A selection of the most commonly used custom thermoforming materials are listed below.
ABS (Acrylonitrile Butadiene Styrene): Very common material. Good stiffness and impact strength. Available in a wide variety of colors and several textures. Available in UL94-V0 grades (Flame Retardant).
ACRYLIC (PMMA – Polymethyl Methacrylate, Plexiglass): Water clear and abrasion resistant material. Easily fabricated. Available in impact modified grades. Many colors available.
HDPE (High Density Polyethylene): Excellent impact and chemical resistance. Good cold temperature properties. Dimensionally not as stable as other materials.
HIPS (High Impact Polystyrene): Low cost, forms easily. Available in many colors. More brittle than ABS.
KYDEX (PMMA / PVC blend): Good general-purpose material, offering excellent impact and chemical resistance in a highly cosmetic sheet. Most grades are flame retardant to UL94-V0. Available in many colors and textures.
PC (Polycarbonate): Very high impact strength. Clear. High temperature resistance.
PEI (Polyetherimide, Ultem): Very high temperature grade material. Autoclavable. Natural amber color.
PETG (Polyethylene Terephthalate Glycol): Clear, with excellent impact strength. Forms well.
PP (Polypropylene): Excellent chemical resistance. Rigid, with very good impact strength. Good at higher temperatures. But dimensionally not as stable as other materials, similar to HDPE.
PVC (Polyvinyl Chloride): Rigid material. Very good impact strength. Flame retardant. Limited availability.
TPO (Thermoplastic Polyolefin): Outstanding impact properties. Available with a high gloss finish. Good for outdoors applications. More difficult to form, especially deep draw shapes.
