Our Materials for Rubber Extrusion

We master the extrusion of a wide range of technical elastomers, each selected for its unique properties against abrasion, chemical agents, extreme temperatures or specific environmental conditions. Regardless of the material chosen, we can transform it into solid or foam (sponge) profiles, perform co-extrusions, and offer custom finishes such as dimensional cutting or vulcanization in endless seals for perfect sealing.

FAQ - Rubber Extrusions

Custom rubber extrusion is a manufacturing process that transforms elastomer compounds into continuous profiles with specific cross-sections. We force the material through a custom die to create seals, tubes, gaskets, and technical profiles perfectly adapted to your equipment and specifications.

We extrude all major elastomer types: Neoprene (CR), SBR, HNBR, XNBR, Silicone, EPDM, Hypalon (CSM), Natural Rubber (NR), Butyl (IIR), Nitrile (NBR), Fluorosilicone, Polyurethane, and Viton (FKM).

We can extrude profiles from a few meters to several hundred meters in continuous lengths. Standard tolerances are ±0.5 mm on cross-sectional dimensions, with tighter tolerances available on request.

Yes. We can provide profiles certified FDA/NSF (food contact), RoHS, UL, USP Class VI (medical), ATEX (explosive atmospheres) and military specifications. Certifications are specified at the time of order.

Contact our specialists with your application details: equipment type, operating conditions (temperature, chemicals, pressure), required dimensions and material preferences. We'll analyze your needs and provide a technical recommendation and quote. Request a quote today!

Yes. We offer cutting (waterjet, saw, CNC), drilling, bonding, co-extrusion and other finishing services to deliver ready-to-install profiles.

Standard production takes 2 to 4 weeks, depending on tooling requirements. However, we understand that equipment failure cannot wait. We offer an emergency rush service for critical production stoppages, allowing us to prioritize your run and deliver parts in record time once the die is available.

For standard extrusion, the minimum is typically one production run (approx. 25-50 meters). However, for small profiles or lower quantities, we frequently utilize compression molding rather than continuous extrusion. This approach drastically reduces the minimum order requirement, offering a cost-effective solution for prototypes and short runs without the setup costs of a full extrusion line.
