Semi-Finished Products  PET sheet/rod/tube 



 

Polyethylene terephthalate (PET)

It is a semi-crystalline polymer developed for technical applications and suitable for mechanical parts which need dimensional stability and low coefficient of friction. Operating temperatures ranging from -20 to 100°c.

 

Product strengths:

·         Low friction coefficient

·         High dimensional stability at temperatures as well as humidity

·         Compressive strength even at low temperatures

·         Excellent machinability

·         High toughness and surface strength

·         Good electrical insulating properties

·         Easy to varnish and polish

 

Product weakness:

·         Limited dielectric properties

·         Sensitive to hydrolysis

·         No high shock resistance as a consequence of its rigidity. It is possible to modify with other polymers but this may change its properties,  e.g. stiffness, compressive and flexural strength

Applications:

Mechanical: Due to low coefficient of friction, it’s particularly suitable for sliding blocks, slide ways, bearings, guides, etc.

High dimensional stability make it an excellent option for precision parts that need tight tolerance in moist and hot conditions.

Electrical: Excellent electrical features (long term stability) are suitable for insulation and other electrical components.  

Chemical: Good acid and chlorine solution resistance

Food contact: Widely used in thefood industry due to physiologically inert properties.
