Guide to rubber properties
This information is for guidance only and given in good faith but no warranty given or implied. Samples available for testing.
Natural
Natural rubber offers a good balance of properties, particularly for mechanical applications and can be compounded to produce high resilience, good tensile strength, low compression set and high tear properties over a wide range of hardness. The abrasion of natural rubber is good. It has better resilience and maintains flexibility at lower temperatures better than most synthetics. However natural rubber is less resistance to ozone, petroleum oils and fluids than some synthetics.
Styrene Butadiene
SBR rubber has similar properties to natural rubber but with improved resistance to abrasion and ageing. It is widely used in tyre treads, seals, gaskets and footwear. It has good impact strength and performs well in low temperatures. However, it has poor resistance to ozone, sunlight, and oil-based fluids. It is cost-effective and blends easily with other rubbers. Its overall performance makes it one of the most commonly used synthetic rubbers for general-purpose applications in both industrial and automotive sectors.
Neoprene
Chloroprene, generally known as Neoprene, has more resistance than natural rubber to sunlight, ozone and oxidation. It has good resistance to heat and does not soften as much as natural rubber under severe exposure. It has moderate oil resistance but it is not suitable for use with petrol. Neoprene can be compounded to offer flame retardant properties. Its weather and ageing resistance makes it useful for outdoor and marine environments, as well as cable jackets, seals, and vibration mounts in various industrial uses.
NBR
Acrylonitrile, generally known as Nitrile, has excellent resistance to oils, fuels, water and petroleum-based fluids. It is widely used in automotive and industrial applications such as fuel hoses, gaskets, O-rings and seals. Nitrile offers superior resistance to compression set, cold flow and abrasion compared to most elastomers. It performs well across a wide temperature range but lacks resistance to ozone, sunlight and weathering. It can be blended with other rubbers to improve flexibility while retaining its key resistance properties.
Silicone
Excellent resistance to extremes of temperature. Temperatures as high as 200oc have little effect on the physical properties of this elastomer. However, it has poor tensile strength, tear, abrasion and steam resistance. It has very good resistance to sunlight, ozone, gases and possesses good electrical insulation properties, water repellency and non adhesives.
Ethylene Propylene Rubber
Ethylene Propylene rubber has excellent resistance to ageing, weathering, ozone, oxygen, and many chemicals. Temperatures as low as -50°C have little effect on the physical properties of this elastomer. However, it is unsuitable for petroleum-based liquids. It has very good resistance to steam, water, and glycol-ether hydraulic fluids and provides reliable electrical insulation properties and weather stability.
Polyurethane
Polyurethane elastomers offer outstanding abrasion resistance and very high tensile strength, tear strength, and load-bearing capabilities at moderate temperatures. They demonstrate excellent resistance to oils, greases, certain solvents, ozone, sunlight, and weathering. However, their resistance to acids and alkalis is limited.
Viton®
Viton® has very good resistance to most chemicals and commercial fluids. It maintains strength and flexibility at elevated temperatures and effectively resists embrittlement during prolonged heat exposure. Additionally, it provides reliable performance against oils, fuels, and many aggressive chemicals, making it suitable for demanding high-temperature applications.
