【Basic Knowledge】 "Heat Resistant!" The Heat Resistance of Repco Mica 【Study Edition】

【Basic Knowledge】 "Heat Resistant!" The Heat Resistance of Repco Mica 【Study Edition】

One of the characteristics of mica is its heat resistance! By using it as a filler, it is possible to enhance the physical properties against heat! It is also gaining attention as a non-combustible filler.

Heat resistance Utilizing the heat-resistant properties to enhance the heat resistance of products. Additionally, it is advantageous that no physical property changes occur even under high temperatures during molding. Mica exhibits different physical properties against heat between phlogopite and muscovite. However, both possess strong heat-resistant properties. [Phlogopite] - Melting point: 1500°C - Dehydration start temperature: 800°C [Muscovite] - Melting point: 1200°C - Dehydration start temperature: 350°C As shown above, phlogopite has even stronger heat-resistant properties. Furthermore, it is gaining attention as a non-combustible filler. Mica has a high aspect ratio and excellent barrier properties. By using it as a filler, the non-combustible effect is achieved, which can enhance the fire resistance of paints and resins. Additionally, there are specially processed micas to further enhance their heat resistance.

【Basic Knowledge】Repkomica with excellent sliding and slipping properties (friction materials)【Study Edition】

【Basic Knowledge】Repkomica with excellent sliding and slipping properties (friction materials)【Study Edition】

Mica is used as NAO material for brake pads! Since 1990, mica has been used as a filler instead of asbestos.

Sliding properties (slip properties) Enhances the sliding characteristics of molded products and smoothens the surface. Mica is mainly used as the NAO (Non-Asbestos Organic) material for brake pads. Since the discontinuation of asbestos in 1990, mica has been the filler that replaced it. With mica's unique moderate friction effect, it can prevent squeaking, reduce slipping, and eliminate abnormal noises. Repco mica is also used primarily in friction materials, as well as in rubber, mold release agents, and adhesives. Feel free to download for more detailed information. 　　　　　　　　　↓↓↓↓↓↓↓

[Basic Knowledge] Perfect Compatibility with Repcomica! Plastic Edition

[Basic Knowledge] Perfect Compatibility with Repcomica! Plastic Edition

Excellent compatibility with Maika! General-purpose plastic edition.

The performance itself is not particularly high, but it refers to plastics (thermoplastic plastics) that are inexpensive and used/consumed in large quantities for everyday items. It features a relatively simple structure (composed only of a main chain of carbon), heat resistance of about 100°C, and the ability to change shape freely. It accounts for about 80% of Japan's plastic production. Types of general-purpose plastics include: PVC (polyvinyl chloride), PS (polystyrene), ABS, AS, PMMA (acrylic), PE (polyethylene), PP (polypropylene), etc. The representative general-purpose plastics that are particularly produced and consumed in large quantities are commonly referred to as the "five major general-purpose plastics": PVC, PE (HD-PE, LD-PE), PS, and PP. It also has good compatibility with mica, and is used as a filler in various resins. *We handle various sizes and grades of mica products, focusing on gold mica (S grade) and white mica (M grade). Mica has good compatibility with various materials such as plastic resins, paints, rubber, films, sealing materials, adhesives, and more.

[Basic Knowledge] Rigidity (Bending Elasticity) and Dimensional Stability of Lepcomica [Study Edition]

[Basic Knowledge] Rigidity (Bending Elasticity) and Dimensional Stability of Lepcomica [Study Edition]

The rigidity (bending elasticity) that is a characteristic of mica! It also has a small molding shrinkage rate and excellent dimensional stability, making it suitable for various industrial parts!

Rigidity (Bending Elasticity) Improves product strength and enables resistance to bending and twisting. Dimensional Stability Reduces shrinkage rate to prevent warping and cracking, and minimizes molding shrinkage to provide surface reinforcement effects. Mica balances molding shrinkage in both 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, sealing materials, adhesives, gasket materials, and friction materials.
