レプコ レプコ 本社工場
The rigidity (bending elasticity) that is a characteristic of mica! It has a low molding shrinkage rate and excellent dimensional stability, making it suitable for various industrial parts! Rigidity (bending elasticity) Improves the strength of products and allows them to withstand bending and twisting. Dimensional stability Suppresses shrinkage to prevent warping and cracking, reduces molding shrinkage and provides surface reinforcement effects. Mica balances molding shrinkage in both the MD (machine direction) and TD (transverse direction). Due to the above characteristics, it is used in various applications such as automotive parts, electronic devices, films, marine coatings, exterior materials, interior materials, sealants, adhesives, gasket materials, friction materials, and more. *We handle various sizes and grades of mica products, focusing on muscovite (S grade) and phlogopite (M grade). Mica has good compatibility with various materials such as plastic resins, paints, rubber, films, sealants, and adhesives. Please feel free to contact us.

Repkomica S Series (Mica Gold)

General grade with high purity and high aspect ratio. Phlogopite, derived from the Greek word phlogopos meaning "like flame."

The "Repkomica S Series" is a product made from natural mica that has been refined and crushed at a domestic factory. It maximizes the high elasticity inherent in natural mica through manufacturing techniques developed over many years, resulting in a high aspect ratio (average particle size/thickness), which is a key feature of flake fillers. By being incorporated into industrial materials such as plastics, paints, and rubber, it is expected to provide various functionalities centered around rigidity, dimensional stability, and heat resistance. 【Features】 ■ Long-term supply stability due to abundant reserves ■ Quality stability through domestic production system ■ No crystalline silica detected (detection level: below quantification limit) ■ Various grades available based on average particle size ■ Flexible response to custom grade orders and surface treatments ■ Short delivery times supported by domestic bases Please feel free to download for more detailed information.          ↓↓↓↓↓↓↓
