PET - POLYETHYLENE

Polyethylene is a thermoplastic resin, it appears as a transparent solid (amorphous form) or white (crystalline form) with excellent insulating properties and chemical stability, it is a very versatile material and one of the cheapest plastic materials; the most common uses are as insulation for electric cables, agricultural film, plastic bags and envelopes, containers of various types, pipes, inner layer of aseptic containers for food liquids and many others.

POLYPROPYLENE

Polypropylene (or polypropene, abbreviated to PP) is a thermoplastic polymer that can show different tacticity. The most interesting product from a commercial point of view is the isotactic one: it is a semi-crystalline polymer characterized by a high breaking load, low density, good thermal and abrasion resistance.

PVC - POLYVINYL CHLORIDE

Pure, it is a rigid material; it owes its application versatility to the possibility of being mixed even in high proportions with inorganic compounds and plasticizing products, such as for example phthalic acid esters, which make it flexible and mouldable. It is considered stable and safe in technological applications at room temperature, but extremely dangerous if burned or heated at high temperatures and in systems unsuitable for its treatment, due to the presence of chlorine in the molecule, which can be released as hydrochloric acid

POLYSTYRENE

It is a thermoplastic aromatic polymer with a linear structure. At room temperature it is a glassy solid; above its glass transition temperature, about 100°C, it acquires plasticity and is able to flow; begins to decompose at a temperature of 270 °C.

Expanded polystyrene comes in the form of a light white foam, often molded into spheres or chips, and is used for packaging and insulation.
