Syntac® 450

Syntac® 450

Syntac® 450 epoxy composite tooling material a temperature resistant material for forming packaging with high strength and clarity and maintains its hardness right up to the maximum running temperature while exhibiting excellent abrasion resistance. Syntac® 450 is forming higher temperature plastics, especially when trying to maintain clarity.

High temperature 450 °F (232 °C)

Available in a wide range of block, rods and sheets

Improved clarity

Elimination of swirl and chill marks

Increased strength compared to other epoxy syntactic material

Key Applications

Syntac® 450 is easily machined using standard shop tools and offers a lightweight, durable and cost effective alternative to wood, felt and aluminum.

Thermoforming high temperature plastics
