PRODUCT DESCRIPTION:
Flex 90 is a urethane casting compound that is specifically formulated for high abrasion and impact resistance. It is recommended for use for the production casting of highly wear-resistance parts and linings. This product is a safe, easy to handle, room temperature mixing and curing system that does not contain TDI, MDI, MDA, or MOCA. Flex 90 is relatively insensitive to typical environmental moisture and will make good void free parts without the problems that some conventional urethane systems exhibit. Because of this product’s exceptional toughness and abrasion resistance, casting made with Flex 90 are particularly suitable for mineral process and metal forming industries.
PRODUCT HIGHLIGHTS:
- Abrasion-resistance parts and linings
- Bumpers and rub rails
- Paper feed rollers
- Potting and encapsulation applications
- Semi-flexible molds
- Metal forming die facings
- Holding fixtures
- Machinery base pads
