Baypren 223 polychloroprene Bayer Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE >> Solvent based Poly-2-chlorobutadiene-1,3 Baypren 223 is a chloroprene rubber with a medium rate of crystallisation which gives solutions of medium viscosity and meets the special requirements of the adhesives industry. As Baypren 223 is not modified with sulphur or thiuram, it is particularly suitable for adhesives with minimal discolouration tendency. Flat chips, powdered with talc to maintain the free-flowing properties (powder content max. 1 %). polychloroprene for the production of adhesives with a long open time and high initial strength. Poly-2-chlorobutadiene-1,3. Polychloroprene rubber with a medium rate of crystallisation for the production of solventborne adhesives with minimal discolouration tendency and a long open time and high initial strength. Gives solutions with medium viscosity. Not modified with sulphur or thiuram.
