| ●Characteristic: |
Faint yellow transparent thick liquid, The solidification point-19°C, the boiling point 530-540°C, dissolves in the acetone, the ethyl alcohol, the benzine and so on, does not dissolve in the water. Can decompose in the water and the acidic medium Does not have smelly, is tasteless, non-toxic stores stably. |
| ●Usage: |
This is the synthetic rubber the polyolefine plastic and so on the effective antioxidant, has heat-resisting, bears the oxidation, does not pollute and so on the characteristic.
In the synthetic rubber, affects the stabilizer which does not change color, does not have the influence to the curing, has the softened rubber the function, can suppress the gelatin the production, prevents in the rubber processing process the resinificationphenomenon, if and uses with the phenol class antioxidant, the protection potency enhances greatly, maintains the agglutination function in the bond, amount used general 0.3-1.0.
In the polyvinyl-chloride, the polystyrene, the vinyl fluoride polymer, the ABS copolymer and so on it is reposed in the hydrocarbon plastic, can prevent the gel gelation gelling, enhances its light stability, prevented the alkyl phenol changes color and so on. |
| ●Packing and store: |
1. Galvanizes the iron bucket packing, net weight 200kg/barrel.
2. When transportation the collision prevention and divulges, stores up in is cool, the dry storehouse, the heatproofing, guards against exposes to the sun, the waterproofing. |
