产品说明:
热塑性弹性体（TPE）系列中一种柔软、可着色的特种热塑性硫化胶（TPV）。它符合食品及药物管理局（FDA）对重复使用的橡胶制品以及与非脂肪、非油性食品接触的橡胶制品的规定，如封口和密封垫圈。这种等级的Santoprene TPV是剪切依赖的，可以在常规热塑性塑料设备上进行注塑或挤出加工。它是聚烯烃为基础，完全可回收。
A soft, colorable, specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It complies with FDA regulations for rubber articles intended for repeated use, as well as those in contact with non-fatty, non-oily foods as closures and sealing gaskets. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding or extrusion. It is polyolefin based and completely recyclable.
