High Impact Polystyrene [HIPS]

High Impact polystyrene [HIPS] is an inexpensive, lightweight plastic sheet that is available in various colours with a gloss, matt or embossed surface finish. High Impact Polystyrene can be fabricated and is easily thermoformed and is typically used for handling-trays which accommodate lightweight product. Unmodified grades have poor UV resistance and should not be used for external applications. HIPS offers a consistent, easily printed matte surface for either one or two sided printing applications. This polystyrene sheet product, is especially suitable for Lithographic or Flexographic printing of displays, POP graphics, signs, tags and cards. However HIPS has a poor fire performance and this should be taken into consideration when assessing it's suitability for display applications.
