Discovering
\nthe Polymers<\/strong><\/h1>\n

The world of polymers is complex and fascinating.Educating is one of IPPR’s missions<\/strong>, which is why you will find below a detailed analysis of the complex world of polymers, in terms of materials, transformation processes and application sectors. Indeed, there is something for everyone.<\/p>\n

Plastic<\/strong>: families and materials<\/h2>\n

From a chemical viewpoint, plastics are generally obtained through the polymerisation of a number of basic molecules (monomers) to form long chains. We speak of homopolymers if a single type of monomer is used, copolymers if two or more different monomers are used, and polymer alloys if the material is obtained by mixing two monomers that polymerise without combining chemically.<\/p>\n

To this polymer base, various substances (called \u201cfillers\u201d) are then added depending on the application the plastic is intended for. These substances can be plasticisers, dyes, anti-oxidants, lubricants and other special components that give the finished plastic material the desired properties of workability, appearance and strength.<\/p>\n

The advantageous characteristics of plastics over metallic and non-metallic materials include greater ease of processing, cost-effectiveness, colourability, acoustic, thermal, electrical and mechanical (vibration) insulation, corrosion resistance and chemical inertness, as well as water-repellence and invulnerability to mould, fungus and bacteria.<\/strong><\/p>\n

An analysis of plastic families and materials is given below.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1678732173253{padding-top: 2em !important;}”][vc_column][vc_column_text]<\/p>\n

\n\t\t\t\tSono dette termoplastiche quelle materie plastiche che acquistano malleabilit\u00e0, cio\u00e8 rammolliscono, sotto l\u2019azione <\/span>\n\t\t\t\t[…]<\/span>\n\t\t\t\tdel calore. In questa fase possono essere modellate o formate in oggetti finiti e quindi per raffreddamento tornano ad essere rigide. Questo processo, teoricamente, pu\u00f2 essere ripetuto pi\u00f9 volte in base alle qualit\u00e0 delle diverse materie plastiche<\/span>\n\t\t\t<\/div>\n\t\t\t
