It is transparent, flexible and elastic and can be ground to very fine particles with a high-aspect ratio which are specially suited for reinforcing filters. It is chemically inert and can easily resist actions of heat, light, water, oil, solvents, alakalies and various chemicals.

In formed thermoplastics mica promotes uniform cell structure, persuming acting as a nucleating agent, lower its density, reduce cost, add low temperature impact resistance and reduce flammability.

The addition of mica in plastics normally increases its tensile and flexural strengths. Mica has a pronounced effect on modulus of elasticity at the same time decreases its elongation. It further improves the notched impact strength of same polymers.

The incorporation of mica reduces thermal expansion and helps to eliminate the non-uniform thermal shrinkage and causes warping it also reduces mould shrinkage and facilitates mould release. Mica has a variable and generally negative effect on impact strength.

Mica enhances the dielectric, heat-resisting and insulating properties of plastics. Mica fillers improve deflection temperature. Mica, being a natural inorganic mineral, is among the most radiation resistant dielectric material and thus is able to absorb upto 80% of incident ultra-violet radiation protecting plastics against degradation.

Mica, being a stable and completely inert to the action of water, acids (with exception of concentrated sulphuric/phosphoric acid mixtures and hydrofluric acid), alkalies, conventional solvents, oils and virtually unaffected by atmospheric action. Its flake like form and virtually unaffected by atmospheric action. Its flake like form provides an excellent barrier to chemical attack and therefore is most suitable for use in polyster or spray protective coatings.

Mica provides cost effective improvements in the critical properties for a wide range of thermoplastic and thermoset composites including those based on PP, HDPE, HMWPE/PP/PE, PA, TPX, ABS, HIPS, PST, PBT/PET, PES, PVDE, PVC, SAN, etc.
