PLASTIC, TEXTILE, STONE AND CERAMICS MATERIALS

PLASTICS

Plastic or polymers. Polymerisation

Origin of plastic: Natural (very few) and Sinthetic (from petroleum, natural gas and carbon)

Properties of plastics: malleability, ductility, low density, insulation properties, impermeability.

Not biodegradable but we can recycle them.

Classification in 3 groups:

• Thermoplastic: PET, PVC, PS, PP, LDPE, HDPE, PMMA, Teflon, nylon objetcs and their symbol to recycle.
• Thermostable: you can only shape once. If you heat more times they degrades but you cannot shape again.
• Elastomers:rubber (natural and synthetic). Made with vulcanitasion.

FORMATION TECHNIQUES

Extrusion, Lamination, Vacuum forming, blow moulding, injection moulding, compression.

TEXTILES.

Vocabulary: thread, fabric, cloth, cotton, linen, silk, hemp, wool,

• fibre of vegetable, animal or mineral origin.
• fibre of synthetic origin: polyester, rayon, nylon, lycra

STONE AND STONE AND BINDERS.

Vocabulary: marble, granite, slave, sand, gravel, waterproof, plaster, cement, mortar, concrete.

CERAMICS AND GLASS.

How we made ceramics and glass. Properties of glass.
