Key Product Advantages

Perfect Heat Preservation Insulation

The high density and closed structure of selected raw material has the ability of low thermal conductivity and stable temperature, providing an excellent isolation effect for hot and cold media.

Good Flame Retardant Properties

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

Eco-Friendly Material

The environmentally friendly raw material is non-stimulating, non-polluting, and poses no hazard to health or the environment. It resists mold growth, deters pests, and offers excellent corrosion, acid, and alkali resistance.

Easy to Install & Use

Convenient installation that eliminates the need for additional auxiliary layers. The material is simple to cut and adhere, significantly reducing manual labor and installation time.

Product Presentation

Frequently Asked Questions

What is the safe operating temperature range for this insulation material?
