A continuous fiber-reinforced polycarbonate composites with enhanced flame retardance

News International-French

2 Mar 2015

The Bond Laminates GmbH, a subsidiary of specialty chemicals company Lanxess, has expanded its Tepex range of continuous-fiber-reinforced thermoplastic high-performance composites to include halogen-free flame-retardant versions with a polycarbonate matrix.

Tepex FR grades demonstrate high flame retardance in tests to fire safety standard UL 94 of range US testing organization Underwriter Laboratories. They achieved the top V0 classification on UL’s Yellow Card at specimen thicknesses between 0.4 and 2 millimeters

Jochen Bauder, Managing Director of Bond-Laminates sees major potential for applications in the consumer electronics industry. The new composites will form a major highlight of the Lenxess presentation at the JEC Europe 2015 show in France and the NPE plastics trade fair in the United States.

High stiffness and strength
Tepex FR is supplied primarily in thicknesses of between 0.5 and 1.2 millimeters. Variations are available with glass, carbon or glass/carbon fiber reinforcement. The fiber volume content lies between 45 and 55 percent. The composite sheets exhibit excellent mechanical properties. For example, the flexural modulus of the carbon-reinforced grades lies between 40 and 54 GPa depending on the fiber content, and the modules of the glass-fiber-reinforced grades between 20 and 24 GPa (DIN EN ISO 178).

An alternative to aluminum, magnesium and injection-molding materials
Their mechanical properties, low weight and ease of processing make these new composites especially suitable for the production of large, thin-walled and extremely stiff housing parts such as those used for notebooks, tablets and TV sets.

The JEC trade fair will take place in Pavilion 7 of Porte de Versailles, Paris, from March 10–12, 2015, and Bond-Laminates will be in Hall 7.3 (stand no. F63).
