antimony ethylene glycol
specifications:
appearance: white crystal
content of antimony(sb): 56-58.8%.
loss on drying: 0.6% max.
as: 0.01% max.
pb: 0.0011% max.
comparing with antimony acetate and catalyst antimony trioxide, it has the following advantage points:
1. solubility and disperse are very good in the glycol solution .
2. antimony content hightly, good activity and improve throughput in set.
3. this catalyst can,t adhibit new impurity, make slice to improve immanence quality, and improve to machining slub.
4. it can make slice color better and improve caloric stability.
antimony ethylene glycol:
property: the white mini-crystal; can dissolve in the glycol; easy to absorb moisture in the air, and need to be strictly kept sealed.
usage: mainly used in the polyester production, such as bottle-grade, film-grade and textile chips.
package: · the product is kept sealed in the polyethylene container, nw 20 kg;
· the product is kept vacuum in the aluminum-plastic composite bag, nw 25kg;
· every 36 barrels are palletized according to the international standard, nw 720 kg or 40 barrels, nw 1000 kg.
