PP foams are playing an important role in the construction field due to its performance advantages
Low thermal conductivity, low water vapor permeability, high energy of foamed PP
Absorption and compressibility make it suitable for filling voids on uneven surfaces, such as fillers for roofs, walls, concrete slabs, expansion joints for roads, sealant holders, sealing strips, and the like. PP foam panels can promote the solidification of concrete by reducing the loss of heat and moisture. With its low thermal conductivity, foams can be used for roofing materials in ordinary buildings, and through PP foam cushions can reduce sound transmission in multi-story buildings. The surface of the center foamed and smooth surface of the PP foamed plate (abbreviated as CD plate) can be machined without using a planing process, which can be processed with wood processing tools and processing methods.
The surface can be composite fabrics, metal sheets, films, wood chips or films, and can be processed using recycled materials. Use a CD board as a construction template, no water absorption, no sticky cement, good air permeability. Adding PP to the PP foam can produce PP synthetic wood. PP synthetic wood has high strength, low thermal expansion, low creep, similar performance to natural wood, and its outdoor exposure is better than natural wood. It is an important industrial material used for wood.
In addition, PP foam can also be used to make life equipment such as life jackets, lifebuoy cores, surfboards, gymnastics mats and exercise mats, as well as swimming and watering materials and pool covers for coastal swimming pools.
With the increasing emphasis on lightweight, non-polluting, and recyclable automotive materials, foaming materials have become the preferred new material in the automotive industry. Therefore, green, environmentally friendly, excellent PP foam will have a broad space for development.
