ASC-CS220WR calcium silicate obtained a national patent in 1998. Withstand heavy rainfall (140 mm/h) for 1h, and the water absorption rate is less than 1%.
Contains a special anti-corrosion agent, which can effectively avoid corrosion under the insulation layer (CUI), making calcium silicate become one of the most difficult insulation materials to corrode pipelines. It has Certified the test of ASTM C692 and ASTM C871 and conforms to ASTM CT95 standard.
It is a kind of high-strength rigid thermal insulation material with a microporous structure (compressive strength ≥750 KPa), which can effectively prevent damage from bumps and tramples
Under the conditions of correct installation and use as required, ASC-CS220WR calcium silicate has superior physical strength and temperature resistance which will last for at least 35 years.
