Polyethylene packaging protects the products and extends its shelf life, with the possibility of diverse shapes and prints, together with the lower costs of transport and storage. Low density polyethylene LDPE is mostly used for production of shopping and bags, milk and water packaging foils, industrial bags, shrink and agricultural foils, insulation of electric conductors and cardboard lining.
Polyvinyl chloride, the main ingredient of PVC pipe, is classified as a known human carcinogen. Stabilizers and plasticizers used in PVC production may contain lead or other heavy metals, and during incineration—a common form of disposal—hydrochloric acid is released.
Variations in PE pipe density 0.9371– 0.9547 g / cm 3 , crystallinity 69–72%, crosslinking 60 and 76%, and oxidative induction time 33 to 295 min. were detected.
The Plastic Pipe and Fittings Association Polyethylene PE pipe was first commercially made in the 1940s, after World War II. Today, it is the second most widely used plastic pipe material, after polyvinyl chloride PVC. These two materials account for over 90

1/1/2017· Tel.: +91-1596-515205; fax: +91-1596-242183. E-mail address: ksspilani.bits-pilani.ac Abstract The growth in thermoplastic market is increasing rapidly as a replacement of cement, wooden, and metal products. The growth in plastic production has been around 9% since 1950s. 80% of the consumed plastic is thermoplastic.
The study used life cycle assessment methodology to evaluate the cradle-to-grave sustainability of commonly used drinking water and sewer pipe materials, including polyvinylchloride PVC, concrete, ductile iron, and high density polyethylene pipes over a 100
Plastic #2: High Density Polyethylene HDPE Advertisement This plastic is used to bottle milk, water, juice, cosmetics, shampoo, dish and laundry detergents and, cleaners.
Class of polyethylenes. HDPE has SPI resin ID code 2. High-density polyethylene HDPE or polyethylene high-density PEHD is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes.

20/11/· In supporting documentation, the PVC Pipe Association hypothesizes that certain high-density polyethylene HDPE pipe grade compounds can be susceptible to microscopic crack propagation in high-pressure water service, though it acknowledged that newer
Health Concerns According to the Foundation for Achievements in Science and Eduion fact sheet, long term exposure to small quantities of styrene can cause neurotoxic fatigue, nervousness, difficulty sleeping, hematological low platelet and haemoglobin values, cytogenetic chromosomal and lymphatic abnormalities, and carcinogenic effects.
Polybutylene PB Pipe is a form of plastic polymer that was used in the manufacture of potable water piping from late 70''s until 1995. However, it was discovered that the polyoxymethylene POM or Acetal connectors originally utilized to connect the polybutylene tubes were susceptible to stress enhanced chemical attack by hypochlorite additions a common chemical used to sanitize water.
