Jackon JACKOCELL® S314 Expanded Polystyrene Construction and Block Molding  (discontinued **)
Categories: Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)

Material Notes: Pre-Expansion

The unique design of polystyrene chains and additive chemistry in Jackocell® S314 gives pre-expanded beads high dimensional stability even at low densities, which typically reduces average operational density, providing a safe road to higher earnings. The S314 represents among the lowest density choices of all Jackocell® EPS grades.

Block Moulding

It is different from normal and regular block grades - lower densities in combination with low water absorption and high strength, however at slightly longer moulding times - makes Jackocell® S314 the favorite choice for manufacture of high quality insulation boards. It is best characterized by high heat stability, which gives substantial advantages in block moulding - such as good density control, high strength, good fusion and low scrap to secure financial opportunity losses to the end user.
