PERFECT HEAT PRESERVATION INSULATION

The high density and closed structure of selected raw materials provides extremely low thermal conductivity and stable temperature control, delivering an excellent isolation effect for both hot and cold media.

GOOD FLAME RETARDANT PROPERTIES

When exposed to fire, the insulation material does not melt, produces minimal smoke, and prevents flame spread to guarantee safety. The material is classified as nonflammable, with an operating temperature range of -50℃ to 110℃.

ECO-FRIENDLY MATERIAL

The environmentally safe raw material causes no irritation or pollution, posing no hazard to health or the environment. It actively prevents mold growth and rodent damage while offering outstanding resistance to corrosion, acids, and alkalis for an extended service life.

EASY TO INSTALL, EASY TO USE

Installation is simple and convenient. There is no need for extra auxiliary layers; the material can be cut and adhered directly, which significantly reduces manual labor and installation time.
