Total Cray Valley industrializes sustainably sourced Krasol diols

Total Cray Valley is expanding its hydroxyl-terminated diene resin portfolio with the industrial introduction of sustainably sourced farnesene-based resins, Krasol F3000 and Krasol F3100. The Krasol product line is known in the market as a source of well-defined hydroxyl-terminated liquid poly(butadiene) diol and monol grades. These materials are used in a variety of end-use applications as components in urethane, epoxy and UV-cured adhesive and sealant formulations for the automotive and electronic markets. The diene backbone incorporates hydrophobic quality and chemical resistance, as well as elastomeric softness and low-temperature performance.

Damping materials based on liquid poly(butadienes): Structure-property relationships

Liquid poly(butadiene) resins can be defined as oligomers with a degree of polymerization (Dp) of 100 and molecular weights below the critical molecular weight. These materials have rheology defined as viscous flow at temperatures of less than 60°C. In this regime, properties such as glass transition temperature and viscosity are determined by both microstructure and macrostructure. In applications such as adhesives, thermoplastic modification or tire compounding, liquid poly(butadienes) are often used as high value additives, imparting specific performance enhancement
