For most molders and extruders, changing from one material to another or from one color to another is a mandatory task that often consumes more time and material than is good for the business.   To make this process both more efficient and more cost-effective HiTech Polymers has developed a unique family of  easy-to-use purge polymers that perform much better than the commonly used practice of simply purging barrels and screws with polyethylene.  

Purge polymer products consist of a family of specialty thermoplastic polymer purging compounds specifically and uniquely engineered to clean thermoplastic resins from plastic processing equipment.  The materials are designed to effectively and efficiently remove colored, degraded, or contaminated polymer from molding or extrusion systems within a short period of time. Purge Polymers lessen downtime, enables quick changeovers and reduces off-specification parts. Custom formulations and FDA grades are available.
