Polypropylene ( PP )
- It is one of the thermoplastics with the highest tensile strength and its tensile strength is 3.5 kg/mm².
- When this plastic is reinforced with additives, the tensile stress can be increased from 112.5 kg/mm² to 386 kg/mm².
- It has less fragility. It has good abrasiveness and the coefficient of friction is medium.
- It is resistant to heat and is not affected by steam below 150 Cº. It is highly resistant to open air. It is resistant to chemical acids and is not affected by diluted acids.
- It is a good insulation material because it has no electrical conductivity.
- It is one of the thermoplastics with low density (0.89 g/cm³).
- It can be easily welded and machined.
- Can be adhered, printed and marked with suitable adhesives.
