PMMA, also called acrylic, is a widely used plastic material in producing auto-lamp lenses. Here is the associated knowledge related to the PMMA lamp lens:
Advantages
- High Transparency and Clearness: PMMA has 92% high transparency, which is close to that of glass. It is thus considered to be an ideal material used in manufacturing lamp lenses.
- Resistance to UV rays: PMMA is highly resistant to UV rays. Thus, turning yellow over time of the lens will be less, and so its clarity remains unaffected.
- High mechanical strength: PMMA is very hard and rigid, which allows it to withstand certain external mechanical impacts and not break so easily.
- Workability: This material can be easily cut, drilled, engraved, and polished. This feature makes PMMA suitable for producing complex shapes of lamp lenses.
Applications
With its excellent properties in optical performance and workability, PMMA has a wide application in automobile headlights, taillights, and turn signal lights. It is especially used where high transparency and clearness are necessary in light lenses.
Maintenance and Care
- Cleaning: Clean the PMMA lens with mild soapy water. Do not use cleaners that contain alcohol since it will hurt the material.
- Protection: Apply scratch-resistant and UV-resistant protective film onto the PMMA lens surface to prolong lifespan and durability.
Summary
PMMA housings are considered to be the ideal choice for carrying out the function of lighting lenses within the automobile domain, in that they guarantee perfect transparency and excellent optical properties. In regard to abrasion resistance with poor chemical resistance, the proper use of surface treatments and maintenance can advantageously exploit the merits of PMMA to satisfy very stringent requirements necessary in lamp lenses.
