ETERPAN (the Chinese translation of the registered trademark "ETERPAN") is a fiber-reinforced silicate flat plate (fiber cement board) whose main raw material It is cement, plant fiber and mineral matter, which is made by high-temperature autoclaving using the slurry method

Calcium silicate board, also known as gypsum composite board, is a porous material with good sound insulation and heat insulation properties. When the indoor air is humid, it can attract water molecules in the air, and when the air is dry, it can release water molecules, which can appropriately adjust indoor dryness and humidity and increase comfort. Gypsum products are special fireproof materials that can produce endothermic reactions in flames. At the same time, they release water molecules to prevent the spread of fire, and will not decompose to produce any toxic, corrosive, or suffocating gases, nor will they produce any Combustion aid or smoke.
