Momentive Performance Materials Develops Liquid Silicone Rubber Products

Momentive Performance Materials has come up with a new liquid silicone rubber (LSR) material for use in the automotive industry, called Silopren 2171. The new material is a part of the Silopren series of LSRs, which is resistant to oil.

Silopren 2171 is essentially filled with minerals and is of ‘A’grade hardness. The material exhibits low compression and good tolerance to tear. Its unique properties make it suitable for use in anti-drainback valves and oil seals located under the hood of automobiles.

Olive Franssen, the Global Marketing Director for Transportation at Momentive pointed out that the new material is the result of constant technological advancements at Momentive. He added that the earlier versions of Silopren have performed well in their applications in the automotive industry. He explained that Silopren 2171 has undergone 3000-hours of testing under the ASTM D471 Standard Test Method using IRM 903 oil. This test was conducted primarily to test the ability of rubber and rubber like components to withstand the effects of liquids. Franssen concluded by saying that LSRs used in the automobile industry must come out with excellent results in the ASTM test. Silopren 2171 has already been exhibited at the FAKUMA international trade fair. Apart from efficient physical performance, the material can be considered as a cost-effective replacement for the existing oil-resistant silicones.
