BSP is the the brand name of BINIC Abrasive.

It also covers our products for Cutting and Grinding wheel, diamond wheel, diamond cup wheels, diamond core bits, wire wheel and brushes. We are also looking for flap disc distributor and dealers. We are going to set up a warehouse in Dubai to cover a market in middle east. Also the USA warehouse in Texas is in our plan on 2020.
Before you ordering the flap discs, you must understand what is the difference between flap wheel and grind wheels.
In general, the flap disc is coated abrasive branch, and grinding wheel is still resin bonded abrasive. The detailed differences are as following:
- Grinding wheel: It only provides grinding function to metal and stone, sometime can cut a little bit without changing the wheels.
- Flap disk: it provides not only grinding, but also polishing/finishing and blending. It is faster for stock removing, and most important is much less heat in working to avoid burning.
There is only black label which will be “burning” together with backing for flap disc.
There is no minimum quantity request if it is BSP logo (BINIC ABRSAIVE brand name). we request for each size and grit 3000pcs for other private label.
Attention: There is also an alternative if customer can not reach the minimum quantity. They can pay for the printing cost as well as label stock (normally for stock like 3000pcs labels and together with printing cost is not over 200USD). BINIC will help to stock those labels and consume them in the next orders.
There is 2 shape of flap wheel Flap Discs
one is T27 which is depressed center and flat surface, the other one is T2 which is also depressed center but conical surface. The difference in application is as following:
- T27 Flap disc : Is is very good for flat surface. Most people use T27 type of flap disc to polishing/finishing and blending. 60% people choose T27 for their flap wheels.
- T29 flap disk: It can provides very aggressive performance in stock removing. As it has a conical flap, people can also use it in groove and edge working.
In general the flap disc has 2 parts.One is backing and the other one is flaps.
In production, we purchase the flaps from some other coated abrasive in rolls, and slice it in the pieces. Then we glue the flaps on the backing. So you can see the backing is to support and hold the backings.
There are 2 major backings sell in the market so far.
- Fibreglass backing plate: It is very light, no smearing inside and can absorb vibration in using. Normally we have 8 layers fibre glass inside to provide a very good strength. Some customer may ask 9 or 10 layers for better strength. It can be consumed during work.
- Plastic backing: It is new trend and become more and more popular. One reason is it is trimmable, that means people can use more flaps during works. Another reason is the cost of fibre backing increase a lot in recent years as it is a high polluted industry.
So flaps is the most important parts of flaps disc, it directly affects speed and life.
Also we must choose the right quality flaps when we working on different material.
The detailed information are as the following:
Number of flaps: The flaps numbers in flap disc can be varied.
- The standard flaps for 115mm and 125mm are 72pcs, and 180mm are 108pcs. It can provide very high speed and fast stock removing.
- The increased flaps for 115mm and 125mm are 80pcs, and 180mm are 120pcs. It is very good for uneven surface and also good for fine grit polishing.
Flap quality: It is most important part of flap disc, details are as following:
- Aluminium oxide: This is a very basic material when we start to polishing metal. It is cheap and also good speed. Very good for mild steel, plastic, wood. It is a general working type.
- Zirconia Alumina: It is a higher grade abrasive, very good for carbon steel, mild steel even the stainless steel. It can achieve much better life and speed. (it also called Zirconia Corundum Zirconium Corundum)
- Silicon carbide:This is a very hard material, very good for Non metal material such as stone, concrete and plastic.
- Ceramic Alumina: This is top quality material so far. Best speed and life. Also very expensive. It is good for hard alloy and stainless steel.
Grit size: It means the size of the abrasive you must choose for your application. The coarse abrasive normally work for rough grinding or remove the big stock, the fine abrasive normally work for finishing and blending. Please check the following chart for the
- 24-36：heavy stock removal, edge chamfering, weld blending
- 36-40：edge chamfering, weld blending,
- 40-50：weld blending, deburring
- 50-60：deburring, rust removal
- 60-80：rust removal, finish and polish

As an abrasive flap discs suppliers, we have 2 quality of our Aluminium Oxide flap disc
- Standard line: It is good for small job like mild steel, wood or plastic. has cheap fibre backing 7-9 layers. We make test with T29 115mm with girt size 40 to grind a carbon steel plate. In 20 minutes it grinds off 198g material and self lost 13.5g. The grinding ratio is : 1:14. Very good speed but life is normal.
- Professional Line: We make the same test, in 20 minutes the flap wheel grind off 206g and self lost 9g. The grinding ratio is 1:22. Better Speed and much better in life.
We have 3 quality to our Zirconia Alumina
- ECO line: As we are using very normal domestic Zirconia Alumina paper, the eco line can use for mild steel and other Non Metal material. A little bit on the stainless steel.
- Standard Line: We are using premium domestic quality Zirconia paper. It is very good for different metal including stainless steel, carbon steel and some other alloy. So we use T29 115 with 40 grit size to grinding stainless steel. In 20 minutes it ground off 80g material and consume itself around 4g. The ratio is around 1:20.
- Premium line: We are using paper from VSM or 3M. Quite expensive but it can grind any type of steel. The same testing on the stainless steel, in 20 mins it ground off 120g material and consume itself around 5g. The ratio is around 1:24.
We are supplying now the ceramic flap disc, it is quite expensive as we also import this paper from VSM, obviously, it is the best flap disc we can have.
