Rubber is a flexible and durable material that can be used in various temperature ranges and applications. Below, you can find detailed information about the properties and uses of different types of rubber.
1. Nitrile Rubber (NBR)
Nitrile rubber can be used within a temperature range of -40 °C to 105 °C, and it can withstand up to 120 °C in intermittent operations. It is preferred as a general-purpose material due to its resistance to oils and greases. Nitrile rubber has different formulations for fuels and industrial fluids, and cork-filled nitrile compounds are used in gasket production.
2. Polyacrylic Rubber (ACM)
Polyacrylic rubber is more resistant than nitrile rubber at high temperatures and in EP-additized oils; it can be used up to 150 °C. It has good ozone resistance but poor fuel resistance and limited low-temperature performance (minimum -30 °C). It is commonly used in gearbox seals.
3. Silicone Rubber (MQ, VMQ, PVMQ)
Silicone rubber can be used within a temperature range of -60 °C to 200 °C and can withstand up to 250 °C in intermittent use. Its primary application area is crankshaft seals. Silicone rubber offers high flexibility, air resistance, and excellent ozone resistance, but it is not recommended for use with fuels or EP-additized oils.
4. Fluorocarbon Rubber (FKM)
Fluorocarbon rubber can be used between -40 °C and 150 °C. It exhibits high resistance to phosphate ester fluids, glycol-based brake oils, water vapor, ozone, and weather conditions. However, it is not recommended for use with fuels and petroleum-based oils.
5. Styrene-Butadiene Rubber (SBR)
Styrene-butadiene rubber is used between -50 °C and 100 °C. It is resistant to glycol-based brake oils, acids and bases, and alcohol. However, SBR is not resistant to fuels and petroleum-based oils.
6. Natural Rubber (NR)
Natural rubber can be used within a temperature range of -60 °C to 90 °C. It has similar environmental resistance characteristics to SBR and is preferred in applications that require high flexibility and strong mechanical properties.
7. Hydrogenated Nitrile Rubber (HNBR)
Hydrogenated nitrile rubber is derived from NBR polymers. This material offers higher mechanical strength and improved resistance to wear. Its environmental resistance is similar to that of NBR, and its upper operating limit is 150 °C.
