Wood–plastic composite (WPC) identifies wood combined with polymer. The terms overlap: some standards use WPC for a wider group of cellulose-based thermoplastic composites. Always check the definition in the document you are using.","takeaways":"Check the definition used by the standard or supplier.\nIdentify the fibre and matrix separately.\nNeither acronym is a performance certification.","sections":[{"id":"definitions","heading":"What do NFC and WPC mean?","text":"In this reference, NFC is the broad plant-fibre composite family, and WPC is the wood-containing polymer group. Industry usage is not completely uniform. The EN 15534 series covers cellulose-based materials combined with thermoplastics and uses WPC as an abbreviated label within that scope.","references":[1],"url":"https://woodplasticcomposite.net/guides/nfc-vs-wpc/#definitions"},{"id":"matrix-scope","heading":"Does WPC always mean a thermoplastic?","text":"Wood–plastic composite can be used broadly for wood combined with thermoset or thermoplastic polymers.
