26100-51-6 | Polylactic Acid

Chemical type

• Hydrophilic thermoplastic polymer (biodegradable)

^[1]

• Biodegradable aliphatic polyester
• Lactic acid–based polymer

^[2]

Key properties

• Biodegradable, more hydrophilic than TPU (contact angle ~66.9°).

^[1]

• Biocompatible and biodegradable
• Undergoes hydrolytic degradation under physiological conditions
• Degrades into lactic acid (lactate)
• Slow intrinsic degradation rate
• Can be partially degraded by oxygen plasma treatment to generate lactic oligomers and free lactic acid

^[2]

• Used as a hydrophilic polymeric binder for shaping HKUST-1 powder into composite extrudates/pellets.

^[1]

• Source of sustained lactic acid release
• Encapsulated polymer phase in nanocomposite hydrogels
• Biodegradable component in biomedical devices
• Material for controlled release systems

^[2]

Classification by use

• Polymeric binders for material shaping

^[1]

• Chemicals used in biodegradable polymers
• Chemicals used in drug and metabolite delivery systems
• Chemicals used in biomedical implants and devices
