PFAS-free PPA

100% Pure PFAS free PPA / fluorine free PPA product

SILIMER series products are PFAS-free polymer processing aids (PPA) which were researched and developed by Chengdu Silike. This series of products is Pure modified Copolysiloxane, with properties of polysiloxane and the polar effect of the modified group, the products will migrate to the equipment surface, and work as a polymer processing aid(PPA). It is recommended to be diluted into a certain content masterbatch first, then used in polyolefin polymers, with a small addition, the melting flow, processability, and lubricity of the resin can effectively improved as well as eliminate meltfracture, greater wear resistance, smaller friction coefficient, extend equipment cleaning cycle, shorten downtime, and higher output and a better products surface, a perfect choice to replace pure fluorine-based PPA.

PFAS FREE / fluorine free PPA masterbatches

SILIMER series PPA masterbatch is a new type of processing aid containing modified copolysiloxane functional groups with different carriers like PE, PP..eg. It can migrate to the processing equipment and have an effect during processing by taking advantage of the excellent initial lubrication effect of polysiloxane and the polarity effect of modified groups. A small addition of it can effectively improve the fluidity and processability, reduce the die drool, and improve the phenomenon of shark skin, it has been widely used to improve the lubrication and surface characteristics of plastic extrusion. Typical applications like plastic film, pipe, masterbatches, artificial grass, resins, sheets, wire&cables...eg.
