The product is masterbatch-specific heat insulation medium, it can be added into plastic slices to produce heat insulation masterbatch. The product has two forms: powder and liquid, the powder is suitable for dry granulation process, while the liquid for wet granulation.
Flexible choices according to clients’ equipments, choose liquid or powder product;
Good chemical stability, small primary particle size, storage for long time;
Good compatibility with plastic plastics, no precipitation;
High heat insulation rate, the blocking rate of UV and IR is over 99%;
Strong weather resistance, after QUV 5000h test, no degradation, no color change;
Safe and reliable, no toxic and hazardous substances such as halogen, heavy metal, etc.
It can be used to produce heat insulation masterbatch, and polymer type can be PET/PE/PC/PMMA/PVC, which is widely used for film, board, yarn, etc.
(1)the liquid for wet granulation
Add the liquid into the PET during front-end production, during the esterification process of phthalic acid (PTA) and ethylene glycol (EG), the liquid is added into ethylene glycol by 8-10% dosage, and it can participate in esterification directly under the effect of catalyst, then heat insulation masterbatch is obtained.
(2)the powder for dry granulation
Add the powder into the PET plastics during back-end production. The powder is mixed with normal PET powder uniformly by dosage of 1.2-2%, then add them into twin turbo extruder slice, then transparent heat insulation masterbatch is obtained.
Liquid: 20 kgs/barrel, store in a cool, dry place, avoiding sun exposure.
Powder: 25 kgs/bag, store in a cool, dry place, avoiding sun exposure.
