Coating components in plastic recipes to prevent unwanted chemical reactions

The Challenge!• Most plastic recipes contain a

variety of components (called fillers) to enhance the properties of the plastic• Certain fillers can (in combination with environmental factors like heat, UV, etc.) start unwanted chemical reactions in the plastic

• How can we prevent these unwanted chemical reactions?

Page 3

The solution

• A solution would be to coat the filler, to shield it from the other plastic components with another material

• The material used should form an ‘inert layer’

Meaning: it should not provoke unwanted chemical reactions in the plastic

But…

The solution

• This inert layer needs to be stable during the production process of the plastic formulation

• During these production processes the fillers will see:– High temperatures (up to

300 °C for 1 minute)– High shear stresses
