This year's winter seems to be a little caught off guard. At the end of November, the first snowflakes have already fallen in the regions south of the Yangtze River. While admiring the beautiful scenery, we did not forget to introduce some knowledge of winter waterproofing to our friends. Today, let us learn about an important indicator of roof waterproofing materials!
Low-temperature bending is an important performance that reflects the environmental adaptability of waterproof membranes. Some waterproof materials may have excellent waterproof performance at room temperature, but they are easily damaged and destroyed in extremely low-temperature environments, and the service life and waterproof effect of the materials will be greatly reduced.
As a preferred material widely used in roofing, TPO thermoplastic polyolefin waterproofing membrane is often used in exposed environments, and requires higher requirements for low-temperature bending properties. The lowest temperature in northern my country can be as low as -40℃, and the roof is high from the ground and needs to withstand rain and snow. Therefore, special attention should be paid to this indicator in the selection of roof waterproofing materials.
Compared with conventional TPO products, the TPO products produced by Canlon CPCM factory have better flexibility, and can produce 5 types of H, L, P, G and GL , of which type P internally reinforced with polyester fibers, and G Using glass fiber internal reinforcement, GL uses glass fiber internal reinforcement with fleece backing structure, which can effectively improve its breaking strength, fatigue resistance, and puncture resistance, so that the membrane has better dimensional stability. Such a product can not only be bent without brittle cracking at -40℃, but also can be used for a long time in the environment of -60℃ to 135℃.
Exposed roof application effect
At present, Canlon TPO (type P) waterproofing membrane has mature engineering cases in the application of single-ply roof waterproofing. Xi'an Silk Road Culture and Art Center, which has the reputation of "Pearl of Bashang", has adopted Canlon 1.5mm TPO (Type P) Polymer waterproofing membrane as roof waterproof material.
Resist severe cold, no fear of winter—Canlon single-ply roof waterproofing system will give you the most reliable care.
