High processing temperatures cause polymer discoloration and loss of mechanical integrity. Preventing these degradation modes ensures material durability and aesthetic consistency in demanding environments.

Inadequate bonding between thermoplastic polyesters and metallic substrates leads to structural delamination. Robust interfacial integrity is required for durable plastic-metal hybrid components.

Standard biodegradable polymers often require industrial composting conditions to break down. Enhancing home compostability addresses the failure of materials to degrade in low-temperature, non-industrial environments.
