In recent years, China's construction waterproofing industry has witnessed a transformative shift from traditional asphalt-based materials to advanced polymer materials. Three representative polymer waterproofing membranes—PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), and HDPE (High-Density Polyethylene)—are becoming the preferred solution for modern construction waterproofing due to their exceptional performance. This article provides an in-depth analysis of the characteristics and applications of these three materials and highlights the innovative achievements of industry leader Canlon in the polymer sector.
On January 27, 2026, the signing ceremony of the annual strategic agreement between Canlon and Central Asia Canlon (CCA) was successfully held in the Polymer Industrial Park, marking the official start of a new cycle of cooperation between the two parties and further enhancing Canlon's brand influence in Central Asia. In the future, Canlon Group will continue to uphold the spirit of innovation, cultivate the Central Asian market, and make the brand influence of "International Canlon" stronger and stronger, contributing more "Canlon power" to the global waterproofing industry!
When you stand in a building materials market, faced with the classifications of polyurethane waterproof coatings such as "solvent-based" and "solvent-free," "water-based" and "oil-based," do you feel like you're making an uncertain choice? Behind this lies an invisible battle between environmental protection, health, and construction safety. Today, we'll help you thoroughly understand this crucial choice that determines the quality of your bathroom waterproofing!
Today, Canlon is continuously empowering emerging industrial clusters to meet their diverse and systematic needs for building quality through its diversified and customized system solutions, including single-ply roofing systems, underground engineering, and photovoltaic roofing. In 2025, Canlon assisted in the construction of multiple projects in the Hainan Free Trade Zone and the construction of a billion-yuan-level fiberglass production base in Zhejiang. It also provided system solutions for the first nuclear power unit of the "15th Five-Year Plan" and the world's first dual-reactor coupled nuclear energy project—the Jiangsu Xuwei Nuclear Heating and Power Plant—providing a vivid example for the construction of emerging urban industrial clusters.
Recently, Canlon, based on its comprehensive strength and trustworthy business performance, was awarded the highest credit rating—AAA—by the China Building Waterproofing Association after rigorous review. The AAA credit certificate is valid from 2026 to 2029. This not only highly recognizes Canlon's corporate reputation and brand value but also signifies the company's exemplary role in promoting the construction of the industry's credit system. Canlon has received this highest credit rating for many consecutive years.
On January 16, the No. 1 nuclear island of the Jiangsu Xuwei Nuclear Power Plant in Lianyungang began concrete pouring, marking the start of the main construction phase and initiating my country's transformation of nuclear energy from primarily power generation to diversified supply. The project utilized multiple waterproofing materials from Canlon to construct a robust and reliable waterproofing system. As the first nuclear power unit to commence construction in China at the start of the 15th Five-Year Plan period, the Xuwei project primarily focuses on industrial heating while also generating electricity, with a total investment exceeding 72 billion yuan.
On January 17, 2026, to strengthen the continuous exchange of new products and technologies in the steel structure field, implement the concept of high-quality development in the industry under the new circumstances, and jointly promote the continuous and healthy development of the metal enclosure system industry, a delegation led by Cai Zhaoyun, Secretary-General of the Metal Roofing Technology Branch of the China Building Waterproofing Association and the Enclosure System Branch of the China Steel Structure Association, visited Canlon for observation and exchange. Qian Lindi, Chairman of Canlon, Wang Pingping, Vice President, and Wang Yazhou, General Manager of the Application Technology R&D Center, warmly received the visiting branch presidents and directors.
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.
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.
