Kuraray - Liquid Isoprene Rubber (LIR)

LIR is a transparent, odorless liquid isoprene rubber. Having characteristics as a reactive plasticizer, LIR can soften rubbers when used in kneading rubber, in addition to acting as a cross-link with rubber when shaping it. The existing rubber plasticizer (mineral oil) degrades rubber`s properties by oozing, spoiling it in the shaping process. LIR, however, eliminates this problem. To that end, LIR is particularly appropriate for tires that require high performance.
