         antioxidant is what

         antioxidant is for material oxidation process tool has retardant and resistant function type material 质. its types type non 常丰富, has low molecular weight, has polymer/macromolecule amount; has 天然, has combined formed.

         antioxidant classification

        1, antioxidant

        典 type antioxidant below/following type:

        芳香 amine type antioxidant: amine type resistant oxidation agent 几乎都 is aromatic amine material, main/primary has 二芳基仲 amine, for amine and ketone amine, aldehyde amine and other type. it large more tool has relatively good resistant oxygen can, easy generate color 污, main/primary used for industrial and polyurethane ester products in.

        受 retardant type antioxidant: use most 广泛 一 type antioxidant. resistant oxygen can generally relatively amine type antioxidant low, has property, main/primary used for plastics and shallow color products. many has product 如1010, 1076, belongs to this type.

        2, antioxidant

         main/primary is 硫代二丙 acid ester and other ester and acid ester large type. it main/primary used for polyolefin in, and type antioxidant use, generate function.

        亚磷 acid ester is use most 广泛 辅助 antioxidant, type product 如168.

        硫 ether is type antioxidant, type product 如DLTDP and DSTDP.

        3, metal agent

         polymer and heavy metal 接触时, heavy metal catalytic function make polymer generate degradation reaction, cable material is copper, 常引起 copper 害, 因而需添 add copper 离子钝化 agent, metal agent can large degree improve/increase polymer stability property.

         Common antioxidant grade

        1, antioxidant 1010

        1010 antioxidant testing indicators ‍ application scope:

         polyolefin: PP Film, PP Molding, HEPE Pipe, PP/HDPE Tape/ PE Wire&Cable, PE Molding, LDPE/EVA Film, LLDPE Film

         elastomer: EPDM

         polyurethane ethylene: PVC

         polyurethane ester: RIM, TPU

         engineering plastics: POM, PA, PBT/PET

        2, antioxidant 1076

1076 antioxidant testing indicators

         application scope:

         polyolefin: PP, PE, LDPE, EVA, LLDPE

         styrene: ABS, PC/ABS, IPS, GPPS

         elastomer: S-SBR, BR, EPDM, SBS/SRS, TPE

         polyvinyl chloride (PVC): PVC

         polyurethane ester: RIM, TPU

         engineering plastics: PC, PMMA

        3, antioxidant 168

168 antioxidant indicators

         application scope:

         polyolefin: PP, PE, LDPE, LLDPE, EVA

         styrene: ABS, PC/ABS, IPS, GPPS

         elastomer: S-SBR, BR, EPDM, SBS/SRS

         engineering plastics: PA, PC, PBT/PET, PMMA

         Domestic antioxidant and Imported antioxidant to has 无差距

        据知名石化 enterprise for retardant antioxidant 1010 and acid ester antioxidant 168, using/adopting 3 types Domestic product and 1 types Imported product detailed comparison research. research according to industry standards, for product appearance, melting point scope/range, 挥发份, ash content, solvent liquid degree, solvent liquid light transmittance, content and has separation 均进行 testing. research also testing antioxidant 1010 has machine content. has machine content high 1010 in application 方面会受 to made. another, research for antioxidant 168 testing long hydrolysis testing time, testing to to has product 均发生 hydrolysis is 止.

        结果显示:

        1, 3 types Domestic antioxidant 1010均完 full combined industry standards indicators, property can and Imported product versus 近, in generally production in can and other use.

        2, its in 1 types Domestic antioxidant 1010 using/adopting catalytic agent, in certain application in, requirements antioxidant using/adopting process, need attention/notes selection versus 应 厂家.

        3, 3 types Domestic antioxidant 168 hydrolysis resistant can force combined or ultra- industry standards, for Imported antioxidant 168 hydrolysis resistant can force most good.
