Q&A

Q

What is Polystyrene (PS) sheet and why is it used?

Polystyrene (PS) sheet is a lightweight, rigid thermoplastic with good dimensional stability and ease of fabrication. It is widely used in industrial, signage, packaging, display, and architectural applications due to its smooth surface, ease of cutting, engraving, and shaping, and its cost-effectiveness compared to other plastics like PC or acrylic.

Q

What colors and finishes are available for PS sheets?

PS sheets come in transparent, clear, white, black, blue, green, and other custom colors. Surface finishes include smooth, matte, textured, and embossed. Special options like hard-coated (scratch-resistant) or glossy surfaces are available depending on your application.

Q

What are the standard sizes and thicknesses of PS sheets?

Standard sizes include 1220mm×2440mmand1000mm×2000mm, with custom sizes available. Thickness typically ranges from 0.5mm to 40 mm, and thicker sheets can be produced for structural or heavy-duty applications.

Q

What are the thermal properties of PS sheets?

Polystyrene sheets have a continuous operating temperature range of –20°C to +80°C and can tolerate short-term exposure up to +95°C. They maintain dimensional stability and rigidity under normal operating conditions.

Q

Can PS sheets be fabricated or customized?

Yes, PS sheets are easy to cut, drill, engrave, thermoform, bend, and assemble. They are commonly fabricated into signage, display cases, protective panels, packaging, and decorative components. Edge finishing, engraving, or printing (screen or UV) can also be applied for branding or signage purposes.

Q

Are PS sheets suitable for food contact?

Food-grade PS sheets are available and compliant with relevant safety standards. They are non-toxic, hygienic, and easy to clean, suitable for food trays, packaging, and display cases.

Q

How durable are PS sheets compared to other plastics?

PS sheets are rigid but brittle compared to PC, meaning they are easily cut and shaped but less impact-resistant. They are ideal for applications where lightweight, smooth surfaces, and cost-effectiveness are prioritized over high impact strength.

Q

What industries commonly use PS sheets?

1.Industrial & Fabrication: panels, protective covers, machine guards

2.Signage & Display: signs, advertising panels, exhibition displays

3.Packaging: trays, boxes, inserts

4.Architectural & Decorative: partitions, interior panels, decorative elements

5.Food & Retail: food trays, display cases, protective coverings

Q

How durable are PS sheets compared to other plastics?

-PS sheets are rigid and lightweight, offering good stiffness for structural or decorative panels

-They have moderate impact resistance, lower than PC or acrylic sheets

-Not ideal for heavy-duty or high-impact applications; suitable for light-duty, indoor, or protected environments

Q

Can PS sheets be combined with other materials?

Yes, PS sheets can be laminated or assembled with other plastics, metals, or glass depending on the application, such as for display panels, signage, or packaging structures.

Q

Do you support OEM/ODM cooperation?

Yes, we support OEM and ODM cooperation mode. If you have private label or design requirements, we can produce and package according to your requirements.
