Polycasa PETG是Polycasa挤出聚对苯二甲酸乙二醇酯(PETG)共聚酯片材的品牌名称。由于采用挤压工艺,Polycasa除了提供透明和蛋白石版本外,还可以提供各种颜色和设计,以满足广泛的要求。Polycasa PETG符合所有现行的食品接触法规,可用于接触未包装食品。我们的紫外线等级不适用于食品接触,因此不在本保修范围内。具有良好的光学性能。明亮的表面。易于制造。与其他塑料相比,它最大的优点是真空成型。卓越的低温性能。很好的耐化学性。非常高的冲击性能。吸水率低。易于回收利用。应用巴士候车亭。海报玻璃。机器防护装置。医疗器械包装。供外部使用的显示器和标志。冰箱和冷藏室设备。自行车安全帽。食品容器。透镜状镜片。图形艺术。危险区域照明控制器。摩托车挡风玻璃。 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. |
