B. Thermosets
- Heated melt
- Cooled → does not return the original kesifat
Example: polyurethane, epoxy, elastomer
but that dipake Polyethylene
- Having the flexibility at room temperature and low temperature
- In-water
- Resistant to chemicals
- Can be connected with heated (soldered)
- It can be colorful
Bottles are generally made from materials such as plastics and glass. Bottle-making process of both materials is almost the same. Material in the melting and then blown into a mold in accordance with the desired shape.
