Polymer Type |
| Thermoplastic |
Advantages |
| Good stiffness, hardness, dimensional stability and reduced creep compared with unmodified PP. Improved flow properties compared with material of same calcium carbonate loading. |
Disadvantages |
| Modification causes embrittlement; poor surface appearance and low elongation at break compared with unmodified PP. |
