High Density Polyethylene

HDPE or high-density polyethylene is a colourless and odourless polyethylene thermoplastic. Known for its high strength-to-density ratio, HDPE is used as a major raw material in the manufacturing and processing industry. From safe food storage containers to high quality fuel tankers, there is a huge demand for HDPE in a wide range of applications.

HDPE is made from petroleum or semi-crystalline polyethylene products using a high intense process known as cracking. It involves production of ethylene gas which under controlled conditions are converted into a strong, highly resistant polymer. The resulting polymer is then processed through minute holes and gradually cut down to form what is called HDPE granules. There are various grades of HDPE available in the market and these are categorised based on their properties and industry specific requirements. Some of the commonly used HDPE grades include Polystone P5300, B5500, E5201, and F5400.

High-density polyethylene enjoys a position above conventional raw materials like steel, glass or even PVC tubes as it is considered to be safer and cost-efficient. Studies have shown that the recycling of an HDPE product involves less energy loss and cost than traditional methods of recycling practiced in the industry. Some of the key advantages of HDPE includes:

• Highly flexible and durable
• High strength-to-density ratio
• High temperature resistance
• Chemical and corrosion resistance
• No leak rate
• Recyclable and eco-friendly
