Science and Expertise
This process ensures exceptional product quality with minimum property variation. The Safron® grades produced using this technology include homopolymers, random copolymers and impact copolymers. The Spheripol production process is environmentally friendly, producing no undesired by-products during the manufacturing process.
The Hostalen process is the polymerisation of ethylene in suspension in a hydrocarbon diluent. With the slurry process there is a tendency to make higher molecular weights but also to tailor the molecular weight distribution, as a result grades produced using this technology perform very well in blow moulding, pipe extrusion and film applications. The Hostalen process is still one of the most mature, flexible, versatile and widely used processes. A technology agreement with LyondellBasell permits for technology advancement to satisfy changing market needs.
The Continuous Polymerisation part of the process is in collaboration with technology partner Invista. The Solid State Polymerisation is in collaboration with engineering partner Polymetrix (Bühler).
This technology partnership allows for excellent environmental performance and high product quality that is recognised throughout the industry.
