The Plastic is an organic substance of high molecular weight.
Features of Plastic:
- It consist of natural and synthetic binders with or without fillers, plasticizer, solvents.
- They are divided into two types depending upon their behaviour when heated and cooled during manufacture.
- Those two types are Thermoplastic and Thermosetting plastic.
- Thermoplastics are formed by polymerization process by addition.
- Thermosetting plastics are formed by polymerization process by condensation.
Properties of Plastics:
Properties of plastics are as follows:
- Firstly, it offers great resistance to moisture, chemicals and solvents.
- It is not ductile in nature. As a result its members may fail without warning.
- Above all Plastic is durable and highly resistant to corrosion.
- In addition it possess excellent electric insulating property.
- It is easy to maintain plastic surface. Therefore, does not require any protective coat of paints.
- Lots of them are transparent and translucent. Hence it possess optical property.
- Moreover thermal conductivity of it is low.
- Lastly, Plastics like phenolic resins are resistant to weather effects.
Uses of Plastics:
- There are number of different types of plastic available in the market. As a result, its performance is excellent rather than rubber or steel.
- The Group of typical uses of it in building are as follows:
- Firstly for Decorative laminates and mouldings
- Secondly for Electrical Conduits
- Thirdly for Paints and Varnishes
- Fourthly for Foams for thermal insulation
- Electrical conduits
- Films for water proofing; damp-proofing
- Jointless flooring
- Water resistance adhesives
- Lighting Fixtures
- Floor Tiles
- Roof Lights
- Safety Glass
- Lastly for Bath and sink units.
