Discover how we manufacture metal-reinforced silicone profiles.

We offer customised profiles in any colour and can also manufacture vulcanised frames.

Contact us for our high-quality sealing solutions.

We have incorporated another vertical silicone extrusion line.

This extrusion line offers qualitative benefits in production and

optimizes energy and quality for silicone vulcanization.

We specialize in the custom fabrication and supply of silicone extrusion profiles. This process can lead to a more complex co-extrusion, which involves the combination of 2 or more materials.

• Using two types of silicone, solid HTV and sponge HTV.
• With different silicone formulations, hardness, and color.
• Silicone combined with other materials, metallic or textile inserts, reinforcing the final product.

Custom-made inflatable silicone seals for autoclaves, dynamic seals for laboratories, metallic or silicone valves.

Our inflatable seals provide total sealing against gases, liquids and solids.
