1.Description

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

Well-balanced physical properties, difficult-inflammability and excellent dimensional stability of Hei-t 8263 makes it sible to apply this innovative product as a flame retardant type t 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-t 8263 is also suited for short run production.
