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.
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.
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.
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].

*Warning:These charts
are general guidelines only. Customers should consult a reputable source prior
to using a specific chemical with a specific plastic part. Ratings of chemical
behavior listed in this chart apply at a 48 hr exposure period; Daigger has
no knowledge of possible effects beyond this period. Use suitable guards and/or
