New & Improved 

   PT Flex Series Liquid Rubbers are polyurethane casting rubbers specifically designed for making prototypes as well as functional rubber parts.  Unlike many other Polytek® polyurethane rubber products, these castable rubbers are low in viscosity and are fast-setting so they can be demolded rapidly.

    New & Improved PT Flex casting rubbers no longer contain mercury.  DO NOT MIX New & Improved PT Flex rubbers with previous versions of PT Flex Rubbers.
