Spacers for infusion as flow medium

The fiberglass manufacturing industries like boat, yacht manufacturing, rotorblades of wind turbines the resin flows between the reinforcing layers. To keep glass fibre layers separated and provide an open channel for foams and resins to flow easily and quickly through molded parts a flow media is used as spacer. Very thin but still 3-D structure mats, spacers can be used as an infusion mesh or transport medium for the resin. Enka-Spacer, EnkaFusion and Enka-Channel type of spacers are used as both feeder & bleeder material in the production of rotor blades, boat manufacturing and similar composites manufacturing.

PUR foam injection and RTM processes

PUR foam injection or other RTM (resin transfer moulding) processes, a spacer (Enkaspacer) can be used matting, holding the glass fibre layers in place. The automotive industry (and technology related industries) are often making use of on of the various types of this product. Enkaspacer is a widely used spacer in this industry. Enka-Spacer is a flexible and effective product that can speed up the production process and ensures a repeatable high-quality product. It holds the placed glass fibre reinforcement matting between the composite skins in the correct location throughout the process, allows the polymer foam to flow freely through the mould and ensures that both the glass fibre reinforcement and the skins are fully wetted out.

These type of spacer can be used in other industrial applications.
