Go Green with XPD8®: Plastic Purge Compounds. We have a purge compound available for most plastic purging applications and heat ranges. Our Plastic Purging Material is available in Concentrate, Redi-Mix, and Liquid form. XPD8® Plastic Purging Compounds are technologically advanced to meet the future demands of a maturing plastics industry by deep cleaning plastic processing machines. XPD8® Plastic Purging Compounds have internal chemical reactions activated by the heat of your machine. These timed chemical reactions will degrade the residue or thermoplastic, significantly lowering the molecular weight of the contamination. This process is achieved by safely breaking down the plastic at its molecular level, thereby lowering its viscosity making it easy to get out of your system. Our XPD8® purging agent removes loosened and degraded colorants, additives, and plastics stuck in your machines. When the chemical reaction is finished XPD8® degrades itself and is easily removed from your machines. Our entire line of plastic purging agents are FDA Compliant making them ideal for Food and Medical Packaging. XPD8® grades have no unnatural odor such as ammonia, and contain no fiberglass, chlorides, or any non-melting particles. For a quick changeover and increased profits, try XPD8® Plastic Purge Compound.
