Clear plastics are everywhere in modern life, protecting storefronts, showcasing products, shielding machinery, and enhancing architectural designs. While acrylic, polycarbonate, PETG, and PVC may appear similar at first glance, each is engineered with distinct properties that make it better suited for specific applications.
From impact resistance and optical clarity to chemical durability and ease of fabrication, the material you choose directly influences the performance and longevity of your project. At Piedmont Plastics, we help customers select the right clear plastic and achieve reliable, lasting results. Read this guide to the best clear plastic options and how to choose the right one for your application.

Why Choosing The Right Clear Plastic Matters
Each type of clear plastic is designed with its own set of performance characteristics. Determining the best option for your project isn’t just about durability: it can also impact efficiency, appearance, and safety. By taking the time to understand these differences, you can:
Enhance Design Flexibility: Some plastics are easier to shape, cut, or thermoform, giving you more creative freedom in product design.
Achieve Better Visual Results: The right choice can maximize light transmission, reduce glare, or maintain color consistency for display and signage applications.
Support Regulatory Compliance: Certain clear plastics meet industry standards for food contact, medical use, or flame resistance, ensuring your project aligns with required guidelines.
Simplify Maintenance: Materials with higher scratch resistance, chemical tolerance, or weatherability make cleaning and upkeep easier over the long term.
With these benefits in mind, let’s examine the four primary types of clear plastic (acrylic, polycarbonate, PETG, and PVC) and see how their distinct properties add value across different applications.
Acrylic (PMMA)
Acrylic is a rigid, optically clear plastic often chosen as a lighter, shatter-resistant alternative to glass.
Key Benefits:
- Superb transparency and light transmission
- Half the weight of glass with superior shatter resistance
- Seventeen times stronger than glass and more cost-effective
- UV and moisture resistant, allowing it to resist yellowing outdoors
- More scratch resistant than polycarbonate
- More resistant to weather and impacts than glass
- Easy to shape, cut, drill, and fabricate
Considerations:
- More brittle than polycarbonate
- Can crack under high impact
- Less impact resistance in tough environments
Applications:
- Aquariums
- Advertising displays
- Teller window glazing
- Signage
- Display cases
- Windshields
- Safety partitions
Common Industries:
- Sign and graphics
- Security and safety
- Building and construction
- Transportation
Polycarbonate (PC)
Polycarbonate is an exceptionally tough, lightweight plastic known for its nearly unbreakable strength.
Key Benefits:
- Up to 200 times stronger than glass and 30 times stronger than acrylic
- High impact resistance, making it suitable for demanding environments
- Withstands high service temperatures and tough weather conditions
- Doesn’t shatter like glass or crack like other plastics
- Easy to machine and thermoform
- Terrific for applications requiring both visibility and strength
- Can be treated with UV and flame-resistant coatings
Considerations:
- Prone to scratching without protective coating
- Higher cost compared to acrylic and PETG
- Requires UV stabilization for outdoor use
Applications:
- Skylights and windows
- Safety glazing
- Protective barriers
- Medical devices
- Riot shields
- Signs and displays
Common Industries:
- Security and safety
- Building and construction
- Performance glazing
PETG
PETG is a strong and versatile thermoplastic that offers a great balance of clarity and durability.
Key Benefits:
- Durable and FDA-approved
- Outstanding chemical resistance
- High impact resistance compared to acrylic
- Cost-effective alternative to polycarbonate
- Easy to fabricate and thermoform
- Can be cold bent without showing stress whitening
- Strong under pressure without cracking
Considerations:
- Softer surface, making it prone to scratching
- Can become tacky when cutting or machining
- Not as rigid as acrylic
Applications:
- Retail display cases
- Signage
- POP displays
- Safety shields
- Food storage bins
- Medical implants
- Packaging materials
- Machine guards
Common Industries:
- Food processing
- Medical
- Packaging
- Industrial
PVC (Polyvinyl Chloride)
Clear PVC is valued for its strength, chemical resistance, and versatility, making it perfect for industrial applications.
Key Benefits:
- Durable, lightweight, and cost-effective
- Resistant to many harsh chemicals
- Fire and mold-resistant
- Easy to thermoform and shape
- Available in rigid and flexible grades
- Terrific mechanical strength
- Can be machined to tight tolerances
Considerations:
- Low heat resistance
- Low maximum service temperature
- Can yellow over time with UV exposure
Applications:
- Aquariums and hydroponics
- Fluid transfer tubing and hoses
- Protective observation barriers
- Enclosures and curtains
- Signage and displays
- Packaging and covers
Common Industries:
- Industrial
- Building and construction
- Chemical manufacturing
- Medical
