This document applies to foam mats made from woven or non-woven fabrics as substrates, using polyvinyl chloride paste resin with plasticizers and other additives as coating material. These mats are manufactured through processes such as coating, shaping, plasticizing, foaming, and post-processing. Non-foamed products may also be manufactured using this document.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
