Puyang Changyu Petroleum Resins MMB Powder can be used for natural and synthetic rubbers. As it is secondary antioxidant, ever better effects can be developed when used together with other antioxidants. Furthermore, when it is employed in case of sulfurless vulcanization higher heat resistance can be obtained, it also serves as an accelerator of CR and heat sensitizing agent for latices. It is effective not only white and light colored articles, but also for rubber products of all types. But unsuitable for food processing.

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 PVI(CTP) Crystal is a pre-vulcanisation inhibitor. Provide predictable scorch control in most sulfur valcanisation; Improved cost performance through marginal stock recovery, single- stage mixing, higher processing and/or curing temperatures; activity is linear and higher than most retarders; may cause bloom above 0.5 phr. It is the anti-scorching agent for both natural and synthetic rubber.

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 MBZ Powder is a non-staining secondary antioxidant for NR, CR, EPR, SBR, NBR, etc. Especially effective against heat oxidation in combination with amine. Could be used alone or combined with the anti-degradants, such as DNR or AP.

Puyang Changyu Petroleum Resins NDBC Powder is used as accelerator for most sulfur-cured elastomers, can provide ozone resistance in dynamic application, as excellent anti-oxidant in usual application. NDBC can protect CR, CSM, CO, ECO from oxygen and also used for EPDM and CSM vulcanized rubbers and colored CR products.

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.
