(Low Density Polyethylene)
PE is made in 2 main types: HDPE and LDPE. It is a polyolefine. LDPE is usually a soft plastic type. It is tough, though not very strong and has a reasonable impact resistance. Making PE stronger with glass fibre is not usual practice. PE has excellent isolation properties, making it suitable for electrical isolation. Furthermore, PE is resistant against acids, bases, saltsolutions, water, alcohol and oils.
LDPE can be used up to 80-95 degrees celcius and becomes breakable at -50. About 75% of all PE is manufactured to LDPE, which is mainly used for sheets or film (bags, packing material etc.).
Waste LDPE requires special grinders to handle the thin films. The films can be either washed and repelletised, or used directly to make new products. The newly created LDPE pellets can be used alone, or mixed with virgin material for better properties of the end-product. Manufacturers use recovered LDPE to manufacture a variety of products including irrigation pipe, rubbish bags, black film and sheeting for the agricultural and building industries, and cable cover for the electrical industry.
Recently, new techniques have come available to be able to sort LDPE film better, and to be able to clean dirty films, such as agricultural LDPE film.
Heathland searches to recycle plastics, including LDPE, in ways that are best suitable for people and environment. Recycling happens in-house and at partner companies in Europe and/or Asia. Since the market for plastic recycling is very international, often it is difficult to keep track of how and where scrap plastics are recycled. Heathland works with partners who are qualified, have sufficient certification, and have set quality standards for the circumstances in which plastic materials are processed. This way, the company can keep as much control as possible on the circumstances in which it’s plastics are recycled. If you are interested in this way of recycling, whether your company is a collector, manufacturer, servicer or end-user, please contact us for possibilities.
