PURWAKA

DonSpray504 iku semprotan polyols gabungan, ndamu agen punika 245fa tinimbang HCFC-141B, apa sing ditanggepi karo isocyanate kanggo gawé umpluk kang pagelaran banget, kang minangka nderek,

1) nggoleki lan uniformity sel

2) termal doyo kurang

3) semangat perlawanan sampurna

4) dimensi stabilitas-suhu kurang apik.

Ditrapake kanggo kabeh jinis engineering termal jampel kang migunakake teknologi semprotan, kayata kadhemen kamar, panci, pipelines gedhe-ukuran lan construction metope etc.
