Silbione®  LSR SELECTTM products are supplied as individual component materials.  These are intended to be used in conjunction with Silbione® LSR SELECTTM CONTROL and Silbione®   LSR SELECTTM CATA.  These components must be mixed with specialized, but readily available dosing systems.  The molder can control the dosing of Silbione®   LSR SELECTTM CONTROL and Silbione® LSR SELECTTM CATA to achieve a faster curing material.


Cure does not begin until the Silbione®   LSR SELECTTM CATA is introduced into the stream of material. Addition of Silbione®   LSR SELECTTM CONTROL will determine the necessary cure time.

Shut Down:

To shut down, immediately stop any further incorporation of Silbione®  LSR SELECTTM CATA.  If the level of Silbione®  LSR SELECTTM CONTROL has been less than 6%, simultaneously increase it to at least 6%.  Continue molding until parts lack the ability to cure well.  At this point some additional purging of the barrel and cold runner may be necessary.

SILBIONE LSR SELECT ™ 50 may be stored for up to 24 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


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

Silbione® LSR SELECTTM platinum-catalyzed silicone elastomers are designed for liquid injection molding and designed for manufacturing precision molded parts for industrial, consumer, and automotive applications.  They may also be used for overmolding onto other polymers.   Silbione® 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' Silbione® 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 Silbione®  LSR SELECT™, you CONTROL your destiny.
