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 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.

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.

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.
