ISINGENISO

DonSpray504 kuyinto fafaza lenhlanganisela polyols, uthule ejenti kuyinto 245fa esikhundleni HCFC-141B, ke ihlangana isocyanate ukuba umkhiqizo Foam esesikhundleni ukusebenza kakhulu, okuyinto zimi kanje,

1) esihle nekufana amaseli

2) ongaphakeme conductivity ezishisayo

3) ephelele ilangabi ukumelana

4) ezinhle aphansi-lokushisa ukuzinza ntathu.

Lusebenza zonke izinhlobo ezishisayo ukwahlukanisa ubunjiniyela esebenzisa ubuchwepheshe spray, ezifana amakamelo ezibandayo, amabhodwe, emikhulu ahamba ukwakhiwa metope njll njengoba
