More Questions
What is the hardness?
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond
How about your delivery time?

What are the three basic raw materials used in the manufacture of coated abrasives?
Grain – a synthetic or natural abrasive; Bond – an adhesive that permanently bonds the backing to the abrasive; Backing – a backing that the abrasive is bonded to
What are the different coated abrasive grain types and their characteristics?
Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include
Type of glue required:
This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the
Can you customized quality, size, package according to customer?
Yes, of course. The OEM is available. We will do the creation in your requirement and make ur image come true.
Is brown aluminum oxide a possible substitute for high crystalline silica containing abrasive materials?
Yes. According to NIOSH, Brown Aluminum Oxide could be a viable substitute for consumers looking for safer alternative materials to high crystalline silica content abrasive products.
What are the different types of abrasive bonds used in coated abrasives?
Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials. Phenolic Resin – This system uses
What is your sample policy?
We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.
Can you provide free samples?
Yes.FREE SAMPLES 5kg can be provided for your evalution.
What is the d50 value?
The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.
What is the specific surface?
The specific surface means the outer surface of a substance including all accessible pores in relation to the mass. It is determined using the Brunauer-Emmett-Teller (BET) method.
What is silicon carbide?
Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly
What is the refractive index of white fused alumina compared with that of glass?
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
Where’s your main market?
Our main market include Europe,America,Oceania,Asia.,etc.
Form and shape of the abrasive:
This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the
What is porosity?
Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower
Amount of abrasive applied:
This decision is made by knowing the type of material you will be working with. Open Coat – Here, the abrasive granules cover from 50% – 70% of the backing and are set at pre-determined spacing to reduce
