The density of recycled pp granule is relatively small (0.91g/cm^3), which is actually the lowest among commonly used plastics. recycled pp granule had very good stress cracking resistance and high bending fatigue life. recycled pp granule has good adhesion. PP products can be used for a long time in the high temperature environment below 100 degrees. The temperature to 150 degrees or so will not be easy to deformation.
