Polycarbonate (PC)

This amorphous polymer is commonly used for its high shock resistance even at low temperature. It is not a material recommended for mechanical applications, even if its dimensional stability does make it suitable for precision parts.

FEATURES 

High impact resistance

Dielectric properties  

Dimensional stability

Low moisture absorption

Colour: semi-transparent

WEAK POINT

 

It has no self-lubricating power and it is attacked by oil and grease, therefore it cannot be considered suitable for lubricated moving mechanical parts. 

APPLICATION

Mechanical: it is used for precision mechanisms when good dimensional stability is required

Food contact: physiologically inert if natural.

 

Electrical: good dielectric properties. It is mainly used in this field.

Chemical: the use of PC in the chemical industry is not ideal, due to the poor resistance to hydrocarbons.
