Thermoplastics VS Thermosets













Plastic most of times replaces wood, metal and glass because of its versatility. However, plastics are still a young discovery, and still being a very innovative material to use if we have in account the history of construction. Limitless are the qualities of this material, a plastic can be selected for its strenght, impact resistance, scratch resistance, ultraviolet resistance, transparency, reflection, insulating properties.

Thermoplastics:

- Thermoplastics are temperature-sensitive
- They disolve or soften in solvents
- Thermoplastics are generally softer
- They can melt or burn

Ex's of thermoplastics: Plexiglas, Makrolon and Lexaan, PVC, Polysterene, Polypropylene and polyethene.

Thermosets:

- Less temperature-sensitive than thermoplastics
- They do not dissolve
- They are harder, less elastic
- Thermoplastics don't melt or burn, or at least they are harder to burn.

Ex's of thermosets: Bakelite, epoxy, polyester

I may emphasize more in one of these particular materials on following posts.
