Polycarbonate Coloured Granules Properties, Uses, and Applications
                     Polycarbonate Coloured 
Granules: Properties, Uses, 
And Applications
What Are Polycarbonate Coloured 
Granules?
Polycarbonate coloured granules are small, solid pellets 
of polycarbonate polymer that have been mixed with 
pigments or dyes to impart specific colours to the 
material. Polycarbonate itself is a transparent, rigid 
plastic with excellent mechanical properties, heat 
resistance, and optical clarity. When coloured, these 
granules retain the base material’s strengths, while 
providing vibrant colour options that enhance the visual 
appeal of the finished product. Common colour variants 
include PC Black, PC Grey, PC Red, PC Amber, PC 
Smoke, and PC Blue.
Key Properties of Polycarbonate Coloured Granules
Polycarbonate, as a base material, offers several superior characteristics that are retained in its 
coloured form. These properties make polycarbonate coloured granules a sought-after material in many 
industries.
• Impact Resistance
• Transparency and Clarity
• Thermal Stability
• UV Resistance
• Electrical Insulation
• Chemical Resistance
• Design Flexibility
• Dimensional Stability
Manufacturing Process of Polycarbonate Coloured Granules
The production of polycarbonate coloured granules begins with the polymerization of bisphenol A (BPA) and 
phosgene (COCl₂), which forms the polycarbonate resin. Once the polycarbonate resin is prepared, it is 
combined with specific colourants (either pigments or dyes) to produce coloured granules.
The key steps in the production of polycarbonate coloured granules are:
• Preparation of Masterbatch
• Incorporation of Masterbatch into Polycarbonate Resin
• Pelletization
• Quality Control
Applications of Polycarbonate Coloured 
Granules
1. Automotive Industry:
• Headlamp lenses
• Interior components
• Exterior trim
2. Consumer Electronics
Polycarbonate coloured granules are frequently used in the consumer 
electronics industry for enclosures, housings, and covers. These 
include products like:
• Smartphone and tablet housings
• Laptop covers
• LED light covers
• Computer peripherals
3. Packaging Industry
Polycarbonate coloured granules are also used in the packaging industry for producing high-
strength, visually appealing packaging products. Examples include:
• Clear and coloured bottles
• Packaging films
4. Signage and Display
Polycarbonate coloured granules are often used in signage and display products, thanks to 
their excellent clarity and UV resistance. Applications include:
• Outdoor signs
• Point-of-purchase displays
5. Medical Devices
In medical applications, polycarbonate coloured granules are used for producing components 
that require clarity, strength, and biocompatibility, such as:
• Medical instrument housings
• Diagnostic equipment
• Drug delivery devices
Advantages of Polycarbonate Coloured Granules:
The key advantages of using polycarbonate coloured granules include:
• High Strength
• Design Flexibility
• Durability
• Transparency
Conclusion
Polycarbonate coloured granules provide a versatile solution for manufacturers who need a 
combination of strength, clarity, and aesthetic appeal in their products. With applications 
spanning multiple industries, from automotive and consumer electronics to medical devices 
and signage, polycarbonate coloured granules offer a unique balance of mechanical properties 
and design flexibility. As demand for high-performance, visually appealing products continues 
to grow, polycarbonate coloured granules will remain an essential material in modern 
manufacturing.
