Best PU Sandwich Panel Manufacturers in Pakistan
The face material of the polyurethane sandwich panel is made of a high-quality color-coated steel plate. The core material is made of high-quality rock wool, glass wool, and high-density rigid foamed polyurethane as the groove filling.
After high-pressure foaming and curing, the cotton is automatically compacted and compounded by super-long precision double crawler control molding.
Compared with traditional hanging cotton enclosure materials, it has better fireproof and thermal insulation effects, longer performance, and superior thermal insulation performance.
The thermal insulation effect of the same thickness is twice that of the EPS sandwich panel.
The polyurethane cold storage panel has a large span, fast drainage, good waterproof effect, hidden screws so that it is not easy to rust, which extends the service life of the panel.
