Properties

Chemical Resistance

ABS
Acrylonitrile
Butadiene Styrene

Stable over a wide range of temperatures,
especially good in cold environments,high
impact strength and ductility, good
chemical resistance and rigidity.

Mostly resistant to solutions of salts,
inorganic acids, food acids and alkalines.
Not resistant to solvents,aromatics and
some chlorinated hydrocarbons.

Corzan PVC-C
Post-chlorinated
Polyvinyl Chloride

Excellent chemical resistance, good
mechanical strength and rigidity, high heat
resistance,excellent flammability properties
(self-extinguishing), low thermal conductivity
and good abrasion resistance.

Resistant to many acids, bases, salts,
paraffinic hydrocarbons, halogens and
alcohols.Not resistant to solvents,
aromatics and some chlorinated
hydrocarbons.

+100˚C

ECTFE
Ethylenchlortrifluoretylene
(Halar)

Excellent mechanical and chemical
resistance, fire retardant, wideoperating
temperature range, very good
weathering resistance.

Resistant to most acids, alkalis, salts,
halogens, alcohols and chlorinated
hydrocarbons, especially good with
caustics andchlorine solutions.

+150˚C

PC
Polycarbonate

Excellent combination of toughness,
transparency, heat and flame resistance
and dimensional stability. Good electrical
insulating properties andwide operating
temperature range.

Generally unaffected by greases, oils and
acids. Not resistant to solvents, esters and
ketones, which can cause cracking.
Continuous exposure to hot watercauses
embrittlement.

+135˚C

PEEK
Polyetheretherketone

Very high operating temperatures, high rigidity
and hardness, strength and thermostability.
Very good chemical resistance, gooddielectric characteristics, self-extinguishing
and resistant to radiation.

Very good resistance to most solutions.
Not resistant to concentrated sulphuric
acid, fuming nitric acid and some halogen...
