WACKER at EXPOBOR: to Present ELASTOSIL LR 3022/60, a Silicone Rubber for Sealants and more

Munich -- WACKER, the Munich-based chemical group, is showcasing numerous new and time-tested silicone rubber grades at EXPOBOR 2014. ELASTOSIL LR 3094/60 liquid silicone rubber will be one of the highlights at the WACKER booth. It makes cost-effective, large-scale production of spark plug boots possible. Another eye-catcher will be coolant-resistant ELASTOSIL LR 3022/60. The liquid silicone rubber, which is presented at EXPOBOR for the first time, can be used to make molded gaskets for engine cooling circuits. Another innovation is magnetite-filled ELASTOSIL R 781/80 solid silicone rubber. This product enables the manufacture of molded parts and profiles that adhere magnetically. EXPOBOR 2014 will take place from April 23 to 25 in Sao Paulo, Brazil.

One of the novelties WACKER will show at EXPOBOR 2014 is ELASTOSIL LR 3022/60. Coolant- and heat-resistant, the new liquid silicone rubber is especially suitable for producing gaskets for installation in engine cooling systems.

At the WACKER booth, the spotlight will be on ELASTOSIL LR 3094/60. This fast-curing liquid silicone rubber is designed for cost-effective, large-scale production of spark plug boots. Its rubber-elastic cured rubber grades feature excellent heat resistance, good mechanical properties and very good dielectric properties. Spark plug boots and other technical products made of ELASTOSIL LR 3094/60 do not require postcuring.

Cured ELASTOSIL LR 3094/60 rubber grades easily withstand temperatures of ?55 to +210 degrees Celsius. A spark plug boot made of this silicone always has the same properties, whatever the temperature to which it is exposed in practice. It has a long service life even under continuous heat exposure. Spark plug boots made of ELASTOSIL LR 3094/60 offer effective protection against road spray, moisture and dirt. They provide reliable electrical insulation, achieve high dielectric strength and prevent the development of corona effects.

Coolant-Resistant: ELASTOSIL LR 3022/60

WACKER is also introducing the new ELASTOSIL LR 3022/60 silicone grade at EXPOBOR. This liquid silicone rubber enables the manufacture of molded gaskets that can be used in automotive engine cooling systems. In its cured state, the new grade retains a low compression set, even under long-term load in direct contact with coolants. This ensures excellent, lasting sealing properties.

Standard silicone elastomers are not really suitable as sealants in the hot areas of engine cooling circuits. As soon as these elastomers come into contact with a coolant ? usually a water/glycol mixture of over 100 degrees Celsius ? some of their key properties for leak-tightness, such as elasticity and rebound resilie
