Description
- Two-part, high clarity silicone system designed for use in injection molding equipment
- Cures with heat via addition-cure chemistry
- 1:1 Mix Ratio (Part A: Part B)
Applications
- For the injection molding of parts requiring a high clarity / high durometer material including: molded rubber stoppers, gaskets, seals, valves, o-rings and other precision parts
- Suitable for over-molding applications (may require use of a silicone primer for improved adhesion)
- Can be used with NuSil's Healthcare color masterbatches for applications requiring colored silicones
NuSil Technology's MED-4971 shall not be considered for use in human implantation for a period of greater than 29 days.
