Your glycol of choice for high performance polyester resins

Synthomer’s butyl ethyl propanediol (BEPD) is the ideal diol for the synthesis of saturated and unsaturated polyesters. BEPD is a branched aliphatic diol with primary OH groups. Its branched structure offers a reduction in crystallinity, increased hydrophobicity and improved compatibility of the polymer.


Also available as liquid BEPD 70L (70% BEPD, 25% NPG, 5% water).

Synthomer’s 2-butyl-2-ethyl-1,3-propanediol will bring the following benefits to your high performance resins.

  • Improved hydrolytic stability
  • Reduction in crystallinity and brittleness
  • Improved yellowing resistance and gloss retention
  • Increases compatibility
