Polystyrene Sulzer to Execute Contract for EPS Production Plant in Brazil

Sulzer has received an order from Innova for the delivery of a foam production system relying on Sulzer's extruder-based melt impregnation technology. The facility in Triunfo, Brazil, will produce Expandable Polystyrene (EPS). Commercial production is planned to start mid-2016.

Winterthur/Switzerland – The facility has a capacity for EPS of more than 24,000 t/a. The polystyrene is suitable for a broad range of applications, including state-of-the-art insulation material for the South American market.

Sulzer´s division Chemtech technology portfolio for EPS production includes both melt feed technology with raw material taken directly from a polystyrene reactor and extruder-based technology for use of solid resin pellets. The recent acquisition of the German company Aixfotec has strengthened particularly the extruder-based technology.

High-End Insulation Materials

Both technologies offer precise blowing agent dosing, temperature control, low shear, narrow bead size distribution as well as mixing and dispersing of blowing agent and additives. While offering high flexibility to process different feed materials and recycling streams, Sulzer’s standalone extrusion system is particularly suitable for producing high-end insulation materials requiring precise control of key process parameters. Over the past ten years, Sulzer has developed formulations for production of insulation grade EPS requiring the addition of thermal non-conductive fillers and flame retardants.

Biggest Producer of Styrene Monomer in Brazil

Videolar-Innova is the first and only petrochemical company in Brazil to integrate the production units for ethylbenzene, toluene, styrene monomer and polystyrene in a single industrial plant. The newly formed company is the biggest producer of styrene monomer and polystyrene in Brazil. With Sulzer’s support, Videolar-Innova will enter the South American insulation market. The company will provide the strategic downstream integration with unique production capabilities, in a region which is still importing most of its consumed EPS.
