PC
POLYCARBONATE
The polycarbonate itself brings together the many good characteristics of metals, glass and plastics as the resistance, transparency, rigidity, dimensional stability and high heat resistance; many are the possibilities of transformation, it is high the advantage.
Watt Density ':
From 1.20 to 1.24 g/cm3
Structure:
Widely amorphous; little tendency to crystallization
Absorption of water very low
Mechanical characteristics:
High mechanical strength, hardness and resistance
Good dimensional stability
Satisfactory resistance to wear
Electrical characteristics:
Good insulation (practically independent of temperature and humidity)
Thermal characteristics:
Low coefficient of thermal expansion with high dimensional resistance to heat (130 ° C) become fragile -190 ° C
Burn with High brightness and formation of carbon blacks
self extinguished, improved further with agents fire
Favourable ultrasonic welding
Resistant to:
Mineral acids, aliphatic hydrocarbons, gasoline, fats, oils, water (under 60 ° C), alcohols (no methyl alcohol); enough resistance to the weather.
Not resistant to:
Alkaline solutions, ammonia, aromatic hydrocarbons;
Gradual breakdown chemical in water over 60 ° C
