China SABIC NORYL N225X Manufacturer, Supplier, Factory

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.

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.

In September 2025, the Shanghai Visa Plastics team embarked on a four-day trip to western Sichuan. They tempered the team spirit amid the mountains and rivers of Jiuzhaigou and Huanglong, and gained innovative inspiration from the ancient Shu civilization at Sanxingdui. They supported each other during the plateau hike, practicing the corporate belief of "win-win cooperation"; facing the thousand-year-old cultural relics, the craftsmanship spirit and technological innovation resonated across time. This was not only an enhancement of team cohesion but also an in-depth awakening of professional craftsmanship. The Visa people will carry this harvest and work together to open a new chapter in plastic technology with greater enthusiasm and more solid collaboration.

SABIC DU242 PEI: The Perfect Balance of High Flow and Low-Temperature Toughness SABIC ULTEM™ DU242 is a polyetherimide (PEI) blend engineered for complex parts and demanding environments. Its key strengths lie in the unique combination of high flowability (for easy processing of thin-wall, intricate geometries) and enhanced low-temperature impact resistance, while maintaining a Heat Deflection Temperature of 160°C and UL94 V-0 flame rating. As a comprehensive enterprise integrating science, industry, and trade, we not only supply this high-performance material but also leverage our technical team to provide full-chain support—from product design and material selection to molding process optimization—empowering your innovations in automotive, electronics, industrial, and other sectors.

SABIC ULTEM™ 2310 is a 30% glass fiber-reinforced polyetherimide (PEI) resin that combines excellent flowability, ultra-high strength (tensile strength up to 169 MPa), and inherent flame retardancy (UL94 V0 & 5VA). It features a heat deflection temperature of 210–220°C, continuous use from -160°C to 180°C, and very low mold shrinkage (0.2%–0.6%). The medical grade (HU2310) offers ISO 10993 or USP Class VI biocompatibility and withstands multiple sterilization methods. Ideal for medical devices, high-temperature connectors, semiconductor tooling, and aerospace/automotive components, ULTEM™ 2310 is the all round ace for demanding injection molding applications.

BASF Ultramid® A 50H1 is a high performance PA66 grade based on a halogen free and phosphorus free flame retardant system. It achieves V 0 flammability rating while retaining the excellent mechanical strength and processability typical of polyamides. With a tensile modulus of 3800 MPa and good low temperature toughness – remaining robust even at –30°C – it resists brittle failure in harsh environments.
