Momentive Performance Materials Silopren™ LSR 2620 Liquid Silicone Rubber - Fast Cure / High Tear
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)

Material Notes: This LSR elastomer is a general purpose, two-component, platinum (addition/heat) curable, and pumpable silicone elastomer that can be molded and cured with very fast cycle times, at elevated temperatures. The molding process allows for complex part geometry and exact dimensions. LSR elastomers are generally suitable for short cycle time injection and full automatic flash-less processing. Color pastes are available to pigmenting addition cure productions of LSR's.

All LSR grades are platinum cured materials which are mixed in a 1:1 ratio by weight.

Industries and Applications: The Momentive portfolio of products is used for a wide variety of applications in the Automotive, Aviation and Aerospace, Consumer Goods, Consumer Electronics, Healthcare and Energy Industries.

LSR 2620 is a fast cure, high tear grade.
