Problems solved by technology

Plenty of plasticizer is required when preparing the in the calender process, however the plasticizer can permeate the PVC product because it is not tightly connected with the PVC product base.
Research on animals indicated that the plasticizer might lead to a reduction in survival rate of the animal, weight loss, reduction of hepatorenal function, decrease of erythrocytes in the blood, possible mutation and cancer.
Researchers also found after examining animals' embryotoxicity that the plasticizer might also cause some serious effects such a...

Abstract

The invention relates to a rigid board plastic flooring comprising a wear layer, a decoration layer, a first connecting layer and a bottom layer which are connected in sequence, and also relates to the production method thereof. The bottom layer of the flooring is prepared using extrusion molding without adding plasticizer. The product is therefore more environmentally friendly. The edge of the click product is not easily damaged during storage and transportation as the bottom layer comprises a plastic hard board and the strength of the click profile is strong.
