1. Poly vinyl chloride (PVC)
In case of PVC plastic is not very chewy and hard, but if it become soft PVC will be plexible and mengaret, the good properties of PVC which gives the dimensions of the stable and the other is its resistance to water, acids, alkalis and other solvents.
Usage:
- Nature stiff (rigid) and PVC can retain its shape is suitable for use on a variety of casting materials (Moulding).
- Plexible nature of PVC very well be used as surface coatings as well as coatings leak. PVC is also used as a pipe, duct and cable boxes, as well as material safety helmet pelapiss chemical tanks.
- Polytetraflouroethylene (PTFE or Teflon)
Teflon is very supple and flexible and superior in heat resistance where Teflon is not flammable, can not be attacked by a variety of reaction solvent and good electrical insulating materials, low coefficient of friction at a relatively cheap price.
Usage:
As the bearing (Bearing), fuel pipes, gaskets and tape, as well as chemical equipment where PTFE is very resistant to chemical pengruh.
Polyamides (Nylons)
- Polyamides (Nylons) are very strong and resilient yet flexible, resistant to abrasion and dimensional stable, Nylon can reduce water and solvents in general, has good properties as electrical insulating materials (Electrical insulation.
- Polyamides (Nylons) will deteriorate if placed in the open.
Usage:
Nylon gears are used as materials, Valves, completeness power tools, handles, knobs, bearings, cams, Shock absorber, Combs, wrapping bandages and medicine, raincoats, lint brush, grout and textile.
- Phenol formaldehyde (Bakelite)
- In the raw state Phenolic very fragile, by karenannya be mixed with fiber materials to increase the strength and nature of diversification will be obtained depending on the nature of the material composition asaalnya added. Objects made of this material will be brittle if the shape / size of the object is very thin.
- Bakelite absorb water but resistant to alcohol, oil and other solvents. Formation but not through a solidified melting at temperatures of 2000C.
Usage:
Electrical equipment, Tobol, handles, radio boxes, furniture (furniture), vacumm Cleaner parts, cameras, cigarettes assbak, automotive electrical fittings and other applications such as decoration, ornament, coating materials even gears, bearings aircraft equipment as well as equipment health, clutch linings and brake the vehicle.
- Polyethylene
Polyethylene (Polythene) is one of a kind Thermoplastic versatile because of its special supple and flexible on any changes of temperature range and stability memperrtahankan dimensions. Another trait of Polyethylene (Polythene) is very easy to print and resistant to various types of elements are also resistant to moisture solvent weather, but for long periods of time tiddak resistant to light.
