engineering plastic - wikipedia

engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such as mechanical parts), rather than for bulk and high-volume ends (like containers and packaging). the term usually refers to thermoplastic materials rather than thermosetting ones.【Get Price】

bioplastic - wikipedia

bioplastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, or microbiota. bioplastic can be made from agricultural by-products and also from used plastic bottles and other containers using microorganisms. common plastics, such as fossil-fuel plastics (also called petrobased polymers), are derived from petroleum or natural gas. production of such plastics tends to require more fossil fuels and to produce more greenhouse gases than 【Get Price】

fibre-reinforced plastic - wikipedia

fibre-reinforced plastic (frp) is a composite material made of a polymer matrix reinforced with fibres. the fibres are usually glass (in fibreglass), carbon aramid, or basalt. rarely, other fibres such as paper, wood, or asbestos have been used. the polymer is usually an epoxy, vinylester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. frps are commonly used in the aerospace, automotive, marine, and 【Get Price】

high-performance plastics - wikipedia

crystalline polymers (especially those reinforced with fillers) can be used even above their glass transition temperature. this is because semi-crystalline polymers have additional to the glass temperature tg the crystallite melting point tm, which is mostly much higher located. for example possesses peek a tg of 143 °c but is anyway applicable up to 250 °c (continuous service temperature = 250 °c). another advantage of semi-crystalline polymers is their high resistance against 【Get Price】

plastic recycling - wikipedia

plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. since the vast majority of plastic is non-biodegradable, recycling is a part of global efforts to reduce plastic in the waste stream, especially the approximately eight million tonnes of waste plastic that enter the earth's ocean every year. this helps to reduce the high rates of plastic pollution. plastic recycling includes taking any type of plastic, sorting it into different 【Get Price】

plastic bag - wikipedia

a plastic bag, polybag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. it is a common form of packaging. most plastic bags are heat sealed together. some are bonded with adhesives or are stitched.【Get Price】

acrylonitrile butadiene styrene - wikipedia

abs is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. the proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. the result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). the nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making abs stronger than pure polystyrene. the styrene gives the plastic 【Get Price】

wood-plastic composite - wikipedia

wood-plastic composites (wpcs) are composite materials made of wood fiber/wood flour and thermoplastic(s) in addition to wood fiber and plastic, wpcs can also contain other ligno-cellulosic and/or inorganic filler materials. wpcs are a subset of a larger category of materials called natural fiber plastic composites (nfpcs), which may contain no cellulose-based fiber fillers such as pulp fibers, peanut hulls, bamboo, straw, 【Get Price】

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 【Get Price】

plastic - wikipedia

generic term used in the 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 【Get Price】

plastics extrusion - wikipedia

advantages[edit]. a great advantage of extrusion is that profiles such as pipes can be made to any length. if the material is sufficiently flexible, pipes can be made at long lengths even coiling on a reel. another advantage is the extrusion of pipes with integrated coupler including rubber seal.【Get Price】

plastics in the construction industry - wikipedia

advantages[edit]. plastics are strong yet lightweight, and so they are easy to transport & manoeuvre. they are durable, knock-and scratch resistant with excellent weatherability. they do not rot or corrode. plastics are easy to install; many have a snap-fit kind of jointing procedures. plastics offer limitless possibilities in design achieved by extrusion, bending, moulding etc. they can be given any range of colours by adding pigments. the plastics are low 【Get Price】

biodegradable plastic - wikipedia

under proper conditions, some biodegradable plastics can degrade to the point where microorganisms can completely metabolise them to carbon dioxide (and water). for example, starch-based bioplastics produced from sustainable farming methods could be almost carbon neutral. there are allegations that biodegradable plastic bags may release metals, and may require a great deal of time to degrade in certain circumstances 【Get Price】

plastic - simple english wikipedia, the free encyclopedia

a plastic is a material that can change its shape. many things are made of plastics, usually because making them the right shape is easy. there are many types of plastic. some can be shaped only when they are freshly made; then they become hard. others are thermoplastic and can be softened by heating them. most plastics are man-made; they do not occur in nature. the process of making plastics is usually quite complicated. most of the materials that are called plastic are 【Get Price】

plastic bottle - wikipedia

plastic bottles were first used commercially in 1947 but remained relatively expensive until the early 1960s when high-density polyethylene was introduced. they quickly became popular with both manufacturers and customers due to their lightweight nature and relatively low production and transportation costs compared with glass bottles. however, the biggest advantage plastic bottles have over glass is their superior resistance to breakage, in both production and transportation.【Get Price】
