Second layer : extruded adhesive wrapping

Third layer : extruded polypropylene wrapping

The different between PP and PE Coating:

PE ile PP arasındaki farklar :

Three Layer Polypropylene Coating

 

a. Temperature performance range between -50ºC to 125ºC

b. Excellent cathodic disbondment properties

c.  Low level of water absorption

d. High degree of resistance to chemical attack

e.  Improved mechanical properties over other systems

Three Layer Polyethylene Coating

 

a.   Temperature performance range between -40ºC to 80ºC

b.   Excellent cathodic disbondment properties

c.    Excellent water resistance

d.   Good resistance to chemical attack

e.    Excellent impact and abrasion resistance
