Zilken sources elastomer semi-finished products and soft material components for industrial applications — drawing on its own experience and a well-established network of suppliers. These range from sheets, cut-to-size pieces, and profiles to custom-made molded parts and vibration dampers.
We work with the full range of technical elastomers—and expand it as needed through our supplier network: NBR, EPDM, FKM/FPM, VMQ/MVQ (silicone), SBR, natural rubber, CR, as well as FFKM, HNBR, and FEPM (Aflas®) for extreme media and temperature requirements. This is complemented by soft materials such as aramid fiber sealing material, fiber sealing materials (Klingerit-type), foam, sponge rubber, as well as glass and high-temperature fabrics and PTFE.
For pressure equipment and media-critical applications, we provide material certificates and test reports in accordance with EN 10204 (3.1). Compatibility certificates in accordance with ISO 1817 (liquids) and ISO 1431 (ozone) are available upon request, along with supplier certification. For applications involving food contact or drinking water, we comply with FDA, KTW, and DVGW standards — as well as WRAS, 3-A Sanitary, and ACS.
Elastomers are specified by hardness. We cover the entire range from 15° to 90° Shore A—with a focus on 60°, 65°, and 70° Shore A. Tolerances of ±5 Shore are standard; all hardness levels are available upon request.
We supply rubber sheets in thicknesses ranging from 0.9 to 50 mm, in standard sizes or cut to size according to drawings and custom dimensions. Profiles and cords are available as continuous lengths, by the meter, and in cut lengths. Custom cuts based on CAD contours are available upon request.

Through our supplier network, we also source, upon request, high-performance elastomers such as FFKM, HNBR, and FEPM (Aflas®) for extreme resistance to media and temperatures, custom cuts based on CAD contours, and products with special certifications for food and drinking water applications in accordance with WRAS, 3-A Sanitary, or ACS. The same applies to flame-retardant, antistatic, or electrically conductive versions, as well as high-temperature materials for applications above 200 °C. If your requirement is not listed on this page, please contact us.
Customers who purchase elastomer semi-finished products based on a bill of materials can also receive them as pre-assembled sets. We put together pre-picked, labeled, and ready-to-install kits and component sets. This reduces the effort required for sorting during production, keeps inventory levels low, and demonstrates how pre-assembly and sets effectively combine procurement and assembly.
Elastomers, seals, molded parts, and C-parts can be purchased in a single order from a single point of contact with a single delivery. As a system partner, we handle supplier selection, certificate management, and incoming goods inspection.
Yes. We supply rubber sheets and panels in thicknesses ranging from 0.9 to 50 mm as custom-cut pieces based on drawings or specific dimensions. For custom shapes based on CAD files, we source the material through our supplier network upon request.
Our standard product line includes NBR, EPDM, FKM/FPM (Viton®), VMQ/MVQ (silicone), SBR, natural rubber, CR (Neoprene®), and FFKM. In addition, HNBR, IIR (butyl), AEM (Vamac®), and FEPM (Aflas®) are available through our network.
Part of our product line is available with FDA approval for food contact or KTW certification for drinking water applications. For applications subject to DVGW requirements, please coordinate your needs directly with us. Additional certifications (WRAS, 3-A Sanitary, ACS) can be provided through our network.
By default, dimensional tolerances comply with DIN 7715 and ISO 3302. Hardness testing is performed in accordance with DIN 53505 or ISO 7619. Fluid resistance testing in accordance with ISO 1817 and ozone resistance testing in accordance with ISO 1431 are available upon request with supplier certification.
Yes, upon request. We provide 3.1 factory certificates in accordance with EN 10204, provided they are available from the manufacturer. Please specify this in your request.
Elastomer Components include semi-finished products, sheets, blanks, profiles, buffers, and molded parts made from elastomer and soft materials. Traditionally manufactured sealing elements such as O-rings, shaft seals, and flat gaskets as finished parts are the focus of this product group Sealing Technology.
Sealing Technology Maximum Plant Availability: O-rings, flat gaskets, and mechanical seals prevent leaks—whether standardized or custom-made to your specifications.
Custom & Machined Parts precision components: plastic, metal, and rubber parts produced via injection molding, casting, or 3D printing—from prototypes to complete production assemblies.
Fasteners every application: screws, nuts, rivets, and bolts—DIN-compliant parts and custom-made products, from small quantities to large-scale production runs.
