Liquid Isoprene Rubber

Kuraray Liquid Rubber

Kuraray Liquid Rubber (LIR/LBR) is a viscous rubber based on Isoprene/or butadiene, which was originally synthesized by Kuraray Co. Ltd.

LIR/LBR 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 and also eliminates blooming during product life cycle. LIR/LBR is co-vulcanizable / or co-cross linkable with solid rubbers such as NR, SBR, BR, EPDM using sulfur or peroxide. Some LIR/LBR is cross linkable by reaction of its functional group and are crossl inkable by UV radiation.

Features:

• Rubber-like properties at low temperatures

• Low viscosity improves processability

• Reduces heat generation during mixing

• Strong tackiness and adhesive properties

• Colorless, odorless, and transparent

• Co-vulcanizable characteristics

Grades:

• Homopolymer (Isoprene) : LIR-30, LIR-50
• Homopolymer (Butadiene) : LBR-305, LBR-307, LBR-352
• Isoprene/Styrene block copolymer : LIR-310
• Isoprene/Butadiene block copolymer : LIR-390
• Functional –Carboxylated : LIR-410
• Functional –Methacrylated : UC-203, UC-102
• Emulsion : LIR-700

Applications:

• Reactive plasticizer : Bead filler, Side wall, Carcass & Trade Compound for Tyre , conveyor belt, hose ,auto component

• Sealant for automobile , Construction, Electronics

• Adhesive (Hot melt & Pressure sensitive Adhesives)

• PU Modifications

• Others: Printing Plates, Coating, Lubricants etc
