PPR ELITE 90

Description
Exysos PPR ELITE 90 is a low-viscosity liquid photopolymer that produces water-resistant, durable and accurate three-dimensional parts. PPR ELITE 90 has a white, opaque appearance with performance that mirrors production plastics like ABS and PBT.

Applications
PPR ELITE 90 is ideal for many applications in the automotive, aerospace and consumer product industries. PPR ELITE 90 is successful in creating functional prototypes, humidity / water-resistant concept models, and durable low volume production parts.
