SINTREX®: The Next-Generation Lightweight Rigid PET Sheet for Sustainable Print and Display

In today's visual communications market, customers are increasingly looking for materials that offer high performance without compromising on sustainability. As the industry shifts away from traditional PVC and foam substrates, demand continues to grow for products that deliver durability, print quality, and recyclability in equal measure.

SINTREX®, the latest innovation from 3A Composites, has been developed to meet exactly that need — and is now available exclusively through Pyramid Display Materials in the UK.

SINTREX® is a lightweight rigid PET sheet designed for versatile print, fabrication, and display applications. Manufactured with a focus on material performance and environmental responsibility, SINTREX® provides a robust, stable platform suitable for both short-term and more durable indoor and outdoor signage.

Key Benefits and Performance Advantages

Performance Highlights:
• Lightweight yet rigid construction
• Excellent fire performance (ideal for public and retail spaces)
• Good recyclability, supporting more sustainable material choices
• Stable surface for high-quality print output
• Easy to cut, route and shape using standard workshop equipment

This balance of characteristics makes SINTREX® a compelling alternative to commonly used rigid substrates such as Foamex, PVC sheets, polypropylene boards and fluted polypropylene display panels.

Where SINTREX® Works Best

SINTREX® is designed for direct digital printing, screen printing and vinyl application, making it suitable for a wide range of display environments, including:

• Retail and POS displays
• Internal signage systems
• Exhibition graphics and event structures
• Hoardings and construction displays
• Directional and wayfinding signage

Its rigid PET composition ensures excellent edge stability and reduced warping, particularly in environments where temperature or moisture changes could affect dimensional integrity.

Where SINTREX® Works Best

With growing expectations around responsible material selection, many brands and print providers are actively transitioning toward PVC-free solutions.

SINTREX® supports this transition.
• It is recyclable through standard PET material recovery streams.
• It reduces reliance on PVC substrates without compromising performance.

This not only improves sustainability credentials but also strengthens your offering when responding to environmentally-led tenders or eco-conscious clients.
