HIPS Sheet Sizes Overview
Choosing the right HIPS sheet size is essential for any project. Sheet size affects how materials fit into production lines, how much waste is generated, and how easy they are to handle. Sunplas offers a wide range of HIPS sheets to meet different needs, from standard industry sizes to fully customized options.
Standard Sizes
Many industries rely on standard HIPS sheet sizes for efficient planning and production. The most common standard size is 48 inches by 96 inches, widely compatible with manufacturing equipment and easy to transport and store. Standard sheets are frequently used in retail displays, appliance liners, and signage.
Sunplas provides HIPS sheets in these standard dimensions with thicknesses typically ranging from 0.020" to 0.250", covering most general applications. Standard sizes help reduce lead times and simplify ordering for customers needing quick turnaround.
Custom Sizes
Some projects require HIPS sheets beyond standard dimensions. Sunplas stands out by offering custom sizes up to 1,900 mm wide with no limit on length — going beyond what many other suppliers can provide. Custom sheets are especially useful for large-scale displays, unique product housings, or specialized industrial parts, available in thicknesses from 0.5 mm to 6 mm.
| Feature | Standard Size | Custom Size Options |
|---|---|---|
| Width | 48" (1,220 mm) | Up to 1,900 mm |
| Length | 96" (2,440 mm) | Unlimited |
| Thickness Range | 0.020"–0.250" (0.5–6 mm) | 0.5–6 mm |
| Format | Sheet | Sheet or Roll |
Sheet and Roll Formats
Sunplas offers HIPS sheets in both sheet and roll formats. Sheet format is ideal for manual handling, cutting, and forming; roll format suits automated processes and continuous production. Roll-format sheets can be cut to any length, making them perfect for long production runs, while sheet format provides easy stacking and storage for smaller batches.
HIPS Sheet Thicknesses
Understanding thickness is crucial for selecting the right material. Thickness affects strength, flexibility, weight, and suitability across applications — from retail displays to industrial components.1
Thickness Range
Sunplas offers HIPS sheets from 0.6 mm to 8 mm. Thinner sheets are used where flexibility is needed, while thicker sheets provide greater impact resistance and structural strength for demanding environments.
| Thickness Range (inches) | Thickness Range (mm) |
|---|---|
| 0.020″ to 0.250″ | 0.5 mm to 6 mm |
A 0.5 mm HIPS sheet suits lightweight packaging, while a 6 mm sheet is often chosen for heavy-duty parts requiring maximum impact resistance.
Thickness Selection Tips
Assess the Application: Determine if the sheet will face frequent handling, bending, or external forces. Higher impact resistance is needed for parts under stress.
Balance Flexibility and Strength: Thinner sheets offer more flexibility but less impact resistance. Thicker sheets provide better protection and durability.
Consider Processing Methods: Vacuum forming, for example, typically works best with HIPS sheets between 1 mm and 3 mm for optimal results.2
Evaluate Weight Requirements: Thicker sheets add weight, which may affect transportation or installation costs.
Consult Experts: Sunplas specialists can help you select the ideal thickness for your project.
High-Impact Polystyrene Properties
Material Features
High-impact polystyrene is created by incorporating polybutadiene rubber into general-purpose polystyrene, giving it a unique combination of toughness, processability, and affordability.3
| Property | Description |
|---|---|
| High Impact Strength | Withstands large external forces; not easy to break |
| Good Molding Performance | Processed into various shapes and sizes by different molding methods |
| Excellent Electrical Insulation | Suitable for electronic devices and electrical equipment |
Durability and Stability
HIPS resists cracking and breaking even under sudden impacts, making it valuable for packaging and consumer goods. It absorbs and spreads energy from bumps or drops and maintains dimensional stability under varying temperatures — ensuring parts fit together and perform consistently. Compared to alternatives, HIPS provides a good balance of strength and value, while ABS offers higher impact resistance and thermal stability at greater cost.
Printability and Finish
HIPS surfaces allow for excellent ink adhesion, making them ideal for screen printing and digital printing. Matte finish sheets provide the best print results, with ink adhering strongly and colors appearing bright and clear. This printability is especially valuable for retail displays and advertising panels.4
