  Santoprene Chemical Resistance:

     
 


Santoprene is a thermoplastic rubber designed to offer chemical resistance equivalent to neoprene.  It is resistant to a wide variety of solvents and chemicals.  It is not readily soluble in common solvents but will swell in aromatic solvents and halogenated organic solvents.

 

High polar fluids such as alcohols, ketones, glycols, esters, and aqueous solutions of acids, salts, and bases have little effect upon Santoprene rubber.  Weight changes in these fluids are less than 10%, and physical property changes are minimal.

  Vari-Com Chemical Resistance:

     
 


This is a chemically resistant fluoropolymer.  It is injection-molded and has chemical resistance similar to Teflon.  Care should be taken when heating Vari-Com plates when filled with organic solvents.  The Vari-Com material is stable from –80C to +140C but if filled with some organic solvents the plastic becomes distorted at high temperatures.  It is not recommended that temperatures higher than 60C be used in conjunction with solvents.  It has very low extractables when tested using HPLC compared to Polypropylene.

 

All of the solvents below are chemical resistant when stored at room temperature.

     
   

Acetic Acid
Acetone
Ammonium hydroxide
Chloroform
Dichlromethane
