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.

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.

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.

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.

With the popularity of electric vehicles around the world, the technical requirements for key components are also increasing.

BASF, a global leader in the chemical industry, recently announced the launch of an innovative polyphthalamide (PPA) product, Ultramid® Advanced N2U40G5. This product is specifically developed to meet the stringent technical requirements of the new - generation USB Type - C connectors. The material is now locally produced in China and can be supplied to the global market.
