1. Description
Phosphite DB-1500 is equivalent to Mark-1500®
of Argus Chemical (US), which is superior over triphenyl phosphite
and phenyldiisooctyl phosphite in respect of safety. It can significantly
improve initial coloration and re-processability of plastic products.
When used in combination with organic tin or Ca/Zn compound heat
stabilizer, it produces good synergistic effect. It can be used
individually or as an active ingredient in compound preparations
for heat/oxidation stabilization of PVC, PE, PP, ABS, etc.
