Materials
Whatever type of material characteristics you need: we will find the best appropriate material compound for your application needs – functional reliably up to the limits.
The materials are divided through the following aspects: their composition, properties and resulting application range in elastomeric materials, PTFE-based materials, materials with and without elastic properties i.e. TPU.
Elastomers are chemical cross-linked, permanently elastic materials that feature a viscoelastic behavior. These come in a numerous of variants as sealing materials:
(NBR) acrylonitrile butadiene rubber
(HNBR) hydrogenated nitrile butadiene rubber
(EPDM) eythylene propylene diene rubber
(VMQ) vinyl methyl rubber (silicone)
(FVMQ) fluoro vinyl methyl rubber (fluorosilicon)
(SBR) styrene butadiene rubber
The specified hardness designation in the material compound data sheets will be given in Shore A. Whereas on finished parts, the hardness is usually determined in IRHD-m.
Thermoplastic elastomers are referred to as materials that can be processed like a thermoplast, but have elastomeric properties.
(TPU) thermoplastic polyurethane
(TPU72) thermoplastic polyurethane 72 Shore D
PTFE based materials
PTFE - Polytetrafluorethylene is a sintered material with very high chemical and thermal resistance, but without any elastomeric properties. Sealants made of PTFE are commonly machined out of extruded semi-finished products.
