Key Automation manufactures and exports polycarbonate stickers (German: Polycarbonat-Aufkleber) for customers in Germany. Made from high-quality plastic, polycarbonate stickers are considerably more durable than ordinary stickers.

They bond well to machines with rough or textured surfaces and are in demand in industrial equipment, control panels and medical devices. Below you will find the types, specifications, features and applications.

We offer several polycarbonate sticker types that improve performance in many industries:

• Clear Polycarbonate Stickers: Transparent and widely used because they bond to almost any industrial machine. They are more durable than many other stickers and are used for control panels and display overlays.
• Printed Polycarbonate Stickers: Custom-printed stickers with bright, detailed graphics, used for logos, warnings and instructions. They are used for safety purposes and detailed machine labelling.
• Textured Polycarbonate Stickers: Available in finishes such as matte and anti-glare. They reduce reflections under strong lighting or sunlight and improve readability.
• Embossed Polycarbonate Stickers: A raised surface gives tactile feedback on sensitive machines. They are mostly used on control panels where an accurate, instant tactile response is needed.

The specification chart below gives more details about our polycarbonate stickers:

Features	Details
Material Composition	Polycarbonate (PC) resin,
Thickness	Typically ranges from 0.125 mm to 2 mm,.
Surface Finish	gloss, matte, textured, or velvet finishes;
Adhesive Options	Permanent or removable acrylic, solvent-based, or silicone adhesives
Temperature Resistance	Operates effectively between -40°C to +130°C,
Chemical Resistance	High resistance to chemicals such as acids, solvents, oils, and alkalis
UV Resistance	UV-stabilized to prevent yellowing and degradation over time.
Dimensional Stability	Low thermal expansion coefficient, ensuring minimal warping or distortion under temperature variations.
Optical Clarity	High transparency with a light transmission rate of up to 89%, useful for applications requiring clear visibility.
Flame Retardancy	Can be treated to meet UL94 V-0 standards for flame retardancy, suitable for safety-critical environments.

To perform well in many applications, our polycarbonate stickers offer these features:

• High-Quality Printing: Our polycarbonate labels and graphic overlays are printed in high resolution, so designs are clearly visible and can be customised to your requirements. Accurate colours and detailed graphics make them easy to read.
• Scratch Resistance: Polycarbonate is naturally resistant to scratches, and a protective coating on the top surface keeps the sticker stable under frequent handling, contact with tools and rough conditions.
• Long Lasting: High-quality materials and a strong, permanent adhesive allow our polycarbonate stickers to last for years without failure.
• UV Resistance: UV-stabilised polycarbonate resists strong light exposure, so the stickers can be used outdoors.
• Self-Healing Surface: Selected polycarbonate stickers have a self-healing surface, where minor scratches or damage can disappear over time.

Their quality and flexibility make polycarbonate stickers useful in many applications. Typical examples are:

Equipment builders in Germany often need labels that meet fire-safety and substance requirements. We discuss the exact requirements before production starts.

• Flame retardancy: Materials can be treated to meet UL94 V-0, as shown in the specification table.
• Clarity: Clear versions offer light transmission of up to 89 %, which is useful for display windows.
• Compliance: RoHS-related labelling and material questions can be clarified before sample approval.
• Delivery: Export to Germany by air or sea freight, with Incoterms agreed in the quotation.
