Flexi-Plast 30 Micron Self-Adhesive Aluminum Oxide Finishing Sheet – 8.5" x 11"

Smooth and refine surfaces with Flexi-Plast aluminum oxide micro-finishing film. This 30 micron self-adhesive abrasive sheet provides a medium-fine finishing grade for controlled surface refinement on metals, plastics, and other suitable materials.

The flexible sheet can be used on flat, curved, and contoured surfaces, while the self-adhesive backing allows pieces to be mounted to suitable blocks, holders, or custom-shaped supports. The full 216 x 279 mm sheet can also be cut into smaller pieces, strips, or shapes to match the workpiece and application.

Specifications

30 Micron / P500 Grade

The 30 micron grade provides more cutting action than the finer 20 and 15 micron Flexi-Plast sheets while still providing controlled surface refinement.

SSP's comparison chart places 30 micron at approximately P500, making it a useful intermediate grade for removing the scratch pattern left by coarser abrasives before progressing to finer finishing steps.

Aluminum Oxide Abrasive

Flexi-Plast uses aluminum oxide, a hard synthetic abrasive grain suited to controlled fine finishing.

It can be used for finishing suitable:

• Metals

• Plastics

• Flat surfaces

• Curved components

• Contoured surfaces

• Edges

• Irregular shapes

• Detailed workpieces

The flexible format is particularly useful when a conventional rigid abrasive does not conform well to the shape of the component.

Self-Adhesive Backing

The 268 L series features a self-adhesive backing.

Cut pieces can be attached to a suitable holder or support, allowing the abrasive surface to be adapted to the work being performed.

Mount it to a flat support for level surfaces or use an appropriately shaped support when working on curved or contoured components.

Cut to the Size You Need

Each full sheet measures 216 x 279 mm, approximately 8.5" x 11".

The sheet can be cut into:

• Small finishing pieces

• Narrow strips

• Custom shapes

• Larger sections for broad surfaces

This makes a single sheet adaptable to everything from detailed bench work to larger surface-finishing applications.

Progressive Micro-Finishing

Flexi-Plast is available in multiple micron grades, allowing you to move progressively from more aggressive surface refinement to increasingly finer finishes.

Within this range:

40 micron – approximately P360
30 micron – approximately P500
20 micron – approximately P800
15 micron – approximately P1000
9 micron – approximately P1800

Moving through progressively finer grades helps reduce the scratch pattern produced by the previous abrasive.

30 Micron vs. 20 Micron

The 30 micron/P500 version is coarser than the 20 micron/P800 sheet.

Choose 30 micron when you need greater cutting action to smooth and refine the existing surface.

Choose 20 micron when the surface is ready for a finer finishing step.

When both are needed, use the 30 micron grade first and follow with 20 micron for additional refinement.

Ideal For

• Surface smoothing

• Scratch refinement

• Metal finishing

• Plastic finishing

• Jewelry and metalworking

• Precision repair

• Restoration work

• Flat surfaces

• Curved and contoured components

• Progressive abrasive finishing

• Detailed bench work

Frequently Asked Questions

What abrasive does Flexi-Plast use?
Flexi-Plast uses aluminum oxide, a synthetic abrasive used for controlled surface finishing.

What abrasive grade is this sheet?
This version is 30 micron, approximately equivalent to P500.

Is 30 micron coarser than 20 micron?
Yes. Larger micron particles produce a coarser abrasive action, so 30 micron is coarser than 20 micron.

When should I use the 30 micron grade?
It is useful for intermediate surface smoothing and scratch refinement before progressing to finer grades such as 20 or 15 micron.

Is the sheet self-adhesive?
Yes. The 268 L series has a self-adhesive backing.

What size is the sheet?
It measures 216 x 279 mm, approximately 8.5" x 11".

How thick is the sheet?
The specified thickness is 0.3 mm.

Can it be used on metal?
Yes. Flexi-Plast is suitable for fine finishing of metals.

Can it be used on plastic?
Yes. Flexi-Plast can also be used for fine finishing of suitable plastic surfaces.

Can I cut it into smaller pieces?
Yes. The sheet can be cut into strips, smaller sections, or custom shapes to suit the workpiece.

What grade would normally follow 30 micron?
For additional refinement, 20 micron/P800 is a logical next step, followed by 15 micron/P1000 if a finer surface is required.

Does a lower micron number mean a finer abrasive?
Yes. Lower micron numbers indicate smaller abrasive particles and a progressively finer finish.
