Hook and Loop Sanding Disc Manufacturer
Rex manufactures hook and loop sanding discs in three series: film-backed, paper-backed and cloth-backed. They come in 4 abrasives (aluminum oxide, zirconia, silicon carbide and ceramic), grits 24–600 and four shapes: round discs, delta, mouse and rectangles. Hole patterns and sizes can both be customized.

Three Backing Series
Choose the series by backing first. The backing sets how the disc feels and what it is used for.
| Series | Backing | Bond | Features | Main Uses |
|---|---|---|---|---|
| Film-backed | Flexible PET film | Resin | Flat surface, uniform scratch pattern, semi-open coat resists clogging | Automotive paint prep, metal sanding, wood |
| Paper-backed | C, D or E weight paper | Full-resin | General purpose, cost-effective, choice of paper weight | Wood, metal, automotive prep |
| Cloth-backed | Cloth | Confirmed when quoting | Tear-resistant, suits curves and edges | Metal sanding, heavy-duty work |
Heavier paper gives a stiffer, more durable backing. Lighter paper is softer and conforms better to the workpiece.
How to Choose Among the 4 Abrasives
Aluminum oxide
the general-purpose choice for wood, metal and automotive prep
Zirconia
metal removal and deburring, with a fast cut
Silicon carbide
hard, brittle materials such as stone and glass (paper-backed series)
Ceramic
professional metal sanding and demanding surface finishing
Shapes and Sizes
Abrasive, grit, diameter, shape, hole pattern, backing and attachment method can all be customized to your requirements.
| Shape | Size | Compatible Tools |
|---|---|---|
| Round discs | 50 / 75 / 100 / 115 / 125 / 150 / 180 / 225 mm diameter | Random orbital sanders, pneumatic sanders |
| Delta | 93 × 93 × 93 mm | Delta sanders, for corners |
| Mouse | 140 × 100 mm | Mouse sanders |
| Rectangles | 93 × 230 mm, 115 × 280 mm | Orbital sheet sanders, hand sanding blocks |
Hole Patterns
The hole pattern must line up with the dust extraction holes on your sander’s backing pad. If they don’t match, dust extraction suffers.
- Standard hole patterns: no holes, 5-hole, 6-hole, 8-hole, 8+1-hole, 15-hole, multi-hole
- Custom hole patterns: die cut to match your backing pad or sample
When you request a quote, state the diameter and hole pattern, or send a sample.
Grit
Grits 24–600, used in stages:
- 24–60: old paint removal, coarse sanding
- 80–150: leveling, removing scratches
- 180–320: sanding body filler and primer
- 400–600: fine sanding before painting
The Loop Backing Determines How Long a Hook and Loop Disc Lasts
Hook and loop discs change quickly because the loop backing grips the hook face of the backing pad. A poorly made loop backing leads to discs falling off, weak grip and adhesive failure at high temperatures.
- Usage tip: replace the backing pad once its hook face wears, or even new discs won’t hold
- Laminating: Rex controls the bond between the abrasive layer and the loop backing during laminating to prevent delamination
- Die cutting: controls the outer diameter and hole positions so the holes align with the dust extraction holes on the backing pad

Frequently Asked Questions
We work systematically to integrate corporate responsibility in our core business and make our expertise available for the benefit of the societies where we operate.
Film-backed or paper-backed: which should I choose?
If you need a high-quality finish with a uniform scratch pattern (for example on automotive paint), choose film-backed. For general sanding where price matters most, choose paper-backed.
Can you match our backing pad's hole pattern?
Yes. Send a backing pad or a hole layout drawing, and Rex will die cut to the drawing.
What is the most common hole pattern?
It varies by market and depends on the leading sander brands there. The safest approach is to send a backing pad or a used disc, and Rex will die cut to match the actual part.
Can you make mixed-grit kits?
Yes. Grit combination, discs per kit and packaging can all be customized.
Do you offer an anti-clog coating?
Sanding paint and body filler calls for an anti-clog (stearate) coating. Mention it in your RFQ; it is confirmed by Rex when quoting.
