Function:

rubber various accelerator masterbatches from China factories are mainly the aftereffect accelerator of natural rubber, butadiene rubber, isopentyl rubber, styrene-butadiene rubber, and reclaimed rubber, especially suitable for carbon black rubber with strong alkalinity. rubber various accelerator masterbatches are safe at operating temperature, have strong scorch resistance, fast vulcanization speed, and high tensile strength, which can improve the use proportion of synthetic rubber. With low toxicity and high efficiency, it is an ideal substitute for NOBS and has excellent comprehensive performance. It can be used together with the promotion of aldehyde Amine, Guanidine, and Thiuram, and with the anti-scorching agent PVI to form a good vulcanization system.

Application:

Tire, conveyor belt, rubber shoes, rubber hose, cable sheath, and other industrial products as well as shoe material products.

Storage:

Keep rubber various accelerator masterbatches in a dry and cool place, away from heat or direct sunlight. Keep in original packing and sealed for one year

Dosage: the general dosage is 0.50PHR-2.0PHR

When choosing rubber various accelerator masterbatches, we should choose the right type of accelerator for different rubber materials, and the following factors should be considered.

• Vulcanization speed.
• Rubber type Different rubber adopts different vulcanization systems, which includes the selection and matching of accelerator type.
• Coking performance accelerator has a decisive influence on the burning time of rubber, so the choice must ensure that the rubber is not vulcanized prematurely in the general processing (mixing, calendering, pressing out).
• Vulcanization rubber resistance to vulcanization reversion which is particularly important in the original product, because of the poor thermal conductivity of rubber, heat parts should be selected with good resistance to reversion of rubber accelerator, so as to avoid the reduction of rubber in the vulcanization process.
• Vulcanization rubber performance selection accelerator, in addition, to ensuring the processing of rubber, but also to pay attention to meet the requirements of product performance, can be adjusted by the vulcanization system to improve the physical and mechanical properties of vulcanization rubber and aging resistance.
