Engineering Thermoplastics

Imerys Kaolin is an important supplier of high quality mineral additives to the Engineering Thermoplastic Composites industries throughout the world. Our specialty designed surface modified kaolin clays are supported by a high standard of technical service, product development and research from a team of highly experienced scientists and specialists in the application of kaolin’s in the high performance plastic markets. We are able to provide guidance on how to compound our materials into final applications.

A principal feature of Imerys Kaolins is their high purity, consistency of wide range size distribution and aspect ratio products: from Super Ultra-Fine to very high Hyperplaty aspect ratios, including Hydrous (water washed) and Calcined grades. Our specialized technical knowhow on surface modification provides additional enhancement to final composite performance. Product development data on Engineering Alloys (Polyamide based composites), are targeting chopped glass fibers extension and replacement, where these functional additives can improve compounding cost, dimensional stability, surface appearance and provide excellent balance of mechanical properties (impressive improvement in stiffness – flex modulus, and tensile strength and maintaining superior impact strength values).
