BioMed Elastic 50A is a transparent, biocompatible material designed for applications requiring softness, flexibility, and medical-grade performance. With a Shore hardness of 50A - comparable to human tissue - it is particularly suited for creating patient-specific medical devices, surgical models, and prototypes where comfort and safety are essential.
Manufactured in an ISO 13485–certified facility and compliant with USP Class VI standards, BioMed Elastic 50A is validated for long-term skin contact (>30 days) and short-term mucosal contact (<24 hours). The material delivers a unique balance of high elongation at break (150%) and tensile strength (~2.3 MPa), allowing it to bend, stretch, and recover under repeated use.
Key Benefits
-
Silicone-like flexibility – With a Shore hardness of 50A, parts stretch and bend repeatedly without tearing.
-
Biocompatibility certified – Meets ISO 10993 and USP Class VI standards, suitable for applications requiring skin or mucosal contact.
-
Durable and resilient – Withstands repeated cycles of bending, compression, and elongation.
-
Precision in soft materials – Enables accurate production of complex geometries while maintaining softness and comfort.
Applications
-
Medical device prototypes – Soft-touch components, seals, and enclosures for device testing and validation.
-
Wearable devices – Comfortable, skin-contact parts such as straps, cushions, and custom-fit prototypes.
-
Patient-specific models – Anatomical parts and simulation tools for surgical planning and education.
-
Research tools – Flexible flow channels, tubing, and test components for biomedical and life sciences.
