Silicone Rubber Solutions for vacuum forming and vacuum membranes

Demand on the energy sector is higher than ever. This has led to an increasing need for efficiency improvements to be made using reliable products, whilst limiting impacts to the environment.

This is where the expertise of engineering technical specialists, Silicone Engineering, comes into play. Silicone rubber is widely used within the energy sector due to the material’s high-performing properties, such as the precision-engineered vacuum membrane sheets that provide a highly durable and robust solution within the solar energy industry.

Silicone rubber, with its host of features and benefits, delivers superb solutions for the manufacture of wind and solar energy parts. A wide temperature range and resilience, combined with its thermal and chemical stability, makes silicone rubber the perfect solution for vacuum membranes used in the vacuum forming process to produce composite components such as wind turbine blades and solar panels.

Product features

Why choose kSil®VAC silicone rubber for vacuum forming?

As expert engineering technical specialists, we have formulated and developed kSil™VAC membrane sheets, which boast features and benefits, including:

Temperature resistance

Silicone rubber boasts extreme temperature resistance and chemical stability, making it the ideal substance from which to produce high-performing vacuum membranes. With silicone’s extreme temperature range (-60°C to +230°C), the material will not degrade with fluctuations in temperature unlike more conventional rubbers.


Silicone is highly durable and boasts high tear strength, elongation and a long lifespan. These features make it a perfect material for vacuum membrane sheets for the manufacturing of solar panels. Providing high elasticity under vacuum, vacuum membrane sheets need to withstand pressure to bond solar cells together.


Silicone has outstanding weathering properties, which offer superb protection for wind-generated energy turbines. Wind turbines are consistently exposed to extreme environmental conditions and rely on a highly protective and robust material.
