What Is HDPE Plastic?

HDPE Plastic

Plastic products have become widely popular nowadays. We use it in almost every area of our lives now. There are various types of plastics these days ranging from polypropylene to polyester. However, HDPE plastic is known to be one of the most versatile plastics. It has a lot of uses and is also extensively recycled.

Meaning of HDPE Plastic

HDPE is the abbreviated form of High-Density Poly Ethylene. It is essentially a thermoplastic plastic which is derived from petroleum. As we have stated earlier, the versatility of the plastic helps it mark a significant presence in various areas.

From plastic bottles and milk jugs to cutting boards and piping, you will find HDPE everywhere. Furthermore, it is renowned for the exceptional tensile strength it has plus its huge strength-to-density ratio. It also possesses a high-impact resistance and melting point.

Benefits of HDPE Plastic

HDPE Plastic is greatly used in various fields. Moreover, it has such characteristics that it makes it easier to use it for various purposes. Some of the benefits of HDPE plastics are:

Mouldable and Melts Easily

A major benefit of plastics is that they are naturally flexible. And to top this, HDPE particularly outshines the other plastics in this area.

The high melting point of the plastic helps it remain rigid at quite higher temperatures. However, once the plastic reaching its melting point, we can easily mould it for various purposes.

For instance, we can make detergent bottles, milk jugs, food containers, plastic lumber and much more.

Durable

This plastic is highly durable. It can resist mould, mildew and even rotting. Therefore, it makes for a great piping material through which water can be delivered easily.

Moreover, the weather-resistant feature makes it easier for it to store food and beverage in it. In addition, this plastic can endure strong mineral acids and bases as well as the chemicals which naturally occur in soil.

Most importantly, we see that it is practically impermeable to common chemicals, water, acids, and other fluids.

Higher Tensile Strength

It has quite a high tensile strength and strong intermolecular forces. It is primarily so because of the high density of the HDPE which ranges from 0.93 to 0.97 g.

Moreover, the little branching of its linear structure gives it the tensile strength too. Therefore, we see how even a 60 gram HDPE container carries more than a gallon of liquid easily.

Easy Recycling

As we all know that plastic does not decompose easily. Thus, recycling is the only way out. Fortunately, this plastic gets recycled easily.

Similarly, it helps the non-biodegradable waste stay out of landfills. It also drops the levels of plastic pollution by a great percentage.

Most importantly, it is a very cost-effective and environmentally responsible material perfect for numerous uses.

Products of HDPE Plastic

HDPE is present in more areas than you think. It is so because it is an easier alternative to heavier materials.

Furthermore, it helps companies and individuals in following their ecological and reasonable manufacturing plus assignment objectives.

It offers you the perfect blend of strength, cost-efficiency, as well as environmental responsiveness. Other than coming in use in the food sector, you will also find it in the following places:

  • Wood-plastic composites
  • Plastic surgery (skeletal and facial reconstruction)
  • Snowboards
  • Shoe Lasts
  • 3-D printing filament
  • Beverage vessels
