Composite manufacture – FenForm

Available either cured or uncured, our unique FenForm™ is a high performance, reusable silicone membrane designed for composite manufacturing.

With high resistance to both tearing and creasing, FenForm™ provides the reliable, high quality solution required in vacuum moulding, laminating and ‘release cloth’ methods of composite production.


FenForm™ is reusable, providing a cost effective and environmentally-friendly alternative to disposable plastic bags in the VARTM (Vacuum Assisted Resin Transfer Moulding) and SCRIMP (Seemann Composites Resin Infusion Moulding) processes.

The silicone material is also flame resistant which provides an extra level of safety within your application. It provides excellent UV and ozone resistance, as well as strong chemical resistance, making it the ideal solution for your composite manufacturing needs.

Typical Material and Physical Properties:

  • Standard thickness of 1mm to 3mm (0.04” to 0.125”)
  • Standard widths of up to 1450mm (57”)
  • Cured material has fine fabric impression on both sides to aid removal
  • Standard colours of translucent or grey

Value adding features:

✔ Reusable – Less waste so more environmentally friendly, time and money saving over the life of the product

✔ Improved ergonomics

✔ Repairable

✔ No risk of creasing unlike nylon film

✔ Excellent UV and ozone resistance

✔ Good chemical resistance

✔ Highly durable over a wide temperature range (-40°C to 200°C)

✔ Good mechanical properties / high tear resistance

✔ High elongation with low modulus

✔ Good flame resistance

✔ Translucent sheeting means resin flow can be observed
