Identity and form lock
1. Write the polymer identity
State nylon 6, nylon 66 or another named grade and the CAS number when known. Similar webbing names can hide different resin families, stabilizer packages or recycled content.
2. Freeze form and melt flow
Record chip, pellet, yarn, woven webbing or rope form. If the converter cares about viscosity or melt flow, write the requested range and leave the supplier to confirm the method.
