Plastic DURACON POM (polyoxide), due to its outstanding mechanical properties and processing performance, has become an important material for many high-precision and wear-resistant parts, and its application fields are very wide.

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.

High-Performance PPS (Polyphenylene Sulfide) Film with Broad Application Prospects PPS (Polyphenylene Sulfide) is a high-performance specialty engineering plastic, classified as a high molecular weight crystalline polymer with a density of 1.35 g/cm³. It features a linear molecular structure formed by alternating benzene rings and sulfur atoms. The combination of rigid benzene rings and flexible thioether linkages endows PPS with outstanding properties, including excellent heat resistance, flame retardancy, chemical corrosion resistance, mechanical strength, and dimensional stability.

PPA (Polyphthalamide), a high-performance specialty engineering plastic known as the "special steel" of plastics, is quietly reshaping manufacturing. With exceptional heat resistance (long-term use at 150-180°C), high strength/rigidity, and excellent chemical resistance, PPA is an ideal material replacing traditional plastics and metals. It plays a key role in automotive electrification (e.g., charging components), electronics miniaturization (e.g., 5G antennas), and industrial extreme environments, driving industries towards lighter weight and higher performance.

Recent volatility in crude oil prices has driven up the cost of plastic raw materials. Global chemical giants including BASF and SABIC have announced multiple rounds of price increases, keeping engineering plastic prices firm. In this environment, the plastics supply chain faces dual challenges of rising costs and supply uncertainty. Our company is an integrated enterprise combining import trading of engineering plastic raw materials, application development, product design, and molding manufacturing. As a long-term partner of internationally renowned brands such as BASF and SABIC, we leverage our global sourcing capabilities and technical expertise to provide customers with stable, reliable raw material supplies and professional solutions. We are committed to helping our global partners navigate market changes with efficiency and resilience.

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.
