Puyang Changyu Petroleum Resins MB Powder is a non-staining secondary antioxidant for natural rubber, CR, SBR, NBR and EPR etc. Especially effective against heat oxidation in combination with amine.

Puyang Changyu Petroleum Resins TBBS(NS) Powder is a natural rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber and reclaimed rubber aftereffect accelerator, especially for the strong black rubber containing alkaline material. Safe operating temperature, anti-scorch strong, fast curing, high modulus strength, to improve the use of the proportion of synthetic rubber. Low toxicity and high efficiency, is an ideal alternative NOBS, with excellent performance, is called the standard accelerator. Widely used in the production of radial tires. Amines with aldehydes can, guanidine, thiuram accelerators and use, and scorch retarder PVI when used, constitutes a good vulcanization system. Mainly used in tires, shoes, hose, tape, cable manufacturing.

Puyang Changyu Petroleum Resins CBS(CZ) Powder is a highly reactive species aftereffect accelerators, anti-scorch performance, process safety, curing time is short. When a strong role in promoting the curing temperature above 138 ℃. Changing and CY TMTD, CY DPG or other alkaline accelerators cooperation with the second accelerator. Alkaline accelerators such as thiuram and dithiocarbamate salts to enhance its activity. CBS and CTP and use alternative NOBS, nitrosamines problems can be avoided by people concerned but also meet the same scorch safety performance and faster cure rate needs. Mainly used in the manufacture of tires, hoses, rubber, industrial rubber cables, etc. products.
