Key Material Performance Advantages
1. Excellent Biocompatibility
All BD LSR grades pass ISO 10993 biological safety test, non-toxic, non-irritating to human tissue, safe for long-term skin and body contact medical devices.
2. Adjustable Hardness Range
Shore A hardness covers 20 to 70, from ultra-soft flexible balloon material to rigid hard catheter accessories, matching all medical design demands.
3. Superior Mechanical Properties
High tensile strength, ultra-high elongation rate, strong tear resistance. Products will not crack or break under repeated bending, squeezing and stretching in clinical use.
4. Stable Physical Shrinkage
Controllable linear shrinkage between 2.0%~2.1%, ensures high dimensional precision for tiny medical molded parts.
5. Crystal Clear Transparency
Full transparent raw material, allows visual observation of liquid flow inside catheters and balloons, convenient for medical staff operation.
6. Stable Curing Process
1:1 equal volume mixing ratio, simple processing; fast curing at 130°C, high production efficiency for mass medical product manufacturing.
