Definitions

Low Density Polyethylene (LDPE)
LPDE is a most useful and widely used plastic. It is translucent to opaque, robust enough to be virtually unbreakable and at the same time quite flexible.

High Density Polyethylene (HDPE)
A linear polymer prepared from ethylene by a catalytic process. It lends itself particularly well to blow molding, e.g. for bottles and containers.

Polypropylene (PP)
PP is a translucent material with excellent mechanical properties and it has gradually replaced the polyethylenes for many purposes.

Polystyrene (PS)
A hard rigid, transparent plastic with good dimensional stability.

Polymethylmethacrylate (ACRYLIC)
A rigid plastic with a high degree of transparency. It is resistant to inorganic, acids and alkalis but is attacked by wide range of organic solvents.

Polytetrafluoroethylene (PTFE)
PFTE shows a remarkable chemical resistance and it is insoluble in all known solvents.

>Polymethylpentene (PMP)
The important qualities of PMP as a laboratory plastic are its high transparency, its rigidity and resistance to impact and withstand temperatures of up to 200°C for short periods (180°C continuously).

Polyvinylchloride (PVC)
PVC has a linear structure similar to polyethylene but with a chlorine atom replacing a hydrogen atom on alternate carbon atoms.

Polycarbonate (PC)
PC is a linear polycarbonic acid ester prepared from a dihydric phenol.

Perfluoroalkoxy PTFE (PFA)
PFA is a copolymer of tetrafluoroethylene (CF2=CF2) with a perfluoralkyl vinyl ether [F(CF2)m CF20CF=CF2].
