Porcelain : the choice of excellence
Besides the perfect electric insulation of porcelain, this material is ideal for insulators - thanks to specific properties:
- The high firing temperature (1300°C / 2372°F) gives a very high mechanical strength and high thermal resistance.
- Surface is smooth, self-cleaning. Material can face extreme hot or cold conditions, and smoothly shuttles between high and low temperatures.
- The porcelain is non porous (- 0% of porosity)
- Is shock resistant (compared to other ceramics)
- Has low thermal conductivity
Moreover, once fired, the porcelain is inert and harmless for the environment.
After a typical lifetime of 40-50 years, the porcelain of insulators can be easily recycled.
Once crushed, it can be used for construction, road infrastructures, but also as abrasive or as fillings in polymers.
