ISOPRENE RUBBER
Description: IR is a solution polymerized polyisoprene rubber with high cis-1, 4 content and a high molecular weight, which is very similar to natural rubber in molecular and micro structure. It is characterized by light color, uniformity and low level of impurities. Good flow property brings great improvement in mixing and molding.

Application: By adding value through creating unique features, IR can not only be used in the traditional fields that NR usually present like tires, convey belts, hoses, shoes soles etc., but also can be applied in the production which require high purity and/or well-defined molecular structure such as food and pharmaceutical package, baby bottle teats, adhesive, light color or transparent articles.
Package: IR is supplied in bales weighing 25.0±0.25kg (size: L: 65cm W: 35cm H: 15cm).Bales are wrapped in linear low-density polyethylene (LLDPE) film and packed in (PP) plastic and paper compound bags.
Storage: IR should be stored in ventilating warehouses at temperature not higher than 30°C, away from heat and fire sources, direct sunray, atmosphere precipitation and contamination. Shelf life could be two years from the manufacturing date under the correct storage conditions.
