Lately, the Ministry of industry and information technology announced the approval of the 643 industry standards, including 10 rubber additives industry standards, the implementation date is July 1, 2016.
Rubber additives industry standard number, name, main contents are as follows:
|
1 |
HG/T 4890-2016 |
vulcanization accelerator (TMTM) |
This standard specifies a vulcanization accelerator four methylthiuram (referred to as Thiofide TMTM) requirements, test method, inspection rules, marking, packaging, transportation and storage. This standard applies to two methylamine and carbon disulfide as the main raw material to prepare accelerator TMTM. |
|
2 |
HG/T 4891-2016 |
vulcanization accelerator (ZBEC) |
This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation and storage of two benzyl zinc dithiocarbamate (ZBEC), which is a kind of benzyl sulfide accelerator. This standard applies to two benzylamine, carbon disulfide and zinc compounds as the main raw material to prepare accelerator ZBEC. |

HG/T 4895-2016 |
Rubber antioxidant (8PPD/TMQ) |
This standard specifies N- (1- methyl heptyl) - N "- phenyl-p-phenylene diamine (8PPD) and two 2,2,4- three -1,2- two hydrogenation of methyl quinoline polymers (TMQ) compound (referred to as rubber antioxidant 8PPD/TMQ complex) requirements, test method, inspection rules and signs, packaging, transportation, storage and security. This standard applies to 8PPD and TMQ according to the ratio of approximately 7:3 heating rubber antioxidant 8PPD/TMQ complex composite prepared. |

4 |
HG/T 4898-2016 |
Rubber antioxidant (6PPD/7PPD) |
This standard specifies the N-1,3- two -N '- phenyl methyl butyl benzene amine (6PPD) of two N-1,4- and two -N' - phenyl methyl amyl benzene amine compound two (7PPD) (referred to as rubber antioxidant 6PPD/7PPD complex) requirements, test method, inspection rules, marking, packaging, transportation, storage and security. This standard applies to 6PPD and 7PPD in accordance with the ratio of about 4:6 heating rubber antioxidant 6PPD/7PPD complex composite prepared. |
