Dexco Polymers Introduces New Copolymers for Hot Melt Adhesive Market

Dexco Polymers LP has developed styrene-isoprene-styrene block copolymers (SIS) that can be used in demanding hot melt adhesive (HMA) and pressure sensitive adhesive (PSA) applications at reduced polymer loads. Vector® DPX 618 and DPX 619 are new 4-arm radial block copolymers that allow formulators to achieve desired adhesive performance while using less polymer in the adhesive formulations.

DPX 618 is a high styrene, SIS block copolymer designed for non-woven applications, such as an elastic attachment adhesive, where high temperature shear resistance is required. DPX 619 is a lower styrene version designed for PSA and adhesive applications that require lower shear resistance at elevated temperatures. “Dexco Polymers has been focusing its R&D resources on inventing new polymers that offer lower cost solutions to the adhesive market,” said Chris Mudd, General Manager Dexco Polymers. “By using up to 25% less polymer for the same adhesive performance, these patented 4-arm radials offer substantial savings to the adhesive formulator.” These new products are well suited for a wide range of applications as they do not use TNPP antioxidants.
