Synthetic rubber
IIR Sheet (Isobutene-isoprene rubber : Butyl rubber)
【 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.
*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 ().
