1.1 PVC (poly-vinyl chloride), name: plastic floor, sometimes also called elastic floor. Specifically, using polyvinyl chloride and its copolymer resin as the main raw materials, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials, on a continuous sheet-like substrate, after the coating process or after calendering, extrusion or extrusion Crafted.
1.2 LVT / LVP: luxury vinyl tile / luxury vinyl plank, high-grade vinyl floor tile / high-grade vinyl floor, the main components are PVC resin, stone powder, and additives. Generally, a glass fiber layer will be added in the middle to increase the strength and stability. So it is usually made of multiple layers. The density is generally 1.8 ~ 2g / cm³.
1.3 WPC: wood plastic composite WPC flooring (in fact, because wood powder is added, it is difficult to process after processing and raw material recovery, so there is no wood powder in the WPC floor substrate formula at present) Now the base material is mainly made of foamed and extruded stone powder, PVC resin, and additives. Then press a layer of LVT on the surface of the substrate. The density is about 0.8 ~ 1g / cm³.
1.4 SPC: stone plastic composite, stone plastic floor. European and American countries call this kind of floor RVP (rigid vinyl plank), rigid plastic floor. The main components are stone powder, PVC resin, and additives. Compared with LVT stone powder, it accounts for a relatively large proportion of finished products. The density is generally 1.9 ~ 2.1g / cm³. There are two production methods: extrusion molding and pressure molding.
1.5 ABA: ABA floor, the floor base material is mainly composed of upper, middle and lower layers. At present, there are two kinds of production: one is produced by co-extrusion through an extruder, surface SPC, middle layer WPC, bottom SPC, or surface SPC, middle layer SPC, bottom SPC, surface layer, bottom layer and middle layer SPC The formula and density are different. One is lamination by hot pressing machine, surface LVT, middle layer SPC, bottom layer LVT, or surface layer LVT, middle layer WPC, bottom layer LVT.
1.6 Heterogeneous poly (vinyl chloride) floor: Heterogeneous poly (vinyl chloride) floor: A floor made of different layers. The above LVT, WPC, SPC and ABA all belong to this range.
1.7 Homogeneous poly (vinyl chloride) floor: homogenous and translucent polyvinyl chloride floor. The pattern material from the surface to the bottom is the same.
2. Classification of plastic flooring
2.1 From the perspective of product form, it is divided into coiled floor and sheet floor.
2.2 From the point of view of product structure technology, it is divided into homogeneous through heart, LVT, WPC, SPC, and ABA structure floor.
2.3 From the perspective of assembly method, it is divided into: dry back / glue down, click, and loose lay.
A. Dry back needs to be assisted with glue, also known as glue down. Generally thin.
B. Click the buckle to install, use the buckle to connect the small piece of floor. Suspended on the ground. Available from 3.2mm to 8mm.
C. loose lay can be paved directly (the loose lay bottom layer has a layer of soft skin, which is not easy to push on a flat surface.)
