China SABIC ULTEM SILTEM-STM1500 Manufacturer, Supplier, Factory

SABIC polymers are high-performance plastics produced by SABIC, a global diversified chemicals company headquartered in Riyadh, Saudi Arabia. These polymers are integral to various industries, including automotive, healthcare, electronics, and packaging, due to their exceptional properties and versatility.

The PC/ABS alloy combines the high strength and heat resistance (110°C) of PC with the easy processability of ABS, widely used in automotive (dashboards, door handles), 3C electronics (laptop casings), communications (5G base station covers), and home appliances. It features UV resistance, flame retardancy (V-0 rating), and dimensional stability. Defects like silver streaks and warping are addressed through drying (120°C ×4h), mold temperature optimization, flow promoters, and structural design. Nano-enhanced (thermal conductivity 1.2 W/m·K) and bio-based modifications (40% carbon reduction) are expanding its applications in new energy and medical fields.

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.

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.
