1.Raw materials and production process
EPDM sealing strip:
Raw materials: Made from nationally recommended sealed and environmentally friendly materials, free from heavy metals and formaldehyde.
Production process: After vulcanization treatment, it has high strength and good elasticity, with small deformation and a bright appearance. The entire production process is relatively environmentally friendly and will not cause significant pollution to the environment.
Silicone sealing strip:
Raw material: Silicone rubber is a natural, non-toxic, and harmless polymer material.
Production process: The production and processing technology of silicone sealing strips is environmentally friendly, without the need to add solvents and chemical additives, and will not cause pollution to the environment. Meanwhile, the waste generated during the production process can be recycled, further reducing its impact on the environment.

Due to its ozone resistance, EPDM is also known as the "crack free rubber", especially when applied to various urban buildings with different atmospheric indices and completely exposed to the air, it will demonstrate the superiority of its products:
Anti ultraviolet radiation provides environmental protection for high-rise building residents; It can withstand voltages of 60~150KV, and has excellent resistance to corona discharge, electrical cracking, and arc. Low temperature elasticity, the temperature at which the tensile capacity reaches 100MPa is -58.8 ºC. Therefore, the product is significantly superior to other material sealing strips in terms of service life, high and low temperature resistance, and usage cost. The longest lifespan can reach 30 years.
