Plastics are comprised of a long chain of polymers, where polymers are composed of smaller, uniform molecules. What Are Polymers? Polymers are lengthy chain compounds composed of monomers. Plastic is a specific type of polymer.
UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and reduces the molecular weight, causing deterioration of mechanical properties and leading to useless materials, after an unpredictable time. ©2002 John Wiley & Sons, Inc. M P Groover, “Fundamentals of Modern Manufacturing 2/e” More Plastic Products •In addition, plastics are often the principal ingredient in other materials, such as Paints and varnishes Adhesives Various polymer matrix composites •Many plastic shaping processes can be adapted to Plastic barrels have become a hot item in recent years for catching rainwater that can be reused and re-purposed for all kinds of things.

Thus, even when plastics have a resin code, or are collected for recycling, only a small portion of that material is actually recycled. For example, as of 2017, only 8% of US plastic was recycled. Plastics #1 and #2 are the most common types of plastic containers and the most easily recyclable. They are also the most likely to have a California Redemption Value ( CRV) associated with them.

16, 2018 Posted May. Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together. Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times.

Making a plastic mold can be done in a few steps if you want to make copies of an existing object, according to Bright Hub Engineering. The mold is created from a two-ingredient liquid compound that sets up overnight before you cast the pla
In the 1950s, most people considered plastic a miracle material. But, nowadays, there's far more awareness about the toxic nature of plastic manufacturing, recycling and use. Namely, plastic doesn’t degrade readily, which means a single pla
A polymer is a type of chemical compound whose molecules are bonded together in long repeating chains.
