Sulfonamides--Rubber Accelerator NOBS (MBS) Properties: Light yellow or orange crystal (granule). No poison with a little odor of ammonia. The density is 1.34-1.40. Soluble in benzene, acetone. chloroform, insoluble in water, acid, and alkali with lower concentration. Application: An excellent delayed accelerator.
- Is MBS a good vulcanization accelerator?
- MBS is an excellent delayed accelerator. Its performance is similar to CZ with better scorch safety. Widely used in NR, IR, SBR, NBR and EPDM. Mainly used in manufacture of tyres, shoes and belts. Can be used alone or with other vulcanization accelerators such as thiurams guanidines and dithiocarbamates to improve the activity.
- What is rubber vulcanizing accelerator Nobs?
- Rubber vulcanizing accelerator NOBS, also known as N-Oxydiethylene-2-benzothiazole sulfonamide, is an excellent choice rubber vulcanization processes. NOBS is compatible with a variety of rubber materials, making it a versatile option for rubber manufacturers.
- What is MBS (Nobs)?
- MBS (NOBS) is a delayed active vulcanization accelerator,short curing time, high anti-scorching quality and safe processing. Physical and antioxidant quality of vulcanized rubber are superior. Mainly used for the manufacturing of tire, tube, shoes, rubber tape, conveyor belt, etc. CAS NO. 137-26-8 Performance:
- What is MBTs vulcanized rubber?
- Application: MBTS is a common accelerator for natural rubber, synthesis rubber and reclaimed rubber, which is easy to spread in rubber, no contamination. Vulcanized rubber has good antioxidant quality, but bitter, unsuitable for the rubber products contacting with food.
