China SABIC ULTEM MD133 Manufacturer, Supplier, Factory

Engineering plastics are better than ordinary plastics in thermal stability, mechanical properties and chemical resistance, and are widely used in automotive, electronic and electrical, aerospace and other fields. Ordinary plastics dominate the field of daily necessities and packaging materials because of their low cost. Both have their own advantages and work together to promote industrial development.

Engineering plastics with exceptional heat resistance maintain robust mechanical properties in high-temperature environments, making them indispensable for demanding applications. Beyond widely known high-temperature nylons, five other categories of heat-resistant engineering plastics play critical roles across industries.

This article delves into the complete transformation process of engineering plastic pellets from raw material to precision parts. It systematically introduces the three fundamental processes of injection molding, extrusion, and blow molding, extending to specialized techniques like thermoforming and rotational molding.

Engineering plastic modification is like "turning stone into gold," leveraging three core technologies—additives, fillers, and flame retardants—to dramatically enhance resin performance. Additives enable toughening, compatibilization, and anti-aging with minimal dosage; fillers like glass fibers, PTFE for lubrication, or minerals balance rigidity, toughness, and cost; flame retardants provide self-extinguishing safety. As an integrated enterprise specializing in trade, application development, and molding, we deliver tailored engineering plastic solutions through precision modification formulations.

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.

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.
