Recently, a meeting was successfully held in Suzhou to revise three national standards: "Thermoplastic Polyolefin (TPO) Waterproof Membrane," "Polyvinyl Chloride (PVC) Waterproof Membrane," and "Chlorinated Polyethylene Waterproof Membrane," which are under the jurisdiction of the National Technical Committee on Standardization of Lightweight and Decorative Building Materials (SAC/TC 195) and the Subcommittee on Waterproofing Materials for Buildings (TC195/SC1), and to organize the revision of the industry standard "Waterborne Polymer Modified Bitumen Waterproof Coating."

On March 27, 2026, the 12th Metal Enclosure Systems Industry Conference was held in Beijing. It brought together nearly 400 representatives from over 110 companies in the national metal enclosure systems industry. Chen Jie, Chairman of the Enclosure System Branch of the China Steel Structure Association, announced the winners of the 2025 "Technological Innovation Award" of the China Steel Structure Association. Among them, the "Polymer Membrane Metal Composite Sandwich Panel" project completed by Canlon won this prestigious award for its industry-leading innovation and practicality.

On March 11, 2026, the Ministry of Industry and Information Technology issued an announcement officially approving the publication of 453 industry standards, including "JC/T 2962-2026 Water Intake Quota for Building Waterproofing Materials" and "JC/T 2963-2026 Water-Saving Enterprises' Waterproofing Materials Industry Standards," providing important technical support for the green, low-carbon, water-saving, and efficient development of the building materials industry. Jiangsu Canlon Building Materials Co., Ltd., as a core participating unit, deeply participated in the drafting of both standards , contributing significantly to the standardization of water use and the systematization of water conservation in the industry with its technical strength and practical experience.

In the realm of single-ply roofing systems, TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) stand as two undisputed "titans." Both belong to the thermoplastic membrane family, both utilize hot-air welding technology, and both can form monolithic waterproofing layers. However, these "twins" have fundamental differences in material chemistry, performance characteristics, and application scenarios. Should you choose TPO, known for its cost-effectiveness and environmental friendliness, or PVC, recognized for its robust performance and chemical resistance? This article provides a comprehensive multi-dimensional comparison covering weatherability, environmental friendliness, fire performance, cost, and construction friendliness. Instead of declaring an absolute winner, we aim to help you find the true "champion" for your specific project.
