Pressure Resistant Expanded Polypropylene Epp Foam Raw Material

What is the raw material for EPP?

EPP (Expanded Polypropylene) is a type of foam material commonly used in packaging, automotive components, and sports equipment due to its lightweight, impact resistance, and thermal insulation properties.

The material properties of EPP can vary depending on the specific formulation and processing conditions, but some common parameters include:

1.Density: EPP foam typically has a density of 20-200 kg/m³, depending on the application.

2.Compression strength: EPP foam has a high compression strength, which means it can withstand significant forces without deforming permanently. The compression strength can range from 0.2 to 2.5 MPa.

3.Thermal conductivity: EPP foam has low thermal conductivity, which makes it an excellent insulator. The thermal conductivity can range from 0.03 to 0.05 W/m·K.

4.Elastic modulus: EPP foam has a low elastic modulus, which means it can deform significantly before breaking. The elastic modulus can range from 0.5 to 2 GPa.

5.Impact resistance: EPP foam has excellent impact resistance, which makes it ideal for use in protective packaging and automotive components. The impact resistance can range from 50 to 150 J/m.

6.These parameters can be tailored to meet specific application requirements by adjusting the formulation and processing conditions of the EPP foam.
