How to improve the toughness of Silicone sponge rubber？

With the improvement of technology, product upgrading and the emergence of silicone sponge rubber, it has set off a boom in the industry. Silicone sponge rubber, also called additioned silicone, is a two-component heated vulcanized silicone rubber.

It has excellent electrical properties and chemical stability, is resistant to water and weathering, is non-toxic and odorless, has low linear shrinkage and is easy to operate.

In terms of application, silicone sponge rubber can be used to make flexible silicone rubber products such as human bodies, insoles, shoulder pads, patches, and anti-slip mats. It can also be used to make silicone foam sealing strips, silicone foam sheets, earthquake-resistant silicone foam boards, silicone foam rolls, etc., and plays the role of shock-absorbing and cushioning accessories.

Recently, one of Hito's customer who is manufacturer of silicone sponge rubber consulted to us how to improve the toughness of his products？

The answer is as belowing: in order to improve the toughness (tear strength) of additioned silicone sponge/foam rubber, Hito's hydrogenated silicone resin or vinyl silicone resin can be added.

Thanks for your attention~
