Some have specific performance characteristics such as flame resistance, high temperature resistance, and very high impact resistance.

A unique casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03” to 0.50” (0.075cm to 1.27cm). TASK™ 4 exhibits very low shrinkage which is why this plastic has become a favorite of precision prototype and design professionals throughout the world.
