Hard PVC plasticizer-free, and therefore easy to shape, good physical properties pvc pipe standards, so it has great development and application value. PVC material production process, is bound to add some additives, such as stabilizers, plasticizers, etc., if used in all environmental additives plastic pvc pipe, PVC pipe that is also non-toxic tasteless green products.
