Elasto to show 2-K moulding adhesives at Fakuma

ERJ staff report (DS)

Friedrichshafen, Germany -- At this year's Fakuma exhibition Elasto will showcase the latest developments in their Dryflex and Mediprene adhesion products for overmoulding and co-extrusion applications.

When co-extruding or overmoulding with soft components, the surface of the hard component softens and a diffusion of the molecules in the outer layer takes place. This stage is critical for the quality of the bonding between the soft and hard material and is called cohesive bonding. Generally the bonding strength depends on the two chosen materials. Dryflex grades can be co-extruded or overmoulded with a wide variety of engineering plastics including PP, PE, PA, ABS, PC, PS, PMMA, ASA, SAN and their blends. Polyamides and ABS may be either reinforced or non-reinforced yet still bond well to Dryflex TPEs.

Dryflex A compounds offer UV, ozone and weather resistance with service temperatures from minus 40 C to 125 C. They are particularly successful in applications where good sealing performance is required, such as food containers or seals on white goods.

The Mediprene A series were developed specifically for medical device applications. They follow Elasto's stringent Mediprene raw material selection policy; the elastomer is chosen from a series where representative grades have passed USP Class VI, the paraffinic oil is medicinal white oil complying with European Pharmacopeia and the plastic component is a medical grade that has passed USP Class VI.
