Phenolic board has physical properties
phenolic insulation board has many advantages and a lot of unique physical characteristics, first of all, corrosion resistant ability is very strong, and almost all the resistance to many aspects of the acid, long-term exposed in the sun, so there is no obvious aspects of the phenomenon of aging, so has the very good resistance to aging phenomenon.
another is environmental protection, rock wool and glass cotton in the environment and human itself is no harm, polystyrene combustion heat will be resolved with a hydrogen cyanide, but phenolic board of gas are very clean and there is no fiber.
phenolic board trial temperature range is very wide, phenolic foam is affected by temperature is very small, will not happen in low temperature cold and some cold cui phenomenon, the mechanical strength is not changed. Density is small, and phenolic foam insulation board actually has the very good sound absorption performance, hole type for sound absorption is very favorable. And construction up very fast and has a high production efficiency.
