| Sekhutlo sa ho thellisa seretse | 55°-60° | 50°-55° |
| Ho khomarela ha biofilm | Bofokoli (bo sa rateng metsi) | E matla (bokaholimo ba polar) |
| Sekhahla sa phallo ea moralo (m/h) | 1.0-1.5 | 0.8-1.2 |
4. Phapang ho kenyeng
PP: Ho tjheseletsa moya o chesang (260-300 ℃) ho lokela ho sebediswa
PVC: E ka hokahanngoa le di-solvent kapa ya tjheseletsa mochesong o tlase (180-220 ℃)
