Versalis Extir® LN 2000 Expandable Polystyrene
Categories: Polymer; Thermoplastic; Polystyrene (PS); Expanded Polystyrene (EPS)

Material Notes: Extir LN 2000 belongs to a new expandable product family, the Leonardo Series, with improved processing features: high expandability, high moulding productivity, wide processing area, optimal fusion and mechanical strenght, excellent item finishing. This family of products aims to join together the best properties of all the traditional products, such as the A, B and C grades. Extir LN 2000 can be used for the production of any kind of shaped mouldings with thin sections.

Applications: Extir LN 2000 is used mainly in the packaging sector. Due to its mechanical and aesthetical fetaures, added to high cycle speed, Extir LN 2000 is suitable for any application requiring strength and high productivity. It is moreover suitable for food contact. Typical applications are cheese boxes, seed trays, industrial packaging, and boxes for marbles or tiles

It is recommended to keep the product in a dry well ventilated store between 15-20°C. For product packaged in octabins the guaranteed shelf-life is one month; product in steel drums has a six months guaranteed shelf-life. During the processing of Expandable Polystyrene any sparkle or flame must be avoided and smoking should be forbidden. An adequate electrical grounding of machinery and of pneumatic transport lines is recommended This grade complies by composition with the requirements set by the main regulations for plastics intended for food contact (including the EEC directive 90/128).

Processing: Extir LN 2000 can be easily prefoamed from 17 to 30 kg/m³, it can be anyway be used at higher densities. The ageing time before moulding is typical of standard industrial practice; from 6 to 72 hours are recommended depending on the density and ambient conditions. Molding on any type of EPS machine is easy, regular and the resulting items satisfy the application needs over a wide range of steaming conditions.
