Fibre-reinforced polycarbonate is flame retardant for computers

Visit Lanxess at JEC Europe, Pavillion 7.3 -stand F63.

Continuous-fibre-reinforced thermoplastic high-performance composites in the Tepex range now include halogen-free flame-retardant versions with a polycarbonate matrix.

Lanxess, a Bond Laminates company, claims that the Tepex FR grades demonstrate exceptionally high flame retardance in tests to fire safety standard UL 94 of the Underwriter Laboratories. They achieved the top V0 classification at specimen thicknesses between 0.4 and 2mm, indicating a potential for applications in the consumer electronics industry.

Tepex FR is supplied primarily in thicknesses of 0.5 to 1.2mm. Variations are available with glass, carbon or glass/carbon fibre reinforcement. The fibre volume content lies between 45 and 55%. Flexural modulus of the carbon-reinforced grades lies between 40 and 54GPa depending on the fibre content, and the modules of the glass-fibre-reinforced grades between 20 and 24GPa (DIN EN ISO 178).

They are low weight, require less process engineering than aluminum and magnesium and, compared to injection-moulded component designs, can be used to produce thinner walls so that housings need less installation space, says the company.

The new composites will be presented at JEC Europe, Paris next week (1- to 12 March).

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).
