  • Calcium silicate insulation materials are generally composed of lime, siliceous raw materials, etc. They have the characteristics of good fire protection, waterproof, light weight, high strength, long service life, heat insulation and sound absorption, and are widely used in the petrochemical industry.

    The company has built a new, intelligent production line, using raw ore wet soil and lime as the main raw materials, specializing in the production of microporous calcium silicate insulation products, with a first-phase production capacity of 60,000 cubic meters. Products of various shapes and specifications can be customized according to customer requirements, and can be used in flat plates, straight pipes, tees, elbows, flanges, insulated pipe supports, etc. to provide customers with efficient, long-term and durable insulation products.

    After authoritative testing by a national testing agency, the company's product appearance quality, dimensional deviation, physical properties and other indicators all meet the requirements of the GB/T 10699-2015 "Calcium Silicate Insulation Products" standard, including compressive strength, flexural strength, etc. The measured data of the indicators have reached the top level in the industry.

    The company has also made breakthroughs in product research and development, successfully developing surface and overall hydrophobic calcium silicate products with a hydrophobic rate of greater than or equal to 99%.
