China SABIC ULTEM 2300N Manufacturer, Supplier, Factory

​When Unitree H1 from YUSUR Technology twisted in Yangko dance on Spring Festival Gala’s grand stage, Tesla’s Optimus Gen2 deftly assembled circuit boards, and Figure 01 flawlessly crafted latte art, the global tech community witnessed an unprecedented revolution. Let’s explore the polymer material innovations behind seven humanoid robots:

First plastic gas tank for commercial vehicles made of BASF's high-performance Ultramid® polyamide, which weighs up to 20 percent less than an aluminum alternative

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.

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.

Injection molding often encounters burn marks, a critical defect that severely impacts product appearance and quality. This article deeply analyzes the root causes of burn marks and proposes systematic countermeasures.

The J10C achieves a transformative advancement in China’s aviation sector through five core material innovations: carbon fiber composites for weight reduction, stealth coatings for RCS suppression, ultrahightemperature ceramics for extreme environments, titanium/aluminum alloys for structural reinforcement, and advanced resinbased materials for electronic warfare. These breakthroughs propel China’s aviation industry from "follower" to "leader," laying the technical foundation for subsequent models like the J20 and J35.
