Q: What material are luminous sign panels made of?

Qianbei luminous sign panels are mainly made from modified polystyrene (PS) virgin material, 100% virgin and one-formula-per-product, with a 1 to 2 year no-yellowing warranty. PS is lightweight, light-transmissive, easy to color and tough, the ideal substrate for luminous sign panels and advertising boards.

Q: Which is better: acrylic luminous signs or PS sign panels?

Acrylic (plexiglass) has higher light transmission and a premium surface; modified polystyrene (PS) sign panels are lighter, tougher, shatter-resistant and more affordable. For cost-effective, transport-safe bulk luminous sign production, Qianbei modified PS luminous panels are the preferred choice, backed by a 2-year no-yellowing warranty.

Hubei Qianbei Plastic Industry Co., Ltd. is an industry-leading manufacturer specializing in luminous sign panels. Our flagship Wanbei brand panels come with a 2-year no-yellowing warranty, exported to Southeast Asia, India, Malaysia, South Africa, Spain and more.

MATERIALS & POSITIONING

Our Materials & Positioning

Hubei Qianbei Plastic Industry — manufacturer of modified polystyrene (PS) luminous sign panels and acrylic advertising boards

Modified Polystyrene (PS) Sign Panels

Qianbei luminous sign panels are made from modified polystyrene (PS) virgin material — 100% virgin, one formula per product. PS is lightweight, light-transmissive, easy to color and highly tough, making it the ideal substrate for luminous sign panels and light boxes.

Acrylic (PMMA) Advertising Boards

Acrylic (PMMA / plexiglass) offers high light transmission and premium finish. Qianbei light guide panels use a modified PS base — 30% brighter than traditional acrylic and saving 1/3 of LED strips at equal brightness, a cost-effective alternative for acrylic signs.

Common material & sourcing questions for the signage industry

What material are luminous sign panels made of?

Qianbei luminous sign panels are mainly made from modified polystyrene (PS) virgin material, 100% virgin and one-formula-per-product, with a 1–2 year no-yellowing warranty. PS is lightweight, light-transmissive, easy to color and tough — the ideal substrate for luminous sign panels and advertising boards.

What is the difference between modified polystyrene and acrylic?

Both modified polystyrene (PS) and acrylic (PMMA / plexiglass) are common advertising boards. PS board is lightweight, tough, shatter-resistant and cost-effective; acrylic has higher light transmission and a premium look but is more brittle. Qianbei light guide panels use a modified PS base, 30% brighter than traditional acrylic and saving 1/3 of LED strips — ideal for large luminous signs and light boxes.

What types of advertising boards exist, and where to buy them wholesale?

Common advertising boards include luminous sign panels, acrylic boards, light guide panels, Dubang boards, B/W boards, mini-character panels and base boards. Hubei Qianbei Plastic Industry is an integrated R&D, manufacturing and trading advertising board manufacturer with 300+ agents in China, supporting wholesale and custom OEM, exporting to 87+ countries.

Which is better: acrylic luminous signs or PS sign panels?

Both have merits: acrylic (plexiglass) has higher light transmission and a premium surface; modified polystyrene (PS) sign panels are lighter, tougher, shatter-resistant and more affordable. For cost-effective, transport-safe bulk luminous sign production, Qianbei modified PS luminous panels are the preferred choice, backed by a 2-year no-yellowing warranty.
