PlatSil® HTS-25 Fast Silicone Rubber


PlatSil® HTS-25 Fast Silicone Rubber is a high-performance, platinum-catalyzed silicone with excellent tear strength, tensile strength and elongation properties. This silicone features a fast demold time of ~3 hours for quick turnaround.

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 (this option has a longer working time - 70 min. - and longer demold time - 24 hr. - compared to HTS-25 Fast) and PlatSil® HTS-40 (Shore A40).
