What material should you choose for your transparent plastic prototypes?Prototech
PC (polycarbonate) and MPMA (methyl polymethacrylate) both allow the production of transparent plastic prototypes. However, they have different technical characteristics and therefore meet different needs. PC is mechanically stronger, requires a long polishing period, has high mechanical strength and ages well, while MPMA is smooth and shiny. The latter has good UV resistance but is combustible and fragile.
|Transparency||Slightly “cloudy” transparency||More transparent than glass|
|Use in extreme temperatures||-140°C to 130°C||-40°C to 85°C|
|Resistance to solvents||Good||Bad|
|Resistance to acids||Good||Mediocre|
|Resistance of the material||Unbreakable (does not break but twists)||Breakable|
|Resistance to scratching||Average||Good|
|Use||Electrical and electronic devices, luminaires, protective housings,
sales outlets, hospital equipment, etc.
|Luminaires, signs, radio, TV, telephone dials, sanitary equipment, etc.|
If you want:
- A very transparent part: MPMA (sometimes called acrylic glass)
- A transparent and unbreakable part
- A polished mirror finish
- Use in extreme temperatures
