Driven by the rapid development of the electronics and information industry, high-thermal-conductivity plastics are gradually replacing traditional metal heat dissipation materials, gaining widespread adoption in critical fields such as LED lighting, semiconductor packaging, electronics, and automotive electronics.

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 systematically decodes nine key performance indicators of engineering plastics, covering basic properties, mechanical strength, surface and electrical characteristics, temperature/weather resistance, chemical stability, and cost economics. By comparing the performance differences and application scenarios of various plastic materials, it reveals the scientific principles and trade-off wisdom in material selection. The text emphasizes that in this era where materials define products, a deep understanding of plastic properties is fundamental for achieving product innovation and enhancing performance and value. It also looks forward to development trends toward high performance, functionality, and environmental sustainability.

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.

PES is a high-performance specialty engineering plastic. Thanks to its unique molecular structure, it maintains excellent mechanical strength and dimensional stability even under long-term high-temperature environments (above 180°C). It also offers transparency, hydrolysis resistance, flame retardancy, and is BPA-free. Widely used in medical devices (e.g., reusable sterilizable instruments), electronics (high-temperature connectors), and automotive components, PES is a critical material for high-end industrial and technological products.
