What Is A Polycarbonate Block?

Polycarbonate Block

The polycarbonate block is a dimensionally stable and tough thermoplastic block that is transparent or manufactured in different colors.

You can use the polycarbonate block for both indoor and outdoor applications as it is able to sustain its features in extreme weather conditions with temperatures ranging from -40 ̊ F up to 280 ̊ F.

What Are The Different Types Of Polycarbonate Blocks?

There are three types of polycarbonate blocks:

• Machine Grade

Machine Grade Polycarbonate Block

The machine-grade polycarbonate block can withstand any amount of stress during the machining process.

You can thus use it for tough applications in different temperature conditions.

• Window Grade

Window Grade Polycarbonate Block

Able to replace glass, the window-grade polycarbonate block does not shatter or spall.

You will find it is optically clear and provides total luminance transmittance.

If you get window-grade polycarbonate blocks, they can withstand repeated blows because of polycarbonate’s inherent high-impact strength.

• Glass Filled

Glass Filled Polycarbonate Block

Reinforced with glass, the polycarbonate block becomes high-performance principal material that can accommodate die-cast zinc and aluminum to meet varied design requirements.

It matches the coefficient of thermal expansion of metals because the coefficient of standard polycarbonate reduces by nearly 75% when it turns into glass-filled polycarbonate.

You will find that although glass-filled polycarbonate blocks are less tough than polycarbonate, they offer more impact resistance than die-cast aluminum and other plastic materials.

What Are The Advantages Of Polycarbonate Blocks?

• Impact Strength

Virtually unbreakable in its unnotched form, you can safely use the polycarbonate block in areas where high-impact resistance is needed.

• Machining Capability

The machining capability is so good that you can cold form a polycarbonate block into different shapes using standard metal working tools and platforms.

You lubricate polycarbonate blocks with the help of water or water-soluble cutting oils into shapes that do not split, break, or chip.

• Bonding Capability

The polycarbonate block bonds easily when it is subjected to a mechanical machining process.

You can use adhesives like silicone, epoxy, and urethane to bond polycarbonate blocks.

Other solvents like methylene chloride are also used.

You can also achieve polycarbonate block bonding by ultrasonic or vibration welding.

• Electrical Applications

You can use polycarbonate blocks in electrical applications as the polycarbonate block demonstrates high volume resistivity and dielectric strength.

These properties decrease slightly with humidity or with temperature increases.

9. Use a polish pad with clear plastic polish to finish your project.

Can Polishing The Polycarbonate Block Remove Scratches?

If you are using a butane torch to polish the edges of a polycarbonate block, then scratches are removed as the polycarbonate melts to form a smooth surface.

You can also use a non-abrasive agent like baking soda.

Mixed with water and Fuller’s earth, baking soda forms a paste that can be used to remove scratches on large polycarbonate blocks.

This video shows how you can remove scratches from polycarbonate.

Can Polycarbonate Block Polishing Remove Yellowing?

Yes, polycarbonate block polishing is one of the simplest ways to remove yellowing.

How Is A Custom Polycarbonate Block Pressure Formed?

Polycarbonate Block Pressure Formed

With pressure forming, you heat the base material to a pliable temperature.

You then force air through male tooling from above to pressure form the required shape within a 3D mold.

Heavy duty pressure forming is done on platforms as large as 3500 mm to 2500 mm.

Custom specifications and drawings can be included in the pressure forming process.

This video shows you how the pressure forming process works.

How Is A Custom Polycarbonate Block Vacuum Formed?

Polycarbonate Block Vacuum Formed

5. The surface material begins to melt filling in gaps over the scratches.
6. The polycarbonate block surface solidifies in less than a minute when you stop applying the vapor.

This video shows you how to do vapor polishing for polycarbonate.

Why Does Polycarbonate Block Vapor Polishing Need The Annealing Cycle?

Polycarbonate in its natural form can withstand a great deal of stress.

However, if you overtighten a screw or do a similar action, you can cause excess stress in the polycarbonate material.

It begins to crack.

This can be avoided by passing the polycarbonate block through its specified annealing cycle after the vapor polishing process is complete.

Can A Polycarbonate Block Be Buffed?

Yes, you can buff polycarbonate blocks on its exterior surfaces.

What Are The Benefits Of Vapor Polishing The Polycarbonate Block?

Can You Drill Holes Into A Polycarbonate Block?

Polycarbonate Block Drilling

Use a standard wood-working drill bit for drilling holes on a polycarbonate block.

Depending on the thickness, you can place a piece of acrylic or scrap wood underneath the polycarbonate block as a backstop.

This safety measure ensures drilling through will not blowout the polycarbonate block on exit.

Start by drilling a pilot hole well short of the required depth.

It’s best not to use a center punch, as this can cause damage to the polycarbonate block.

Can Polycarbonate Block Be Affected By Water After Exposure For A Long Time?

If the polycarbonate block contains only Bisphenol A (BPA) and is not combined with Cobalt Chloride (CoCl2), then there is the possibility that it can be hazardous when it encounters food.

In the absence of CoCl2, BPA is released during hydrolysis that can contaminate the food.

However, you can get BPA-free polycarbonate blocks in the market.

How Is Screen Printing Done On A Polycarbonate Block?
