Plastics / Resins
Tough, strong, retains it’s dimensions at elevated temperatures,
excellent resistance to most organic solvents and good resistance to
strong acids and bases, naturally opaque.
(perfluoroalkoxy)Translucent, flexible. Cryogenic to 260oC,
autoclavable, chemically inert, non-contaminating, very easy to clean
as almost nothing adheres.
withstands extreme temperatures, cryogenic to 180oC , non-burning and
||Polymethyl methaacrylate (acrylic)
Transparent (very clear) –60 to 70oC, resistant to inorganic acids and
alkalis but not to organic solvents
white, translucent, slightly flexible, greater chemical and temperature
resistance than TFE and FEP
180 to 180oC autoclavable, attacked by strong oxidizers, softened by
some hydrocarbons and chlorinated solvents.
tough, resists abrasion, fatigue and impact. Excellent resistance with
organic solvents but not with mineral acids, oxidizing agents and
Translucent form very flexible, opaque is rigid.. –25
to 80°C, poor resistance to most solvents, very good resistance to
oils (except essential oils), low gas permeability.
||Teflon FEP (fluorinated ethylene propylene)
Translucent.flexible,resists all known chemicals except
molten alkali metals and elemental fluorine.Can even be boiled with
Translucent to transparent, fairly rigid. –10 to
130°C resistant to most chemicals except strong oxida
||Fluorinated high-density polyethylene
Transparent (toughening agent makes opaque) –30 to 60oC,
resistant to most aqueous solutions and organic solvents.
Transparent to opaque, fairly rigid. –50 to
110oC, autoclavable, chemical resistant.
Clear, strong , extremely tough.resistant to acids, bases,
aqueous solutions,aliphatic hydrocarbons and alcohols.
Translucent, flexible.-50 to 80oC, resistant to most
chemicals except strong oxidants.
non toxic,crack and stress resistant, robust,high purity apps.
Autoclavable Combines some of the advantages of ethylene
and ropylene.High temperature performance and low temperature strenght
Opaque white, extremely pure, superior for non-contaminating
applications.good mechanical strength and abrasion resisance up to
100°oC Similar to ECTFE
–190 to 130°C, autoclavable but mechanical properties
impaired, attacked by some concentrated acids, alkalis,
and organic solvents.
Opaque, semi- rigid, low coefficient of friction,-200 to
260°C, autoclavable, excellent chemical resistance to all reagents.
||Poly (1,4 cyclohexane dimethylene
can be moulded into autoclavable parts and rubber-like small
caps and plugs
||Polyethylene terephthalate copolyester
Glass-like clarity, tough. Excellent gas-barrier, choice
for storing biologicals.can be sterilised but cannot be autoclaved.
||Cross-linked high-density polyethylene
Three dimensional polymer of extremely high molecular
weight, superior stress-crack resistance, used for moulding very large
