PlatSil® HTS-25 Silicone Rubber

SKU:
HTS25U9

PlatSil® HTS-25 Silicone Rubber is a high-performance, platinum-catalyzed silicone with excellent tear strength, tensile strength and elongation properties.

Molds and parts made with this silicone stand up to the rigors of high-volume production environments and repetitive demolding or stretching; common applications include concrete casting, medical modeling and training aides, and prototyping.

This room temperature curing (RTV) silicone cures to a milky white, Shore A25 rubber. PlatSil® HTS-25 is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application.

Other silicones in the HTS-Series include and PlatSil® HTS 25 Fast (a faster-setting version of the HTS-25) and PlatSil® HTS-40 (Shore A40).
