The compound decides how long a part survives in your assembly. Here are the working ranges and resistance of every group — so an engineer can choose the material without calling.
Mark what the part meets and how hot it gets — we will show the compound groups that fit.
The workhorse for oil and fuel
Water, steam and outdoor exposure
General purpose, economical
Maximum resilience and wear
Wide temperature range, food-grade options
Aggressive media and high temperature
Where everything else wears out
The selector is indicative: ranges are for continuous service, agree short-term peaks with our technologist. The final compound for your pressure, motion and service life is set by our technologist.
| Grade | Temperature | Hardness, Shore A | Resistant to | Not suitable for |
|---|---|---|---|---|
| NBRNitrile rubber | −30 … +100 °C | 40–90 | Oil and petroleum products, Petrol, diesel, Abrasion and wear | Weather, ozone, UV, Acids |
| EPDMEPDM rubber | −50 … +150 °C | 40–90 | Water, Steam and hot water, Acids, Alkalis, Weather, ozone, UV | Oil and petroleum products, Petrol, diesel |
| SBRSBR rubber | −45 … +100 °C | 40–90 | Water, Abrasion and wear | Oil and petroleum products, Petrol, diesel, Weather, ozone, UV |
| NRNatural rubber | −55 … +80 °C | 30–90 | Abrasion and wear, Water | Oil and petroleum products, Petrol, diesel, Weather, ozone, UV |
| VMQSilicone rubber | −60 … +250 °C | 30–80 | Weather, ozone, UV, Water, Food contact | Steam and hot water, Abrasion and wear, Petrol, diesel |
| FKMFluoroelastomer | −20 … +250 °C | 60–90 | Oil and petroleum products, Petrol, diesel, Acids, Alkalis, Weather, ozone, UV | Steam and hot water |
| PUPolyurethane | −30 … +80 °C | 60–95 | Abrasion and wear, Oil and petroleum products | Steam and hot water, Acids, Alkalis |
Ranges are for continuous service. Exact figures depend on the specific compound and are confirmed per order by our technologist.

Four questions whose answers let us get the compound right the first time.
What the part touches: oil, fuel, water, steam, acid, alkali. A mistake here cuts service life several times over.
The working range and short-term peaks. The upper limit narrows the choice far more than the lower one.
Static sealing, impact loading or constant abrasion — this drives both hardness and compound filling.
A fixed joint, reciprocating movement or rotation — this shapes both the compound and the geometry of the part.
