Resin Transfer Moulding provides several advantages over traditional methods of making fibreglass products.
The plastic component of fibreglass is polystyrene. In the finished product it is quite safe, but fibreglass workers are exposed to styrene monomer which is regarded as a hazardous chemical. RTM produces less than 10% of the emissions of styrene compared with hand lay-up. In fact, the pollution caused by traditional fibreglass open moulding techniques is the sole reason why Apogee pursued the art of RTM. Governments around the world are beginning to place restrictions on open moulding techniques. In contrast, RTM is recognised as being virtually pollutant free, and the most acceptable fibreglass manufacturing technique.
Our employees aren’t the only ones to benefit from RTM. Aside from the reduction in air pollution, RTM moulds don’t require any consumables beyond the resin and glass fibres. The precise engineering tolerances reduce overuse of resin, and resin wastage is limited to 1% of the total used.
