Clean VHT

This grade pushes back the limits of Clean Xpress purging compounds by reaching 320°C as maximum temperature while ensuring the most efficient cleaning efficiency in the market (recognized by industry peers and third parties).

Clean LDPE

CLEAN LDPE significantly reduces the cleaning time of the screw of the extruder. He runs smoothly and can itself be easily removed from the extruder.
