Wolfa has been been producing and processing glass fiber reinforced plastic (GRP) for almost sixty years. The glass fiber compound and the thermosetting polyester resin guarantee greatest stability and shape retention even under extreme conditions. GRP has become an integral and indispensable component in car engineering, shipbuilding and the aerospace industry. Wolfa uses this material as a sheet molding compound (SMC), a mixture of polyester resin, mineral filling material and a high portion of glass fibers. Unlike traditional thermoplastics such as PVC or polypropylene, our SMC cannot be reshaped by heat once it has hardened, and retains its sturdy and stable characteristics even when exposed to extreme temperature fluctuations.
