Cray Valley Ricon® 181 Low Vinyl Butadiene-Styrene Copolymer
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Styrene Butadiene Rubber
Material Notes:	Description: Ricon® 181 is a low molecular weight, liquid copolymer of butadiene and styrene. This resin is suitable for use in peroxide- and sulfur-cured elastomers where it acts as a non-extractable plasticizer and process aid. Its polymeric structure gives excellent compatibility in saturated and unsaturated elastomers, especially elastomers with styrenic and aromatic content. Product Highlights / Performance Properties: Non-extractable process aid Electrical insulator Excellent dielectric properties Excellent hydrophobicity Low temperature flexibility Excellent compatibility with elastomers Suggested Applications: Coatings Electronics Laminates Encapsulants Rubber Flexographic printing plates Information provided by Cray Valley
