Plastic - Wikipedia Generic term used in the case of polymeric material that may contain other substances to improve performance or reduce costs. Note 1: The use of this term instead of polymer is a source of confusion and thus is not recommended. Note 2: This term is used in polymer engineering for materials often compounded that can be processed by flow. plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded
Corrugated plastic - Wikipedia Corrugated plastic or corriboard - also known under the tradenames of Polyflute, Coroplast, FlutePlast, IntePro, Proplex, Correx, Twinplast, Corriflute or Corflute - refers to a wide range of extruded twinwall plastic-sheet products produced from high-impact polypropylene resin with a similar make-up to corrugated fiberboard. It is a light-weight tough material which can easily be cut with a utility knife. Manufacturers typically offer a wide variety of colors and thicknesses (quite commonly 3,
Plastics in the construction industry - Wikipedia plastic is the generic name for a family of synthetic materials derived from petrochemicals. It is often product of two or more components. There are many families of plastics and polymers being used in construction industry. Examples of plastics used in building are: Acrylic · Composites · Expanded Polystyrene · Polycarbonate · Polyethylene · Polypropylene · Polyvinyl Chloride. in building materials. Some of these properties are:
Plastic joining - Wikipedia plastic joining is the method of joining semi-finished products of plastic materials together or to other materials as a fabrication process or damage repart. Joining methods can be classified into three categories: Mechanical fastening,; Adhesive bonding,; Welding. Contents.

History. Ralph Wiley accidentally discovered polyvinylidene chloride in 1933. He, then, was a college student who worked part-time at Dow Chemical lab as a dishwasher. While cleaning
Plastic pollution - Wikipedia plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans. plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size. The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans. However, it is slow to degrade. plastic pollution can unfavourably affect lands, waterways and oceans.
Plastic optical fiber - Wikipedia plastic optical fiber (POF) (or Polymer optical fibre) is an optical fiber that is made out of polymer. Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber. Its chief advantage over the glass product, other aspect being equal, is its robustness under bending and stretching. Optical fiber used in telecommunications is governed by European Standards EN 60793-2-40-2011.
Disadvantages of Plastic - Negative Effects of Plastic Even though plastic products have undeniable positive effect on our lives and industry, it still has several disadvantages. Those disadvantages can range from lack of durability in certain uses, chemical risks, and environmental harm to potential choking hazards.
Microcellular plastic - Wikipedia Due to the non-hazardous nature of this foam-generating process, these plastics are able to be recycled and put back into the production cycle, reducing their carbon footprint as well as reducing the cost of raw materials. With the porous nature of this material, the overall density is much lower than that of any solid plastic, considerably dropping the weight per unit volume of the part. This also entails less consumption of raw plastic with the
Plastic welding - Wikipedia plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling. Numerous welding methods have been developed for the joining of semi-finished plastic materials. Based on the mechanism of heat
Plastic wrap - Wikipedia plastic wrap, cling film (British), shrink wrap, Saran wrap, cling wrap, food wrap, or pliofilm is a thin plastic film typically used for sealing food items in containers to keep them fresh over a longer period of time. plastic wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container without adhesive. Common plastic wrap is roughly 0.5 Thousandth of an inch (12.5 μm) thick. The trend has been to produce
Plastic roads - Wikipedia plastic roads are roads made either entirely of plastic or of composites of plastic with other materials. plastic roads are different from standard roads in the respect that standard roads are made from asphalt concrete, which consists of mineral aggregates and asphalt. Currently, there are no records of regular roads made purely of plastic. plastic composite roads, however, have existed and demonstrate characteristics superior to regular asphalt concrete roads; specifically, they show
Microbead - Wikipedia Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension. They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene. They are used in exfoliating personal care products, toothpastes and in biomedical and health-science research. Microbeads can cause plastic particle water pollution and pose an environmental hazard for aquatic animals in freshwater and ocean
Biodegradable plastic - Wikipedia There are allegations that biodegradable plastic bags may release metals, and may require a great deal of time to degrade in certain circumstances and that OBD (oxo-biodegradable) plastics may produce tiny fragments of plastic that do not continue to degrade at any appreciable rate regardless of the environment. The response of the Oxo-biodegradable plastics Association (biodeg.org) is that OBD plastics do not contain metals.
