Your development partner with leading materials expertise
The seals and gaskets Daetwyler Rubber makes for building construction have to withstand wind, weather and temperature changes. Choosing the right rubber compound is critical to the permanent elasticity, non-ageing properties and weather resistance for which our sealing products are known.
Application-specific materials for building construction
Our in-house rubber compound design and manufacturing capabilities have earned us recognition as a development partner able to deliver innovative solutions and the most consistent quality. We are known for our years of experience in developing materials tailored to specific applications:
List
- Elastomeric materials based on EPDM and silicone rubbers according to international standards (DIN 7863, NFF 85 301, EN 12365)
- Coloured compounds for co-extrusion to provide a coloured visible or paintable surface
- Conductive silicone materials for active security or gate controls
- Self-lubricating elastomeric materials for reducing frictional forces
- Foam rubber materials for reducing thermal conductivity
- Elastomeric materials with magnetic properties for use as an assembly aid or sensor
Development of flame retardants
Fire safety requirements for seals and gaskets are especially important in building construction. This is another area where Daetwyler Rubber is at the leading edge of development:
List
- Materials based on chloroprene for high flame retardancy according to DIN 4102 B1 and B2
- 60 Shore A, 70 Shore A and 80 Shore A
- EPDM-based materials for use in rail vehicles according to international fire safety requirements, e.g. DIN 5510 and NFF 16101
- Silicone materials for use according to BS 6853, NFF 16101 and DIN 5510
