Momentive Performance Materials (Momentive) will introduce Silopren* LSR RSH (Reduced Self-Healing), a liquid silicone rubber in the Silopren product family at Fakuma 2015 October 13-15. The Silopren LSR RSH series can reduce self-healing of valve slits and offers potential benefits to a wide range of valve and fluid-flow products in the food, medical and infant care industries.
Silicone slit valves often experience sticking or self-healing issues when subjected to harsh conditions. For medical devices such as needle-free infusion systems, a risk with valve healing is decreased dose precision of liquid or fluid. The slitting design in both medical and food applications presents a challenge for manufacturers who often have to add a non-stick surface treatment to facilitate separation of the slit surfaces or provide special handling and storage instructions for valve opening. This not only contributes to manufacturing costs but also increases the risk of product contamination. Momentive’s new Silopren LSR RSH series has improved material properties that can help solve the self-healing issue of slit valves.
