Types of plastic
- polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles
- polystyrene (PS) found in computer cases
- polypropylene (PP) found in dishwasher safe containers
- polyethylene terephthalate (PET) found in soda bottles
- polyvinyl chloride (PVC)
More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics
These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn
This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds
