The commonly used vulcanization promoters in tire production are sulfonamide promoters and thiazole promoters.Thiazole promoters are non-toxic, but the characteristics of short burning time and slow vulcanization speed determine that they are mainly used as auxiliary promoters in the production of tires, with less actual consumption. The main applications are promoters M and DM.

MBS produces nitrosamine, which has been discontinued by tire enterprises in western developed countries and regions and is still used in China.In the production of tires often add a small amount of thiuram type accelerator as the second accelerator, the commonly used variety is disulfide tetramethylthiuram TMTD, the product can produce nitrosamines.The common variety of ᱮᱱᱡᱟᱭᱤᱢ ᱠᱚ ᱫᱚ ᱰᱤ ᱮᱱ ᱮ, ᱡᱟᱦᱟᱸ ᱫᱚ 25 mM-modioction ᱠᱚ ᱢᱮᱛᱟᱜᱼᱟ ᱾
 
All the three raw materials labeled above can produce nitrosamines harmful to human health. REACH regulation promulgated by the eu has clearly stipulated that the use of the above raw materials is prohibited for products exported to the eu.The following are several feasible and environmentally friendly alternatives for reference:

2. TBSI can be used instead of n-tert-butyl-bis (2-benzothiazole) sulfonamide. The coking is between NOBS and DZ, and the price is relatively low.TBSI chemical name n-tert-butyl-bis (2-benzothiazole) promoter, abbreviated as TBSI, is also a sulfonamide promoter.This product has the characteristics of prolonging coking time and slowing down vulcanization rate when used in rubber.TBSI compared with TBBS, due to the large molecular weight, good thermal stability, melting temperature is above 30℃ higher than TBSS, scorch time is long, curing speed, etc.At present, TBSS is commonly used with CTP, and TBSI can completely replace TBBS+CTP.In addition, TBSI is stable in water and easy to store.The reduction resistance of vulcanized natural rubber was improved obviously.It performs well in the compound bonded by rubber and steel wire.It is suitable for all elastomers, especially for thick products requiring high reduction.
 
3. It can be replaced by CBBS, which will not produce a promoter of n-nitrosamines. When it replaces NOBS in the same amount, its vulcanization rate is completely equivalent.Coke burning performance is slightly better than NOBS and CZ, the physical properties of vulcanizates and NOBS is also quite suitable for city tires and other rubber products.
 
4. XT580 can be used instead, n-aliphatic benzothiazol-sulfonamide, its performance is completely comparable to NOBS, and non-toxic, the price is lower than NOBS.

1. TBZTD (tetrasulphide benzylthiuram) can be used instead, with better coke safety and anti-reversion;The name of TBZTD is tetrasulfide benzyl thiuram, abbreviated TBZTD.This product is a newly developed thiuram type accelerator, which can replace TMTD(thiuram tetramethyldisulfide) and can be used as the main accelerator or assistant accelerator for quick vulcanization of natural rubber, butadiene butadiene rubber and butadiene butadiene rubber. It has better processing safety and longer burning time than TMTD.Due to the large molecular weight of TBZTD, melting point is high, it is difficult to decompose, ᱚᱱᱟ ᱠᱷᱟᱹᱛᱤᱨ ᱛᱮ MDMP ᱫᱚ ᱟᱹᱰᱤ ᱵᱟᱹᱲᱛᱤ ᱢᱮᱱᱟᱜ-ᱟ, ᱡᱟᱦᱟᱸ ᱫᱚ 5G ᱠᱷᱚᱱ ᱠᱚᱢ ᱜᱮᱭᱟ, ᱡᱟᱦᱟᱸ ᱫᱚ HPVs ᱠᱷᱚᱱ ᱵᱟᱹᱲᱛᱤ ᱵᱟᱹᱲᱛᱤ ᱢᱮᱱᱟᱜ-ᱟ, ᱚᱱᱟ ᱫᱚ CDPs ᱠᱷᱚᱱ ᱵᱟᱹᱲᱛᱤ ᱧᱮᱞᱚᱜ-ᱟ ᱾

1. Can use DTDC (N, N '- disulfide generation of caprolactam), a white crystalline shape, melting point is 120 ~ 122℃, active sulphur quality score greater than 0 19.It can replace the curing agent DTDM by the same amount without changing the formula and process of the compound.Similar to curing agent DTDM, curing agent DTDC can completely or partially replace sulfur to form effective or semi-effective curing system.As the vulcanizing agent DTDC can release active sulfur under the general vulcanization condition and form single sulfur bond and double sulfur bond between the added sulfur and rubber molecules, this rubber vulcanization network structure can endowing the vulcanized rubber with excellent heat resistance, compressibility and high tensile https://good.com ᱫᱚ https://goocal line lạgit̕ jạruṛaṭạṭạṭạṭạṭạṭạḍi lạgit̕ jạruṛ gạkhuṛ kạmi lạgit̕ jạruṛ gạkhuṛ kạmi lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕, ᱟᱨ 1.9 kg, ᱟᱨ 8 gml ar range lạgit̕ lạgit̕ lạgit̕ lạgit́ ᱠᱟᱱᱟ᱾
 
2. Alkyl phenol disulfide (vultac-5) can be used instead of alkyl phenol disulfide, which is suitable for rubber combination systems of different polarity and white tire side.
