ELASTOMERS & REPAIR KITS

VITON®

is an elastomer with good corrosion resistance to a

wide variety of chemicals. Temperature range -40°F

to 350°F (-40C to 177C).

PTFE (POLYTETRAFLUOROETHYLENE)

is a thermoplastic polymer that is inert to most

chemicals. Similar in chemical resistance to Teflon

Temperature range 40°F to 220°F (4C to 104C).

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 (-12C to

82C).

GEOLAST®

is an injection molded thermoplastic material with

characteristics similar to Nitrile. Has excellent

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

(-12C to 82C).

EPDM

is a general purpose elastomer with good resistance

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

to 280°F (-40C to 138C).

SANTOPRENE®

is an injection molded material with characteristics

similar to EPDM. Has excellent abrasion resistance.

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

FKM

is an elastomer with good corrosion resistance to

a wide variety of chemicals. Similar in chemical

resistance to Viton

. Temperature range -40°F

to 350°F (-40C to 177C).

WETTED ELASTOMERS

II 2 GD c TX

Warning: The TX marking refers to the maximum surface temperature depending not on the equipment itself, but mainly

on operating conditions. In this case, the maximum surface temperature depends upon the temperature of the process

fluids.
