Synthetic polymers: A variety of synthetic polymers as plastic (polythene), synthetic fibres (nylon 6,6) and synthetic rubbers (Buna - S) are examples of manmade polymers extensively used in daily life as well as in industry. INDUSTRIAL POLYMER SDN BHD (IP) was established during 2009 in Singapore. They are chemically inert, thermally stable and bad conductors of electricity. Most often derived from natural gas or from low-molecular-weight constituents of petroleum, they include ethylene, propylene, and butene (butylene). In the article industrial polymers, chemistry of, polymers are categorized according to whether they are formed through chain-growth or step-growth reactions. Polymer dispersions (latex, plastisols) can exhibit both shear thinning (pseudolplasticity) and shear thickening (dilatancy). Examples of condensation polymers include synthetic polymers like polyester, nylon etc. They are a main constituent of our food (starch, protein, etc. The word POLYMER comes from the Greek words poly means many and mer means parts . As a result, LDPE is only partly crystalline, yielding a material of high flexibility. Let us study in brief about few of the synthetic polymers used in everyday life-Nylon-Nylon belongs to the synthetic polymers family and is also known as polyamides. An increased amount of char reduces the amount of combustible gases reaching the flame. Example: during a registration year you start introducing 8 polymers that meet our PLC criteria and 4 that meet our low concern biological polymers criteria. Additives determine the composition of the polymer. Polymers exist as amorphous and crystalline solids. Cable Moulding. Six (6) industrial polymers were analyzed by GPC. For example, hexane can be cracked to form butane and ethene: hexane → butane + ethene. Composite materials have great physical, thermal, chemical properties. Some examples of new materials are special blends of existing polymers, polymer composites with fiber reinforcement, and liquid crystalline polymers. The results are summarized in Table 1-Table 6. A flame retardant blocks the release of gaseous fuel and result in charring which act as a thermal barrier. With the technological advancements that have been made in the last 20 to 40 years, there is little that cannot be attained by Industrial Polymers LLC. INTRODUCTION Polymers are very large molecules made when hundreds of monomers join together to form long chains . Its principal uses are in packaging film, trash and grocery bags, agricultural mulch, wire and cable insulation, squeeze bottles, toys, and housewares. – Polymers: Examples 2. Composite materials which consist of organic polymer matrix are reinforced with either glass or natural fibres.

Product examples: Coatings: waterproofing, abrasion resistance, corrosion control Encapsulates: electrical potting or cable application requiring waterproofing. Olefins are hydrocarbons (compounds containing hydrogen [H] and carbon [C]) whose molecules contain a pair of carbon atoms linked together by a double bond. As a result, the first industrial PE—actually an irregularly branched LDPE—was not produced until 1939 by Imperial Chemical Industries (ICI). LLDPE, for example, was introduced by the Phillips Petroleum Company in 1968. Major industrial polymers - Major industrial polymers - Fluorinated polymers: PTFE was discovered serendipitously in 1938 by a DuPont chemist, Roy Plunkett, who found that a tank of gaseous tetrafluoroethylene (CF2=CF2) had polymerized to a white powder. In most situations it can be assumed that flow is laminar. As the repeating unit of a polymeric molecule, their chemical structure can be represented as: The composition and structure of R determines which of the huge array of possible properties will be demonstrated by the polymer. I need to find 2 example of industrial (everyday) polymers. After the end of this registration year you will need to submit a single post-introduction declaration that tells us that you introduced 12 individual polymers.
