TBPA-UPR-286N;Tetrabromophthalic Anhydride
Introduction & Specs
| Description | TBPA-UPR 286N is a Tetrabromophthalic Anhydride-based flame-retardant unsaturated polyester resin with moderate reactivity and high viscosity. It has good processability, fast curing speed, and the cured products have good flame retardancy and mechanical strength. It is particularly suitable for pultrusion molding to manufacture fiberglass products with flame retardant requirements. |
