PP Stay (Polypropylene Stay) is a rigid support material made of polypropylene (PP), manufactured by injection molding.
It is lightweight and highly rigid, making it widely used in medical and rehabilitation applications, including assistive devices, braces, splints, and support structures.
We offer various shapes, including flat “Flat Stay,” central bulged “Bulged Stay,” and curved “Curved Stay,” allowing selection of the most suitable design according to the application.
Key Features
Lightweight and High Rigidity: Polypropylene material ensures lightness while maintaining sufficient strength and stability.
Impact Resistance & Durability: Resistant to cracking or deformation over long-term use, ideal for dynamic areas.
Elasticity & Rebound: Provides appropriate flexibility and resilience for comfortable and stable support.
Workability & Moldability: Suitable for injection and extrusion molding, as well as cutting and drilling for easy customization.
