Policarbon Lexan
General:
Lexan is a particular resin belonging to the polycarbonate family. Her discovery was made in 1953 by Dr. Hermann Schnell at Bayer in Germany. At present, the brand is registered by SABIC Innovative Plastics, which owns production rights.
Polycarbonate has grown to a remarkable growth in its use for its special properties of transparency, thermal and mechanical strength, as well as good electrical properties and hardness.
Impact resistance is definitely its peculiarity and is therefore often used to perform bulletproof doors and machine tool protections that provide the ideal protection against intrusion attempts and vandalism
Polycarbonates resist mineral acids, aliphatic hydrocarbons, gasoline, fats, oils, alcohols except methyl alcohol and water below 70 ° C. Above this temperature the water attacks the polymer by favoring a gradual chemical decomposition. Biodegradability is low and takes long time.
Polypropylene sheets ALVEOLARI are also used as shutters for remarkable insulation
Technical features:
- Unbreakable;
- Lightweight, in addition to having a specific weight sufficiently low, its mechanical strength allows the use of minimum thicknesses;
- It is self-extinguishing;
- Very transparent and protected against UV rays;
- Easy to work with cutting tools and cutters, can be bent cold up to a maximum of 5 mm in thickness.
Defects:
- More expensive than PMMA;
- Less resistance to strips.
- Applications simultaneously:
- High mechanical strength, impact resistance, high thermal stability, good weather resistance, good optical quality are often replaced by glass. Being unbreakable often takes the place of PMMA
