Kopo
PVC Resin SG-3 Kopo ea ho:
1. Boemo ba PVC
Profiles ke tšimo ea tšebeliso ea PVC naheng ea malapeng, hoo e ka bang 25% ea kakaretso ea tšebeliso ea PVC, haholo-holo bakeng sa ho etsa mamati le lifensetere le thepa ea ho boloka matla, 'me kopo ea bona e ntse e le khōlō le kgolo.
2. Pipe ea PVC
Liphaephe tsa PVC ke indasteri ea bobeli e kholo ka ho fetisisa ea tšebeliso, Tšebeliso ke 20% ea kakaretso ea bokhoni ba tlhahiso naheng ea China, Pipe ea PVC.
3. Filimi ea PVC
Filimi ea PVC e kentsoeng ke karolo ea boraro e sebelisoang ka bongata, e ka bang 10% ea kakaretso ea tlhahiso.
