Kaolin in plastics provides smooth surface, dimensional stability and resistance to chemical attack. It also acts as a rheological modifier and functional filler. Kaolin also conceals conceals fibre reinforcement patterns and reduces shrinkage and cracks during polymer compounding and shape forming. One of the major application of kaolin is in PVC cables where it is used to improve electrical properties.
Kaolin adds strength, abrasion resistance and rigidity to rubber. Kaolin finds extensive use in high value thermoplastic elastomers for a variety of applications and in rubber insulation on high voltage power lines. Kaolin also applied in films where they impart anti-blocking or infrared absorption characteristics. Fine kaolin is one of the major additives used in the manufacture of automotive parts based on engineering thermoplastics.
EICL has normal and ultra-fine grade calcined clay for plastic application. Calcined clays are used in plastic for imparting specific functional properties like anti-blocking and IR-blocking. The controlled particle size distribution and irregular shape of calcined clay impart anti-blocking property in plastics.
SMK – Surface modified Kaolin used in plastics , SMK improves the dispersion of the filler and hydrophobicity of filler surface ,which aids in the increased mechanical strength of plastic material
Himacab – Recommended for use in EPDM and EPR Rubber cables and LT & HT PVC cables and other plastic polymers to improve the volume resistivity of the insulation compound.
Himapol – As a performance filler to improve the volume resistivity of medium and high voltage PVC cable compounds.
