Polyethylene
Polyethylene is one of the most widely produced plastics in the world. It comes in a variable crystalline structure that gives the material a wide range of physical characteristics. Generally, as the crystallinity increases the density classification increases. The higher density material becomes more stiff and rigid.

Polycarbonate
Polycarbonate is durable, moldable, and lightweight and is shatter proof. Although made commercially available in a variety of colors, the raw material allows for the internal transmission of light nearly in the same capacity as glass. Polycarbonate polymers are used to produce a variety of materials and are particularly useful when impact resistance and/or transparency are a product requirement (e.g. in bullet-proof glass).
PC is commonly used for plastic lenses in eyewear, in medical devices, automotive components, protective gear, greenhouses and exterior lighting fixtures. Polycarbonate also has very good heat resistance and can be combined with flame retardant materials without significant material degradation.
Properties:
High rigidity
Excellent impact strength
Good chemical resistance and electrical insulation properties
Typical Applications:
Pipe, packaging, refrigerator liners, conduit
ABS
ABS is derived from acrylonitrile, butadiene, and styrene. The most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. It is widely used for machining pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue.
