Kuraray Liquid Rubber

Stick to it Kuraray Liquid Rubber for log lastig product solutios Kuraray Liquid Rubber (K-LR) icludes Liquid Isopree Rubber (LIR) ad Liquid Butadiee Rubber (LBR). These high-viscosity sythetic rubbers are based o isopree, butadiee ad styree. They are colorless, trasparet ad alost etirely odorless with low VOC s. Kuraray s liquid rubber grades fuctio as reactive plasticizers but have far higher olecular weight tha oral plasticizers. They are co-vulcaizable ad reduce igratio sigificatly which iproves the product s shelf life. Usig Kuraray Liquid Rubber durig the rubber copoudig phase sigificatly reduces processig tie while aitaiig the rubber copouds physical properties. This results i a product with lower processig costs. The fuctioalized grades ca be boded to a wide variety of atrices for iproved perforace. Coo applicatios iclude tires, belts, hoses ad other rubber goods. I additio, K-LR is used to produce high perforace coatigs, adhesives ad sealats. K-LR FOR TIRES K-LR FOR RUBBER APPLICATIONS K-LR FOR ADHESIVES K-LR FOR COATINGS & SEALANTS

KURARAY LIQUID RUBBER IN TIRES K-LR is a favored copoet i the productio of high perforace tires. It reduces Mooey viscosity which iiizes igratio while iprovig the processability of the rubber copoud i tires. K-LR ehaces tire perforace sigificatly by siultaeously cotrollig the balace of grip, fuel efficiecy ad wear resistace. K-LR is crosslikable for superior perforace ad loger shelf life.

Differet grades ca be processed i certai tire parts to cotribute to a log lastig high quality product. 1 Beadfiller/APEX: High hardess with excellet processability Iproved diesioal stability Better filler dispersio LIR-50, LBR-300* 5 Cushio: Ehaced surface soothess of caledered sheet Reduced extrusio teperature Better gree tackiess Iproveet of dyaic properties LIR-50, LBR-302, LBR-307 2 Side wall / Carcass: Iproved diesioal stability Ehaced surface soothess of caledered sheet Lower ill shrikage Better gree tackiess Higher productio rates LIR-50, LBR-302, LBR-307 5 4 3 Ri cushio: Good balace of processability ad physical properties Iproved abrasio resistace LIR-50, LBR-300* 1 4 Tread: Iproved dyaic ad physical proterties (taδ) Excellet abrasio resistace, wet ad ice grip Excellet extrudability LIR-50, LBR-302, LBR-307, L-SBR-820, L-SBR-841 3 2 *Developetal Grade

KURARAY LIQUID RUBBER IN RUBBER APPLICATIONS K-LR is processed i various rubber goods besides tires. Typical applicatios iclude ati-vibratio rubber copouds, feders, coveyer belts, rubber hoses ad gaskets. LIR ad LBR deliver a balaced perforace icludig loger shelf life with iial igratio.

KURARAY LIQUID RUBBER IN ADHESIVES K-LR is cooly used i adhesive applicatios such as pressure sesitive adhesives ad hot elts. The lower olecular weight grades iprove tack ad adhesive properties. The UV crosslik-able grades provide excellet flexibility, tack, low shrikage ad oisture resistace which are ideal for flexible electroic applicatios.
