Dimethyl Esters: Elastomers and Plastics Compatibility

by | Mar 10, 2014

Elastomer and plastics compatibility is an important consideration when looking at storage and handling options for DMEs.

Many dimethyl ester (DME) end-users have requested more information about elastomer and plastics compatibility.

This typically concerns our Sta-Sol® solvents and how they interact with different types of containers, seals, gaskets, and other packaging or coating materials.

Fortunately, DMEs (and dibasic esters, or DBEs) are compatible with many different elastomers and plastics.

Compatible elastomers include:

  • neoprene
  • silicone
  • ethylene propylene polymers
  • styrene/butadiene
  • natural rubber

Compatible plastics include:

  • polypropylene
  • polyethylene
  • epoxy
  • teflon
  • Nylon 6,6

There are several materials that are not recommended for use with DMEs, as the esters will swell, dissolve or otherwise degrade these materials.

Incompatible elastomers include buna-N rubber (NBR), fluoroelastomers and polyurethane.

Plastics not recommended for use with DMEs include polycarbonate, cellulosic, acrylic, polystyrene, polysulfone, and polyvinyl chloride (PVC).

This is a general list, and we strongly recommend testing and further inquiry before using dimethyl esters with any of the included materials.
