NuSil MED-4174 Silicone, One Part High Consistent Elastomer - Restricted Medical Use

Description: HCRs can be used for extrusion of tubing and profiles (rod or ribbon), in calendared sheeting for die-cutting, or in compression or transfer molded parts such as balloons, gaskets or o-rings. HCRs are clay-like in the uncured state and when cured generally exhibit very high mechanical properties and low modulus.

Important Properties: HCRs with a peroxide cure system have a long history in implant applications. The cure mechanism can be vinyl specific or non vinyl specific. Non vinyl specific peroxide catalysts are more commonly used with HCRs than vinyl specific peroxide catalysts. Features of peroxide cure high consistency rubbers include the following:

• One or two part
• Indefinite work time
• Heat required
• Acid or alcohol byproducts
• Post cure required
• % shrinkage ~2 -5%

Comments: Uncatalyzed

Cure System: Peroxide
