Kuraray Liquid Rubber

Kuraray Liquid Rubber (LIR) is a viscous rubber additive that is used in kneading and cross-linking rubber when shaping and processing. LIR works as a reactive plasticizer and can replace the natural mineral oil present in rubber, reducing oozing and spoiling in the shaping and molding process.
