Petroleum
It’s a fossil fuel formed from the remains of marine organisms+ heat+pressure+time. Measure in barrels
PROCESS: extraction+refinery+transport
Transform into diesel, gasoline….
What is a polymer?
A polymer is a sustance formed by the union of basic molluscs called monomers. (Long chains of monomers)
Types of polymers:
Synthetic poly (petroleum) Natural poly (nature)
Types of plastics:
Thermoplastics, thermoset and elastomers
Termoplástica:
Made up of long lineal chains of polymers
Easy to break by heat ang get back
Melted and reshaped.
Easy to recycle.
Classification of terplastics:
1- pet (agua) 2- HDPE (leche) 3- PVC (tuberías) 4- LDPE (bolsa) 5- PP (maceta) 6- PS (yogurt) 7- OTHER (Plato)
Thermoset
NOT RECYCLE
SHAPED ONCE
FORM BY HEAT AND PRESSURE
Types of thermoset
1- bakelites (placas) 2- polyesterressins (pool) 3- pelamine ressins (table) 4- polyretnanes (construction) 5- epoxy ressins (patio)
Elastomers
Termosetting polymers are elastomers.
Elastic
Can’t recycle
Excelent traction
