ELASTOMERS 

WETTED ELASTOMERS

FKM 

is an elastomer with good corrosion resistance to a 

wide variety of chemicals. Temperature range  -40°F 

to 350°F (-40°C to 177°C).

Most of the above elastomers are available in FDA 

approved formulations.

BUNA-N (NITRILE)

is a general purpose elastomer used with water and 

many oils. Temperature range 10°F to 180°F (-12°C 

to 82°C).

GEOLAST® 

is an injection molded thermoplastic material with 

characteristics similar to Nitrile. Has excellent  

abrasion resistance. Temperature range 10°F to 180°F 

(-12°C to 82°C).

EPDM 

is a general purpose elastomer with good resistance 

to many acids and bases. Temperature range  -40°F 

to 280°F (-40°C to 138°C).

SANTOPRENE® 

is an injection molded material with characteristics 

similar to EPDM. Has excellent abrasion resistance. 

Temperature range -40°F to 225°F (-40°C to 107°C).

PTFE (POLYTETRAFLUOROETHYLENE)

is a thermoplastic polymer that is inert to most 

chemicals. Temperature range 40°F to 220°F (4°C to 

104°C).
