The manufacturing of Airpop (EPS - expandable polystyrene) commenced in 1967. Turnover gradually grew over the years mainly because of more demand for insulation material. By 1973 a full polymerization factory was founded with a capacity of 5.000 tons of Airpop per year. To meet the requirements of the growth within the Synbra Holding this production capacity has steadily been expanded and especially over the last few years. Further growth is expected and formal requirements (environmental permits) have been acquired.
In 2011 a new step was made with the polymerization of PLA, leading to range of E-PLA BioFoam products that are since then sold complementary to its Airpop products.
In 2012 radio wave absorbing and conductive Airpop was developed.
