New plastic additives

The quality of plastics is light, bright, and inexpensive, and it is popular with consumers. However, its biggest drawback is that it is susceptible to fading and decomposition due to the influence of ultraviolet rays in sunlight. For this reason, foreign countries are vigorously developing new additives that can improve the ultraviolet radiation resistance, oxidation resistance (decomposition) and high color fastness of plastic products. A series of new types of HALS (hindered amine light stabilizers) class of new plastic additives have been developed. According to reports, plastics with added HALS additives (such as PVC plastic) are suitable for making plastic trash cans, packaging bags, containers, flower pots, artificial stadium tracks and products to increase the proportion of non-connector products.
The second largest manufacturer of Type 1 products in Japan, Sumitomo Chemical Corporation, expanded its net liquid crystal resin production capacity to 2,000 tons per year in 1984 and developed New Products for connectors.
Nippin (Japan), another manufacturer of Type 1 products, will ensure the company's high-yield system through the development of its LCP business. Toray Industrial Co., Ltd. entered the LCP market later, but he quickly increased the share of LCP used for high-level connectors. His products include molding grade and heat-resistant grade H.
DIC (Dainippon Ink and Chemicals Corporation) expanded its blending business of competitive resins such as PBT and PPS. In 1998, he changed the LCP from Sumitomo Chemical Co. to LCP of Dupont Co., Ltd. Compatibility, excellent moldability and high temperature resistance. Since the spring of 1999, the company has achieved very good business results, and sales of LCP compounded ingredients are expected to reach 500 tons.
The only LCP-fiber production company in the world, Kurarav, plans to open up new uses for marine materials and electronic materials in fiscal year 1999, and strive to increase sales by 10%.
