What thickness and size ranges can you produce for polystyrene sheets?

We offer customizable thickness from 0.7 mm to 3 mm, or customized size according to your specifications. Polystyrene sheets can be provided in cut-to-size panels or roll forms (for thin gauges under 1.5 mm).

Do you provide custom colors and surface finishes?

Yes. We support Pantone / RAL color matching for polystyrene sheets. Surface finishes include glossy, matte, smooth, and textured/embossed such as sand, leather, or diamond patterns.

Can your HIPS sheets be used for vacuum forming and printing?

Yes. Our HIPS sheets are specifically engineered for vacuum forming, pressure forming, and thermoforming. They feature excellent draw ratios and high detail accuracy. Our sheets also accept corona treatment for superior ink adhesion in UV printing, screen printing, and digital printing.

What is the standard lead time for polystyrene sheets?

In-stock items ship in 37 days. Custom or bulk orders take about 15 days in the off-season and about 30 days in peak season.

What is your MOQ for polystyrene sheets?

Our MOQ for polystyrene sheets is 500 kg per item. Mixed thicknesses can be combined in one order.

Can you provide free samples for testing?

Material samples are free. The customer pays the shipping cost, which is deducted from your first order.

What is the difference between HIPS and GPPS sheets?

HIPS sheets incorporate rubber components, offering high impact resistance and good toughness, and they are opaque and exceptionally well-suited for thermoforming. GPPS sheets are rigid and highly transparent (with high light transmission), often used as a substitute for glass or for optical panels.

Product Categories (HIPS & GPPS Sheets)

To meet the specialized requirements of diverse industrial clients, our polystyrene sheets are categorized into two core segments.

HIPS Sheet

Product Features: Modified with synthetic rubber, HIPS sheets offer exceptional impact strength, superior toughness, and excellent deep-draw thermoforming capabilities, ensuring resistance to cracking during the vacuum-forming process.

Typical Applications: Anti-static blister trays for electronic components, food packaging containers, refrigerator liners, advertising signage, and toy casings.

GPPS Sheet

Product Features: Characterized by crystal-clear transparency (with light transmission reaching over 90%), high hardness, and high rigidity, the cost-effective GPPS sheets serve as an ideal, lightweight alternative to glass.

Typical Applications: Protective panels for picture or photo frames, shower enclosures, LED lighting diffuser panels, disposable tableware, and display cases.
