First in the DryPreg range
Thursday, 18 June 2015

GF Industries based in Greensboro, North Carolina, a manufacturer of woven and nonwoven materials from high performance fibres, is introducing a new thermoplastic composite material called PolyPreg.

PolyPreg is a woven co-mingled glass/polypropylene fabric that can be directly consolidated with the addition of heat and minimal pressure into a high strength composite part. Said to be the only domestically produced composite of its kind, parts made from PolyPreg can be used in various applications in the automotive, building, construction, marine, military and defence, sports, leisure and transportation industries.

The material is soft and conformable to complex shapes and is available in 750 or 1,500 gsm and natural or black colours.


Laminated, moulded or pultruded processing conditions are recommended at a temperature of 400°F and a cool pressure of 20 to 100 PSI, making processing easy. With an unlimited shelf life PolyPreg requires no cold storage and can withstand temperatures up to 300°F.

UV stable in nature, the material maintains its colour and form upon exposure to sunlight and is less likely to become brittle, crack or become discolored. Additionally, PolyPreg produces no emissions and is fully recyclable.

PolyPreg is the first product to be released in the DryPreg™ product line, a comprehensive offering of new thermoplastic materials developed by BGF. DryPreg products currently in development will combine other high performance fibres and resin systems to offer a varied line of thermoplastic composite materials. Additional products are slated for release later this year.
