Jackon JACKOCELL® R311 Expanded Polystyrene Packaging and Shape Molding
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)
Material Notes:	100% Polystyrene. Pre-expansion High density stability in pre-expansion, transportation and silo storage reduces opportunity losses through achieving typical lower average density during regular production. It is the unique design of polystyrene chains that gives the high strength advantages to Jackocell® R311 in pre-expansion Shape Moulding Fast molding cycles, good fusion, and easy to reach good surface. The additional broad moulding window further reduces waste material and maintains a high quality to the extent that it can be recognized long term on productivity and financial earnings.
