Bio-Based Content of PA56 Products Difficult to Verify
Problem Phenomenon
The bio-based content of PA56 products is difficult to verify, and carbon footprint accounting lacks standard methods
Cause Analysis
The proportion of lysine source in PA56 is difficult to accurately determine
The testing standards for bio-based carbon content are not unified
The traceability of raw material sources in the supply chain is difficult
PA56 and PA6 have similar properties and are difficult to distinguish
Customers have insufficient trust in bio-based claims
Solution
Use C14 carbon isotope testing to verify the bio-based content
Test with reference to the ISO 16620 standard
Establish a supply chain traceability system
Provide bio-based content declarations and third-party test reports
Strengthen communication with customers on bio-based advantages
Key Takeaway
PA56 bio-based verification requires standard testing and traceability
