Performance Characteristics Of Rubber Additives And Its
The diphenylguanidine accelerator DPG (D) is mainly used as an accelerator for natural rubber and synthetic rubber. Adding the accelerator DPG to the compound filled with high white carbon black can significantly reduce the Mooney viscosity of the compound rubber. Increase vulcanization speed. The active agent
Normally used Alone or with small quantities of ultra accelerator in tire compounds or industrial rubber products. Low poison and high efficiency. Can be used to effectively replace DM/DPG system. It may give equal modulus to CBS or NOBS when used at a 10% lower level. It is regarded as standard accelerator. Packing Types 25 kg.
Vulcanization accelerator functionalized nanosilica
The application of nanosilica in high performance tire highly depends on its uniform dispersion in rubber matrix. A series of dispersible nanosilica
This year, the price of rubber additives products increase overall. 6PPD, antioxidant RD, IPPD rose 35-40%, accelerator DPG rose as high 35%, and a large variety of vulcanizator DTDM promoter or 15%-25% promoter, recently a small variety of influencing factors also began to rise.
