0.5mm 1mm 2mm HIPS Sheet for Thermoforming

0.5mm, 1mm & 2mm HIPS Sheet for Thermoforming

HSQY 0.5mm, 1mm and 2mm HIPS sheets combine impact resistance, rigidity and reliable thermoforming performance for packaging trays, displays, appliance parts, covers and other vacuum-formed components.

High Impact Polystyrene, commonly known as HIPS, is a rubber-modified polystyrene material developed to provide greater toughness than standard GPPS while retaining good forming, printing and fabrication performance.

This page focuses on three commonly requested gauges: 0.5mm for lightweight formed parts, 1mm for general-purpose thermoforming and displays, and 2mm for larger or more rigid formed components. HSQY's broader HIPS range covers approximately 0.2mm to 6mm with widths up to 1600mm.

HIPS Sheet Specifications

Thickness Selection Note: 0.5mm, 1mm and 2mm are starting-sheet thicknesses. Final wall thickness after thermoforming depends on draw depth, mold geometry and material distribution, so finished-part requirements should be considered when selecting the starting gauge.

How to Choose 0.5mm, 1mm or 2mm HIPS Sheet

Sheet thickness directly affects rigidity, forming depth, material usage and the wall thickness of the finished component. The correct gauge should therefore be selected according to part dimensions and forming geometry rather than simply choosing the thickest material.

These are general selection directions, not guaranteed application limits. A large shallow part may use a different gauge from a small deep-draw part. Forming trials should confirm the final specification.

0.5mm HIPS Sheet

0.5mm HIPS is a thin-gauge material suitable for lightweight thermoformed components where low material usage and easy forming are important. Typical applications can include shallow packaging trays, product inserts, disposable or lightweight components and small display parts.

Because 0.5mm material can thin significantly during deep forming, buyers should pay particular attention to corner thickness, webbing and the minimum wall thickness required in the finished part.

1mm HIPS Sheet

1mm HIPS is a versatile general-purpose gauge for vacuum forming, thermoforming, printing and fabrication. It provides more rigidity than thin 0.5mm material while remaining suitable for many forming applications.

This thickness can be considered for display components, signs, trays, covers, prototypes and medium-size formed products, subject to part geometry and performance requirements.

2mm HIPS Sheet

2mm HIPS provides greater initial rigidity and more material for forming than 0.5mm or 1mm sheet. It can be useful for larger thermoformed products, equipment covers, appliance parts, liners and fabricated panels.

A thicker starting sheet does not automatically guarantee sufficient finished-part strength. Deep forming can still reduce wall thickness around corners and sidewalls, so critical areas should be measured on the formed component.

Why HIPS Is Used for Thermoforming

HIPS is widely used for thermoforming because suitable grades offer a practical balance of formability, rigidity, impact resistance and material cost. The rubber-modified structure provides improved toughness compared with standard GPPS.

During thermoforming, the sheet is heated until sufficiently pliable and formed against a mold using vacuum, pressure or mechanical assistance. The final result depends on the material grade, sheet thickness, heating profile, mold design and forming cycle.

HIPS Sheet for Vacuum Forming

Vacuum forming uses a pressure difference to pull heated HIPS sheet over or into a mold. It is commonly used for trays, packaging inserts, housings, covers, liners, display components and prototype parts.

For repeatable production, buyers should evaluate mold definition, shrinkage, webbing, trimming behavior and final wall thickness using the exact HIPS grade and thickness intended for mass production.

Key Benefits of HIPS Sheet

• Improved impact resistance: Rubber modification improves toughness compared with standard general-purpose polystyrene.

• Good thermoformability: Suitable HIPS grades can be vacuum formed and thermoformed into a wide range of three-dimensional parts.

• Good dimensional stability: Useful for fabricated and formed applications when the correct grade and process are selected.

• Lightweight and rigid: HIPS provides useful stiffness without excessive material weight.

• Smooth surface: Suitable grades can support printing, painting, labeling and lamination.

• Easy fabrication: HIPS can be cut, drilled, routed, die cut and CNC machined using suitable tools.

• Color options: White, black, colored and customized sheets are available according to the selected specification.

• Broad gauge range: HSQY's current product family covers approximately 0.2mm to 6mm.

HIPS Sheet for Packaging Trays & Inserts

Thin and medium-gauge HIPS can be used for protective trays, inserts, clamshell-style components and other thermoformed packaging parts.

0.5mm may suit lightweight shallow trays, while 1mm and 2mm provide progressively more starting rigidity and material for larger or deeper products. The exact gauge should be confirmed by forming trials.

For food, medical, pharmaceutical or electronic packaging, specify the required application-specific material, static-control or regulatory requirements rather than assuming a standard HIPS grade is suitable.

HIPS Sheet for Displays & Signage

HIPS is also used for retail displays, POP/POS components, advertising panels and signage because it provides a lightweight rigid substrate that can be printed and fabricated.

For flat printed graphics, sheet thickness should be selected according to panel size, mounting method and required stiffness. Printing compatibility depends on surface finish, ink system and any required surface treatment.

HIPS Sheet for Appliance Parts & Liners

HIPS can be evaluated for appliance liners, covers, housings and interior components where thermoforming performance, rigidity, surface appearance and impact resistance are required.

For appliance projects, specify operating temperature, chemical or detergent exposure, forming depth, color, surface finish and required mechanical performance so the correct HIPS grade and thickness can be evaluated.

HIPS Sheet for Covers, Housings & Prototypes

HIPS is easy to cut and fabricate, making it useful for equipment covers, prototype enclosures, models, mock-ups and short-run fabricated components.

1mm material can be useful for lightweight models and formed covers, while 2mm material provides greater flat-sheet stiffness for larger panels or prototypes. Mechanical requirements should still be checked on the finished component.

Cutting, Machining & Fabrication

HIPS can be fabricated using suitable cutting, drilling, routing, punching, die-cutting and CNC processes. Processing conditions should be selected according to sheet thickness and part geometry.

For thin 0.5mm sheet, adequate support helps reduce flexing during cutting. For 1mm and 2mm material, tool geometry, feed rate and heat generation should be controlled to maintain clean edges and accurate dimensions.

Printing, Painting & Lamination

Suitable HIPS surfaces can be printed, painted, labeled or laminated for displays, graphics, branded products and decorative components.

Printing and bonding performance depends on surface condition, ink or adhesive chemistry and any required surface treatment. Test the actual HIPS grade before large production runs.

Indoor & Outdoor Use

Standard HIPS is primarily used for indoor and controlled applications unless the exact grade has been specifically formulated and tested for extended outdoor weathering.

For continuous sunlight exposure, specify UV resistance, weathering conditions and required service life so an appropriate stabilized grade or alternative material can be considered.
