2mm 4mm 6mm 8mm 10mm 12mm 14mm 16mm Cellular Multiwall Polycarbonate Hollow Sheet Weather-resistant Polycarbonate Hollow Sheet

Weather-resistant Polycarbonate Hollow Sheet is a specialized variant of polycarbonate (PC) hollow sheets, engineered with advanced technologies to withstand harsh environmental conditions while retaining the material’s inherent advantages of lightness, impact resistance, and thermal insulation. Unlike standard PC sheets, its design prioritizes long-term stability against UV radiation, extreme temperatures, humidity, and chemical exposure—making it a reliable choice for outdoor and semi-outdoor applications where weather durability is critical.

Core Weather-resistant Technologies

The exceptional weather resistance of this sheet stems from two key engineering features:

Co-extruded UV Protection Layer

A dedicated anti-ultraviolet (UV) coating is co-extruded on one or both surfaces of the sheet during production. This layer is typically made of high-performance UV absorbers (e.g., benzophenones, triazines) and stabilizers that block up to 99% of harmful UVA and UVB rays. Unlike post-applied coatings (which can peel off over time), the co-extruded layer fuses with the PC base material, ensuring permanent protection. It prevents photo-oxidation of the PC polymer—an issue that causes standard plastics to yellow, become brittle, or lose transparency after prolonged sun exposure.

Enhanced Polymer Formulation

The PC resin used in weather-resistant variants is modified with heat stabilizers, hydrolysis inhibitors, and anti-oxidants. These additives resist degradation from extreme temperatures (ranging from -40℃ to 120℃) and high humidity:

Heat stabilizers prevent softening or warping in intense sunlight or hot climates.

Hydrolysis inhibitors block moisture absorption, which can otherwise break down PC molecular bonds and cause delamination of the hollow structure.

Key Weather-resistant Performance Traits

1,UV Resistance & Longevity

Accelerated aging tests (e.g., QUV testing, simulating 10 years of outdoor exposure) confirm that weather-resistant PC hollow sheets retain over 80% of their original light transmittance and mechanical strength. In real-world use, they typically maintain performance for 15–20 years—far longer than standard PC sheets (5–8 years) or acrylic sheets (3–5 years) in outdoor settings.

2,Temperature Extremes Tolerance

The sheet remains dimensionally stable across extreme temperature fluctuations. For example:

In cold regions, it resists embrittlement and cracking under freezing conditions (down to -40℃), making it suitable for greenhouse roofing in high-latitude areas.

In hot, arid climates, it does not soften or deform even when surface temperatures reach 60℃ (due to solar radiation), ensuring structural integrity for canopies or skylights.

3,Moisture & Chemical Resistance

The hydrolysis-resistant formulation and sealed hollow structure prevent water ingress and mold growth. Additionally, the sheet resists corrosion from common environmental chemicals, such as:

Acidic rain (pH 4.0–5.5)

Urban air pollutants (e.g., sulfur dioxide, nitrogen oxides)

Agricultural chemicals (e.g., fertilizers, pesticides) used in greenhouse applications.

4,Wind & Hail Impact Resistance

Combined with PC’s inherent high impact strength (250x that of glass), the weather-resistant variant’s rigid hollow structure withstands strong winds (up to 120 km/h) and hailstones (diameter up to 25 mm) without cracking. This makes it ideal for coastal areas prone to storms or regions with frequent hailstorms.

FAQ

1.Whats the quality assurance you provided and how do you control quality ?
1)Established a procedure to check products at all stages of the manufacturing process;Besides, we also developed a procedure which identifies the inspection and test status of all items at all stages of the manufacturing process.

2)100% inspection in assembly lines.

2.How many different kinds of PC sheet you can product?
There are the following products: Glittering Polycarbonate Sheet,Multi-wall Structure Polycarbonate Sheet,Greenhouse Polycarbonate Sheet, General Polycarbonate Solid Sheet,Advertising Polycarbonate Sheet, Polycarbonate Embossed Sheet, Polycarbonate Frosted Sheet, Soundproof Polycarbonate Sheet, Greenhouse Polycarbonate Sheet etc.
3.We are in very high temperature country, twin wall polypropylene sheet can support?
A: Yes, Polycarbonate sheet Temperature Resistance can be:40 ~+120 degree centigrade

4.Do you take special orders ?
Yes , We accept customized products.
5. How to identify the UV side of the sheet?
A: The UV side is the side protected with the printed masking film. To avoid installing the sheet at the wrong side which will void the warranty, please ensure only to remove the masking film after the sheet has been installed.

6. How do I know that a twin wall polypropylene sheet has UV layer?
A: You can’t see the UV layer with the naked eyes. A laboratory test is required to prove this. Some international labs have this facility. Usually UV side layer will more thicker than the down side.

Polycarbonate hollow sheet is made of polycarbonate (referred to as PC) material at high temperature. It has excellent properties such as heat preservation, flame retardant, UV protection, wind and rain resistance, light weight, sturdy and durable, and good aging resistance. The PC hollow sheet produced by our company is a high-quality sheet with a 10-year warranty. It is mainly used for the construction of large-scale projects such as canopy, carport, small flower house construction, highway noise barrier, and greenhouse .Our company's products can provide a variety of sheet colors, such as transparent, milky white, grass green, lake blue, mountain blue, brown, dark brown, etc., as well as custom-made sheet size and thickness customization.
