Donpipe 311 omi mimọ parapo polyols fun opo dimu
Ọrọ Iṣaaju
DonPipe 311 ni a irú ti parapo polyether polyol pẹlu omi bi ifofó oluranlowo, polyol bi awọn akọkọ aise ohun elo, adalu pẹlu pataki oluranlowo oluranlowo. O ti wa ni idagbasoke fun propping ti omi, epo tabi gaasi pipelines, aga ati awọn miiran awọn ọja, tun pẹlu ọrinrin ẹri ati ooru itoju awọn iṣẹ. Awọn polyurethane ọja pese sile nipa reacting o pẹlu isocyanate ni o ni awọn wọnyi anfani:
- ayika ore, lai run awọn osonu Layer
- Ga compressive agbara ti foomu
- Fine ki o si dan Foam cell , with good waterproof and moisture-proof performance
