Exposure to the sun can cause staining, damages, and fading of any outdoor furniture made from wood, metal, or other materials. It is a process known as weathering.
Weathering is simply the way outdoor objects break down from exposure to time, moisture, and sunlight. Any natural material that gets too much exposure will fade or rot away due to the chemical changes brought upon by oxygen actively working with the material’s surface. Choose polyethylene plastic for outdoor furniture, be it plastic porch swings or any other kind of outdoor furniture. Wondering why? Here are the reasons.
Types of Polyethylene:
It’s good to know the types of polyethylene before moving ahead. So here are some of the most common types of Polyethylene plastics:
- Low-density Polyethylene (LDPE)
Low-density polyethylene (LDPE) is a plastic polymer used to produce films, packaging, cling wrap, and other thin sheeting.
- The Linear Low-Density Polyethylene
The linear low-density polyethylene, or LLDPE, is the most common type of polyethylene. This polymer has a very low density and high tensile strength. LLDPE is also known for its wide range of physical properties, from stiffness to toughness.
- High-density Polyethylene
HDPE is a specially designed type of plastic that is more durable, stronger, and more transparent than any other type of plastic. HDPE can make packaging materials resistant to heat, cold, and humidity in terms of the industry.
- Ultra High Molecular Weight Polyethylene
Molecular Weight Extremely High Polyethylene (UHMW) is a thick kind of polyethylene that can be turned into elastic threads with tensile strengths significantly higher than steel; it’s often used in high-performance gear like body armor.
Benefits of Polyethylene plastics:
There are several benefits for businesses that use this kind of plastic, and these benefits often outweigh any potential drawbacks. Below are some advantages that attract companies to this type of material:
Polyethylene Plastic Is Flexible:
Polyethylene plastic is flexible— therefore, it can be bent, stretched, and molded to form many different shapes. It makes it perfect for projectors, outdoor plastic porch swings, and other outdoor furniture pieces that will often need to be moved around.
Polyethylene Plastic is Weatherproof:
It can withstand harsh weather conditions, including strong winds, rain, extreme heat, and cold, and it doesn’t seem to warp or degrade over time like some other outdoor surfaces. Polyethylene can be easily cleaned and will not rot, chip, crack or peel when exposed to sunlight.
Polyethylene Plastic Is Durable:
Many people who purchase outdoor equipment know that polyethylene plastic is best because it is reusable and durable. Most don’t realize that polyethylene has qualities that make it even better than polypropylene when it comes to durability. That means you can use it for more than just plastic porch swing sets.
Polyethylene Plastic Needs Low Maintenance:
Polyethylene plastic needs low maintenance because it is easy to clean and resistant to the effects of sunlight. All you need is a wet cloth for dusting down and a hosepipe to wash off any fallen leaves on the chairs’ or tabletops.
Eco-Friendly:
The environmental factors that cause polyethylene plastic to be so appealing are its low molecular weight and high oxygen permeability. It makes it easy for polyethylene to diffuse into the atmosphere and be eaten up by the surrounding organisms. It also makes it possible for the polymer film to become hard or brittle under certain conditions like high temperature or humidity levels.
Summing Up:
Due to its benefits, polyethylene is excellent for producing outdoor furniture such as patio sets, chairs, plastic porch swings, and much more. In addition, polyethylene chairs have an advantage over other types because they can resist water, dust, dirt, and even UV rays, making them more durable than any other type of material used in outdoor furniture.
Polyethylene vs Other Outdoor Furniture Materials
| Material | Good points | Weak points |
|---|---|---|
| Polyethylene (HDPE) | Weatherproof, low maintenance, does not rot or rust | Can fade in strong sun over many years |
| Wood | Natural look, strong | Needs sealing; can rot, crack, and fade |
| Metal | Strong, modern look | Can rust; gets hot in the sun |
| Wicker | Light, classic look | Can break and is hard to clean |
| Aluminium | Light, does not rust | Can dent; may feel cold |
Outdoor furniture must survive sun, rain, and wind. Wood looks natural and strong. But wood needs sealing. It can rot, crack, and fade. It needs care each year. Metal looks modern and strong. But it can rust. It gets hot in the sun. Wicker is light and classic. But it can break. It is hard to clean. Aluminium is light and does not rust. But it can dent. It may feel cold to sit on. Polyethylene plastic is different. It is weatherproof. It can withstand harsh weather conditions, including strong winds, rain, extreme heat, and cold. It does not rot. It does not rust. It does not need painting or sealing. It is easy to clean. A wipe with soap and water is enough. It is also light. You can move it easily. It is made in many colours. It does not need cushions to be comfortable, though cushions help. High-density polyethylene, or HDPE, is the best type for outdoor furniture. It is more durable, stronger, and more resistant to heat, cold, and humidity than other types. Many outdoor furniture makers use recycled HDPE. Recycled HDPE is made from old plastic bottles and containers. It is strong and safe. It keeps plastic out of landfill. This makes it a good choice for the environment. When you buy, check the label. Look for HDPE. Ask if the plastic is recycled. Ask about the warranty. A good maker offers a warranty of several years.
How to Clean and Care for Polyethylene Outdoor Furniture
Polyethylene furniture needs little care. But some care keeps it looking good. Clean it once a month. Use warm water and mild soap. Scrub with a soft brush. Rinse with clean water. Let it dry in the air. Do not use bleach. Bleach can fade the colour. Do not use a hard wire brush. It can scratch the surface. For tough stains, use a paste of baking soda and water. Rub it gently. Rinse it off. For mould, use a mix of water and white vinegar. Spray it on. Leave it for 10 minutes. Scrub and rinse. Keep the furniture out of strong sun when you do not use it. A cover helps. A cover stops dust and bird droppings. It also slows fading. In winter, store the furniture in a shed or garage if you can. If you cannot, cover it. Check the furniture each spring. Look for cracks. Look for loose screws. Tighten screws. Replace broken parts. A small fix now stops a bigger problem later. If the colour fades, you can use a plastic restorer. It is a liquid that brings back the colour. Test it on a small hidden area first. Polyethylene furniture can last 10 to 20 years with basic care. That is longer than most wood furniture. It is also cheaper to keep. You do not need to buy paint, oil, or sealant each year. This saves money over time.
