The article provides information on China's styrene capacity and its distribution in different regions. China's styrene capacity accounts for a significant portion of the global capacity, and its proportion is expected to increase as its capacity continues to grow. The article also discusses the consumption analysis of styrene, with polystyrene (PS) being the largest downstream consumer, followed by expandable polystyrene (EPS) and acrylonitrile butadiene styrene copolymers (ABS).

The article focuses on Polynt's new flame-retardant unsaturated polyester resin, Polynt A 6104 A, designed for high flame retardancy in molding applications, including its use in creating parts for the transportation industry and the resin's performance in flame and smoke tests.

The article presents selection guide to resin matrices for composites. Topics discussed include applications of polymer, ceramic, metal and carbon matrices, insight on thermosets, like unsaturated polyester resins, which are polymers most widely used in composites, and reason catalysts are added to the resin prior to molding.

The article reports that the 13th Five-Year Plan, Chinese coal-to-ethylene glycol (CTEG) has developed for modern coal chemical industry faces much emission reduction as the target of carbon peaking and carbon neutrality forward in 2021. It mentions that the import of polyester has impacted ethylene glycol market, making coal to-ethylene glycol trapped into a dilemma of supply and demand.

The article traces the history of polymeric materials. Topics discussed include the discovery of the chemistry that allows for the process of crosslinking using a material like styrene monomer or vinyl acetate to create a thermosetting material, the introduction of the vinyl monomer styrene as a crosslinking agent and the commercialization of styrene at the start of World War II.

The article reports that while the majority of thermoplastics have a stability of years, certain materials, especially thermosetting ones, may have a limited shelf life due to the presence of catalysts and chemical activity, requiring careful storage considerations and, in some cases, refrigeration to maintain integrity and processability. It emphasizes the importance of objective testing to assess material integrity over time, challenging vague beliefs about polymer shelf life.

The article focuses on resin matrices for composites, providing a guide to the selection of matrices such as polymers, ceramics, metals, and carbon, with a detailed examination of thermoset polymers, particularly unsaturated polyester resins, discussing their properties, applications, and modifications, and offering insights into the ongoing research and development in the field of bio-resins.

The article offers information on the annealing process. Topics discussed include annealing which can relieve stresses in amorphous materials and increase crystallinity in semi-crystalline resins; mentions the purpose for annealing in Semi-crystalline polymers are used because of the mechanical and thermal attributes that arise from their crystallinity; and the rationale for annealing, and the effect that it has on the material, will depend greatly upon the polymer being annealed.

The article focuses on the need to improve the application and research and development (R&) capability of China for dicyclopentadiene (DCPD). It states that China used DCPD to develop petroleum resins, unsaturated polyester resins, and the third monomer. It mentions three suggestions for future development of DCPD such as the advantage use of ethylene plants, DCPD product with different levels of purity, and strengthen the use and development of DCPD to produce chemical products.
