| Trexlink ™ 4790 is a highly engineered Thermoplastic Elastomer for use in applications requiring integrally colored material. This material is UV stabilized and can be pre-colored in most Automotive Interior or other colors. It can be easily processed by injection molding, blow molding or extrusion. Applications include critical color matched Automotive components such cup holders, mats, seals, soft seat trim. Also works well for two-shot molding or over-mold components such as grips and handles. |
