The low usage rate, low minimum order quantities, and pelletized form for easy handling and storage make it a versatile and cost-effective choice.

A material is shear dependent when its viscosity is higher at low shear rates (such as extrusion) and lower at high shear rates (as in injection molding). Therefore, SBC TPEs will flow more easily into thin areas of the mold at high shear rates. Increase injection rate.

Avient was able to identify a local supplier of dependable laser-marking equipment, and ran tests on the machinery so the customer could calculate its output rates and also judge the level of marking contrast.
