DYNA-PURGE M is a versatile non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to flow naturally through the barrel and hot runner system of the injection molding machine, as well as extrusion equipment. Two non-melting but softening thermoplastic ingredients scrub,...

DYNA-PURGE K is a low-temp, non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to flow naturally through the barrel and hot runner system of the injection molding machine, as well as extrusion equipment. A non-melting but softening thermoplastic scrubs the screw and...

DYNA-PURGE P is a non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to have a natural flow through the barrel and hot runner system of the injection molding machine. An advanced formulation, with dual action scrubbing, expands into tight channels and negative flow...

DYNA-PURGE F is a non-abrasive, non-chemical engineered thermoplastic purging compound with a proprietary additive, formulated to flow naturally through the barrel and hot runner system of the injection molding machine.

DYNA-PURGE E is a high heat-resistant, non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to purge high-temperature engineering resins. A non-melting but softening thermoplastic scrubs the screw and barrel of both injection molding machines and extruders, while the...

DYNA-PURGE V is a non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to flow naturally through the barrel of the injection molding machine and extruder. A non-melting but softening thermoplastic scrubs the screw and barrel, while the carrier matrix flushes away...

DYNA-PURGE C is a clear, non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to purge high clarity resins such as PET, GPPS, PC, SAN and PMMA. A proprietary additive expands allowing for the purge to reach and clean all areas of the machine. The carrier matrix then...

DYNA-PURGE SF is a non-abrasive, non-chemical engineered thermoplastic purging compound with a proprietary additive, which allows the purge to expand and scrub the screw and barrel, die, and other downstream equipment. The material is designed for extruders and co-extruders that have limited...

DYNA-PURGE X is a non-abrasive, non-chemical engineered thermoplastic purging compound, designed to have a natural flow through the extruder. An advanced formulation with dual action scrubbing expands into negative flow areas, loosening and removing degraded material. This grade is designed for...

DYNA-PURGE B is a non-abrasive, non-chemical engineered thermoplastic purging compound, formulated to flow naturally through the barrel and accumulator head. A non-melting but softening thermoplastic scrubs the screw and barrel, while the carrier matrix flushes away impurities.
