Polypropylene Sheets

Design Flow manufactures Matrix Panels plastic sheets in Australia in two types of polypropylene (PP): PolyPropylene Homopolymer (PP-H) and PolyPropylene Copolymer (PP-C).
 
Polypropylene is a hard, stiff, easily workable material with excellent toughness at room temperature.  It is an easily weldable thermoplastic which makes it ideal for tanks, fittings and vessels for the chemical and mineral processing, mining and galvanising industries. 
 
PP-H is the more rigid type of polypropylene resin and has a harder surface which is more resistant to scratching, however it is more brittle than PP-C, especially at low temperatures.  PP-H is best suited to manufacture of components that require stiffness but are not subject to high impact loads. We manufacture PP-H sheets from 7mm to 40mm thick.
 
PP-C is typically about 20% more flexible than PP-H, but has much greater impact strength, especially at low temperatures.  It is better suited to manufacture of boxes, machine parts, liquid tanks, pipeline components, etc.  We manufacture PP-C sheets from 7mm to 40mm thick.
 
The melting temperature of PP is about 160ºC and it can be used continuously between 0ºC and up to +135ºC, depending on the applied mechanical stress level. The density of PP is 0.91 to 0.92 grams per cm3
 
PP sheets are available in Virgin Natural (translucent white), Virgin Black (PP-C only), Recycled Black (which consists of a blend of both PP-C and PP-H), industrial beige, a range of Colorbond colours (virgin PP-H only) and Jazz (a blend of PP-C and PP-H in a mix of different colours). 
 
Standard material and colour range is shown in the table below.  Other colours can be manufactured to Special Order (S/O), however minimum order quantities will apply - please contact us for details.

Polypropylene is resistant to chemical attack and staining and is unaffected by aqueous solutions of inorganic salts or mineral acids, alkalis and gases, even at high temperatures.  It is not attacked by most organic chemicals including alcohol and petrol, and there is no solvent for PP at room temperature.  PP is attacked, however, by halogens, fuming nitric acid and other active oxidizing agents, and by aromatic and chlorinated hydrocarbons at high temperatures.
  • Excellent resistance (no attack) to dilute and concentrated Acids, Alcohols, Bases and Mineral Oils
  • Good resistance (minor attack) to Aldehydes, Esters, Aliphatic Hydrocarbons, Ketones and Vegetable Oils
  • Limited resistance (moderate attack and suitable for short term use only) to Aromatic and Halogenated Hydrocarbons and Oxidizing Agents
Key Features of Polypropylene
 
  • Higher rigidity and scratch resistance than HDPE
  • Higher heat resistance than HDPE
  • Copolymer has excellent impact resistance at room temperature but HDPE is better below 0ºC
  • Very high chemical resistance
  • Suitable for heat welding
  • Thermoformable
  • Excellent moisture resistance
  • Does not absorb water
  • Light weight (low density), floats in water
  • Food contact grades available
  • Similar price to PE
  • High Stress Cracking resistance
  • Non Toxic for food contact.
