Fluoroelastomer Specialists
Ethylene-propylene elastomers (EP elastomers) are one of the most widely used and fastest growing synthetic rubbers, after polybutadiene rubber and styrene-butadiene rubber (SBR). Ethylene-propylene elastomers have outstanding resistance to ozone, aging, weather and high temperature; good low-temperature flexibility and excellent electrical properties. Ethylene-propylene elastomers are also resistant to polar solvents like acids, water, phosphate esters, alkalies and many ketones and alcohols. Ethylene-propylene elastomers have lower densities than all other elastomers and plastics and can accept high loadings of reinforcing agents, fillers and plasticizers, making them an economical choice for a wide range of applications. Ethylene propylene elastomers have use in wide range of industries including: building and construction, automotive, plastic modification, lubricant additive, wire and cables and tyres and tubes among others. Ethylene-propylene elastomers are sold under the brand names Norde, Keltan and Royalene among others.
Ethylene-propylene elastomers have a large number of uses due to the numerous ways in which the polymers can be designed, for example; it is used in automotive weather-stripping and seals, radiators, glass run channels, garden and appliance hoses, belts, tubing, rubber mechanical goods, roofing membranes, plastic impact modification, thermoplastic vulcanisates and motor oil additive applications. Ethylene-propylene elastomers are used as an insulator for high-voltage cables since they have superior insulative characteristics over more traditional cables, such as cross-linked polyethylene, enabling a smaller cross sectional area for the same load carrying capacity. The cable is well suited to applications where regular cable movement is required such as in the mining industry. Polymerization and catalyst technologies in use today provide the ability to design ethylene-propylene elastomers to meet specific and demanding application and processing needs.
