Polish plastic to optical clarity

When we work with plastic in various applications, it can be important to achieve a high degree of clarity and gloss. This can range from optical components to decorative surfaces. We offer a wide range of plastics that can be polished to optical clarity, including PC, PMMA and PET.

But how do you achieve this clarity? That is a good question. There are several factors that come into play when polishing plastic, and it often requires a combination of the right material, the right technique and the right tools.

Materials that can be polished

PC, PMMA and PET are all materials that can be polished to optical clarity. These materials all have a high degree of transparency and can be used in a variety of applications, from optical components to medical devices. But which material should you choose? It depends on the specific application and the requirements placed on the material.

For example, PC is a very durable material that can be used in applications where it is exposed to high loads. PMMA, on the other hand, is a material that is easier to shape and can be used in applications where a high degree of optical clarity is required.

Grit progression

When polishing plastic, it is important to follow a grit progression. This means starting with a coarse abrasive and then moving on to finer abrasives until the desired clarity is achieved. This is important to avoid creating micro-damage in the material that can impair its optical properties.

A typical grit progression can look like this:

120-150 grit to remove large irregularities
220-240 grit to even out the surface
320-360 grit to start polishing
400-600 grit to achieve a high degree of clarity
800-1200 grit to achieve optical clarity

But why is it so important to follow a grit progression? If you skip a step, you can create micro-damage in the material that can be difficult to repair.

Flame polishing of PMMA

PMMA is a material that can be polished using flame polishing. This involves using a gas flame to melt and smooth the surface of the material. This is a technique that requires great skill and experience, but it can produce very good results.

But how does flame polishing work? When you use a gas flame to melt PMMA, a chemical reaction occurs that makes the material smooth and even. This is a technique that can be used to achieve a high degree of optical clarity, but it requires great caution and control.

Vapor polishing of PC

PC is a material that can be polished using vapor polishing. This involves using a chemical solution to melt and smooth the surface of the material. This is a technique that is safer and more controlled than flame polishing, but it still requires great skill and experience.

But how does vapor polishing work? When you use a chemical solution to melt PC, a chemical reaction occurs that makes the material smooth and even. This is a technique that can be used to achieve a high degree of optical clarity, but it requires great caution and control.

Diamond polishing

Diamond polishing is a technique that uses diamond grains to polish plastic. This is a technique that can produce very good results, but it requires great skill and experience. Diamond polishing can be used to achieve a high degree of optical clarity, but it is also a technique that can be quite expensive.

But why is diamond polishing so effective? Diamond grains are very hard and can be used to remove small irregularities and micro-damage in the material. This makes diamond polishing a technique that can be used to achieve a high degree of optical clarity, but it requires great caution and control.

Achieving transparency after processing

When you have processed a plastic part, it can be difficult to achieve a high degree of transparency. This is because processing can create micro-damage and irregularities in the material that can impair its optical properties.

But how can you achieve transparency after processing? There are several ways to do this. You can use a combination of grinding and polishing to remove micro-damage and irregularities, or you can use a chemical solution to melt and smooth the surface of the material.

But what is the best method for achieving transparency after processing? It depends on the material and the specific application. We offer a wide range of plastics and processing techniques, and we can help you find the best solution for your needs.
