturing. (The machines, often Husky brand, require a consistent temperature to the machine throat for the best preform production.)<\/p><p>One option you might consider is\u00a0Novatec&#8217;s IntelliPET dryer, which is specifically designed for preform production and consistency. It also features variable frequency drives that adjust power based on the material rate, resulting in lower energy usage compared to older models.<\/p><p>If the regrind is preform regrind, you can generally add it in up to 10-15% without much hardware change. If the regrind is re-pelletized, you can use it much like virgin resin, although it may have a slightly lower IV than virgin resin.<\/p><p>However, if the regrind is PCR (post-consumer) flake, there are some additional factors to consider. PCR has already been through a heat cycle and has a lower IV, as well as a tendency to produce volatile compounds that can contaminate the desiccant materials during the drying process. To prevent this, you may need to add an additional treatment step to the hopper&#8217;s return air to limit and desiccant contamination.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-91f95ef elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"91f95ef\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-16b282e elementor-widget elementor-widget-text-editor\" data-id=\"16b282e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>What are some potential issues that could cause hard shell luggage cases (70% resin, 30% regrind) to break during drop tests?<\/h2><div><p>One of our experienced PC processors suggested a few potential issues that may be causing the shells to break after drops:<\/p><\/div><div><ol><li>The resin may not be properly dried, and since the PC is colored, you may not see the air bubbles, and thermoforming usually doesn\u2019t show the kind of surface splay you would see with injection molding.

In colder and dryer times of the year, when the air outside is dry, the material is already fairly dry. But, when the weather is humid, the material is more humid and your dryer must work harder to remove its accumulated moisture. An older, or outmoded dryer will have a more difficult time providing uniform drying results. Check how old your desiccant is and replace it if it is more than 2 years old. Make sure all heaters are operating at full capacity and, of course, the blowers of your dryer must be operating correctly. Make sure the process and regeneration filters are clean because dirty filters can reduce the airflow, which has a direct effect on the efficiency of the dryer.<\/p><p><em>Jeff Rodway, Service Manager, Novatec Inc.<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d5a8af3 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"d5a8af3\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c0fb3a9 elementor-widget elementor-widget-text-editor\" data-id=\"c0fb3a9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>How negative must we be on the hoppers to pull air through the hopper back to the dryer?

If so, I recommend that the primary restriction occurs at the hopper outlet rather than the inlet.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ff8e02 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"3ff8e02\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d67cdea elementor-widget elementor-widget-text-editor\" data-id=\"d67cdea\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>Currently using PVC durometer 65 bubbles in the injected outsole.<\/h2><p>Although PVC is typically not hydroscopic, the presence of moisture on the surface can lead to inconsistent processing and the requirement for adjustments in the Injection Molding Machine.<br \/>The use of a Hot Air Dryer will remove the surface moisture and keep the PVC at a consistent temperature such that machine process parameters do not require as much monitoring and result in a more consistent product.<br \/>There are also IMM parameters that can lead to bubbles in the PVC.

Temperatures in excess of this lower the desiccant capacity and require that the air be cooled before going to the desiccant. This cooling of the air, for better adsorption, means that you have heated the air unnecessarily and thrown that heat into cooling water which requires more process heat to be re-added.<br \/>Novatec\u2019s Power Guard systems continuously monitor the return air temperature and adjust the process airflow for optimum drying and minimum energy usage through a patented process that also adjusts the set point based on resin temperature.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f4f1113 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"f4f1113\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-07f3ffc elementor-widget elementor-widget-text-editor\" data-id=\"07f3ffc\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>I have heard that Cactus dryers do not work well unless there is only surface moisture because they use ambient air passed over heaters. Is this correct?<\/h2><p>The Cactus is typical of hot air dryers with the exception that it uses compressed air instead of blower power to move the air. Because of this, it will be slightly lower in dew point, at times, if your compressed air is very dry. However, it will not be more consistent than your plant relative humidity. This can be an issue, especially in the summer.<\/p><p>When drying PU, it is usually important to control both the temperature and resin moisture to get consistent product flexibility and strength.<\/p><p>There are other dryers that use compressed air and a membrane and develop very consistent processing of PU. The\u00a0<a href=\"https:\/\/www.novatec.com\/product-category\/dry\/membrane-compressed-air-and-nitrogen\">NovaDrier<\/a>\u00a0is a good example of these and it uses far less power and compressed air than any other of its kind.

I\u2019m following the instruction manual, and everything seems to be working correctly. I\u2019m using a compressed air dryer and I was told that it would dry most materials under most conditions.<\/h2><p>We\u2019ve heard this story before. Unfortunately, you never know when the problem will crop up.\u00a0<a href=\"https:\/\/knowledge-center.novatec.com\/resin-moisture-drying\/resin-dryer-technologies\/compressed-air-dryers\/\">Compressed air dryers<\/a>\u00a0only produce a dew point of about -10 degrees, under the best of circumstances, but summer temperatures or high humidity can push the dew point up to +10 or +20 degrees. That\u2019s when you notice defects in your molded products.<\/p><p>There are also other problems with regular compressed air dryers but let\u2019s concentrate on your current problem.<\/p><p>First, I think you should call the manufacturer of your dryer and see if there is any way to return it, depending on how old it is and what your warranty says. If that is not possible, ask if they have a membrane option. If you buy the membrane option and install it, you will get -40\u02dadew point process air and that should solve the current problem.<\/p><p>Note that regular compressed air dryers consume a lot of compressed air and when you add an optional membrane, the compressed air usage goes even higher. Next time you buy a dryer, consider one with a built-in membrane to save lots of energy and be guaranteed that you can dry all resins, regardless of the time of year.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b0d1607 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"b0d1607\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2f37330 elementor-widget elementor-widget-text-editor\" data-id=\"2f37330\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>How do I know whether resin dryer desiccant beads are still good?<\/h2><ul><li>Visual inspection &#8211; Color should be creamy, eggshell white in color.
