PCU is a kind of PVC granule in which added a physical foam agent, its character is low specific gravity and uniformly foamed PCU products has low density and delicately foamed cell. They are super light and soft after formed, comfortable, low shrinkage.
Low specific gravity
Clear outlook, flat, aesthetical
Good anti-UV yellowing resistance
More improvement than common PVC materials at strength and abrasion resistance
