Product Description

SPC Floor Raw Materials Auxiliary Agent Overview

The main raw materials of SPC floor are PVC and heavy calcium carbonate powder,and a series of processing additives need to be added to adjust the characteristics,so as to make SPC floor core.

The following are the details for a single batch of raw materials,just for reference,the actual will be according to the site condition.

SPC Floor  Raw Material Auxiliary Agent

Ca-Zn Stabilizer

1. Ca-Zn Stabilizer

The initial coloring is good, the thermal stability time is long, and the production is stable.

The plasticizing time is short, the dosage of the regulator can be reduced, and the cost can be reduced.

Stable processing performance, low temperature plasticization, good molding and processing, good mechanical properties of products, fast extrusion speed and high output.

Passed the SGS test and met the requirements of the EU ROHS environmental protection standard. It is an ideal substitute for the national lead ban.

Plastic modifier

2. Plasticizing modifier

This type of product has the characteristics of multi-function, wide processing range, high cost performance, convenient use and stable product. Widely used in various PVC products.

For SPC floor to increase the strength of the product.

For PVC foam wallboard : increase the hardness and strength of the product .

For WPC floor : increase the impact resistance and strength of the product. 

For PVC foam board : increase the hardness of the core layer.

Impact Modifier

3. Impact Modifier

This type of product is a high molecular polymer with a network interpenetrating structure. Its main function is to improve the low-temperature impact strength of PVC products and the toughness of the product, and to promote the plasticization of PVC materials. 

Has the following characteristics:

Increase the excellent low temperature impact strength of PVC products, improve toughness and hardness, increase the excellent welding fillet strength, and increase the better surface gloss of PVC products;

In WPC application, it can improve the nailing force of wood-plastic products, excellent weather resistance.

PE wax

4. PE Wax

PE wax is not only a lubricant, but also has a dispersing effect。

But the addition amount will affect the balance of internal and external lubrication , the deterioration of melt strength, increase the shrinkage rate of the product , reduce the peeling force, and the product becomes brittle.

 SPC Floor Advantages

spc floor advantages

  • ECO-friendly

    SPC floor uses calcium powder and PVC as the main raw materials, non-toxic and renewable resources.

  • Fire Retardant

    Even if something burns on the SPC floor ,such as cigarette or a lighter,it will not be affected.

  • Wear-resistant

    There is a wear-resistant layer on the surface, its wear-resistant revolution can reach 8000-16000 . Ordinary laminate flooring are generally only 1200-9000 revolutions.

  • Waterproof and Damp-proof

    SPC floor produced by the SPC floor machine solves the problem of rotting, swelling and deformation of wood products due to moisture absorption and water absorption in the environment, suitable for any place.

  • Easy Maintenance

    Maintenance-free, easy to clean, saving later maintenance costs.

  • Easy to clean

    Wear-resistant layer has special skid resistance,feet feel more astringent when floor is wet.

What is the whole SPC Floor Production Line ?

spc flooring production line

  1. Mixing machine

    Mixer unit combines hot mixer with cold mixer process, and the hot mixer material automatically enters the cold mixer to cool it, eliminate the residual gas, and prevent caking.

  2. SPC extrusion line

    The SPC floor extruder converts the mixed raw materials into the SPC core layer by the double screw and T-die, and laminating the wear-resistant layer and decor film on the core layer with emboss roller, and finally form the large board of the SPC floor.

  3. UV coating line

    UV coating line is designed for coating UV varnish on SPC floor,WPC floor,WPC floor,LVT floor,PVC marble sheet,PVC cabinet board etc,which can give the feathers of anti scratch,bacteria roof,stain resistance.Each Coating roller controlled by individual motor to make exact coating quantity and effect.

  4. Cutting and double end tenoner line

    Usually, the multi-rip saw is connected with the double end tenoner(DET) line. The multi-rip saw is used to cut the SPC large board into several small pieces, and then turn over the board and enter the DET line to do the click profile on the long and short sides. It can be matched with automatic feeding system to reduce labor.

  5. V groove painting line (optional)

    Cut some of the upper edge of the SPC floor at 30/45°, and then paint it. After paving, the seam will show a V-shaped notch. The edge color is rich and layered, and it is more beautiful.

  6. IXPE / EVA laminating line (optional)

    Bond the underlayment materials on the backside of the SPC flooring to improve the ability of sound insulation.

  7. Auto packing and Stacking (optional)

    It can automatically fold the carton, put a certain number SPC flooring into the carton and pack it automatically, and finally stack it with a conveyor or robot.
