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.
