Comparison between WPC and SPC flooring
Wood Plastic Flooring WPC combines the waterproofness and stability of LVT, and is also as easy to install as laminate flooring With the addition of cork and EVA pads, the foot feel and sound insulation effect will be better than LVT lock flooring. WPC uses all environmentally friendly materials, which is more environmentally friendly than laminate flooring.
In short: WPC is between LVT and Laminate, and has the advantages of both.
1. Composition WPC: Wood Plastic Composition=LVT Layer + WPC Core
1.1.1 The LVT layer and WPC layer of WPC are bonded by glue, and the peeling strength is still very good, even better than the bonding strength of the color film layer and frosted sheet of LVT after hot pressing
1.1.2 The stability of WPC is better than PVC: WPC floor is placed at a high temperature of 80 degrees plus or minus 2 degrees for 6 hours, and then placed at a normal temperature of 23 plus or minus 2 degrees and 50% humidity for 24 hours for observation.
The following conclusions were drawn: Shrinkage in length is 0.11% Shrinkage in width is 0.07% Warp: 0.25mm LVT: 0.08-0.15% Warp: 0.5-1.2mm 2. Advantages of WPC WPC Engineered Vinyl Flooring——The price of WPC is gold-level.
The price of 5.5mm WPC is basically the same price level as Vinyl's 5.0mm lock and glue-free products, but higher than magic buckle, and much higher than water-washing glue and ordinary PVC floor (brush glue type); The installation cost of WPC is much lower than ordinary brush glue PVC floor, lower than ordinary PVC lock floor, and glue-free PVC floor.
The installation cost of magic buckle and water-washing glue PVC floor is not much different; The waterproofness of WPC is quite good, and the waterproofness of the wood-plastic layer is also very stable. On the contrary, magic buckle, water-washing glue, and ordinary brush glue PVC floor involve glue, so the waterproof effect is average; In terms of installation convenience, WPC is relatively convenient because it is installed by Angle-Tap, which is suitable for DIY. Of course, Dry back, which needs to be brushed separately, is the worst in this regard.
WPC flooring is definitely good in terms of quietness and foot feel, especially WPC flooring with cork or EVA pads; WPC is also very good in terms of environmental protection, including formaldehyde emission, heavy metals, and especially Reach test, all 144 items passed.
WPC flooring is weak in terms of recyclability after use, because WPC (Wood Plastic Composite) cannot be recycled and reused, while PVC flooring of other products can be recycled and used as recycled materials
3. Several issues that need to be paid attention to in communication between WPC and customers
(1) Because the LVT layer of WPC is generally only 1.5mm thick, try to choose a relatively flat board pattern, and do not use hand-scratched and Classic slate (slate pattern), otherwise the defective rate of pressing will be very high.
(2) The cost of 6.0mm WPC layer is 1.8 USD per square meter higher than that of 5M WPC layer WPC+2.0mm EVA Form: Price + USD1.00SQM WPC+1.5mm Cork: Price + USD1.50SQM (3) The LVT layer and WPC layer of WPC are bonded by glue, and the peel strength is still very good, even better than the bonding strength of the LVT color film layer and frosted sheet after hot pressing
(4) Regarding the size of WPC, some may mention that a width of 143mm is required. Our products used to have this width, but after testing and mass production experience, the loss of 143mm will be greater, so it is uniformly changed to 146mm. Less wear means lower cost.
(5). When preparing WPC samples, especially when a whole sample is needed, please be sure to assemble it yourself to see if there are any problems.
Some samples were defective in the early stage. It is okay to make a small sample, but the whole piece may have problems such as height difference and bevel joints when assembled, so please confirm it before sending it. Otherwise, the effect will be even worse after sending it.
2. Stone plastic floor
SPC: Stone plastic floor SPC (Stone plactic composite) is a new type of environmentally friendly floor developed based on high technology. It has the characteristics of zero formaldehyde, mildew resistance, moisture resistance, fire resistance, insect resistance, and simple installation.
SPC floor is a product that is made of an extruder combined with a T-die to extrude the PVC base material, and a three-roll or four-roll calender is used to heat and bond the PVC wear-resistant layer, PVC color film and PVC base material at one time.
The process is simple, and the bonding is completed by heat, and no glue is required. SPC flooring materials use an environmentally friendly formula, do not contain heavy metals, phthalates, methanol and other harmful substances, and comply with EN14372, EN649-2011, IEC62321, GB4085-83 standards. They are popular in developed countries in Europe and America and the Asia-Pacific market.
With its excellent stability and durability, SPC flooring not only solves the problem of solid wood flooring being damp, deformed and rotten, but also solves the formaldehyde problem of other decoration materials.
It has many colors and patterns to choose from, suitable for indoor home decoration, hotels, hospitals, shopping malls and other public places. SPC floor shrinkage rate: ≤1‰ (after tempering), ≤2.5‰ (before tempering), (shrinkage test standard: 80℃, 6 hours standard); SPC floor density: 1.9~2 tons/cubic meter; SPC floor advantages: SPC floor physical indicators are stable and reliable, and chemical indicators meet international and national standards; SPC floor disadvantages: SPC floor has high density, heavy weight, and high transportation cost; Comparison of SPC floor production with LVT and WPC floor: SPC floor processing and manufacturing process are simple.
Advantages of SPC environmentally friendly floor: SPC floor is a new type of environmentally friendly composite material product, and 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 and moisture in humid and watery environments and can be used in environments where traditional wood products cannot be used.
(2) Insect and termite-proof, effectively preventing insect harassment and extending service life.
(3) Colorful, with many colors to choose from. It has both natural wood texture and wood texture, and can be customized to the desired color according to one's own personality.
(4) It has strong plasticity and can easily achieve personalized shapes, fully reflecting one's personal style.
(5) It is highly environmentally friendly, pollution-free, harmless, and recyclable. The product does not contain benzene and formaldehyde, is an environmentally friendly product, and can be recycled, which greatly saves the use of wood, is in line with the national policy of sustainable development, and benefits society.
(6) It has high fire resistance. It is flame retardant, with a fireproof rating of B1. It will extinguish itself when exposed to fire and will not produce any toxic gases.
(7) It has good processability and can be customized, planed, sawed, drilled, and painted.
(8) It is easy to install and convenient to construct. It does not require complicated construction techniques, saving installation time and costs.
(9) It does not crack, expand, or deform. It does not require maintenance and care. It is easy to clean and saves costs for later repairs and maintenance.
(10) It has good sound absorption and energy-saving properties, making indoor energy saving up to 30% or more.
(11) Compared with LVTWPC floors, SPC floors have low investment costs, quick results, less labor, low labor intensity, and a clean environment. SPC floor production process: Process: 1. Mixing Automatically measure according to the raw material ratio → hot mixing in high-speed mixer (hot mixing temperature: 125℃, the function is to mix various materials evenly and remove moisture from the materials) → enter cold mixing (cool the materials, prevent caking and discoloration, cold mixing temperature: 55℃.) → cool and mix the materials evenly.
Process 2: Extrusion Add to the twin-screw extruder for heating and extrusion → enter the sheet die for extrusion molding, and the formed sheet passes through a four-roll calender, the base material is fixed in thickness → color film is applied → wear-resistant layer is applied → cooling → cutting.
Process 3: UV tempering Surface UV → tempering (tempering hot water temperature: 80~120℃; cold water temperature: 10℃)
Process 4: slitting and slotting + packaging Slitting → slotting, trimming, chamfering → inspection → packaging
