The vast majority of natural and synthetic rubbers, so suitable for production of adhesives and coatings, are, in their original state, unusable. In order to be able to use these polymers, compounding must be carried out. Large lumps of raw rubber must normally be milled to impart the required degree of plasticity. Plasticity of the rubber will, particularly with natural rubbers, affect the ultimate viscosity and adhesion of a solution at a given solids content.

Once milled the polymer must be granulated, to facilitate easy dissolving in solvent, and be dusted to prevent "blocking", where the rubber, if not coated with a suitable dusting compound, would re-coagulate into lumps once again. Chemipat has enviable milling facilities, ensuring customers of the ability to cope with even the largest bulk orders. Homogeneity of compound, and freedom from contamination by hard lumps of unmilled compound is assured by the facility to Barwell semi-finished compound, prior to granulation.

Wet-mixing of Chemipat or customer produced compound, involves converting the polymer compound into solution. This is performed to strict tolerances in our well-equipped wet-mixing facility. All stages of the production process are certified to ISO EN 9002, and the customer can be assured of quality product delivered on time, every time.
