Recently, Canlon PVC-18P polyvinyl chloride waterproof membrane and Canlon TPO-18P thermoplastic polyolefin waterproof membrane, both products of Jiangsu Canlon Building Materials Co., Ltd., have passed the authoritative testing of China Building Materials Testing & Certification Group Suzhou Co., Ltd. They have all met the requirements of GB8624-2025 "Classification of Burning Performance of Building Materials and Products" for roofing covering materials and products, specifically Class B1 (flame-retardant) burning performance, successfully obtaining national-level testing and certification. This demonstrates their robust fire-resistant capabilities in fulfilling the Ministry of Housing and Urban-Rural Development's "Good House" construction guidelines.
In the field of building waterproofing, a profound conceptual transformation is reshaping the design and construction logic of roofing systems. Traditional "built-up roofing" adopts a "heavy" approach of stacking multiple layers of asphalt and felt, attempting to achieve waterproofing through material accumulation. In contrast, the "single-ply roofing system," represented by TPO and PVC membranes, achieves a fundamental shift from "quantity" to "quality" and from "layering" to "integration" with its lightweight yet multifunctional single-layer membrane. Single-ply roofing refers to a roofing system that uses a single layer of flexible waterproofing membrane as the primary waterproofing component, working in conjunction with insulation layers, vapor retarders, and other components. Introduced to China in 1999, after more than two decades of development, it has become widely adopted in industrial plants, stadiums, airports, large commercial buildings, and other venues, emerging as a mai
Whether it's waterproofing and renovation of a residential roof or waterproofing construction of concrete roofs for shops and factories, the PVC mechanical fixing solution for concrete roofs has become a highly popular choice in recent years due to its advantages of high efficiency, strong stability, and wide adaptability among many waterproofing solutions. What is mechanical fastening? How does it differ from traditional adhesive methods? Why is it suitable for concrete roofs? Can it be used on my own roof? Canlon will explain it all for you today.
Nongfu Spring's Dujiangyan Production Base is a comprehensive production base invested and constructed by Nongfu Spring in Dujiangyan City, Chengdu, Sichuan Province. Located in the Qingcheng Mountain Tourism Equipment Industrial Functional Zone, it covers an area of 446.7 acres and has a total investment of 1.35 billion yuan. The base adopts automated and digital production technologies and integrates industrial tourism functions, mainly producing drinking natural water and aseptic beverages. This project is a core project of the "Tianfu Good Water" industrial cluster in Dujiangyan City. As a high-quality case of Canlon, it was honored to be selected as the Jinyu Award — Gold Award for Metal Enclosure System Engineering in 2025.
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."
Recently, the Hainan Provincial Department of Housing and Urban-Rural Development officially released the "Hainan Provincial Technical Standard for Metal Roofing" (DBJ 46-075-2025). This standard, tailored to Hainan's unique geographical characteristics of high temperature, high humidity, high salinity, high radiation, heavy rainfall, and frequent typhoons, establishes comprehensive technical specifications covering the entire process from material selection, design and construction, quality acceptance to maintenance and repair. It will officially take effect on April 1, 2026. As a participating unit in the standard's drafting, Canlon was deeply involved in the standard's development, providing crucial support for its practicality and implementation through its core products such as polymer waterproof membranes and metal composite panels, as well as its engineering experience.
At the 2026 Qidu Town Work Style and Efficiency and Business Environment Optimization Conference held on March 2, the Qidu Town People's Government commended advanced enterprises in economic work in 2025. It hoped that entrepreneurs and units would take advanced models as examples, strive to be role models, work hard, continuously improve their core competitiveness, and create more brilliant and proud new achievements.
In the history of modern construction, persistent leakage, akin to a "water curtain cave," has long plagued the industry and end-users. The limitations of traditional waterproofing materials in terms of durability, environmental friendliness, and construction convenience have struggled to meet the higher demands of contemporary buildings for long-term safety, energy efficiency, and sustainability. Today, polymer waterproofing membranes, represented by PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), and HDPE (High-Density Polyethylene), are leading a technological revolution with their superior performance, becoming the preferred solution for large public buildings, industrial plants, transportation hubs, and green roofs.
Polymer waterproofing membranes play a critical role in modern construction, with Thermoplastic Polyolefins (TPO) and Polyvinyl Chloride (PVC) being two widely used primary materials. Their long-term performance, particularly weatherability and durability, directly determines the reliability and service life of building envelopes. This article will delve into the impact of environmental factors on the molecular structures of these two materials from a materials science perspective and explore the underlying aging mechanisms and their respective application scenarios.
