Polycarbonate

Polycarbonate Sheet – Virtually Unbreakable Plastic for Demanding Applications

Polycarbonate is one of the toughest transparent plastics available, offering impact resistance up to 250 times greater than standard glass. At Associated Plastics Tasmania, we supply and fabricate polycarbonate sheet in solid and multiwall configurations for applications where strength, safety, and durability are paramount.

From machine guards and safety shields to roofing panels and greenhouse glazing, polycarbonate delivers exceptional performance in the most demanding environments across Tasmania and Australia.

What Is Polycarbonate?

Polycarbonate is an engineering-grade thermoplastic known for its extraordinary impact resistance, optical clarity, and wide operating temperature range. It maintains its structural integrity from -40°C to over 120°C, making it suitable for virtually any Australian climate condition.

Available in two primary forms – solid sheet and multiwall (twinwall/triplewall) – polycarbonate can be tailored to suit applications ranging from crystal-clear machine guards to thermally insulating roofing panels.

Properties and Benefits

Exceptional Impact Resistance

Polycarbonate is virtually unbreakable under normal conditions. With impact resistance 250 times greater than glass and 30 times greater than acrylic, it is the go-to material for safety-critical applications including machine guards, security glazing, and protective barriers.

Optical Clarity

Solid polycarbonate transmits up to 88% of visible light, providing excellent clarity for applications where both visibility and strength are required. While slightly less clear than acrylic, the difference is negligible for most practical applications.

UV Protection

Quality polycarbonate sheet features a co-extruded UV-protective layer on one or both sides, blocking harmful ultraviolet radiation while maintaining light transmission. This UV layer protects both the sheet itself and the contents beneath it.

Wide Temperature Range

Operating effectively from -40°C to over 120°C, polycarbonate maintains its impact resistance and structural properties across extreme temperature variations. This makes it ideal for outdoor applications throughout Tasmania, from freezing highland winters to hot summer days.

Lightweight

Polycarbonate is approximately half the weight of glass, reducing handling requirements, structural loading, and installation costs – particularly important for overhead glazing and large panel applications.

Fire Resistance

Polycarbonate is self-extinguishing and achieves good fire ratings, making it suitable for applications where fire performance is a consideration. It does not produce toxic gases when exposed to flame.

Types of Polycarbonate

Solid Polycarbonate Sheet

Clear, flat polycarbonate sheet available in thicknesses from 1mm to 15mm and beyond. Used for machine guards, security glazing, safety barriers, windscreens, and any application requiring maximum impact resistance with optical clarity.

Multiwall Polycarbonate (Twinwall/Triplewall)

Structured polycarbonate panels with internal channels that provide excellent thermal insulation and light diffusion while maintaining lightweight strength. Available in thicknesses from 4mm to 25mm, multiwall polycarbonate is the preferred choice for roofing, greenhouse panels, and architectural cladding.

Polycarbonate vs Acrylic – Which Should You Choose?

Both materials are popular plastic glazing options, but they serve different purposes:

• Choose polycarbonate when impact resistance is critical – machine guards, safety barriers, security glazing, high-traffic areas, areas prone to vandalism
• Choose acrylic when optical clarity and scratch resistance are priorities – display cases, signage, aquariums, decorative panels
• Temperature – polycarbonate handles higher temperatures and wider temperature swings
• Fabrication – acrylic produces cleaner laser-cut edges; polycarbonate is better suited to CNC routing and mechanical fastening

Common Applications

Machine Guards and Safety Shields

Polycarbonate is the industry standard for machine guarding. Its virtually unbreakable nature protects operators while allowing full visibility of machinery operation. We custom-cut and fabricate machine guards to suit any equipment configuration.

Security Glazing

Banks, government buildings, retail premises, and high-security environments use polycarbonate glazing for its resistance to forced entry. It can withstand repeated heavy impacts without breaking through.

Roofing and Skylights

Multiwall polycarbonate panels are widely used for pergola roofing, carport covers, verandah enclosures, and skylights throughout Tasmania. They provide natural light while offering UV protection, thermal insulation, and hail resistance superior to glass or fibreglass alternatives.

Greenhouse and Agricultural

Multiwall polycarbonate is the premier greenhouse glazing material, offering excellent light diffusion, thermal insulation, and the strength to withstand Tasmania’s sometimes harsh weather conditions. It outperforms glass in thermal performance and safety.

Noise Barriers

Solid polycarbonate sheet is used for noise barriers and acoustic screens in commercial, industrial, and roadside applications where both sound reduction and visibility are required.

Protective Barriers and Screens

From sports venues to industrial environments, polycarbonate barriers provide impact-resistant protection. Our custom fabrication service produces barriers and screens to any size and specification.

Frequently Asked Questions

Can polycarbonate be used for roofing in Tasmania?

Absolutely. Multiwall polycarbonate is one of the most popular roofing materials in Tasmania for pergolas, carports, and verandahs. It provides excellent UV protection, thermal insulation, and easily handles Tasmanian weather conditions including hail, wind, and snow loads.

Does polycarbonate yellow over time?

Quality polycarbonate with UV-protective coating will resist yellowing for 10+ years under normal conditions. The co-extruded UV layer is critical – always ensure your polycarbonate is UV-protected for outdoor applications.

Is polycarbonate suitable for food contact?

Yes, certain grades of polycarbonate are approved for food contact applications. Contact our team to discuss food-grade polycarbonate options for your project.

Can you cut polycarbonate to custom sizes?

Yes. Our CNC cutting equipment handles both solid and multiwall polycarbonate with precision. Provide your dimensions and we will cut to exact specifications with clean, professional edges.
