[0002] PVC coils are generally produced by calendering, which has less fillers and more plasticizers than PVC floor tiles. Generally, PVC plasticized by a four-roll calender is used. After calendering, the surface is flat and smooth. After cooling, the edges are cut and rolled up to form the product. The specifications of the coils vary from country to country. The soft PVC coil floor is soft and elastic, and feels comfortable. Normal cleaning can be done with a dry mop. Difficult-to-remove stains can be removed with a detergent.
