PU/PIR (Wall)
Product Introduction
Introduction to polyurethane core materials
New polyurethane core material: The raw materials, combined polyether (white material) and isocyanate (black material), are mixed at a certain ratio through a high-pressure machine and then evenly poured between the upper and lower layers of the panel, forming through lamination and foaming.Its density is 40kg/m3, thermal conductivity coefficient is 0.021w/m.k, water repellency >98%, combustion performance B1, B2, B3 levels, with prices ranging from high to low.

It is made from a mixture of polyether polyols, catalysts, foaming agents, flame retardants, and other components. Domestic brands include Wanhua Chemical and Wanhua Rongwei; international brands include BASF, Huntsman, Bayer.

① The panels are uniform and stable with excellent thermal insulation and waterproof performance;
② Good airtightness (commonly used in cold storage);
③ Lightweight with an attractive appearance, effectively solving temperature differences in the refrigeration industry;
④ Easy and quick installation; sizes can be expanded or reduced according to needs;
⑤ Classified as B-level fireproof material;
⑥ Good surface flatness;
⑦ Superior water tightness;
⑧ No cold bridge phenomenon;
⑨ Lightweight structure;
⑩ Environmentally friendly and healthy
PU/PIR wall panel types
A. Water ripple effect, excellent decorative effect; under the influence of the water ripple effect, light shines on its surface creating light and dark stripes, extremely beautiful with a scene-changing effect. Effective width 1000mm, hidden screw connection.
B. Pure flat effect; smooth and even surface that serves as a decorative alternative to aluminum panel curtain walls. Effective width 1000mm, hidden screw connection.
C. Visible nail panel; can be made into square wave or pure flat effects; suitable for mobile houses, dismountable houses, telecommunication rooms, purification rooms, etc., with consistent inner and outer surfaces and tight connections.
