Large White High Impact Polystyrene Plastic Sheet (24'' x 48'')
High Impact Polystyrene (HIPS) is a low cost, tough plastic that is easy to thermoform and fabricate. Polystyrene is frequently used by hobbyists looking to fabricate or vacuum form custom parts, pieces and structures.
The sheet size tolerance is determined on initial sheet size and cutter width. We will try and maintain maximum cutting tolerance of no more than -0.25” or - 6 mm on length and width. The sheets may come larger if they are supplied larger by the manufacturer.
The industry standard tolerance is +- 10 % of the nominal thickness.
Decorative surfaces typically have a paper or plastic masking sheet to protect the surface . Some sheets will only have masking on the one decorative side.
Industrial sheets and forming sheets typically do not have masking and can have scuff marks and small surface scratches. All sheets are checked for surface finish and we will try and eliminate any sheets with excessive surface imperfections.
