Acid promoter. The thiazole accelerator is characterized by fast vulcanization speed, flat vulcanization curve, good comprehensive performance of vulcanized rubber, good aging resistance, wide application range, suitable for natural rubber and various synthetic rubbers, and should be combined with acid carbon black.

The same as the thiazoles, the same promoter groups, but one more anti-focus group and an activation group than the thiazoles. The promoting group is acidic and the activating group is alkaline. Therefore, the sulfenamide accelerator is an acid-base self-use accelerator, which combines the advantages of the thiazole accelerator and overcomes the shortcomings of ᱡᱚᱛᱚ ᱠᱷᱚᱱ ᱵᱟᱹᱲᱛᱤ ᱧᱮᱞᱚᱜ ᱠᱟᱱᱟ: 15 μm (meaning lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ kạmi lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạṛhi lạgit̕ lạgit̕ lạgit̕ lạgit̕ lạṛhi lạgit̕ lạṛhi lạgit̕ lạṛhi; (20) ᱜᱞᱩᱠᱚᱡᱽ, ᱜᱞᱩᱠᱚᱡᱽ, ᱜᱞᱩᱠᱚᱡᱽ, ᱟᱨ ᱜᱞᱩᱠᱚᱡᱽ ᱨᱮᱭᱟᱜ ᱜᱩᱱ ᱠᱚ ᱞᱟᱹᱜᱤᱫ ᱟᱭᱢᱟ ᱞᱮᱠᱟᱱ ᱡᱤᱱᱤᱥ ᱠᱚ ᱨᱮᱭᱟᱜ ᱵᱟᱹᱲᱛᱤ ᱫᱟᱲᱮ ᱠᱚ ᱨᱮᱭᱟᱜ ᱵᱮᱵᱷᱟᱨ; (᱓) ᱵᱟᱹᱲᱛᱤ ᱞᱚᱞᱚ ᱟᱨ ᱵᱟᱹᱲᱛᱤ ᱞᱚᱞᱚ ᱛᱮ ᱵᱮᱱᱟᱣ ᱟᱠᱟᱱ ᱱᱟᱹᱢᱩᱱᱟ ᱠᱚ ᱞᱟᱹᱜᱤᱫ;

It is also one of the more widely used categories in the rubber industry. The commonly used varieties are as follows: TMTM, TMTD, TETD, TRA. As can be seen from the structural formula, the general thiuram contains two active groups and two promoting groups. Therefore, the vulcanization rate is fast and the scorch time is short, which is an ultra-speed grade acid https://www.popeps.com ᱨᱮ ᱱᱚᱣᱟ ᱫᱚ ᱟᱜᱟᱢ ᱨᱮᱭᱟᱜ ᱡᱚᱛᱚ ᱠᱷᱚᱱ ᱞᱟᱹᱠᱛᱤᱭᱟᱱ ᱵᱤᱠᱚᱞᱯ ᱠᱟᱱᱟ ᱾

It can be seen from the structural formula that it is more active than the thiuram. In addition to the same active group and promoting group, it contains a transition metal ion, which makes the rubber unsaturated double bond easier to polarize than the thiuram. Faster, it is an ultra-fast grade acid accelerator. It has a very short induction period for room temperature vulcanization and vulcanization of latex products, as well as vulcanization of low unsaturation rubbers such as butyl rubber and EPDM, which impart excellent aging resistance to vulcanizates.

It is a moderately slow alkaline accelerator and is the most widely used alkaline accelerator. It is widely used in natural rubber and various synthetic rubbers. The most commonly used ones are DPG and DOTG, which are structurally active, have no promoting groups and other functional groups, are slow, and have good operational safety, but have a slower vulcanization rate.

Such accelerators have low promotion efficiency and poor scorch resistance. In addition to the use of chloroprene rubber and chlorinated polyethylene for promoting and crosslinking, other diene rubbers are rarely used. ETU and DETU are commonly used accelerators for neoprene.

It is a condensate of aldehyde and ammonia. It is a weak alkaline accelerator with 4/closed active amine groups. It is a slow accelerator and has no scorch hazard.

It is an acidic ultra-super-speed accelerator with faster vulcanization rate than dithiocarbamate. It is generally not used except for low-temperature glue and latex industry. Its representative product is ZIX, isopropyl. Zinc xanthate.
