The key to SPC floor wear resistance-Transparent wear layer

What is SPC floor?

（1）In terms of species

SPC floor, Stone Plastic Composite, is a hard plastic floor, which can also be bent, but compared with LVT floor, the curvature is much less. Its common name is stone crystal floor, which is called stone-plastic floor or plastic stone floor in Hong Kong and Taiwan. Except for Europe and the United States, Southeast Asia is one of the regions where SPC floor is used most, because it not only has high appearance value, but also has excellent waterproof and moisture-proof performance , lower cost than laying floor tiles, and saves laying time.

（2）In terms of material

The main material of SPC is 25% polyvinyl chloride + 75% calcium carbonate powder, which is a kind of hard sheet flooring.

（3）In terms of usage

SPC is suitable for home, hotel, restaurant, school, hospital and other places.

（4）In terms of thickness

SPC floor, generally 4-7mm

（5）Click Lock System

A click system is used at the base that will allow the product to fit together like a jigsaw puzzle.

（6）Load Bearing Layer

This layer, known as the base layer, gives the product strength and durability to withstand the weight placed on it.

What is a transparent wear layer?

Wear layer essential for luxury vinyl planks and tiles

If you're choosing luxury vinyl planks or tiles for your home, you should know that each product comes with a hard wearing layer. This layer protects against wear such as scratches, scuffs and stains, but what is it?

Simply put, the wear layer is made of polyurethane and added on top of the image layer but just below the top final finish.This wear layer is only available in luxury vinyl, and you'll find it available in a variety of thickness.

How to see whether the PVC floor is wear-resistant

When some users ask about the service life and wear resistance of the PVC floor, they take out a sharp tool such as a knife or a key, and scratch the surface of the PVC floor. If there are scratches, they feel that it is not wear-resistant.

This detection method is actually incorrect. The international standard for testing the abrasion resistance of PVC flooring is not simply scratching the surface with a sharp tool. It is to use a flat-bottomed circular grinding disc to polish the test floor under the pressure of 1Kg. Each revolution of the test and grinding is a circle, and it is continuously polished. From the wear-resistant layer of the floor to the printing layer, there is no number of revolutions to damage the printing layer.

The PVC floor industry first emerged from Europe, and the wear-resistant grade is a standard established by Europe, which is divided into T grade, P grade, M grade, and F grade. In order from high to low, T grade is the higher level of wear resistance, and F grade is the lower level.

EN 660-1: Separated by wear thickness.

EN 660-2: Separated by wear volume.

EN 660-2 Resilient floor coverings - Determination of wear resistance

Part 2: Frick-Taber test Resilient floor coverings. Determination of abrasion resistance.

The test results of EN 660-2 are more accurate, so the test method of EN 660-2 is adopted for the wear resistance grade of PVC floor:

(1) The weighing sample is accurate to ±0.1mg.

(2) Grind one sample for 5000 revolutions, stop after every 1000 revolutions and weigh the weight, and test the other two samples. If the first sample is worn through during 5000 revolutions, eliminate and test the remaining 2 samples for 200 revolutions/cycle until after 2000 revolutions or when the samples are worn through.

(3) Calculate the average quality loss. Fm, expressed in mg/100 revolutions Fm=Ftot/n*100 Calculate the quality loss value of each sample at 100 revolutions: Fv=Fm/ρ The loss value Fv is (mm3)/100 revolutions

The higher the number of grinding revolutions, the better the wear resistance of the floor. In the wear-resistant rotation test, the general rotation speed of composite floor is 1500-2000 rotations, the rotation number of solid wood floor is 1500-2500 rotations, and the rotation number of ordinary floor (belonging to the multi-layer composite stone-plastic floor in PVC floor) is 5000-60000 rotations Turn (depending on the thickness of the wear-resistant layer of the product).

The test tells us: it is wrong to simply scratch with a sharp tool to test the wear resistance of PVC flooring.

T grade: Fv≤2.0

P grade: 2.0≤Fv≤4.0

Class M: 4.0≤Fv≤7.5

Class F: 7.6≤Fv≤15.0

You can choose a general-purpose product with a wear-resistant revolution of about 5000 revolutions;

In places like schools, hospitals, office buildings, factories, etc., it is necessary to choose durable products with a wear-resistant revolution of more than 10,000 revolutions. 

When we buy PVC flooring, it doesn't mean that the thicker it is, the more appropriate it is. We should choose products with appropriate thickness according to the occasion we use. Only in this way will it be worth the money and buy a satisfactory floor.
