Leather Printing Roller Silicone Rubber - China

Liquid silicone rubber (LSR) is very low viscosity silicone that can be

injection molded or cast into silicone rubber sheets.

'Liquid' is

explicit in the name to differentiate LSRs from high consistency gum

based silicone products.

LSRs are addition cure / platinum cure systems

in contrast with most gum based silicones that are peroxide cured.

In

its raw uncured form, LSR is two parts liquid that are mixed together

(mixing of Part A and Part B starts the curing) and heated to

accelerate the curing process.

Raw gum based silicones look and feel

similar to clay.

LSRs are generally injection molded or cast while gum

based silicones are typically compression molded.

Note that injection

molding of liquid silicone rubber is the inverse of molding

thermoplastics; room temperature liquid silicone compound is injected

into and cured in a hot mold vs.

plastic pellets melted into hot liquid

and forced into a cooled mold.
