Rubber VMQ Silicone

The main characteristics of VMQ silicone rubber are that they retain good elasticity values even at extreme temperatures, particularly in pneumatic applications, where they are only slightly affected by ageing. However, they have little resistance to mechanical stress and prove easy to extrude under high pressures. Their purity and non-toxic characteristics make them particularly suitable for applications in the biomedical sector.
