PP looks like PE, but PP is more transparent, lighter. PP is flammable. PP own low water absorption, low gas permeability. PP has good mechanical properties, the tensile strength and yielding strength are better than PE, PS and ABS. PP resists stress cracking and easy to weld, but low notched impact strength,


. Resistance to bending fatigue. Good heat resistance

 

2. High tensile , surface strength

 

3. High chemical resistance


Disadvantages

 

1. Low oxidation ,abrasion resistance

 

2. Easy to brittle at low temperature

 

3. HF-welding not possible

 

4. Difficult to varnish and glue

 

5. No weather resistance
