IIR Sheet (Isobutene-isoprene rubber : Butyl rubber) 画像1

Features

  • ・Excels in chemical resistance.
  • ・Excels in gas permeability resistance.
  • ・Excels in heat aging resistance.

Applications

  • ・Packing material for air (gas) duct.
  • ・Acid resistant packing material.
Function ・ Ozone Resistance ・ Acid Resistance ・ Alkali Resistance ・ Anti-Permeability to gas

*Hardness measurement is revised to “After 3 seconds” according to JIS K 6253 (2006). However, generally, the conventional "measurement within 1 second" is to be the mainstream for nominal hardness, so this result is measured value and the measurement result after 3 seconds is shown in ().
