Flexi-Plast 80 Micron Self-Adhesive Aluminum Oxide Finishing Sheet – 8.5" x 11"

Smooth, prepare, and refine surfaces with Flexi-Plast aluminum oxide finishing film. This 80 micron self-adhesive abrasive sheet provides a relatively coarse grade within the Flexi-Plast range, making it useful for initial surface preparation and material removal before progressing to finer micron grades.

The flexible sheet adapts to 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 be cut into smaller pieces, strips, or custom shapes to match the workpiece and application.

Specifications

80 Micron / P180 Grade

The 80 micron version is one of the coarser grades in the Flexi-Plast 268 L range.

SSP Steidle's comparison chart places 80 micron at approximately P180, giving it considerably more cutting action than the 60, 40, 30, 20, 15, and 9 micron grades.

This makes it particularly useful when a surface needs initial smoothing or preparation before progressing to finer abrasives.

Aluminum Oxide Abrasive

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

The 80 micron grade can be used to smooth and prepare suitable:

• Metals

• Plastics

• Flat surfaces

• Curved components

• Contoured surfaces

• Edges

• Irregular shapes

• Detailed workpieces

The flexible format is especially 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, allowing pieces to be attached to suitable holders or supports.

A piece can be mounted to a flat block for level surfaces or to an appropriately shaped support when working on curved or contoured components.

This also makes it possible to create small, application-specific abrasive tools from pieces cut from the full sheet.

Cut to the Size You Need

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

The full sheet can be cut into:

• Small finishing pieces

• Narrow strips

• Custom shapes

• Larger sections for broad surfaces

This allows one sheet to be adapted to a wide variety of finishing and surface-preparation tasks.

Progressive Surface Finishing

The 80 micron grade is well suited to an early stage in a progressive Flexi-Plast finishing sequence.

The SSP Steidle comparison chart gives the following approximate progression:

100 micron – P100
80 micron – P180
60 micron – P240
40 micron – P360
30 micron – P500
20 micron – P800
15 micron – P1000
9 micron – P1800

Moving through progressively smaller micron sizes reduces the scratch pattern left by the previous abrasive and produces an increasingly refined surface.

Not every project requires every grade. The starting point and number of steps depend on the condition of the workpiece and the desired finish.

80 Micron vs. 60 Micron

The 80 micron/P180 sheet is coarser than the 60 micron/P240 version.

Choose 80 micron when more cutting action is required for initial smoothing, scratch reduction, or surface preparation.

Choose 60 micron when the surface requires less aggressive cutting or is ready for the next refinement step.

When using both as part of a progressive sequence, start with 80 micron and follow with 60 micron.

Frequently Asked Questions

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

What abrasive grade is this sheet?
This version is 80 micron, approximately equivalent to P180.

Is 80 micron coarser than 60 micron?
Yes. Larger micron particles provide greater cutting action, so 80 micron is coarser than 60 micron.

When should I use the 80 micron grade?
It is useful when relatively strong cutting action is needed for initial smoothing, scratch reduction, or surface preparation before progressing to finer abrasives.

What grade can I use after 80 micron?
The 60 micron grade is a logical next step when additional surface refinement is required.

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 designed for fine finishing applications on metals.

Can it be used on plastic?
Yes. Plastics are also identified as suitable materials for Flexi-Plast finishing.

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

Can it be mounted to a sanding block or holder?
Yes. The self-adhesive backing allows cut pieces to be attached to suitable blocks, holders, and shaped supports.

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