TECATEC PEI GW50 PL V01 natural

Glass fibre reinforced PEI composite plate

TECATEC PEI GW50 PL V01 natural is a PEI composite that is based on the polyetherimide Ultem resin. Due to the 50 vol% reinforcement with glass fibre fabric, this thermoplastic offers extreme mechanical strength and thermal dimensional stability. The glass fibre reinforcement enhances the stiffness and strength when compared to unreinforced or short-fibre reinforced PEI, while keeping costs competitive.

The reinforced thermoplastic is inherently flame retardant and therefore suited for the use in transportation interior, such as in buses, trains, aircrafts and urban air mobility vehicles. Furthermore, it can be painted for a custom finish.

The glass fibre reinforcement combined with the electrical insulating properties of the Ultem material leads to an ideal electrical insulation profile of the composite material. Due to its excellent chemical resistance, TECATEC PEI GW50 PL V01 natural retains its strength even when exposed to most solvents. The high glass transition temperature of PEI makes TECATEC PEI GW50 PL V01 natural suitable for high-temperature applications where physical and mechanical properties have to be retained at temperatures of up to 200 °C.

TECATEC PEI GW50 PL V01 natural are plates made from glass filled plastic. They are available in two fibre architectures in relation to the woven glass fibre material used as reinforcement. While V01 refers to a US 7781 satin weave, which is well known in the aerospace industry, the V02 variant has a twill 2/2 weave which is more suitable for industrial applications. Both are available in sizes up to 525 x 625 mm and thicknesses from 1 mm up to 95 mm and are available with no minimum order requirement.
