- low leakage even with low viscous media
- high resistance to gap extrusion
- low cross-sectional deformation also under pressure
- easy to assemble
- no twisting in the groove

Injection molding machinery
Material NBR 85 black
NBR has good resistance to mineral oil-based oils and greases, aliphatic hydrocarbons, vegetable and animal oils and fats, hydraulic oils H, H-L, H-LP, hydraulic fluids HFA, HFB, HFC, silicone oils and silicone greases, water (max. 80°C).
NBR is not resistant to fuels with high aromatic content, aromatic hydrocarbons, chlorinated hydrocarbons, polar solvents, hydraulic fluid HFD, glycol-based brake fluids, ozone, weathering, ageing.
Application temperature range: -30°C to +100°C
Material FKM 80 green
FKM has good resistance to mineral oil-based oils and greases, synthetic oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, hydraulic fluids HFD, vegetable and animal oils and fats, silicone oils and silicone greases, fuels, non-polar solvents, ozone, weathering, ageing.
FKM is not resistant to glycol-based brake fluids, polar solvents (e.g., acetone), steam, hot water, amines, alkalis, low-molecular organic acids (e.g., acetic acid).
Application temperature range: -15 to +200°C
Material EPDM 80 violet, peroxide cured
EPDM has good resistance to hot water and hot steam, many polar solvents (e.g., alcohols, ketones, esters), many organic and inorganic acids and bases, alkaline washing solutions, silicone oils and silicone grease, ozone, weathering, ageing.
EPDM is not resistant to all kinds of mineral oil products (oils, greases, fuels)
Application temperature range: -45°C to +150°C
Also available in FFKM evolast®
for applications in particularly critical application conditions.
according to the different evolast® compounds:
either min. -40°C
