Features & Benefits
High Flow for Complex Designs
With a melt flow index of 22 ml/10 min, PC-122P fills intricate molds effortlessly, reducing cycle times and enabling production of thin-walled or detailed medical components like IV connectors or surgical housings.
Medical-Grade Durability
Boasting 63 MPa tensile strength and 60 KJ/m² impact resistance, this resin withstands repeated sterilization (autoclaving) and mechanical stress, ensuring long-term performance in devices like surgical instruments or diagnostic tools.
Heat & Sterilization Resistance
A Vicat softening point of 150℃ and 143℃ heat deflection temperature (annealed) allow PC-122P to endure high-temperature sterilization without warping, critical for reusable medical equipment.
Use & Applications
Medical application:
- Surgical Instrument Housings
- IV Components
- Medical Imaging Devices
- Drug Delivery Systems
- Dental Equipment
