China BASF Ultramid A3EG7BK00564 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.

This article systematically expounds on the development process of China's special engineering plastics industry from the germination stage to the maturity stage, analyzes the current industry situation at the critical stage of transition, covering influencing factors such as policies, technologies, and the market. It also introduces the upstream, midstream, and downstream situations of the industry chain, including the supply of raw materials, production, and the demand in application fields. At the same time, it explores the opportunities and challenges of green development that the industry is facing.

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.

Traditional perceptions are being transformed as industrial-grade 3D printing evolves beyond prototyping into direct digital manufacturing. In this revolution, Polyetheretherketone (PEEK) and Polyetherimide (PEI/ULTEM) are fundamentally reshaping the industrial landscape. PEEK stands out for its exceptional high-temperature resistance, outstanding mechanical strength, and excellent biocompatibility, making it the premium choice for aerospace components and customized medical implants. PEI, known for its inherent high strength and superior flame retardancy, has become the essential material for aircraft interiors and critical electronic components. VISA delivers expert analysis of how these advanced materials push the boundaries of design and manufacturing. We provide powerful digital manufacturing solutions for high-end industries, leading the new wave of future manufacturing innovation.

In the engineering plastics industry, color difference control has moved far beyond visual judgment. The L, a, b values form the internationally recognized three-dimensional coordinate system for color, representing lightness, red-green hue, and yellow-blue hue respectively. Understanding these three numbers is the key to correctly interpreting colorimeter reports and pinpointing the root cause of color deviation—whether it comes from material batch variation, drying process instability, or injection molding parameter drift.
