Achieve Superior Resin Flow and Wetting Properties with 450/PP250/450 Glass Fiber Fabric

A three-dimensional glass mat consisting of a PP core sandwiched between two layers of CSM. This sandwich core materials is specifically designed for the closed moulding process using techniques such as RTM & VIP for the production of fire resistant FRP composite parts.

450/PP250/450 is a high-permeability glass fiber fabric for the production of composite parts by infusion or RTM (injection).

It is produced with two layers of 450 g/m2 Glass Chopped Strand Mat (CSM) and a 250 g/m2 nonwoven polypropylene yarn (pp core mat) that improves and accelerates the flow of the resin through the fabric in closed mould applications.

Suitable for thermosetting resins such as polyester, vinyl ester or urethane acrylate.

Product Benefits

Can satisfy the highest level of fire performance, including EN45545-2 for rail Industry

Compatible with UPE and Phenolic resin systems

Excellent wetting and resin flow properties

Compatible with highly filled and high viscosity resins

Excellent fit even in complex shaped parts

Use looser stitches and tensions to make it easier for workers to maneuver around the corners of complex molds.

The weight of each layer of material can be customized according to the specific requirements of customers.

Fabric widths range from 500-2600mm

Packaging

Each roll is wrapped around a 77 mm (3 in.) ID cardboard tube, individually wrapped with polyethylene plastic film, placed in a carton, and individually labeled for identification.

One carton per roll, usually stacked vertically on pallets, 9 or 12 cases per pallet.

The product should be stored in a cool and dry condition.
