Pultrusion - The UK's Leading Plastic Trade Association

The Pultrusion process starts by pulling/drawing continuous reinforcements (in rovings or mat / roving forms) through a resin impregnation system. Each fibre is coated with a specially formulated resin; the process is controlled to ensure full “wetting out” of the fibre reinforcement. Excess resin is then removed to expel any trapped air and to compact the fibres.
