Considering its interlocking system, PP is more brittle than PVC. In theory, manufacture should use same PP material for its wear paper, decor paper and balance paper during production. However, actually many manufactures prefer to use PVC resin as its paper raw material in order to reduce producing cost. Sometimes they will add some other additional agents to ensure the whole structure more stable.
PP flooring vs. PVC flooring
1) Heat Resistance:PVC flooring will slowly melt and deform when exposed to sunlight for too long time. PP flooring has better heat resistance up to about 300℉.
2) Degradability:PVC can not be totally degraded in the nature because of its chlorine. PP can be degraded without any pollution.
3) Impact Resistance:PP flooring is more fragile than PVC, even will be damaged by dropping a hammer on it. PVC has better impact resistance.
