1.Description

Hei-Cast 8263 is a flame retardant type polyurethane resin for vacuum casting application with the specific properties so far not obtainable with the prevailing urethane cast materials.

Well-balanced physical properties, difficult-inflammability and excellent dimensional stability of Hei-Cast 8263 makes it possible to apply this innovative product as a flame retardant type cast material for the manufacture of prototypes which require UL94 V-0 and 5VA specification and for the monitoring of mechanical strength of the molded parts. Hei-Cast 8263 is also suited for short run production.
