China SABIC ULTEM 3452 Manufacturer, Supplier, Factory

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.

Facing rising material costs, manufacturers can significantly cut expenses by switching from traditional painted or two-shot molded automotive B/C pillar trims to high-gloss PC/ASA/PMMA—a paint-free, single-shot solution. This eliminates painting defects, reduces equipment needs, and saves 101 RMB per vehicle (20M RMB/year at scale), while improving heat resistance and design flexibility. Success depends on material-performance alignment, process optimization, and supplier collaboration. Strategic material substitution, not just cheaper alternatives, drives sustainable cost reduction.

When the project is advancing, it is necessary to promptly respond to the technical issues raised by the clients and the troublesome matters they report, and help them solve the actual problems. After the products are sent out, it is necessary to visit customers regularly to ask about how they are doing with the products, listen to their thoughts and suggestions, and then continuously improve the products and services.

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.

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.
