Since 2025, multiple countries have introduced a wave of trade restrictions, with the plastics industry bearing the brunt. Thailand announced a ban on plastic waste imports, Japan fully prohibited products containing perfluorooctanoic acid (PFOA), the EU expanded its 16th round of sanctions against Russia to include primary aluminum imports, and the Philippines proposed a nickel ore export ban. These measures not only disrupt raw material supplies but also reshape the global plastics trade.

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.

From Feb 9-10, our team escaped to Chongming Island for a spring retreat. Day 1 featured our year-end review meeting, followed by team games and a warm dinner. Day 2 brought creative crafting sessions and collaborative challenges. Though brief, these two days refreshed us amidst nature and strengthened our bonds. We return energized and united—ready to embrace the exciting journey of 2026 together!

PFAS, known as “forever chemicals,” are a large group of fluorinated substances with extremely stable carbon-fluorine bonds that resist degradation in the environment and pose health risks. In engineering plastics, fluoropolymers such as PTFE, PFA, and PVDF are used either as base materials or processing aids to provide heat resistance, low friction, and non-stick properties. Due to tightening regulations by the EU, U.S., and China, customers now demand PFAS test reports to verify compliance. This requirement helps avoid customs detention, meet brand owners’ sustainability mandates, and prevent costly lawsuits. Without a valid report, products risk being excluded from supply chains. The industry is rapidly moving toward PFAS-free alternatives. A certified test report has become a mandatory pass for global trade in engineering plastics.

Tesla’s Optimus production line is nearing completion and will start production in 2027, driving PEEK/PPS demand as humanoid robots scale. The Terafab chip project adds semiconductor plastics demand. High-end grades still rely on imports, so traders should prepare categories, supply chains, and technical services.
