Polycarbonate Injection Moulding: Material Properties & Applications

Polycarbonate, abbreviated as PC, is a tough, high-performance thermoplastic known for its outstanding impact resistance, optical clarity, and heat resistance. Polycarbonate injection moulding is often chosen where strength and transparency are both required, making it ideal for demanding applications across automotive, electrical, medical, and consumer products.

At Great Central Plastics, polycarbonate injection moulded components are used in applications that must withstand physical stress, high temperatures, or repeated use, while still meeting aesthetic and dimensional requirements.

History

Polycarbonate was first developed in the 1950s and commercialised soon after by Bayer and General Electric. It quickly became known for its durability and glass-like clarity, leading to widespread adoption in engineering, medical, and safety-critical industries. It remains one of the most trusted engineering plastics in injection moulding today.

Material Properties

Polycarbonate is an amorphous thermoplastic that combines exceptional toughness with high transparency. These properties make it one of the preferred materials for injection moulding applications requiring both performance and clarity. It can be used in clear, tinted, or opaque grades and is often selected for applications demanding performance over cost.

Common Polycarbonate Injection Moulding Applications

Polycarbonate injection moulding is used extensively in applications where strength, clarity, and temperature resistance are essential. At Great Central Plastics, our polycarbonate injection moulded components include:

• Protective covers and safety guards

• LED light housings and diffusers

• Automotive components and interior trim

• Transparent machine housings

• Consumer electronics casings

• Reusable drinkware and food containers

• Industrial and branded products requiring extreme durability

• DVDs, CDs and Blu-ray discs

• Greenhouse panels, roofing, glazing and facades

• Safety goggles, face shields and other protective barriers and equipment

If your product needs to combine aesthetics with resilience and heat resistance, polycarbonate injection moulding is often the material choice.

Alternative Names & Abbreviations

• PC (Polycarbonate)

• Common trade names include: Makrolon®, Lexan®, Panlite®

• Sometimes referred to as engineering plastic or clear engineering plastic

• Sometimes mentioned by its properties, such as ‘clear scratch-resistant plastic,’ ‘impact-resistant plastic’ or ‘heat-resistant clear plastic’

Sustainability & Recycling

Polycarbonate is recyclable, typically under resin code #7, but it is less commonly recycled through household collection schemes. Nonetheless, its long lifespan and reusability make it a good candidate for sustainable moulding in durable or reusable products.

Polycarbonate injection moulded parts can be reground and reprocessed in appropriate applications. At Great Central Plastics, we help our customers make informed material choices, including when polycarbonate can deliver better lifecycle efficiency than more disposable options. Our goal is always to support eco-friendly plastic manufacturing through smarter design and material selection.

Colours, Textures & Finish Options

Polycarbonate is naturally transparent but can also be supplied in tinted or opaque colours. It delivers excellent results in glossy or smooth finishes, and certain grades offer UV resistance, flame retardancy, or anti-scratch coatings.

This makes polycarbonate injection moulding highly versatile for both technical and decorative applications, especially where strength and visual quality are equally important.

Suitability for Secondary Processes

Polycarbonate injection moulded components are highly adaptable in post-mould processing, with good compatibility for:

• Ultrasonic welding

• Pad printing and laser engraving

• Painting and coating

• Hot foil stamping

• Mechanical assembly

These processes enable Great Central Plastics to produce ready-to-use components for safety equipment, branded merchandise, and high-specification assemblies.
