China SABIC ULTEM 1110 Manufacturer, Supplier, Factory

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.

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.

Polyphenylene Sulfide (PPS), hailed as "plastic gold," is a high-performance engineering plastic known for its exceptional heat and chemical resistance, inherent flame retardancy, and dimensional stability. It is widely used in automotive lightweighting/electric components, Precise electronics, and harsh industrial environments like chemical processing, providing key solutions beyond traditional materials. Choosing PPS means selecting superior reliability, longevity, and a competitive edge.

PES is a high-performance specialty engineering plastic. Thanks to its unique molecular structure, it maintains excellent mechanical strength and dimensional stability even under long-term high-temperature environments (above 180°C). It also offers transparency, hydrolysis resistance, flame retardancy, and is BPA-free. Widely used in medical devices (e.g., reusable sterilizable instruments), electronics (high-temperature connectors), and automotive components, PES is a critical material for high-end industrial and technological products.

SABIC LEXAN™ 731S-701S is a high-flow, high-impact injection molding grade black polycarbonate (PC) material. It is opaque, with a notched impact strength of 80–90 kJ/m² and a heat deflection temperature of 130–135°C. Its melt flow index is more than 50% higher than that of standard PC, making it ideal for rapid molding of thin-wall, long-flow-path, and complex molds. Optimized mold release design reduces drag marks and improves yield. This black material delivers a high-gloss, light-blocking surface. Some batches offer V-2 flame retardancy and UV stability. It is widely used in electronic housings, automotive interior light-blocking parts, medical light-avoidance components, and safety goggle frames. We offer a stable supply of genuine black material and full technical support from material selection to trial molding.

On May 15-16, the HUNTER team traveled to Anji for a two-day, one-night team building retreat.As we drove back to Shanghai, we carried the mountain breeze in our luggage and the drive back to our desks. Because the best team waits for you uphill, stays with you downhill, and trusts you in Werewolf. Now, we continue – shoulder to shoulder, giving it our all.
