Material
Accura® 25
Accura® 25 is a white, polypropylene-like resin (Shore 80D) with good elongation and shape retention, used to simulate and replace CNC-machined polypropylene parts such as snap-fits and functional assemblies.

About
Accura® 25 is a hard (Shore 80D) resin formulated to simulate polypropylene. For a rigid resin it is relatively ductile, which suits snap-fits and functional assemblies.
Compared with real polypropylene, its notched impact strength is at the low end of the range and heat deflection is only about 51–63 °C, so it suits prototypes and low-volume parts rather than high-impact or hot environments.
Accura® 25 is a good option for snap-fit prototypes, functional assemblies, and master patterns for vacuum casting.
