M.A. Hanna Co. of Cleveland offers two styrene block copolymers. Hanna claims its styrene butadiene styrene material is a true tri-block copolymer. It has high tensile strength, processing stability and resists heat-aging. Its styrene ethylene butylene styrene polymers are hydrogenated styrenics with good ultraviolet light, ozone and chemical resistance. The SEBS grades are available in hardnesses from 30 Shore A to 50 Shore D and melt flow rates of 0.3-50.

New Talaurian ink designed for TPEs
Talaurian Technologies Inc. claims its new, patented ink for-mulation allows permanent decorations on a range of thermoplastic elastomers without pretreatment of the elastomer.
The ink gives a stretchable and durable imprint in a range of colors in the injection mold or during post-mold operations in a one-step process. The ink, which chemically bonds to the substrate, is cost-competitive with hot-stamp labels, according to the Newport Beach, Calif., firm.
