Silicone Membrane 40 Shore A – 2 mm Thickness, 2000 mm Width, 700% Elongation

The 40 Shore A silicone membrane with a 2 mm thickness is a high-performance, highly elastic material designed for vacuum pressing, laminating, thermoforming, and composite processing. Its excellent flexibility and durability ensure long-term, stable operation even under intensive industrial workloads.

High heat resistance and elasticity

Manufactured from industrial-grade silicone compound ASU-4079, the membrane features a hardness of 40 Shore A and combines outstanding elasticity of up to 700% with a continuous working temperature of up to 200 °C. The 2 mm thickness provides precise forming of complex shapes, uniform pressure distribution, and a clean surface finish without marks. The semi-transparent milky-beige tint helps monitor workpiece positioning during pressing — especially useful when working with shaped or contoured parts.

Used in the following fields:

  • forming of artificial stone and composite materials;
  • thermoforming of acrylic and plastics;

Advantages of silicone membranes

  • stable performance at temperatures up to 200 °C;
  • compatible with most European vacuum press models.

How to choose the membrane length?

The length must fully cover the working area of the press with a 5–10 cm margin. If you are unsure, contact us and we will recommend the correct size.

Are the membranes compatible with presses from other manufacturers?

Yes, the membranes are compatible with equipment from most European brands. Provide the press model, and we will help you choose the right length.

What is the service life of a silicone membrane?

On average, 6–12 months of regular use. The lifespan depends on temperature, materials, cleanliness of the workpieces, and the number of operating cycles.

Can a silicone membrane be used in woodworking?

Yes, silicone membranes can be used in:

  • veneering;
  • laminating and surface cladding;
  • 2D forming of complex-shaped parts;
  • production of furniture fronts, interior panels, advertising elements.

However, material specifics must be considered: silicone membranes have lower resistance to mechanical damage compared to natural rubber membranes. Therefore, for woodworking tasks involving frequent contact with sharp edges, we recommend using a natural rubber membrane, which better withstands point loads.
