High-density polyethylene, or HDPE, is perhaps the most versatile plastic for outdoor use. Many park benches, tables and chairs are now made using HDPE plastic, and playground equipment, in general, is made of HDPE thanks to its sturdiness.

Which plastic is best in the sun?
Polyetherimide. Polyetherimide (PEI) is a UV resistant plastic that is particularly useful in industrial, mechanical, and chemical applications. It is an exceptionally strong material that exhibits superior heat resistance, tensile strength, and chemical stability when exposed to acids.
What is the most UV resistant plastic?
Without further ado, here’s our list of the top five UV-resistant plastics:
- Acrylic.
- High Density Polyethylene (HDPE)
- Polycarbonate.
- Polyamide-Imide (PAI)
- Polyvinylidene Fluoride (PVDF)
- Improving UV resistance in plastics.
- Start making parts with UV-resistant plastics.
What kind of plastic is waterproof?
Whether you choose acrylic, polycarbonate, or HDPE, you will have the best building material to give you a strong and durable outdoor structure. These plastics have superior weatherability, UV resistance, and durability. Contact Proto Plastics to learn more about the available plastics for your next outdoor project.
Is HDPE good outdoors?
HDPE plastic can also withstand strong mineral acids. It doesn’t easily get damaged by common chemicals, water, cleaning fluids or detergents. It also has a large strength-to-density ratio and is impact-resistant, all of which makes HDPE plastic highly durable and a perfect material for any outdoor furniture.
Is acrylic or polycarbonate better for outdoor use?
Polycarbonate Plastic for Outdoor Use
It’s thirty times stronger than acrylic, but also notably more expensive than acrylic. Polycarbonate plastic is available in a wide range of thicknesses and strengths, lending it to a variety of different purposes.
Does polycarbonate degrade in sunlight?
However, bisphenol A polycarbonate is susceptible to photodegradation under ultraviolet (UV) radiation, which causes breakdown of the material, leading to yellowing, loss of toughness and embrittlement.
How long does polypropylene last in the sun?
6 days
Polypropylene is highly susceptible to degradation by UV radiation in its base form (i.e. no pigment or additives). The material becomes brittle after prolonged exposure. In fact, basic polypropylene can lose up to 70% of its mechanical strength after 6 days worth of exposure to high-intensity UV radiation.
What plastics block UV?
Good resistance to ultraviolet rays can be achieved from polymers extruded by Zeus such as PTFE, PVDF, FEP, and PEEKTM. The only plastics found with excellent resistance are the imides, Polyimide (PI) as used in the Hubble Space Telescope and Polyetherimide (PEI).
Does acrylic yellow in the sun?
Acrylic (Plexiglas®, Lucite®, and Acrylite®) comes from natural gas and is completely inert when in solid form. American-made acrylic does NOT yellow in the sunlight. Witness the protective canopies and bubbles in the World War II bombers- they are still clear after 50 years in the sun!
What is the most durable plastic?
High-density polyethylene (HDPE)
HDPE is a durable, versatile thermoplastic that offers fantastic impact resistance and tensile strength. Since its molecules are packed together so tightly, HDPE boasts incredible toughness and rigidity. HDPE is also resistant to chemicals, corrosion, absorption, and abrasion.
Is polypropylene plastic good for outdoors?
Are polypropylene sheets suitable for outdoor use? Yes! Polypropylene is a stable material under outdoor conditions.
What is the most durable plastic in the world?
Polycarbonate is one of the best impact resistant plastics available. This tough material is 250 times stronger than glass and 30 times stronger than acrylic.
Will HDPE warp in the sun?
All Answers (3) High-density polyethylene (HDPE) is recommended due to its high strength property as well as it can withstand continually 110 Celsius Degree. For usage in the direct sunlight, it is recommended to add UV stabilizer or add at least 2.5% carbon black.
How long does HDPE last outside?
Using a mean SSDR for HDPE in the marine environment, linear extrapolation leads to estimated half-lives ranging from 58 years (bottles) to 1200 years (pipes).
Does clear polycarbonate turn yellow?
Unlike acrylic though, the colour clarity of polycarbonate does diminish over time and will adopt a yellow hue with prolonged exposure to the UV rays.
Which is more expensive acrylic or polycarbonate?
Polycarbonate Plastic
One of the biggest differences between acrylic and polycarbonate is the cost. Polycarbonate sheets can cost on average about 35% more than acrylic.
Which is more scratch resistant acrylic or polycarbonate?
Polycarbonate offers much more resilience than acrylic, making it ideal for highly demanding applications like bullet-resistant windows. Acrylic has a high gloss finish and is more transparent, making it ideal for display cases. Acrylic is also easier to crack, while polycarbonate is easier to scratch.
How long does polycarbonate last in the sun?
Though polycarbonate is durable, it should be treated with UV protectant to prevent it from turning yellow or breaking down. With proper care, polycarbonate can last about 10 years, a fraction of how long glass lasts.
How long will polypropylene last?
Once in landfills, polypropylene slowly degrades and can take anywhere from 20-30 years to totally breakdown. This characteristic poses massive environmental concerns because the additives used in the manufacturing may include toxins like cadmium and lead.
Can you get sunburn through polycarbonate?
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.
