Our company FuQiang (FQ) is committed to developing a series of thermal runaway management parts for new energy vehicles. The following will introduce new energy vehicle battery mica safety parts. It is a solid wall after the battery thermal runaway occurs, continuing to ensure the safety of passengers. Our technology improves battery thermal runaway management performance, insulation, durability, and sustainability. From EV batteries, battery modules to battery packs and complete vehicles, we can customize professional solutions for customers, ensuring product performance while providing fast and comprehensive services.
The biggest advantage of our company is that we have professional equipment that can process, punch and shape a variety of different materials. Our company's manufacturing capabilities are among the top five in China's auto parts processing, so you can safely leave the project to us. If necessary, we can set up factories overseas to assist your company with supporting services. Below I will classify mica based on its hardness and characteristics. These mica materials can be used between battery modules of new energy vehicles or cell to cell. Mica is divided into hard mica composite materials and soft mica composite materials according to the composite material and hardness.
一. Hard mica composite material:
Our Hard mica composite material is mainly used in the Battery Packs cooling fins of new energy vehicles. It can be used for fire protection, heat insulation, high pressure resistance, corrosion resistance, and waterproof functions.Compared with general insulation materials, the outstanding advantages of hard mica composite materials are:
Excellent high temperature resistance and insulation performance, the breakdown voltage still maintains 15kV/mm in the use environment with a temperature of 500-1000℃;
Excellent mechanical properties, with good bending strength and hardness;
Stable chemical properties, excellent acid and alkali resistance and aging resistance;
Excellent environmental performance, does not contain toxic and harmful ingredients, and does not produce toxic gases at high temperatures;
Excellent processing performance, can be processed into various shapes without delamination.
1.Hard mica board
Rigid mica board is a rigid plate-shaped insulating material made of mica paper and high-performance silicone resin bonded and pressed at high temperature. The mica content is about 90%, and the silicone resin content is about 10%. Hard mica board has the characteristics of high strength, good performance, less smoke and little odor.
2.Soft mica board
Soft mica board is a soft plate-shaped insulating material made of mica paper and high-performance silicone resin that are bonded and pressed at high temperature. The mica content is about 90%, and the silicone resin content is about 10%. The soft mica board has good elasticity and flexibility at room temperature. It can be folded dozens of times, curled into various shapes, and placed under heavy objects without breaking. According to customer needs, the voltage capability can be increased to 1-2 times the conventional standard value. Depending on the required toughness, fully soft boards and semi-soft boards can be customized.
3. Smooth mica board
Smooth mica board is a rigid plate-shaped insulating material made of mica paper and high-performance silicone resin that are bonded and pressed at high temperature. The mica content is about 90%, and the silicone resin content is about 10%. Smooth mica board is made using special technology. The surface of the hard mica board has a mesh structure. In comparison, the surface of this series of mica boards is flatter, smoother and more beautiful.
4. Extra thick mica plate
Ultra-thick mica board is a high-strength insulating material made of mica paper and high-performance silicone resin bonded and pressed at high temperature. The thickness is more than 5mm and can reach up to 100mm. Compared with general insulation materials, the outstanding advantages of ultra-thick mica boards are: superior thermal insulation performance, fire resistance temperature of 500℃~750℃, and low thermal conductivity; oil-proof and anti-corrosion, environmentally friendly and non-toxic, and a substitute for asbestos; bending resistance It has high strength and can be processed into various special-shaped parts using lathes, milling machines, drills, etc. without delamination.
二. Soft mica composite material:
Our soft mica composites are mainly used in thermal insulation and sealing of new energy vehicle batteries. In addition, it can also be used in other areas of the car that are insulated and resistant to high temperatures.The main characteristic:Excellent high temperature resistance and insulation properties, phlogopite rolls and synthetic mica rolls are guaranteed not to be broken down within 90 minutes at temperatures of 750-850℃ and 950-1000℃ respectively, and in a voltage environment of 600-1000V;
Stable chemical properties, excellent acid and alkali resistance and aging resistance;
Excellent environmental performance, does not contain toxic and harmful ingredients, and does not produce toxic gases at high temperatures;
Excellent mechanical properties, with good tensile strength and flexibility;
Smooth and neat appearance, good processability, products can be customized according to customer requirements.
1. Phlogopite roll
Mica roll is a roll-shaped insulation product made of high-quality phlogopite paper and synthetic mica paper as the base material, glass fiber cloth or ceramic fiber reinforcement material, bonded with silicone resin, baked and dried at high temperature.
2.Synthetic mica roll
Mica roll is a roll-shaped insulation product made of high-quality phlogopite paper and synthetic mica paper as the base material, glass fiber cloth or ceramic fiber reinforcement material, bonded with silicone resin, baked and dried at high temperature. We can make it into various two-dimensional plane shapes according to customer needs.
3. Ceramic mica roll
Mica roll is a roll-shaped insulation product made of high-quality phlogopite paper and synthetic mica paper as the base material, glass fiber cloth or ceramic fiber reinforcement material, bonded with silicone resin, baked and dried at high temperature. Mica rolls can be made into various two-dimensional plane shapes according to customer needs.
The above are the main mica products of our company. We have the most professional molding equipment and technical team to make mica gaskets. We generally stamp the material through molds to make our mica into the shape our customers need. Among them, we can add glass fiber to the product, attach tape to the product, or stack it with other materials: for example, it can be combined with silicone rubber, ceramic silicone rubber, PC sheets and other materials. We believe that our mica boards will be your best choice in new energy vehicle battery thermal insulation protection solutions.
