China SABIC CYCOLOY C2950 Manufacturer, Supplier, Factory

NORYL is a NORYL resin owned by SABIC. NORYL was previously a trademark of GE and is the symbol of polyphenylene ether (PPO) resins in the group. It is one of the world's five major general engineering plastics. They combine the high heat resistance of polyphenylene ether resins at a low cost, good electrical properties, excellent hydrolytic stability, and the ability to be packaged with halogen-free flame retardants, with excellent dimensional stability, good processability, and low specific gravity. NORYL resins have good mechanical and chemical properties and may be suitable for a wide variety of applications.

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.

This article systematically expounds on the development process of China's special engineering plastics industry from the germination stage to the maturity stage, analyzes the current industry situation at the critical stage of transition, covering influencing factors such as policies, technologies, and the market. It also introduces the upstream, midstream, and downstream situations of the industry chain, including the supply of raw materials, production, and the demand in application fields. At the same time, it explores the opportunities and challenges of green development that the industry is facing.

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.

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.

High-Performance PPS (Polyphenylene Sulfide) Film with Broad Application Prospects PPS (Polyphenylene Sulfide) is a high-performance specialty engineering plastic, classified as a high molecular weight crystalline polymer with a density of 1.35 g/cm³. It features a linear molecular structure formed by alternating benzene rings and sulfur atoms. The combination of rigid benzene rings and flexible thioether linkages endows PPS with outstanding properties, including excellent heat resistance, flame retardancy, chemical corrosion resistance, mechanical strength, and dimensional stability.
