What Is Polycarbonate (PC)?

Are you struggling to choose the right plastic material for your next project? Many engineers and product designers get overwhelmed by the numerous plastic options available. I see this confusion lead to costly mistakes and project delays almost every week.

Polycarbonate (PC) is a durable thermoplastic polymer known for its exceptional impact resistance and optical clarity. It combines high strength with lightweight properties, making it ideal for applications ranging from eyewear to electronic components.

I want to share my hands-on experience with PC material from working with hundreds of manufacturing projects. This knowledge will help you understand PC’s unique properties and whether it’s the right choice for your specific application. Let me guide you through everything you need to know about this versatile material.

Is Polycarbonate Breakable?

Have you ever worried about the durability of polycarbonate products? In today’s world, where safety and reliability are paramount, the fear of breakage in critical applications like safety glasses, automotive parts, or protective equipment can be concerning. This uncertainty becomes even more stressful when considering investments in polycarbonate materials for important projects.

While polycarbonate can break under extreme conditions, it’s one of the most durable thermoplastics available. It offers 250 times the impact resistance of glass and 30 times that of acrylic, making it highly resistant to breakage under normal use conditions.

Understanding Polycarbonate’s Physical Properties

When discussing polycarbonate’s breakability, we need to first understand its unique physical properties. The material’s exceptional strength comes from its molecular structure, which features long chains of carbonate groups¹ bonded together. This structure gives polycarbonate its remarkable combination of strength and flexibility.

Impact Resistance and Durability

Based on my experience in manufacturing polycarbonate parts at PTSMAKE, I’ve observed these impressive characteristics:

Factors Affecting Polycarbonate’s Breakability

Why Can’t Polycarbonate Be Recycled?

Every day, countless plastic products end up in landfills, and many of them are made from polycarbonate. As someone who witnesses the growing environmental concerns, I often see the frustration when people discover that their polycarbonate items can’t be easily recycled like other plastics.

The main reason polycarbonate can’t be widely recycled is its complex molecular structure and the presence of additives. These characteristics make it difficult to break down and reprocess without significant degradation in material properties. Additionally, the sorting and separation process is challenging and costly.

The Chemical Complexity of Polycarbonate

The recyclability challenge of polycarbonate begins with its molecular makeup. During my work with various plastic materials at PTSMAKE, I’ve observed that polycarbonate’s crystalline structure² poses unique challenges. Unlike simpler plastics, polycarbonate features complex polymer chains that make recycling particularly difficult.

How Much Force Does It Take To Break Polycarbonate?

I’ve noticed many clients ask about the breaking point of polycarbonate materials, especially when designing critical components. The concern isn’t just about strength – it’s about safety, reliability, and potential liability issues if the material fails unexpectedly.

Based on extensive testing and research, polycarbonate typically requires between 9,000 to 12,000 PSI (pounds per square inch) of force to break. However, this value varies significantly depending on factors like thickness, temperature, and specific grade of the material.

Understanding Polycarbonate’s Breaking Characteristics

At PTSMAKE, we frequently work with polycarbonate in various applications, from protective equipment to industrial components. The material’s tensile strength⁵ varies based on several key factors:

Is Polycarbonate Softer Than Acrylic?

When choosing between polycarbonate and acrylic for manufacturing projects, I often hear confusion about their relative hardness. This crucial material property affects durability, scratch resistance, and overall performance. Many engineers struggle to make the right choice because of conflicting information.

While polycarbonate has lower hardness ratings on both the Rockwell and Shore scales compared to acrylic, it compensates with superior impact resistance and flexibility. This unique combination makes polycarbonate more durable overall despite being technically softer.

Understanding Material Hardness Measurements

At PTSMAKE, we use several standardized methods to measure material hardness. The most common tests for plastics include the Rockwell hardness test and Shore durometer test. When examining these materials, we find that acrylic typically demonstrates higher hardness values than polycarbonate. This is due to acrylic’s more rigid molecular structure and its crystalline lattice arrangement⁶.

Comparative Hardness Values

The Impact Resistance Factor

While acrylic may be harder, polycarbonate offers exceptional impact resistance. I’ve observed that many clients initially focus solely on hardness, overlooking this crucial characteristic. Polycarbonate can absorb significant impact without breaking, making it ideal for safety equipment and high-stress applications.

Manufacturers often struggle when choosing between Polycarbonate and ABS for their projects. The decision becomes even more challenging when considering both materials offer unique advantages, and making the wrong choice could lead to project delays, increased costs, or product failures.

Based on my manufacturing experience, Polycarbonate generally costs 20-30% more than ABS but offers superior impact resistance and durability. While ABS provides good strength at a lower price point, Polycarbonate excels in applications requiring exceptional toughness and transparency.

Cost Analysis: Breaking Down the Numbers

When evaluating material costs, it’s essential to consider both raw material prices and long-term value. At PTSMAKE, we’ve observed consistent pricing patterns between these materials:

Raw Material Cost Comparison

Total Production Cost Factors

The actual cost difference goes beyond raw material prices. Mold flow analysis¹¹ shows that Polycarbonate requires higher processing temperatures and more precise control, which can increase production costs. Here’s what affects the total cost:

• Processing temperature requirements

What Surface Finishing Options Are Available For Polycarbonate Parts?

Achieving the perfect surface finish for polycarbonate parts can be challenging. Many manufacturers struggle with inconsistent results, leading to rejected parts and costly rework. I’ve seen projects delayed because teams couldn’t achieve the desired aesthetic or functional requirements for their polycarbonate components.

Surface finishing for polycarbonate parts offers multiple options including mechanical polishing, vapor polishing, coating applications, and texturing. Each method serves specific purposes, from enhancing aesthetics to improving functionality, with selection depending on the part’s end-use requirements.

Understanding Mechanical Polishing Methods

Mechanical polishing remains one of the most reliable ways to enhance polycarbonate surfaces. This process involves using progressively finer abrasives to achieve the desired finish. At PTSMAKE, we’ve refined our mechanical polishing techniques to deliver consistent results.

Multi-Stage Buffing Process

The buffing process typically follows these stages:

1. Rough buffing with coarse compounds
2. Medium buffing for smoothness
3. Final buffing for high gloss

We’ve found that maintaining proper buffing wheel speeds and pressure is crucial for preventing heat damage to the polycarbonate surface.

Chemical and Vapor Polishing Techniques

Dichloromethane¹² vapor polishing has become increasingly popular for achieving glass-like finishes on polycarbonate parts. This process momentarily softens the surface, allowing it to self-level and create an extremely smooth finish.

Safety Considerations for Chemical Processes

Safety remains our top priority when performing chemical polishing:

Coating Applications

Surface coatings can significantly enhance polycarbonate properties:
