What is the reason for the thermal conductive silicone sheet with glass fiber cloth?

Everyone who uses the glass fiber thermally conductive silicone sheet will encounter a filament-like substance during the use of the thermally conductive gasket. This is because the thinner the thermally conductive silicone sheet, the worse the tensile resistance and the voltage resistance. Then it decreases. In addition, the thinness of the thermally conductive silicone sheet is too low, and it is easy to tear due to poor stretch resistance during use. Therefore, the thinner thermally conductive silicone sheet will use glass fiber to enhance the tensile and voltage resistance of the product.

Silicone sheet with glass fiber is an ultra-thin thermal conductive material with high performance and stretch resistance. The thermal conductive silicone sheet with glass fiber is based on glass fiber and silica gel, and contains a compound of silicon resin, boron nitride and glass fiber. After using glass fiber, the thermally conductive silicone sheet has good toughness and sturdiness, and enhances the functional effects of high shear strength, puncture resistance and tear resistance. Moreover, it does not affect the multi-style thermal performance of the thermal conductive material itself, and is widely suitable for the application of any electrical and electronic equipment. In the field of thermal conductive materials, fiberglass cloth is widely used.

So why add glass fiber cloth as a reinforcing material on the basis of thermally conductive silicone sheet? There are mainly the following reasons, let's take a look!

low cost

Compared with other glass fiber materials, glass fiber is very affordable and cost-effective. And its production process is relatively simple compared with other glass fiber manufacturing technologies and media. In addition, non-corrosiveness and durability reduce the cost of fiberglass maintenance and warranty work. Later, the end product is lighter and stronger than the alternative materials, and it saves transportation and storage costs. Therefore, it is very suitable to apply glass fiber to high-consumption products like thermal silica gel.

Strong stability

Fiberglass and composite materials have one of the higher strength-to-weight ratios that can be used to make components. The researchers tested that glass fiber is stronger than metal steel. Manufactured from glass fiber components to build a finished product with direct strength far exceeds the use of standard injection molding or non-reinforced plastics or materials. Glass fiber is also suitable for high strength in extreme environments. Glass fiber also has extremely stable chemical properties. No rust, highly resistant to acid and alkali corrosion. The non-corrosive performance of glass fiber is superior to that of metal. When exposed to extreme temperatures, such as salty or humid air, high temperature and strong sunlight, or acid and alkaline chemicals. Glass fiber can last longer and perform better than most available alternatives. And this performance principle is also applicable to the application of thermally conductive materials.

Product appearance meets various needs

With the continuous development of technology, glass fibers and composites are coated in the mold with special treatments of various colors and textures to achieve various appearances and colors required by customers. Glass fiber and composite parts can be made into flat, semi-gloss or high gloss. So as to meet the appearance requirements of thermally conductive silicone sheets and various thermally conductive materials.

Many times, we always receive some special requirements from customers in the process of supplying products. While ensuring thermal conductivity, we also require adding reinforcement materials, whether it is glass fiber, single-sided adhesive, double-sided adhesive, Aluminum foil, copper foil, single-sided PI film, graphene, etc. are all to provide customers with a more convenient product experience, better product quality and ultimately meet customer application requirements. This is not a professional thermal material production. Do manufacturers really need to do it?
