NATURAL RUBBER COLOURED OR BLACK MASTERBATCHES
Natural Rubber has never previously been sold as Rubber Masterbatches. The introduction of this new product offers unprecedent processing facilities coupled with clean easy storage of the Masterbatch and an unlimited shelf life. For easy processing and to prevent shock load POLYMIX is packed in 35 lbs. bales, and comes with a certificate tested with the respective specifications.
Consider the following three major features:1) A very much quicker mixing cycle if premastication with peptizer is taken into account. The cycle could be reduced to 25% of the previous one.
2) Greater uniformity of the final product.
3) Cleanliness of factory in that both colored and black compounds can be produced in the same plant.
