Message
Elastocon® STK40 is a colorable thermoplastic elastomer that has been developed for applications that require ultra soft rubber-like properties and a good surface finish. Elastocon® STK40 is FDA compliant and well suited for consumer goods and industrial applications requiring non-slip/soft touch ergonomics, sound and vibration dampening, improved impact resistance, and U.V. stability. Elastocon® STK40 can be overmolded to PC, ABS, PC/ABS, Acrylic, HIPS and copolyester.

Injection instructions
Elastocon® thermoplastic elastomers are shear dependent and have been formulated to process on conventional thermoplastic equipment for injection molding, extrusion or blow molding. Our tests have shown that overmolding onto a non-gloss, matte surface finish will help optimize overmold adhesion to the substrate. Be sure to incorporate mechanical interlocks and 1:1 through holes whenever possible when designing two shot components. Feathered edges should always be avoided to ensure adequate and consistant shut off against the substrate, while also eliminating exposed tapered edges that can be subject to adhesive failure.Injection Rate: 1 to 5 in/sec
