ISOLENE® Liquid Synthetic Rubber

Product Description
The ISOLENE products are low molecular weight, liquid polymers of synthetic rubber. The chemical backbone is cis-1,4 polyisoprene. ISOLENE liquid synthetic rubber is a translucent, honey-colored liquid in bulk volume and virtually clear in thin films. It offers all the benefits of DPR liquid natural rubber without the dark color and natural impurities from natural rubber.

Typical Applications
The ISOLENE products’ color, clarity, and solubility make them ideal for compounding such products as pressure-sensitive adhesives (PSA), UV-curable polymer systems, and S-I-S & S-B-S block copolymers. The ISOLENE products are easily cross-linked with free-radical chemistry. They can be cured with ultra violet (UV) light or E-beam radiation in PSA and other photosensitive systems. Since the ISOLENE backbone is the same as natural rubber, it can be cured with conventional rubber curatives. The ISOLENE products cure into the polymer matrix and remain non-fugitive in the final product.
