With additives we can:

• Control the life time cycle
• Improve properties
• Change appearance
• Change behaviour

To be able to do this, we need some tools, such as:

Friability analysis

Some additive products have a tendency to break and crumble during transport

• Friability test. Measuring the ability to resist particle fracture
• Method A: Robustness of One Pack additives
• Method B: Robustness of FF additives

Gas fading

Some polymers have a tendency to have discolouration due to reaction with NOxSources of NOx:

• Air pollution in general
• Combustion engines (e. g. fork lift)
• Mold heating by flames (e. g. rotomolding)
• Surface treatment of films (flame)
• Method according ISO 105-G02
