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.
Recently, the Jiangsu Provincial People's Government awarded the Jiangsu Provincial Science and Technology Award Certificate. The project "Research and Industrialization of Nuclear Power Grade High-Reliability Self-Healing Special MBP Impermeable Composite Material", completed by Canlon and Southeast University, won the second prize of Jiangsu Provincial Science and Technology Progress Award.
On March 14, 2026, the 2026 Annual Partner Conference of Canlon, themed "Starting a New Journey with Intelligence and Creating the Future", was successfully held in the beautiful Dianchi Lake in Kunming. Hundreds of partners who have accompanied Canlon in its growth and struggle over the years gathered together to build a better future. 2026 marks the start of the nation's 15th Five-Year Plan. Canlon closely follows the nation's key goal of "accelerating high-level technological self-reliance," resonating with national strategy. At the beginning of the conference, Canlon’s employees and partners stood and sang the national anthem, dedicating the company's high-quality development to the motherland.
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.
In the field of building waterproofing, the development history of modified bitumen membranes is a history of technological evolution in construction methods, from "fire" to "cold," and from "complex" to "convenient." From the early "fire-baking" operations of traditional hot-melt materials such as SBS and APP, to today's "cold construction" processes of new bitumen-based materials such as self-adhesive and wet-laying, each technological iteration has profoundly responded to the industry's higher pursuit of safety, environmental protection, and construction efficiency. This article will systematically trace this technological evolution and showcase the innovative achievements of industry leader Canlon in this field.
The bathroom is the area in the home with the most frequent water usage and also the most concentrated source of leaks. Statistics show that the leakage rate of newly built residential buildings in China exceeds 20% within three years. However, bathroom leaks are one of the most troublesome problems in home repairs—invisible and intangible, yet capable of causing neighborhood disputes, structural damage, and even safety hazards. The traditional method of "breaking through bricks to find the leak" is not only costly but also prone to misjudging the location. Therefore, accurately and efficiently locating the leak has become a core technology in the field of waterproofing and repair.
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.
