Overview SBR Compounds

Material Description
SBR is similar to natural rubber in most respects and is the most cost-effective and highest-volume elastomer on the market. Although its physical properties are slightly worse than those of natural rubber, SBR is tougher and more resistant to heat and cracking and can easily be replaced by natural rubber in many applications. With the exception of silicone, butadiene has the lowest glass transition temperature of any commercially available elastomer and offers exceptionally good performance at temperatures as low as -62° C (-80° F).

Main Properties
Very good elasticity, tensile strength, abrasion resistance and flexibility at low temperatures.

Limits
Poor resistance to ozone and sunlight; very low resistance to oils, petrol and hydrocarbon solvents.

Overview AU Compounds

Material Description
Polyurethane is characterised by the combination of hardness with elasticity, excellent abrasion resistance and high tear resistance. It can be either ether or ester based. The ester-based polymer is superior in resistance to abrasion and heat; the ether-based polymer has better flexibility at low temperatures. Polyurethanes are available in both liquid and solid form. Polyurethanes are mainly used in applications that require a combination of their excellent properties: Toughness, tensile strength and abrasion resistance.

Main Properties
Excellent abrasion and tear resistance; very high tensile strength with good elongation; excellent weather, ozone and sun resistance; good oil and petrol resistance; excellent adhesion to textiles and metals.

Limits
Poor resistance to alkalis, acids and oxygenated solvents; poorer resistance to hot water.

Overview ACM Compounds

Material Description
The heat resistance of acrylic is better than that of most elastomers, with the exception of silicone, fluorosilicone and fluorocarbon. It is suitable for both hot air and hot oil over long periods of time. Acrylic has moderate resistance to cut growth and bending cracks. The use of acrylic is limited by its low flexibility at low temperatures. However, some types of acrylic glass may have improved flexibility at low temperatures at the expense of tensile strength and oil resistance.

Main Properties
Excellent resistance to heat and hot oil; excellent resistance to weathering, ozone, sunlight and oxidation; very good resistance to petrol and oil, especially sulphur-containing substances.

Limits
Poor resistance to alcohols, alkalis, solvents and aromatic solvents; limited flexibility at low temperatures; lower resistance to water and steam.
