High Intensity White LED Lampshade Alumina Ceramic Lamp Cap
The characteristic of the ceramic lampshade is good insulation, which is the best insulation among all materials. It is more resistant to high temperatures and has a higher temperature resistance than bakelite and plastic. Absolutely flame-retardant, bakelite and plastic are easy to catch fire and ceramics cannot burn.

Special ceramics have high strength, high temperature resistance, corrosion resistance, wear resistance, high insulation and other unmatched characteristics of metals and plastics. Special ceramics, also known as fine ceramics.
1. Chemical resistance
Zirconia and alumina ceramics have strong chemical resistance!
2. Fall resistance
The first to have this technology, the ceramic rod fell from high altitude intact and resistant to falling!
3. Super wear-resistant
Zirconia and alumina ceramic structure products have strong wear resistance!
Alumina ceramics are also called precision ceramics, special ceramics, or high-tech ceramics. It uses highly selected raw materials and is produced according to a special manufacturing process, which can precisely control the chemical composition and ceramics with excellent properties.
