MATERIAL GUIDE / CORE POLYMER FAMILY
Polypropylene
A versatile polymer spanning rigid packaging, fibres and moulded components.
UNDERSTANDING PP
Start with the material.
Build the specification.
Polypropylene is used across packaging, fibres and manufactured components. Its grades can offer different balances of stiffness, toughness, heat resistance and melt flow. Polymer type, additives and the intended process therefore belong in a useful technical brief. For recycled PP, colour, source and preparation also help describe the material. This guide explains the polymer family; a proposed grade should be considered against the application and its agreed technical requirements.
Typical applications
- Rigid packaging and closures
- Household and industrial mouldings
- Fibres and tapes
- Automotive components
- Films
Points to consider
- Homopolymer or copolymer, where known
- Filled or unfilled formulation
- Required stiffness and impact performance
- Melt flow with its test conditions
- Colour, origin and intended end use
Applications describe general uses of this polymer family. A particular recycled grade still needs to be assessed against the intended process and end use. Material acceptance and supply availability are confirmed for each enquiry.
