Symbol according to ISO 1043-1: (PS-I + PE)

Special polystyrene alloy which combines the easy processing of styrenics with superior impact strength and excellent environmental stress cracking resistance to chemicals, oils and fatty foods.

Koblend P 477E is recommended for the extrusion and the thermoforming of sheets for industrial applications, for inner liners of refrigerators and packaging for fatty foods.

Applications:

Thermoformed panels for tractors, inner liner for refrigerators where HCFC 141b is used as blowing agent for the insulating PU foam, tubs and lids for packaging of fatty foods such as margarine, salads etc.
