Cray Valley Ricon® 156 High Vinyl Homopolymer of Butadiene
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: Ricon® 156 is a very low molecular weight, liquid polybutadiene resin with high vinyl functionality for high reactivity, exceptional hydrophobicity and excellent processing characteristics. This resin is suitable for use in peroxide- and sulfur-cured elastomers as a non-extractable plasticizer and process aid, where low viscosity and good reactivity are desired. Its polymeric structure gives excellent compatibility in saturated and unsaturated elastomers, especially olefinic-based elastomers and thermoplastic resins. The resin is a Type II coagent, giving excellent crosslink densities without affecting the rate of cure. Product Highlights / Performance Properties: High reactivity Non-extractable process aid Electrical insulator Excellent dielectric properties Excellent hydrophobicity Low temperature flexibility Coagent for elastomer cure Good hardness Scorch protection Good compression set Abrasion resistance High tear strength Suggested Applications: Coatings Electronics Encapsulants Rubber Wire and cable Sealants Thermoplastic modification Information provided by Cray Valley
