HDPE is the most popular and commonly used plastic in the world, accounting for nearly 20% of the plastic market, and is often used to make plastic bottles, chemical containers, piping systems, etc. HDPE is a commonly used plastic. In this article, we will discuss the advantages and disadvantages of HDPE.
Advantages of HDPE
1. Good ductility. HDPE has many useful properties that make it suitable for a variety of applications. Good ductility and good impact strength; it stretches rather than breaks. 2. Very low water absorption. HDPE is waterproof and durable, so it lasts longer when exposed to the elements compared to other polymers. 3. Antistatic. HDPE is a good electrical insulator that provides resistance to electrical tree effects, but can carry static electricity. Adding an antistatic agent can prevent this from happening. 4. Recyclable. HDPE can be recycled into other products, which is more cost-effective than making new products out of new plastic. 5. Chemical resistance. The chemical resistance of HDPE makes it ideal for laundry, shampoos, conditioners, household cleaning products, motor oils, antifreeze and recycling bins. When these bottles are tinted or tinted, their intensity increases. 6. Low temperature resistance. HDPE sheet has the ability to withstand -220 to 180 degrees Fahrenheit, which makes it useful in many industrial applications. For example: HDPE pipe system, the low temperature impact resistance of HDPE pipe is very good, the low temperature embrittlement temperature is extremely low, and it can be used safely in the temperature range of -60-60 °C. During construction in winter, because the material has good impact resistance, it will not occur. The tube is brittle.
HDPE, despite its popularity, has drawbacks that may prevent manufacturers and consumers from using it.
Disadvantages of HDPE include:
1. High thermal expansion. HDPE pipes can crack and be damaged when exposed to high temperatures. In some cases, pipes must be replaced. 2. Sensitive to stress cracking. HDPE cannot withstand stress and will crack under certain conditions. 3. Not suitable for high temperature. Like most plastics, HDPE pipe is not suitable for installation in high temperatures in direct sunlight or in any situation where continuous operation at extremely high temperatures is expected. 4. Combustible. HDPE is not fire-resistant. Once a fire occurs, it will burn. It can be extinguished by adding flame retardants. 5. Non-biodegradable. Like many other plastics, HDPE takes a long time to decompose, so it could end up in landfills for decades, and we're running out of space. 6. Limited access to raw materials. HDPE is mainly extracted from oil or natural gas, but the quantity is limited, if it needs a lot of energy to produce polyethylene, it will lead to a lot of carbon dioxide emissions, which will lead to global warming and climate change.
