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.

Automotive engineering plastics are driving comprehensive technological upgrades and green transformations across body structures, exterior systems, powertrain-chassis, and interiors through innovations in lightweighting, high performance, and sustainability.

With the increasing demand for high-frequency and high-speed transmission, PEI has reduced its dielectric constant to below 3.0 (at 1 GHz) through molecular structure optimization (such as the introduction of fluorinated groups), making it a core material for 5G millimeter-wave connectors.

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.

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.

Basic Concept of CLTE The Coefficient of Linear Thermal Expansion (CLTE) is used to characterize the degree of expansion of a material as temperature rises and to assess its risk of cracking under thermal stress. Understanding the relative expansion/contraction properties between different materials in contact is crucial for successful applications.
