One, wood plastic floor WPC

The WPC combines the water resistance and stability of an LVT while being as easy to install as a laminate floor

The addition of cork and EVA pads gives better foot feel and sound insulation compared to the LVT’s latch floor.

The WPC is made of all-green materials, which are more environmentally friendly than laminate flooring.

In short: WPC offers the best of both worlds, LVT and Laminate.

1. Composition

WPC: Wood Plastic Composition=LVT Layer + WPC Core

1.1.1 The LVT layer of WPC and WPC layer are bonded by glue, and the peeling strength is still very good, even better than the bonding strength of LVT color film layer and frosted sheet after hot pressing

1.1.2WPC has better stability than PVC:

The WPC floor was exposed to a high temperature of 80 degrees plus or minus 2 degrees for 6 hours, and then placed at a normal temperature of 23 degrees plus or minus 2 degrees and a humidity of 50% for 24 hours. The following conclusions are drawn:

The length shrinkage is 0.11%

The shrinkage of the width is 0.07%

Warp: 0.25mm

LVT: 0.08-0.15%

Warping: 0.5-1.2mm

2. Advantages of WPC

WPC Engineered Vinyl Flooring — WPC is gold priced, 5.5mm WPC is basically the same price as Vinyl 5.0mm locks and glue-free products, but higher than magic buttons, and much higher than washed glue and common PVC flooring (brushed glue type).

The installation cost of WPC is much lower than that of ordinary brushed PVC floor, lower than that of ordinary PVC locking floor, and the installation cost of non-adhesive PVC floor, magic buckle and washed PVC floor is little different;

WPC waterproof is quite good, wood plastic this layer of waterproof is also very stable, on the contrary, magic buckle, washing glue, ordinary brush glue type PVC floor because it involves glue, waterproof effect is general;

Installation convenience, WPC because of the installation method of Angle-Tap, relatively more convenient, suitable for DIY, of course, need to brush the price of Dry back in this point is the worst.

WPC flooring is definitely good in terms of silence and foot feel, especially with cork or EVA cushion WPC flooring;

WPC is also good in terms of environmental protection, including formaldehyde emission, heavy metals, especially Reach test, 144 all passed.

WPC floor is weak in terms of recycling after use, because WPC (WoodPlastic) cannot be recycled and reused. PVC floor of other products can be recycled and continued to be used as recycling material

The collection can be used as a return material

3. Several issues that need attention in the communication between WPC and customers

(1) Because the LVT layer of WPC is generally only 1.5mm thick, the plate grain should be relatively flat as far as possible. Do not do hand grip and Classic slate (SLATE), and the rate of pressing and sticking defective products will be very high.

(2) The cost of 6.0MM wood-plastic layer is 1.8 dollars higher per square meter than that of 5M wood-plastic layer

WPC+2.0mm EVA Form: Price +USD1.00SQM

WPC+1.5mm Cork: Price +USD1.50SQM

(3) The LVT layer of WPC and WPC layer is bonded by glue, peeling strength is still very good, even better than the bonding strength of LVT color film layer and frosted sheet through hot pressing

(4) For the size of WPC, some may mention that the width of 143mm is needed, which is also the width of our products in the past. However, after testing and mass production experience, the loss of 143mm is relatively large, so it is changed to 146mm, less wear means lower cost.

(5) When preparing the WPC sample, especially when the whole piece of sample is needed, please be sure to assemble it by yourself to see if there is any problem. Some samples in the early stage are defective, so it is OK to make small samples, but the whole piece may have problems such as height difference and inclined head seam when assembled, so please be sure to confirm before sending. Otherwise, the effect will be even worse.

Two, stone plastic floor SPC:

Stone plactic floor SPC(Stone plactic composite), is a new type of environmental protection floor developed based on high-tech, with zero formaldehyde, mildew proof, moisture-proof, fire, insect proof, simple installation and so on. SPC floor is made of extruder combined with T-mold extrusion PVC substrate, with three or four roller calendering machine respectively PVC wear-resistant layer, PVC color film and PVC substrate, one-time heating laminating, embossing products, simple process, laminating by heat to complete, do not need glue. SPC floor materials use environmentally friendly formula, does not contain heavy metals, phthalates, methanol and other harmful substances, in line with EN14372, EN649-2011, IEC62321, GB4085-83 standards. In Europe and the United States developed countries and the Asia-Pacific market is very popular. With its excellent stability and durability, stone plastic flooring not only solves the problem of damp deformation and mildew of solid wood flooring, but also solves the problem of formaldehyde of other decoration materials. It is suitable for indoor home decoration, hotels, hospitals, shopping malls and other public places.

SPC floor shrinkage rate: ≤1‰ (after tempering treatment), ≤2.5‰ (before tempering treatment), (shrinkage test standard: 80℃, 6-hour standard);

SPC floor density: 1.9~2 tons/cubic meter;

SPC floor advantages: SPC floor physical indicators stable and reliable, chemical indicators in line with international and national standards;

SPC floor disadvantages: SPC floor density, heavy weight, high transportation cost;

Production SPC floor and LVT, WPC floor comparison: SPC floor processing, manufacturing process is simple.

Advantages of SPC Environmental protection floor:

SPC floor is a new type of environmental protection composite material products, its advantages are as follows:

(1) waterproof and moisture-proof. It fundamentally solves the problem that wood products are prone to rot, expansion and deformation after absorbing water in wet and multi-water environment. It can be used in the environment where traditional wood products can not be applied.

(2) Insect and termite prevention, effectively eliminate insect harassment, prolong the service life;

(3) Colorful, there are many colors to choose from. Not only has the natural wood feeling and wood texture, but also can customize the color according to their own personality;

(4) Strong plasticity, can be very simple to achieve personalized modeling, fully reflect the personality style;

(5) High environmental protection, no pollution, pollution-free, recyclable. Products do not contain benzene and formaldehyde, for environmental protection products, can be recycled greatly save the use of wood, suitable for sustainable development of the national policy, the benefit of society;

(6) High fire resistance. Can effectively flame retardant, fire grade up to B1, in case of fire self-extinguishing, does not produce any toxic gas;

(7) Good machinability, customizable, planing, sawing, drilling, surface can be painted;

(8) Simple installation, convenient construction, do not need complicated construction technology, save installation time and cost;

(9) no cracking, no expansion, no deformation, no maintenance and maintenance, easy to clean, save later repair and maintenance costs;

(10) Good sound absorption effect, good energy saving, so that indoor energy saving up to more than 30%;

(11) SPC floor relative to LVTWPC floor investment cost less quick effect, less labor, small labor intensity, clean environment.

SPC floor production process:

Procedure: 1. Mixing

According to the ratio of raw materials automatic metering → high speed mixer hot mixing (hot mixing temperature: 125℃, effect

Is a variety of materials mixed evenly, eliminate the water in the material) → into the cold mix (to cool the material,

Prevent caking and discoloration, cold mixing temperature: 55℃. → The material is mixed evenly by cooling;

Step 2: Extrusion

Add the twin-screw extruder, heat extrusion → enter the sheet die head extrusion molding, forming the sheet

After the four-roll calender, the base material is thickened → pasted color film → pasted wear-resistant layer → cooled → cut;

Step 3: UV tempering

Surface UV→ tempering (tempering hot water temperature: 80~120℃; Cold water temperature: 10℃)

Step 4: Grooving + packing

Slitting, slotting, trimming, chamfering, testing, packaging

SPC floor formula (formula cost 2200 yuan/ton)

The above is the basic formula of SPC floor, the formula of different manufacturers is slightly different
