In modern firefighting equipment, the choice of material for helmet visors is of utmost importance. Today, we will delve into two high-performance plastics—PPSU and PSU—and their outstanding performance in firefighter helmet visors and other high-end applications.

The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

​Recently, domestic polymer materials leader VISA officially released its innovative application solutions for polyphenylene oxide (PPO)-based materials in the automotive sector. This series of products, based on high-performance blends of PPE and PS, has developed over 20 differentiated grades tailored to the needs of new energy vehicles and traditional automotive components, demonstrating breakthrough progress in lightweighting, safety, and functional integration.

Special engineering plastics, as the pinnacle of the field of polymer materials, are a class of high-end engineering plastics with characteristics such as high temperature resistance (long-term operating temperature > 150°C), high strength, and corrosion resistance. Their core value lies in achieving metal substitution through unique molecular structure design, playing an irreplaceable role in strategic industries such as aerospace, new energy, and electronic information. Currently, the global industry is undergoing a structural upgrade from general-purpose plastics to high-performance materials. Special engineering plastics, with their revolutionary advantage of "replacing steel with plastics," have become a key material for the transformation and upgrading of advanced manufacturing.

Here is the English translation of the provided text, maintaining the structure, terminology, and nuances: From the Industrial Revolution to the Rise of the Polymer Industry Since DuPont invented nylon and coined the term "NYLON," launched the ZYTEL brand in 1954, and up to the present day, the modified applications of nylon and high-temperature nylon (HTN) in sectors like automotive, electronics, consumer goods, military, and aerospace have spanned over 70 years. However, the foundational equipment for modifying engineering plastics is certainly not something a 300,000 RMB extruder can handle.

As a global leader in the chemical industry, Saudi Basic Industries Corporation has launched its new LNP™ ELCRES™ CXL polycarbonate (PC) copolymer resins, which possess outstanding chemical resistance. These special materials are highly suitable for helping customers in the mobility, electronics, industry and infrastructure markets deal with environmental stress cracking and premature failure that may be caused by increased exposure to corrosive chemicals. Besides having higher chemical resistance than existing materials, the LNP ELCRES CXL copolymer resins can also enhance the durability and reliability of components with excellent low-temperature impact resistance and weatherability.
