PVC floor tile is constructed with many layers of materials. Typically, from top to bottom, there is a transparent PVC film with various thickness (abrasion resistance), a printing film (aesthetic purpose), a white PVC film (background for printing film), and a composite PVC body (form a rigid shape).

The composite body is compounded with several components: recycled PVC, virgin PVC, plasticizer, calcium carbonate, stearic acid derivatives, PE wax, stabilizer, pigment, and etc. Since those recycled PVCs are received from various resources, the total content of plasticizer in the composite is always uncertain.

For self stick PVC floor tile, hot melt pressure sensitive adhesive (HMPSA) is coated on the top of the composite body piece by piece with a top feed roll coater. The coating speed is up to 160 pieces per minute for 1 square foot tiles. The adhesive surface is automatically covered with…Read Article>>
