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 NDMC Powder is a anti-oxidant for epichlorohydrin compounds. Improves retention in media that produce high swell and/or high extractability. NOMC is also an outstanding anti-oxidant for peroxide-cured elastomers (like EPOM or EPM).

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 MBT(M) Powder is mainly used for the IR, NR, SBR, NBR, HR, and EPD system is currently a major acidic curing agent, curing with a medium speed, and other curing agents such as CY DM and CY TMTD alkaline curing agent can be achieved with higher activity, the curing temperature is low, easily dispersed in rubber, no pollution, mainly used in the manufacture of tires, various power belts, conveyor belt, belt, shoes and other industrial rubber products, but can not be used as food ingredients. MBT's use vulcanized rubber, which is relatively low modulus, but good anti-aging properties to obtain a faster cure speed and high modulus, can be used to help promote agents, such as ZBEC, ZDEC, TMTD or DPG in EPDM and butyl rubber vulcanization, MBT is in many existing conventional cure system component, MBT may also be used for latex foam vulcanization system.

Puyang Changyu Petroleum Resins ZMBT(MZ) MZ-15 Powder is mainly used together with ZDMC and ZDEC as primary accelerator for latex; can achieve higher modulus of valcanized latex. In addition, it can achieve good compressive deformation resistance without additional curing time. ZMBT will not affect the stability of latex.

Puyang Changyu Petroleum Resins ZMBT(MZ)-LOW MZ(high M+) Powder is mainly used together with ZDMC and ZDEC as primary accelerator for latex; can achieve higher modulus of valcanized latex. In addition, it can achieve good compressive deformation resistance without additional curing time. ZMBT will not affect the stability of latex.

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 MBTS(DM) Powder has medium curing rate in NR and SR; suitable for most general rubbers; Used as plasticizer and delay agent in chloroprene rubber. It is usually used together with secondary accelerator in the synthesis of polymers; has better scorch safety than MBT.

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.
