EPDM brief introduction

    full 称: Ethylene-Propylene-Diene Monomer

    in 文名称: ternary 乙丙橡胶

    structure features

    ternary is ethylene, propylene and non 共轭二烯烃 terpolymer. 二烯烃 tool has structure, has 两键之一 才 can copolymer, saturated and di main/primary is as is 交链处. 另一 不 saturated and formed is polymer 主链, formed is 边侧链. ternary main/primary polymer is full saturated and. this features make ternary can resistant hot, light, oxygen gas, especially is oxygen. ternary essence upper is property, for property solvent liquid and chemical material tool has resistant property, water absorption low, tool has good insulation features.

    in ternary production process in, through 改变三 mono 体 数 amount, ethylene propylene ratio, molecular weight and its distribution and methods can adjustment its features.

    ternary 乙丙橡胶 property can

    ternary 乙丙橡胶 is ethylene, propylene solvent liquid copolymer combined formed 橡胶, again 引入第三 mono 体（ENB）. ternary 乙丙橡胶 basic upper is types saturated and high poly material, resistant aging property can non good, resistant property good, electrical insulation property can excellent 良, chemical resistant property good, impact elastic property relatively good. ternary 乙丙橡胶 is ethylene, propylene solvent liquid copolymer combined formed 橡胶, again 引入第三 mono 体（ENB）. ternary 乙丙橡胶 basic upper is types saturated and high poly material, resistant aging property can non good, resistant property good, electrical insulation property can excellent 良, chemical resistant property good, impact elastic property relatively good.

1, low density high filling property

ternary 乙丙橡胶 is 一 types density relatively low 橡胶, its density is 0.87. add can a large amount of and add filling agent, can reduce products cost, 弥补 ternary 乙丙橡胶生胶 price high disadvantages, and for high value ternary 乙丙橡胶 说, high filling rear material machine can reduce degree large.

2, resistant aging property

乙丙橡胶 has excellent resistant 天候, resistant oxygen, heat resistant, resistant acid alkali, resistant water 蒸汽, color stability property, electrical property can, property and normal temperature flow property. ternary 乙丙橡胶 products in 120℃ lower can long use, in 150- 200℃ lower can short or use. add 入适宜 anti agent can improve/increase its use temperature degree. oxidation material crosslinked ternary 乙丙橡胶 can in conditions lower use. ternary 乙丙橡胶 in oxygen concentrated degree  50pphm, tensile 30% conditions lower, can 达150h above crazing.

3, corrosion resistant property

due to 乙丙橡胶缺乏极 property, saturated and degree low, for various property chemical product alcohol, acid, alkali, oxidation agent, made cold agent, agent, material 油, ketone and and other has relatively good resistant resistant property; in and solvent agent （如汽油, and other ） and material in stability property relatively 差. in concentrated acid long function lower property can need decline. in ISO/TO 7620 in 汇集 近400 types tool has property gas and liquid chemical product for various property can function material, 并规定 1-4 grade table/sheet its function degree ,腐蚀 property chemical product for property can effect/influence :

and other grade  体积  solvent rate /%  hardness reduce value for property can effect/influence:

• 1 <10 <10  light micro or 无

• 2 10-20 <20  relatively small

• 3 30-60 <30  in and other

• 4 >60 >30 严 heavy

4, resistant water property can

乙丙橡胶 has excellent resistant water property can excellent its heat resistant property. in 230℃ hot in, 近100h rear appearance 无变化. fluorine 橡胶, silicon 橡胶, fluorine silicon 橡胶, 丁基橡胶, 丁腈橡胶, 天然橡胶 in conditions lower, relatively short time appearance obvious poor phenomenon.

    applications  

    suitable for heat resistant belt/tape, 蒸汽胶 tube/pipe, decrease and anti water material, also can manufacturing automotive use parts, construction material, and other industrial products.

    market current situation

   随 我国经济开始回暖, automotive, construction and other industry fast speed development 期, obvious ternary 乙丙橡胶 market demand amount. in 商情报网 data 显示, 2012 year China ternary 乙丙橡胶 output/production volume to 1.91 10,000 tons, table/sheet 观消费 amount to 22.75 10,000 tons, industry Imported degree very high.

   随 我国经济总 amount improves, as is industry automotive industrial fast speed development, future 一段时期 still will is ternary 乙丙橡胶 in upper industry fast speed development 期, add upper basic construction, high speed iron 路, rail transit construction and other development, will China ternary 乙丙橡胶 market 进入一 demand high 峰.
