Eastman Endex™ 155 Hydrocarbon Resin
Categories:	Polymer
Material Notes:	Product Description: A water-white thermoplastic resin made from purified aromatic hydrocarbon monomers. Used to modify the melt flow and increase the temperature resistance of styrenic plastic and rubber. Reinforces the styrene end blocks of styrenic block copolymers. In adhesives Endex™ 155 hydrocarbon resin will associate with the styrenic endblocks, producing higher cohesion at temperatures up to 70°C without affecting tack and adhesion properties. Application/Uses: Assembly Automotive Building and Construction Caulks and Sealants Hot Melt Adhesives Nonwovens Pressure sensitive adhesives Rubber and Plastic Modification Solventborne Adhesives Tapes and Labels Key Attributes: Heat stability Pure aromatic monomer composition Very high softening point Water-white initial color Information provided by Eastman
