Low thermal conductivity, low water vapor transmission, high energy of foamed PP
Absorbency and compressibility make it suitable for filling voids on uneven surfaces, such as fillers, sealant holders, sealing strips, etc. in roofs, walls, concrete slabs, expansion joints of roads. PP foamed sheets can promote the solidification of concrete by reducing the loss of heat and moisture. With its low thermal conductivity, foam can be used as a roofing liner material for ordinary buildings, and PP foam liners can reduce the sound transmission of multi-story buildings. The surface of the foamed, smooth surface PP foam board (referred to as CD board) does not need to be shaved, and can be processed by tools and processing methods for processing wood.
The surface can be composited with fabric, metal sheet, film, wood grain or film, and can be processed by recycled materials. Use CD board as building template, no water absorption, no stick cement, good air permeability. PP synthetic wood can be obtained by adding reinforcing fibers to PP foam. PP synthetic wood has high strength, low thermal expansion, low creep, and 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 sports equipment such as life jackets, lifebuoy cores, surfboards, gymnastics blankets and sports mats, as well as swimming water materials and pool covers for beachside swimming pools.
Today, the choice of automotive materials is more lightweight, pollution-free, and recyclable. Foamed materials have become the preferred materials in the automotive industry. Therefore, green, environmentally friendly, and excellent PP foam plastics will have a broad space for development.
