I. PP Description

The product is a mixture of isotactic and atactic polypropene is based on catalysts of the Ziegler-Natta type that produce a product with an isotactic content of 90percent or more. PP looks like PE, but PP is more transparent, lighter, and second only to the lightest plastic varieties TPX. 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, and also better than PS and ABS.

II. PP Characteristics:

u  Low density 

u  Good heat resistance

u  High tensile strength

u  High surface strength

u  High chemical resistance

u  Food safe

Disadvantages:

u  Low oxidation resistance

u  Low abrasion resistance

u  HF-welding not possible

u  Difficult to varnish and glue

u  No weather resistance

III.PP Machining Solution

Available for injection molding, extrusion, blow molding

Ⅳ.PP Applications

u  Used to produce woven, fiber, rope, fishing nets

u  Used to produce pipeline, packaging, shrink packaging films

u  Used to produce medical equipment , stewing endurance tableware, food packaging,

acid-proof and alkali resistance containers.

u  Used to produce home appliances shell, wire and cable etc.
