Resilient Terephthalic Resin Introduced for Pultrusion

25 June 2007

Reichhold has introduced a new low-styrene, UV stabilized, resilient terephthalic resin, DION 31068-00, for the pultrusion market in the United States, Canada and Mexico.

Because this resin is based on terephthalic acid, Reichhold say that it should eliminate the cost and supply issues related to the on-going isophthalic acid shortages.

DION 31068-00 is a low-styrene, UV stabilized, medium-high reactivity, resilient terephthalic resin. It was developed as a performance match to UV-stabilized, resilient, isophthalic resin systems. The material was developed to yield a lower total cost structure for pultruders by enabling them to increase line speeds.

Reichhold says that this resin has a unique combination of both low viscosity with a low-styrene content. With a styrene level of 30% or less, it is compliant under California Rules 50 and 1162 and is also direct injection capable. Applications for DION 31068-00 include:

  • Window Lineals
  • Ladder Rails
  • Tool Handles
  • Fan Shrouds
  • Structural Shapes
  • Utility Pole Cross-Arms
  • Lower end Sheet Piling/Seawalls

DION 31068-00 is available only in the United States, Canada and Mexico at the moment.
