LSR SELECT ™ 20

LSR SELECTTM is a patented, advanced system of materials designed to enhance the operation, control, flexibility, and productivity of LSR molding processes.

 LSR SELECTTM platinum-catalyzed silicone elastomers are designed for liquid injection molding.  LSR SELECTTM  materials must be used in conjunction with curing additives to achieve rapid cure. 

 Available in a range of hardnesses from 20 to 70 durometer – Shore A, Elkem Silicones' LSR SELECTTM materials offer the same distinctive advantages of easy processing and release as our 2 part LSR products.  In addition, this proven system gives you CONTROL to optimize your cure kinetics improving productivity and flexibility to achieve your precise results.

Now you can also create a repeatable, unique and precise durometer blend, as well as expand your range of applications for low temperature cure.  With LSR SELECT™, you CONTROL your destiny.

LSR SELECT™ silicone elastomers are designed for manufacturing precision molded parts for industrial, consumer, and automotive applications.  They may also be used for overmolding onto other polymers.
