LJ rigid foam polyurethane composite cross-linked polythylene mat

The LJ rigid foam polyurethane composite cross-linked polythylene mat produced by our company is bonded together by rigid foam polyurethane and polyethylene closed-hole foam through infrared light wave technology, and the surface is composite glass fiber felt, the composite mat made of vibration attenuation, sound insulation and heat preservation.


LJ rigid foam polyurethane composite cross-linked polythylene mat is mainly used on the floor of the building in the heat insulation project of residential building floor slab. In application, it has the characteristics of heat insulation, noise reduction and sound insulation, moisture-proof and antibacterial, health and environmental protection, simple construction technology, etc.

Damping principle

When people step on the floor slab or generate vibration in other ways, the vibration will spread through the Sound Bridge generated by the rigid connection of floor materials. For example, the floating construction method is adopted in the floor structure, adding a layer of LJ rigid foam polyurethane composite cross-linked polythylene mat can avoid the Sound Bridge generated by the rigid connection of the material layer, thus obviously weakening the propagation of vibration and achieving good vibration attenuation effect.

Product advantages

It does not contain benzene, xylene and other organic volatile substances harmful to human body, and it is healthy and environmentally friendly.

It has the advantages of heat insulation, vibration attenuation and sound insulation, simple and convenient construction, etc.

Characteristics

LJ rigid foam polyurethane composite cross-linked polythylene mat is made ofcross-linked polythylene mat which is compounded by infrared hot melt and glass fiber felt, and then composite by infrared hot melt and rigid foam polyurethane, it is used on the floor of the building in the heat insulation project of residential building floor. In application, it has the characteristics of heat insulation, noise reduction and sound insulation, moisture resistance and antibacterial, health and environmental protection, simple and convenient construction, etc.

storage

Packing

Polyethylene packaging film packaging, adhere to the green, environmental protection principle, packaging film recyclable; can also be determined by the supply and demand parties through negotiation. The appearance of the packaging film or the certificate of qualification should be clearly marked: product name, manufacturer name, production address, product standard number, product specification and size, production date, etc.
