Potential application of LCL
LCL polymers are mainly applied for absorbable suture (LCL(75:25)) and artificial dura (LCL(50:50)). LCL(75:25) filament is used as monofilament because the filament obtained from LCL(75:25) is tough and flexible.
Applicable examples of the medical device obtained from LCL polymers are shown with color in follows:
