High Strength Silicone

Designed to have a significantly higher elongation and tear strength than general purpose silicone.

It can be used for moulding, extrusion and calendering and the final products are generally more resistant to abrasion and fatigue than general purpose silicones. High strength silicones are also widely used for straps and medical tourniquets.

An additional process available at Primasil is automated silicone punching. This enables very cost efficient production for high volume runs. Of course, as we mix ALL of our high consistency silicone on site we always achieve the best prices possible for these high strength silicone products.
