DCPD Products
ULTRENE™ 99 DCPD and ULTRENE™ 97 DCPD are ultra-high purity dicyclopentadiene (DCPD) products providing the highest purity DCPD available to the industry.

Due to their ultra-high purity, ULTRENE™ DCPD products provide greater value and enhanced cost-performance. With ULTRENE™ DCPD products the customer receives more DCPD per unit of volume and significantly much less by-products and diluents compared to other DCPD grades in the industry.

Due to their ultra-high purity, ULTRENE™ DCPD products impart improved processing and enhanced properties in applications using dicyclopentadiene due to:
less waste in processing
DCPD-CPD Trimer Products
ULTRENE™ 99-X DCPD products are 99% purity dicyclopentadiene (DCPD) product containing X% cyclopentadiene (CPD) trimer. The CPD Trimer content is available from 6% to 20% depending upon the customer's needs. In addition to the superior toughness, durability, electrical, mechanical, and hydrolytic resistance properties obtained from ULTRENE™ 99 DCPD, the CPD Trimer imparts a significant increase in the heat distortion temperature (HDT) of the cured resin or polymer with some increase in rigidity.
Co-Products
Resin Former Prime, Resin Former and Resin Oil Heavies are co-products from the production of ULTRENE™ DCPD products.
Resin Former Prime is a mixture of reactive aromatic diene species from petroleum distillate. Products of this type are often referred to as C9 Resin Oil since it contains essentially no cyclopentadiene compounds.
