PLASTICS
-
Properties
Composition (strength, elasticity, rigidity, flexibility)
Other (mechanical, acoustic, electrical, thermal...)
Ecological properties
Chemical recycling, to make new materials.
-
Energetic recycling, for heatin or producing electricity.
Classification
Thermoplastics, acquired from petroleum.
Thermostable plastics (polyurethane, phenolic resins, melamine formaldehyde, polyester resins)
Elastomers (natural rubber, synthetic rubber, neoprene)
Formation techniques
Extrusion. Used to form: wrappin, cables, lining for electric, tubes and pipes.
Lamination. Used to form: worktops, to cover surfaces of kitchen cupboards and drawers.
Vacuum forming. Used to form: bathtubs, deshboards, shop sings and egg boxes.
Moulding
Ingection moulding. Used to form: domestic utensils shuch as buckets and containers, vehicle and aircraft components.
Blow moulding. Used to form hollow objets, for example bottles and flasks.
Compression Used to form: different types of containers, machine bodywork and electrical appliances.
-
Joining plastics
Temporary joints. (nut and bolt, standard screw, double ended screw)
Permanent joins. (joining two surfaces permanently, joining thermoplastics using heat and pressure)
Textiles and leather
-
Sinthetic fibres. (nylon, polyester, rayon and lycra)
Stone and ceramics.
Stone. (marble and granite, slate)
Stone binders. (plaster, cement, mortar, concrete)
Ceramics. (baked clay, earthenware, heat resistant material, stoneware, porcelain)
Glass. Is waterproof, resistant to environment and good termal
Shaping techniques (Mould blwoing, float glass making, lamination.)
