Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Plexiglas, Acrylite, Lucite, and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass.
Plastics can be made in a variety of ways from a variety of materials; shale gas, oil, plants even chicken feathers can all be used to make plastic. However oil derived plastics are the most common. Plastics are created from single units combined in a variety of ways.
PC is commonly used for plastic lenses in eyewear, in medical devices, automotive components, protective gear, greenhouses, Digital Disks (CDs, DVDs, and Blu-ray), and exterior lighting fixtures. Polycarbonate also has very good heat resistance and can be combined with flame retardant materials without significant material degradation.
Polyethylene has more demand however than polypropylene. Polypropylene is used extensively in the automotive industry as well as the packaging industry. 70% of the polypropylene uses is for packaging needs for the food industry. It can be made into bottles, food containers, food crates and pallets.
Plastics like PET most likely touch your everyday life. Polyethylene Terephthalate, known commonly as PET or PETE is best known as the clear plastic used for water and soda bottle containers. As a raw material, PET is globally recognized as a safe, non-toxic, strong, lightweight, flexible material that is 100% recyclable.
Polylactic Acid (PLA) is different than mo st thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane. Most plastics, by contrast, are derived from the distillation and polymerization of nonrenewable petroleum reserves.
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.
Examples of thermosetting plastics include phenolic resins, amino resins, polyester resins, silicon resins, epoxy resins, and polyurethanes. Thermosetting plastic recycling Although thermosetting plastics cannot be melted into new products, they can still be reused for other applications. An excellent example is polyurethane foam. Flexible polyurethane foams are commonly shredded into small flakes and re-manufactured into carpet underpayment.
