- THERMOPLASTICS (separate chains of polymers)
- STRUCTURE
- THERMOPLASTIC MATERIALS (plastics that are softened by
heating, can be formed and melted as many times as we like)
- POLYRTHYLENE (PE) most common type of plastic. Offers good
chemical resistance. Non-toxic, sustainable for food packaging
- POLYSTYRENE (PS) very lightweight, transparent plastic.
Expanded polystyrene is widely used in packiging and for heat
insulation.
- PVC (POLYNINYL CHLORIDE) highly resistant to abrasion and
impact
- POLYPROPYLENE (PP) plastic easy to model and dye. Resistant
to solvents and splintering
- PET (POLYETHYLENE TEREPHTHALATE) sustainable for
food use, this plastic is completely recyclable,
transparent and easy to dye
- >
- >
- TEFLON highly resistant to chemicals and high
temperatures. Excellent non-stick properties.
- POLYCARBONATE (PC) highly resistant to impact and
heat. Good optical transparency.
- NYLON: exceptionally strong and elastic. Excellent toughness,
abrasion resistance, easy to wash and to dye

- STRUCTURE
- THERMOSERS (CRISS-CROSSED POLYMER CHAINS)
- STRUCTURE
- THERMOSET MATERIALS (plastics can be shaped using heat, but once
they've been formed they can't be re-melted to create different forms)
- MELAMINE resistant to high temperatures and chemicals. Easy to
clean.
- BAKELITE a hard and brittle, dark plastic that withstands heat
very well
- >
- >
- POLYESTER RESINS rigid and brittle, usually strenghned with fibreglass
- PHENOLIC: superior mechanical strenght, heat resistance.
Resistance against various solvents, acid and water.

- MELAMINE resistant to high temperatures and chemicals. Easy to
clean.
- STRUCTURE
- ELASTOMERS (coiled polymer chains)
- STRUCTURE
- ELASTOMER MATERIALS (very flexible materials thet recover their shape and dimensions when external forces
stop acting on the them. They degrade easily with the heat and can't be re-melted once they've been once
formed)
- RUBBER: can be natural or synthetic. It's elastic.
- NEOPRENE: flexible, insulated and waterproof.
- >
- >
- SILICON: heat resistant
- POLYURETHANE: resistant to water, electrical
properties

- RUBBER: can be natural or synthetic. It's elastic.
