TTK-3700E is a polyethylene-based processing aid for extrusion applications. It is an organically modified polysiloxane masterbatch. By combining the initial lubricating effect of polysiloxane with the polar interaction of modified functional groups, the product migrates to the processing equipment surface during extrusion and takes effect there. As a result, even a small addition effectively improves resin flowability and processability, reduces die build-up, and improves sharkskin defects.
