Synthos EPS®/CZ types 0513FR, 0514FR 0822FR, 1640FR and 2040FR are self-extinguishing expandable polystyrene EPS with low content of pentane. The materials are formed by spherical polystyrene particles that contain a flame retardant system (content of HBCD < 0,5%) and a hydrocarbon blowing agent. Their surface is treated against gluing during processing and the formation of electrostatic charge. Due to the content of halogenated flame retardant and the residual blowing agent, the product is unsuitable for objects intended for direct contact with food.
Synthos EPS® 0513FR/CZ (Koplen 0513FR) and Synthos EPS® 0514FR/CZ (Koplen 0514FR) is mainly used for production of shaped parts with wall thickness above 10 mm (e.g. shipping packaging for glass and electrical goods, building bricks, floor and roof shaped parts); production of smaller blocks with higher density or cutted profiles.
The typical bulk density indicates values obtained during single-step pre-foaming on continuous pre-foaming devicesLower values of bulk density can be achieved only after multiple pre-expansion.
