Production Process

The Butyl scrap is collected from a network of approved suppliers and is further segregated to ensure only the Butyl material is taken for reclaiming. The entire process is divided into two phases. In the first phase, the scrap is passed through a number of stages to ensure that it is free of contaminants.

In second phase the material is depolymerized and filtered with screens from 60 to 100 Mesh for metal impurities through straining and then further refined for crushing the rubber granules by the means of refining process with high quality rubber refiners to get the original depolymerized Natural reclaim rubber at the end.
