丁基橡胶
丁基橡胶是由异丁烯和少量异戊二烯共聚而成的，主要采用淤浆法生产。透气率低，气密性优异，耐热、耐臭氧、耐老化性能良好，其化学稳定性、电绝缘性也很好。 丁基橡胶的缺点是硫化速度慢， 弹性、强度、粘着性较差。丁基橡胶的主要用途是制造各种车辆内胎， 用于制造电线和电缆包皮、耐热传送带、蒸汽胶管等。

性能:
丁基橡胶产品为灰白色似的橡胶状固体，密度为0.92g/cm3，无味，不溶解于水，能溶于己烷、氯仿中；产品还具有透气率低、气密性好，良好的抗臭氧性、耐化学腐蚀性、电绝缘性、耐屈挠性，还具有耐热老化性、吸收能量等特性。
# U! |5 X, V0 rApplication
IIR finishes is a rubbery solid in ash grey with the density of 0.92g/ cm3. It is tasteless, insoluble in water and is able to dissolve in hexane and trichloromethane. Its products features low air permeability, good air tightness, excellent ozone resistance, chemical resistance, electric insulativity, flexing life, thermal aging resistance and absorbed energy property etc.
用途
丁基橡胶主要适用于轮胎内衬及内胎、硫化胶囊、医用瓶塞、电绝缘材料、密封材料、电缆头薄膜等行业。目前燕山生产的IIR1751牌号的丁基橡胶是制造子午胎内胎和无内胎轮胎不可替代的材料。

The main usage of IIR covers the industries for tyre innerliners, innertubes, sulfurized capsules, and medical use bottle block, electrical insulation, caulks and membranes etc.
IIR1751, which is available now is the non-replaceable material for manufacturing meridian tube and tubeless tyre.
