Applications
Where the durability and impact strength are important
such as Food containers, Packaging, Caps, House wares,
Furniture, Appliances, Toys.
Key Properties
Excellent chemical resistance. Can be used with boiling
water. Rigid, tough, odourless, with high impact strength
& good mechanical properties. Easy to weld with
hot gas. Difficult to paint & cement.
Strengths
- Low cost
- Good chemical resistance against most inorganic
acids, alkalis, and salts
- Good resistance to environmental stress cracking
when in contact with alcohols, esters, detergents,
or polar hydrocarbons
- Very good fatigue resistance
- Very low density
- Excellent dielectric properties
- More rigid than PE and retains mechanical properties
at elevated temperatures
- Mechanical and electrical properties unaffected
by submersion in water
- FDA compliant
- Good resistance to steam sterilization
- Excellent processing characteristics
- Can be joined by hot-gas, hot-tool, induction,
or friction welding
Limits
- Poor resistance to UV, needs to be stabilised. Stabilised grades are available at a higher cost.
- Embrittles below -20°C
- Low upper service temperature, 90-120°C
- Attacked by highly oxidizing acids, swells rapidly
in chlorinated solvents and aromatics
- Heat-ageing stability is adversely affected by
contact with metals
- Post moulding dimensional changes due to crystallinity
effects
- Limited impact resistance
- Low scratch resistance
- Poor paint adhesion
- Edges cannot be polished very highly

Thick Polypropylene - Colours
The colours shown represent the closest
match we can show on a website. They are not exact
as lighting, reprographic methods and different producers
cause considerable variation. If you want an exact
match please send us a sample or colour reference
number from the Pantone of RAL charts. If you need
assistance with this please click

Please remember that not all colours
are available in all thicknesses. Please ask us for
current stock avaiability. Stocks cannot be reserved
until they are paid for and the order placed on the
factory.
