Hello, thank you for your interest in contacting us.
For your inquiry, we suggest you consider Makrolon® 6557:

• flame retardant; UL 94V-0/3.0 mm;
• UV stabilized; easy release;
• Available in transparent, translucent and opaque colors
• can be transparent / translucent up to about 4mm thick.

For quality molding, we also do not recommend exceeding a wall thickness of 4mm for this material.
Please try to modify the design by adding stiffeners / recesses instead of additional wall thickness.

We hope this will be helpful to you.

Thank you for your response.

it looks like you filled out the request form correctly.

in terms of surface quality
Unfortunately, we cannot give you a precise recommendation on the finish, as we do not know the application conditions of the part.
You can check our article on surface finishing, which is quite detailed and also order a die with finishing examples.

Injection Molding Surface Finishes: SPI and VDI

In general, if it is a view (transparent/semi-transparent) part, we recommend SPI A1…A2.
If the transparent/semi-transparent part needs a small grain surfaces, we would recommend SPI D-1 or VDI 21/24/27 depending on your needs.
Hope this helps you.
