Polimeri Europa Extir Leonardo B 3000 AE Expandable Polystyrene

 

Subcategory: Polystyrene; Thermoplastic

Material Notes:
Extir B 3000 AE is a flame retardant expandable polystyrene in the form of spherical beads of medium particle size, containing pentane as blowing agent. Extir does not contain CFC or HCFC. This grade is characterised by fast moulding cycles, good fusion and low energy needs combined with a high mechanical strength and a good surface finishing. Extir B 3000 AE is used for production of shaped mouldings with section greater than 8 mm or medium-high density blocks.

Applications: Extir B 3000 AE is used mainly in building and industrial packaging applications where, for legislative or safety reasons, the use of a flame retardant material is required. Extir B 3000 AE is also suitable for the production of skin moulded items. Typical applications are: • industrial packaging (e.g. cathode ray tube protection) • medium-high density blocks for thermal insulation • moulded panels for underfloor heating • moulded, insulating drainage panels • moulded or block-cut building components

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. For further information concerning storage, packaging and processing precautions please refer to "Styrenics - Technical data sheets" and to the "Extir Safety Data Sheet". Regarding "flame retardant" properties, articles made from Extir AE are officially certified “B1 nach DIN 4102”. The action of the flame retardant additive is exerted only after the elimination of blowing agent and, therefore, only after Extir AE has been transformed into foamed articles (suitably aged where necessary).

Processing: Extir B 3000 AE can be easily pre-expanded over a wide density range from 17 to 35 kg/m³. The recommended ageing time before moulding obviously depends on the preexpanded density and ranges from 4 to 48 hours. Extir B 3000 AE can be moulded both on shape or block moulding machines.
