character: The product is a non-toxic, flammable light yellow particles, sulfur is a common allotrope, which is a large number of sulfur atoms from the linear polymer by polymerization, insoluble in sulfur oxide and other solvent
uses:  It is a natural rubber, butadiene rubber, styrene-butadiene rubber and a variety of environmental clean rubber vulcanizing agent. Can improve the dispersion in the rubber, so that uniform quality products to improve the surface quality and can reduce the mixing time, lower energy consumption, reduce dust pollution, reduce environmental and health hazards. Specific advantages are as follows:
1.This product is dispersed in the rubber in a state of existence, making plastic materials do not emit cream, and a good adhesive, at the same time can guarantee the quality of the appearance of light-colored products.
2. This product is distributed evenly in the rubber compound to effectively resist the accumulation of sulfur to reduce the storage of the process of rubber tend to scorch.
3. The rubber goods in the adjacent layer so that no migration. Especially in the butadiene rubber and butyl rubber of the rubber compound and the general migration of sulfur at high velocity, with increase after the insoluble sulfur can be avoided.
4. This product reduces the curing time. When post-curing temperature, it has an "activation phase", that is, the role of chain depolymerization, so that curing speed and reduce the amount of sulfur will help to improve the aging properties of products.
Dosage: 0.3-5 were generally rigid plastic 5-30
storage: According to the general provisions of storage and transportation of chemicals, stored in a cool, dry place, fire prevention, protection, anti-rain, carrying, unloading lightly。
Packing :
Note: carton with plastic inner, net weight per bag 25kg.。
The advantage for Master batch
1.Higher active content    2.Better dispersiveness  3.Shorten the  mix and smelt time    4.It is better with the compatibility of the sizing  material   5.There is no dust to fly upward, improve the working environment     6. Easy to operate, benefit and weigh automatically.
