NBR (BUNA N)

   NBR弹性体可用于五种根基品级;基于丙烯腈含量,具有局部物理和化学属性。NBR 一般具有(凭据进步的 ACN 含量)较强的高温灵活性、较下的耐压缩变形性、透气性、革新的耐老化性和耐臭氧性、革新的拉伸和耐磨性、硬度和密度。NBR 用于需求优越的抗 –40 -www.7893.com到-威尼斯88330com +120°C 芳香烃(如垫圈和密封件、软管和电缆护套)的运用中,一般用于石油和天然气行业中。

下腈:>45% ACN 含量
中腈:30-45% ACN 含量
低腈:<30% ACN 含量

ACN 含量越下,抗芳香烃性越强。
ACN
含量越低,高温灵活性越好。
大多数运用的最好整体均衡为中等 ACN 含量。

   

NBR (BUNA N)

NBR elastomers are available in five basic grades; based on acrylonitrile content, giving proportional physical and chemical properties. NBR’-澳门威尼斯人38138s typically have (depending on increased ACN content), decreasing low temperature flexibility, increasing compression set, gas permeability, improved heat ageing and ozone resistance, improved tensile and abrasion strength, hardness and density. NBR-澳门威尼斯人娱乐城s are used where good resistance is required, to aromatic hydrocarbons at 40 to +120°C (e.g. gaskets and seals, hoses and cable jacketing), typically in the oil and gas industry.

High Nitrile: >45% ACN content
Medium Nitrile: 30-45% ACN content
Low Nitrile: <30% ACN content

The higher the ACN content, the higher the resistance to aromatic hydrocarbons.
The lower the ACN content, the better the low temperature flexibility.
The best overall balance for most applications is medium ACN content.
