Waterford, New York – Momentive Performance Materials Inc.’s Silopren LSR (liquid silicone rubber) RSH (reduced self-healing), a liquid silicone rubber in the Silopren product family, is capable of providing significantly reduced self-healing of valve slits and offers potential benefits to a wide range of valve and fluid-flow products in the medical, food, and infant care industries.
Silicone slit valves often experience sticking or self-healing issues when subjected to harsh conditions. On 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 increases the cost to manufacturers but also the risk of contamination of the products. Momentive’s new Silopren LSR RSH series has improved material properties that can help solve the self-healing issue of slit valves.
“Momentive is a pioneer in LSR technology and we continue to address our customer’s manufacturing challenges by developing innovative materials that improve product performance,” said Tina Wei, global marketing director, Consumer Goods Elastomers. “This addition to our robust Silopren LSR product portfolio offers significant material improvement for specialized food contact and medical device applications.”
