APPLICATION BULLETIN Resilience™ HC for Medical Device Housings Offering Improved Resistance to Hospital Disinfectants EFFECT ON POLYMER HOUSINGS FOR MEDICAL DEVICES Unfortunately, the increased disinfection practices among healthcare providers have another effect. Rigid polymers typically used to make housings for medical devices are failing to resist these chemicals. The consequences to the medical device manufacturer could include increases in: • Service calls to repair damaged devices • Warranty claims on damaged devices • Product returns of damaged devices TYPICAL APPLICATIONS Below are just a few examples of the many types of medical devices protected by rigid polymer housings and frequently cleaned with harsh disinfectants to fight HAI’s.

These USP-compliant colorants are available in liquid silicone rubber (LSR) and high consistency silicone rubber (HCR) forms and can be customized for specific medical uses. These high-quality silicone dispersions excel in sterilization capabilities while maintaining low toxicity, making them ideal for medical applications. KEY CHARACTERISTICS • Meets USP Class VI standards • Biocompatible • Provides lightfastness, chemical resistance, and heat stability • Available in standard single pigment or custom multi-pigment colors • LSR and HCR options available TARGET APPLICATIONS Stan-Tone HC Plus silicone dispersions are suitable for a variety of healthcare applications including: • Catheters and medical tubing • Medical and surgical equipment • Labware and diagnostic devices • Specialty medical devices and wearables Product Code Pigment Type % Pigment (approx.)
