Si-TPV® 3320-60A Thermoplastic Elastomer
describe:
Si-TPV® is a patented silicone thermoplastic elastomer developed by Chengdu Silico Technology Co., Ltd. This special material is made of fully vulcanized silicone rubber with a thickness of 1-3um through special compatibility technology and dynamic vulcanization technology. It forms a special island structure, thus solving the problem of incompatibility between TPU and silicone. Its performance is much better than ordinary thermoplastic vulcanized rubber TPV, and it is called super grade TPV. Si-TPV® combines the low hardness, high and low temperature resistance, and chemical resistance of silicone rubber high resilience and TPU’s outstanding mechanical strength, good biocompatibility and a series of advantageous properties. It has high compatibility and good coating properties. It can be co-extruded or two-color injection molded with many thermoplastic engineering plastics such as PC, ABS, PVC, etc. formingTwo-color injection molding. Si-TPV®3320-60A shows excellent skin-friendly touch and stain resistance, no precipitation, and no stickiness after aging in watch straps, bracelets and other fields.

Description
SILIKE Si-TPV® thermoplastic elastomer is a patented dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in TPU evenly as a 2~3 micron particles under microscope. Those unique materials combine the strength, toughness and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone: softness, silky feel, UV light and chemicals resistance which can be recycled and reused in traditional manufacturing processes.
Si-TPV® 3100-60A thermoplastic elastomer is a material with good abrasion and chemical resistance which special developed for soft touch extrusion molding grade, It can be co-extruded with many thermoplastic engineering plastics such as PC, ABS, PVC, etc. no precipitation, no sticking after aging and other characteristics …
