Japan has developed liquid crystal polymer thermoplastic resin with significantly improved thermal conductivity

Kaneka company in Japan has developed liquid crystal polymer thermoplastic resin with extremely high thermal conductivity, and has begun to supply samples to users. Even if only a small amount of inorganic filling materials are added to the resin material, it can achieve high thermal conductivity and can be used as heat dissipation materials in the fields of automobiles, information terminals and lighting to the market

Kaneka company of Japan has developed a liquid crystal polymer thermoplastic resin with high thermal conductivity, and has begun to supply samples to households with a moderate increase in 2014 U.S. plastic material transactions. Even if only a small amount of inorganic filling materials are added to the resin material, it can also achieve high thermal conductivity, and can be introduced to the market as a heat dissipation material in the fields of automobile, information terminal, lighting and so on, which is not simply the reduction of charge items and costs

heat dissipation materials using polyamide, polyester and other commonly thermoplastic resins need to add a large number of conductive boron nitride and other expensive inorganic filling materials with excellent thermal conductivity due to the low thermal conductivity of the resin itself. However, this method is not only costly, but also has problems such as increasing the proportion of materials and decreasing the workability of molding

the newly developed liquid crystal polymer resin improves the thermal conductivity of the resin itself by controlling the arrangement of polymers. Therefore, even if only a small amount of filling material is added, it still has high thermal conductivity. Under the condition of maintaining the same thermal conductivity as the previous materials, the addition amount of filling materials only needs to account for about 20% of the volume

the heat dissipation material using this resin has the following main properties: the thermal conductivity in the in-plane direction is 14w/mk, the specific gravity is 1.8 ~ 2.1, and the flame retardancy is equivalent to V-0. Because of its excellent fluidity, ordinary injection molding machines can be used to form in China's plastic machinery market. In addition, more than 50% of the raw materials come from plants, so the environmental protection is also very prominent

in terms of the price of heat dissipation materials made of new materials, Kaneka believes that due to the reduction of filling materials, it can be cheaper than previous heat dissipation materials. The company will step up efforts to bring its products to the market and strive to achieve sales of about 2billion yen in five years
