橡胶 positive 牌胶就 is positive product, combined product. off-brand is product production 发生波动, indicators to related standards requirements, 严格说 is 不允许出场. this category of very more is large type production enterprise 产出 次 product, off-brand 名字, relatively low price sales.

off-brand is in production process in has 瑕疵, its property can and positive versus large, can can 会不太 stability in requirements high parts in generally has issues. off-brand separation, has is color issues, has is odor issues, has is material property issues. therefore off-brand 也千差万别, has off-brand 既便宜 also can meet/satisfy production requirements, therefore off-brand also is very 吃香.

off-brand 橡胶, is production 厂, production certain indicators combined product. ratio 如门尼 or high or low, acrylonitrile content or high or low or other. is off-brand 生胶出厂时候不会告诉你 to is indicators combined 格, positive is has issues.

this type of 情况, generally requirements use this off-brand front 做 检验工 as, （万一EPDM in mono content more, speed degree fast very more. false lower ）, therefore off-brand 生胶不 is 拿 就 can use.

既然 is off-brand, table/sheet it property can is unstable, can and other low one-time use off-brand ML very high. and other lower month again off-brand ML also very low, this is can 避免. is reduce cost, also is has necessary use off-brand.

每 生胶 production is according to viscosity design grade, is grade has 一门尼 viscosity 区间, production issues, or Raw Materials issues, reaction temperature degree, pressure and other issues, effect/influence product viscosity, production 出 不符 combined requirements 生胶, is off-brand.

true positive off-brand NBR relatively positive generally is viscosity data unstable （偏 low or high ）, main/primary effect/influence is formulation system 变化, generally structure simple parts can use, in export combined issues, if 担心风险 issues, 建议并 use, ratio/proportion 由厂家 for off-brand material use 熟练情况 control, use basic upper effect/influence product quality.

another off-brand causes mono mono is viscosity causes, has waste has （ 滤之 rear has 杂质）, or 者乳胶也 has, 处理未 dry water has.

总之 off-brand in property can requirements high product application upper basic is has large issues, comparison coarse parts upper has issues, footwear materials has issues. key/critical is 每次都 need use can use.

说说 positive and off-brand 橡胶

has 朋友问 off-brand is what? 总听别人说 off-brand 胶, positive 牌胶.

我打 ratio 方, 就说手 machine 吧, has and water 货, can use, price different, in has positive and off-brand.

准确 说, off-brand, is quality upper ratio positive material 会差一, off-brand in separation and other grade, and other product, and other product, product; 不 也 has very more recycled material 也拿 当 as off-brand material. currently off-brand comparison 畅销, main/primary causes is off-brand material price low, need formulation process and use methods, positive 牌, off-brand mixed combined use, reduce material cost, but also has product requirements high, can full use off-brand 代替.
