| Polycasa PETG is the brand name for extruded Polyethyleneterephthalate Glycol (PETG) copolyester sheet from Polycasa. As a result of the extrusion process, Polycasa can offer, in addition to clear and opal versions, a variety of colours and designs to suit a wide range of requirements. Polycasa PETG meets all current food contact legislation and can be used in contact with unwrapped food. Our UV Grade is not intended for food contact and is therefore not covered by this warranty. CHARACTERISTICS Good optical properties. Brilliant surface. Easy to fabricate. Its biggest advantage compared to other plastics is in vacuum forming. Exceptional low temperature performance. Very good chemical resistance. Very high impact properties. Low water absorption. Easy to recycle. APPLICATIONS Bus shelters. Poster glazing. Machine guards. Medical appliance packaging. Displays & signs for external use. Refrigerators and cold storeroom equipment. Bicycle safety helmets. Food containers. Lenticular lenses. Graphic arts. Lighting controllers for hazardous areas. Motorcycle windshields.&& |
