Silicone (MQ, VMQ, PVMQ) Material Description
VMQ (silicone) is very frequently used in industry.
This is partly because silicone is comparatively inexpensive and
partly because silicone has attractive
properties for most branches of industry.
For example, silicone has high elasticity, outstanding flexibility
at low temperatures down to -60°C,
excellent weather resistance and basic compliance with FDA
guidelines.
Accordingly, silicone is used in particular in the food industry,
the pharmaceutical industry and in plant
engineering.
