The Importance of Contact Moulded Fibreglass Manufacture
Industry Standard for Best Chemical Resistance
Fibreglass laminates made by contact moulding, also called hand lay-up, have the highest resin to glass ratios of 70:30 when compared to alternative manufacturing methods. As it is the resin that gives a fibreglass laminate its chemical resistance, this high ratio makes contact moulding the preferred fibreglass manufacturing process when the highest degree of chemical resistance is required. In contact moulding, the main laminate is reinforced mainly with non-continuous glass fibre, and this limits the spread of any chemicals within the laminate should it be exposed or damaged.
