Polyurethane Sandwich Panel

What is polyurethane sandwich panel?

Polyurethane sandwich panel is also known as polyurethane composite panel, polyurethane energy-saving panel and PU panle. The correct statement is that polyurethane insulation sandwich panels are used for construction.

Polyurethane sandwich panels are bimetallic, single metal and non-metal composite panels with polyurethane rigid foam as insulation layer. It is usually used for the wall and roof enclosure system of industrial plants, logistics storage and integrated houses.

Polyurethane Sandwich Panel

Characteristics of polyurethane sandwich panel:

(1) Low thermal conductivity. PU composite panel has small thermal conductivity and good thermal insulation performance. It is the best thermal insulation material.

(2) Beautiful plate shape and convenient installation.

(3) Polyurethane sandwich board has good fire resistance.

(4) Polyurethane composite panel is non-toxic and tasteless.

(5) Wide temperature range.

(6) Waterproof and moisture proof.

Polyurethane sandwich panel has beautiful appearance and good overall effect. It integrates load-bearing, heat preservation, fire prevention and waterproof. Moreover, it does not need secondary decoration. It has the advantages of fast and convenient installation, short construction period, good comprehensive benefits and good cost performance. PU panel is a kind of high-efficiency and energy-saving building envelope material with wide use and great potential, and it is also a new type of energy-saving board.

Polyurethane composite sandwich panels are widely used in energy-saving industrial plants, civil buildings, residential buildings, etc., with the advantages of beautiful atmosphere, energy conservation and thermal insulation, long service life, etc.

Introduction of polyurethane

Polyurethane (PUR) refers to a large class of polymers with more urethane groups in the main chain. It is a kind of polymer material between plastic and rubber. It has large elongation, wide hardness range, wide formula adjustment range, and excellent wear resistance and mechanical properties.

Polyurethane sandwich panel is produced by casting polyurethane elastomer process. Polyurethane is a kind of polymer that contains urethane type repeating structural units in the macromolecular chain. It is called polyamino acid ester in its full name and polyurethane in its full name in the UK, referred to as PU or PUR for short. Pu is the product of polyisocyanate and polyether or polyester polyol in a certain proportion.

Performance of PU elastomer: the performance of PU elastomer is slightly different from that of PU elastomer synthesized by plastic polyol. Polyester Pu has high mechanical properties, good oil resistance, but poor water resistance. The low temperature resistance and hydrolysis resistance of polyether Pu are better than those of polyester Pu, but the oil resistance and mechanical properties are slightly worse.

Mechanical properties of Pu: the hardness of PU elastomer varies widely from shore A10 to D80, with a breaking elongation of 800%. The shore hardness of natural rubber is only A70, and the elongation at break is 550%. PU elastomer has higher tear strength, 2-5 times greater than natural rubber. PU elastomer has high resilience and good shock absorption effect. PU elastomer has good wear resistance, which is 3-10 times that of natural rubber.
