plasticizer plastics

shared by Becky Kriger on 08 Dec 08 - Cached
  • A plasticiser is a substance which when added to a material, usually a plastic, makes it flexible, resilient and easier to handle.
  • Today, modern plasticisers are manmade organic chemicals; the majority of which are esters, such as adipates and phthalates.
  • Importantly, they are not just additives (like pigments or fillers). They are major components that determine the physical properties of polymer products.

  • They are colourless, odourless liquids produced by a simple chemical reaction, whereby molecules of water are eliminated from commercially produced petrochemical products.
  • The most commonly used plasticisers are phthalates.
  • Predominantly, phthalates are used in the plastics industry to soften the popular plastic PVC. This is used to make a diverse range of cost effective products with various levels of technical performance suited to a wide range of applications. Many of these PVC products we use everyday but tend to take for granted. They include everything from lifesaving medical devices such as medical tubing and blood bags, to footwear, electrical cables; packaging, stationery, and toys.

Plastics recycle

shared by Becky Kriger on 08 Dec 08 - Cached
  • The easiest and most common plastics to recycle are made of polyethylene terephthalate (PETE) and are assigned the number 1. Examples include soda and water bottles, medicine containers, and many other common consumer product containers. Once it has been processed by a recycling facility, PETE can become fiberfill for winter coats, sleeping bags and life jackets. It can also be used to make bean bags, rope, car bumpers, tennis ball felt, combs, cassette tapes, sails for boats, furniture and, of course, other plastic bottles.
  • Number 2 is reserved for high-density polyethylene plastics. These include heavier containers that hold laundry detergents and bleaches as well as milk, shampoo and motor oil. Plastic labeled with the number 2 is often recycled into toys, piping, plastic lumber and rope.
  • Polyvinyl chloride, commonly used in plastic pipes, shower curtains, medical tubing, vinyl dashboards, and even some baby bottle nipples, gets number 3. Like numbers 4 (wrapping films, grocery and sandwich bags, and other containers made of low-density polyethylene) and 5 (polypropylene containers used in Tupperware, among other products), few municipal recycling centers will accept it due to its very low rate of recyclability.

  • Number 6 goes on polystyrene (Styrofoam) items such as coffee cups, disposable cutlery, meat trays, packing “peanuts” and insulation. It is widely accepted because it can be reprocessed into many items, including cassette tapes and rigid foam insulation.
  • Usually imprinted with a number 7 or nothing at all, these plastics are the most difficult to recycle and, as such, are seldom collected or recycled.
