PLATINUM CURE
Platinum cure high consistency rubbers (HCRs) have the consistency of clay and well-suited for fabrication processes such as extruding, calendering and compression or transfer molding into a wide range of parts.
Applications
NuSil HCRs can be used to extrude rod and ribbon profiles and tubing for medical applications. They can also be calendered into sheets for die-cutting or molded into parts, such as balloons, gaskets and O-rings.
Key properties and considerations
‒ Green strength: ideal for extrusion processes
‒ Very high mechanical properties and low modulus compared to other elastomer systems
‒ Two-part curing system
‒ No byproducts generated from the curing process
‒ Post-cure is optional
PEROXIDE CURE
Peroxide cure high consistency rubbers (HCRs) have a long history in implant applications and are similar in consistency to platinum cure HCRs. NuSil offers peroxide cure HCRs in both uncatalyzed and pre-catalyzed forms.
Uncatalyzed
NuSil uncatalyzed peroxide HCR systems offer the flexibility of using your preferred peroxide catalyst. They do not contain vinyl- or non-vinyl-specific peroxide catalysts as supplied.
Pre-catalyzed
Our pre-catalyzed peroxide curing HCRs are one-part systems that contain a dichlorobenzoyl peroxide catalyst and are ready for use.
Key properties and considerations
‒ Green strength: ideal for extrusion processes
‒ Indefinite work time
‒ Low modulus compared to other elastomer systems
‒ One- or two-part systems available
‒ Heat required to cure
