Bestwood PVC Form Colour Boards includes an advanced master-batching process where a special blend of natural PVC compound is dosed on-line with specific concentrations of pigment enabling the company to produce high quality colours easily and quickly. This means Freefoam can offer many colour products with NO LEAD TIME a significant advantage to many customers. As these are pre-painted and highly finished surface, can be directly used without painting or laminating there by saving cost and time.
