Did you know that amber is fossilised rosin? People have used rosin for thousands of years for sealing boats and more recently in paint and the development of plastics.
Rosin, from the Latin resina, is a generic term for a secretion from conifers. Rosin consists of resin, i.e. the various saps that flow out of a tree.
Rosin has many fields of application; violinists rosin their bows with it, ballet dancers give their shoes better grip with it, and it’s used in the production of varnish and LP records.
SunPine has an annual rosin production capacity of 24,000 tonnes.
