Does polycarbonate block UV radiation? Polycarbonate as a material blocks almost the entire relevant UV spectrum, meaning both UVA and UVB. The material absorbs UV radiation and does not allow it to be transmitted through.
Can you get sunburned through polycarbonate?
The good news is that polycarbonate is able to block both Ultraviolet A and Ultraviolet B by absorbing the radiation and preventing it from being transmitted. Polycarbonate UV resistance can actually protect the skin better than sun block creams; even a very thin polycarbonate sheet absorbs the UV rays.
What are the disadvantages of polycarbonate?
The biggest disadvantage is their high price - certainly higher than plastic or glass and as a result, customers opt for Acrylonitrile Butadiene Styrene (ABS) which is tougher, but not impact and heat resistant.

Some studies have found that BPA can leak trace amounts from polycarbonate containers and resin linings into foods and drinks. In tests on lab animals, BPA appears to copy or disturb the hormone estrogen and affect the reproductive system. This could possibly raise the risk for cancer.
What is the life expectancy of polycarbonate?
With an average lifespan of 10 to 20 years (and potentially even longer with proper care), they offer excellent value for money. Whether you're building a new home, renovating an old one, or just looking to replace your current roof, polycarbonate panels are certainly worth considering.
How do you reduce heat under polycarbonate sheets?
Polycarbonate maintains its properties over a wide range of temperatures, from -20 to 140°C. Its glass transition temperature is around 147°C, and it softens gradually above this point and flows above about 155°C. Standard polycarbonate resins are not suitable for long term exposure to UV radiation and may embrittle.
How does polycarbonate react to heat?
The first problem is UV stability. While UV stability of plastics has improved dramatically over the last few decades, polycarbonate does not have the UV stability of glass which seems to be all but impervious to the damaging effects of the sun.
Why is polycarbonate not used in windows?
If you're looking for a cheap and virtually shatterproof material for your greenhouse, polycarbonate is the way to go.
Is polycarbonate OK for a greenhouse?
Ideal temperatures for thermoforming polycarbonate are between about 300 and 500°F. Polycarbonate becomes more flexible the higher the temperature, but if you heat it long enough or exceed the limit of its operational temperature range (215°F – 450°F), it becomes difficult to use.
What is the temperature rating of polycarbonate?
Polycarbonate can handle temperatures up to 115 degrees Celsius, which is significantly higher than acrylic. The melting point of polycarbonate is around 300 degrees Celsius, much higher than acrylic. However, its density is comparable to acrylic and reaches around 1.2 g/cm3.
Does polycarbonate melt or burn?
Since glass absorbs all UVB radiation, exposure of the skin to sunlight that passes through glass, plexiglass, and plastic will not result in any production of vitamin D3 in the skin (Fig. 29).
Can you get vitamin D through polycarbonate?
The UV protection side is always under the branded film. When installing polycarbonate roofing, keep a minimum pitch of 5 degrees so that rainwater runs off towards the gutter preventing moisture collecting on your roof.
Which is the UV side of polycarbonate?
Unlike glass, polycarbonate can withstand extreme temperatures making it safer to use in building construction, and household items. Polycarbonate can be exposed to temperatures around 270 degrees for several hours or sudden bursts of heat up to 1166 degrees without distortion, breakage, or absorption of heat.
Is polycarbonate plastic heat resistant?
UV resistance on polycarbonate formulation can be added to the resin or developed as a coating. UV stabilizers are added to polycarbonate to help protect the material from the effects of exposure to the sun, and indoor lighting.
