Brittle glass and/or ceramic body for example for a cooking surface, is held in a thermoplastic frame with an elastomer content with a relaxation effect to reduce breakages to minimum levels

摘要

The body of a brittle material, such as glass and compound glass, is contained in a thermoplastic frame of a material containing a proportion of an elastomer with a relaxation effect. The assembly takes up the forces (3) on the frame and the forces (4) in the contained glass body. The shaped body is of glass, ceramic or glass/ceramic materials. The thermoplastic frame material has a relative temperature index (RTI) value of - 120 deg C and a temporary temperature loading of - 200 deg C. The thermoplastic material can contain one or more filling materials. The thermoplastic elastomer is treated to give increased adhesion with the glass body, and is incorporated into the thermoplastic material at a rate of 1-50 wt.%. An Independent claim is included for a manufacturing process, where the holder frame is formed by injection molding round the glass body.
