Hangzhou Hi-Tech Fine Chemical DPG (D) is a medium-speed vulcanization accelerator for natural rubber and synthetic rubber. It is generally used as a second accelerator, as an activator for thiazole, thiuram and sulfenamide accelerators, and can be used for continuous vulcanization when used together with accelerators MD and TMTD. In neoprene, this product acts as a plasticizer and peptizer. The vulcanizate has relatively high tensile strength and resilience, and low heat build-up.

Hangzhou Hi-Tech Fine Chemical BZ (ZDBC) is a super-accelerator for natural rubber, synthetic rubber and its latex. Its effect is similar to that of PZ and EZ, but its activity is larger and its scorch tendency is small. When used in latex, the effect of this accelerator is better than that of PZ and EZ. The vulcanization rate above 100°C is fast, the vulcanization flatness is moderate when the temperature is below 120°C, and the vulcanization flatness is narrow when the temperature is higher than 120°C. The optimum vulcanization temperature is 95-110℃. Used for low temperature vulcanization mortar, it can be used for a week without early vulcanization. It is usually only used as a second accelerator when used in dry glue, and is a good active agent for thiazole accelerators. Products do not change color, do not pollute. The dosage is 0.5-2 servings.
