In the process of using the thermal pads with glass fiber, everyone will encounter a material similar to filaments during the use of the thermal conductive gasket. This is because the thinner the thermal pads, the worse the tensile strength and the voltage resistance performance. Immediately lower, in addition, the thermal pad is too thin, and it is easy to tear during use due to poor stretch resistance. Therefore, generally thinner thermal pads will use glass fibers to enhance the tensile strength and voltage resistance of the product.
Thermal pads with glass fiber is a kind of ultra-thin thermal conductive material with high performance and tensile strength. Thermal pads with glass fiber is based on glass fiber and silica gel, and contains a compound of silicone resin, boron nitride and glass fiber. The thermal pads after using glass fiber has good toughness and strong, and enhances functional effects such as high shear strength, puncture resistance and tear resistance. And it does not affect the multi-style thermal properties of the thermally conductive material itself, and is widely suitable for the application of any electronic and electrical equipment. The most widely used thermal conductive material is glass fiber cloth.
So why add glass fiber cloth as a reinforcing material on the basis of thermal pads? There are mainly the following reasons, let’s take a look!
Fiberglass is very affordable and cost-effective relative to other fiberglass materials. And its production process is relatively simple compared to other glass fiber manufacturing technologies and media. In addition, the non-corrosiveness and durability make fiberglass maintenance and warranty work less expensive. Lastly, the end product is lighter and stronger than alternative materials, saving on shipping and storage costs. Therefore, it is very suitable to apply glass fiber to high-consumption products such as thermal silicone pads.
Fiberglass and composite materials have one of the higher strength-to-weight ratios that can be used to make components. Glass fibers are stronger than metallic steel after the researchers’ tests. Fabricating components from fiberglass builds a direct-strength finished product far beyond using standard injection-molded or non-reinforced plastics or materials. Fiberglass is also suitable for high strength in extreme environments. Glass fiber also has the characteristics of extremely stable chemical properties. Does not rust and is highly resistant to acid and alkali corrosion. The non-corrosive properties of glass fibers are superior to those of metals. When exposed to extreme temperatures, such as salty or humid air, high temperature and strong sunlight, or acidic and alkaline chemicals. Fiberglass lasts longer and performs better than most available alternatives. This performance principle also applies to the application of thermally conductive materials.
The appearance of the product meets various needs
As technology continues to evolve, glass fibers and composites are gel-coated in molds with special treatments in a wide variety of colors and textures to achieve a variety of looks and colors required by customers. Fiberglass and composite parts are available in flat, semi-gloss or high gloss. So as to meet the appearance requirements of thermal silicone pads and various thermally conductive materials.
Many times, in the process of supplying products, we always receive some special requirements from customers. While ensuring thermal conductivity, we also require adding reinforcing materials, whether it is glass fiber, single-sided adhesive, double-sided adhesive, The requirements of 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 the application requirements of customers. This is not also produced as a professional thermal conductive material. Does the manufacturer really need to do it?
