From September 21 to 24, 2026, THE 12TH ALL CHINA - INTERNATIONAL WIRE & CABLE INDUSTRY TRADE FAIR (Wire China 2026) will be held at the Shanghai New International Expo Center in China. YinSu Flame Retardant will be showcasing its five core product lines at Booth E7G35 in Hall E7，Whether you’re interested in power cables, control cables, communication cables, or specialty wires, we have products of various grades and applications to discuss. We welcome both new and existing customers to scan the QR code to register and visit our booth for a face-to-face discussion.
From September 15 to 17, 2026, at the Shanghai New International Expo Center, The 29th Adhesives and Sealants Expo (ASE CHINA 2026) is set to kick off. Also taking place at the same venue and during the same period are the 24th China International Rubber Technology Exhibition and the 23rd China International Chemical Industry Exhibition. Together, these three exhibitions will form “China Petrochemical Industry Week,” which is expected to attract more than 100,000 professional visitors from both China and abroad.
A Comprehensive Analysis of PVC Flame Retardant Types, Synergistic Mechanisms, and the UL 94 Flame Retardancy Rating Standard. Due to the presence of plasticizers, the LOI of flexible PVC decreases significantly; therefore, highly effective flame retardancy must be achieved through synergistic blending of chlorinated paraffin, red phosphorus, antimony trioxide, and other compounds. This article provides a detailed explanation of the mechanisms of action for halogen-based, phosphorus-based, nitrogen-based, and inorganic flame retardants, covering classic case studies in applications such as PVC cable compounds, pipes, and profiles, and serves as a technical reference for formulation engineers engaged in PVC flame retardant modification.
The current downturn in the melamine market provides a short-term cost advantage for downstream flame retardant manufacturers, but concurrent weakness on the demand side may partially offset this benefit. Companies are advised to take advantage of the current raw material price window to optimize their procurement strategies, while closely monitoring the pace of demand recovery in end-user industries such as building materials and cables.
Flame-retardant PVC intended for export must comply with various regulations, including the EU’s REACH (SVHC screening + CPR fire safety requirements), California Proposition 65 (limit of 25 ppm per substance), and Southeast Asian chemical registration requirements. Since copper wires come into contact with cables, whereas pipes do not, the paths to compliance differ significantly. YinSu Flame Retardant offers export compliance solutions tailored to specific product types and markets, thereby reducing the risk associated with formulation adjustments.
PVC cable compounds still account for 38.7% of the global market (approximately $7.07 billion), while LSZH materials are 30–50% more expensive and require equipment upgrades. GB/T 19666 specifies that low-smoke, halogen-free cables must have a smoke density and light transmittance of ≥60%, a pH of ≥4.3, and a conductivity of ≤10 µs/mm. For requirements related to smoke density and corrosivity, upgrading to flame-retardant PVC (replacing antimony trioxide with red phosphorus, resulting in a cost increase of only 8–12%) is a more rational choice.
