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
