The Megol family of TPE compounds offers the ideal combination of the elasticity, look and feel of rubber with the low processing costs of thermoplastics. The formulation flexibility of this polymer allows the production of grades with a very wide hardness range, suitable for a variety of applications. They are ideal for injection and extrusion moulding, and are also available in grades which are nontoxic and/or for food use. The dominant matrix of these elastomer compounds is the thermoplastic block copolymers which belong to a number of different polymer families. Typically the Megol family belongs to the styrenic class of block copolymer (SEBS, SEPS) with a hydrogenated mid-block. However there are grades of the product based on polymers of other origin. The hydrogenation process removes the double bonds in the material which is what gives these compounds their high levels of performance such as excellent age and UV light resistance.
These products are particularly well-suited to over-moulding and extrusion and have a rigid substrate which provides their soft-touch characteristics and general similarity to rubber.
