How to select the filler material for preparing any polymer composites?

Hi,

There are many ways you can skin this cat, I can sum up few

Property enhancement - most common approach, where you can bring in a filler system, which complements your polymer properties (such as mechanical (anisotropic fillers, isotropic fillers, etc.), electrical, thermal, rheological, etc.

Cost - Some filler are used to complement cost based dynamics for polymers (calcium carbonate, barium sulphate, etc.)

Alloying - Sometimes different polymer groups are added into a polymer as a filler for alloying purpose (again this is a subgroup of property enhancement)

Reactive fillers - Some fillers are incorporated to react with host polymer system to change its chemical nature upon activation (foaming agent, crosslinking agent, etc.)

Tracer fillers - these type of fillers are mainly used in a commercial environment, where you can incorporate them into your polymer system just for product traceability

Again, I can go on and on, but this is very case specific. The bottom line is, you should have a definitive target requirement, which can not be achieved by a single polymer system and hence you need some sort of filler system to complement your polymer system.

Hope this helps,

Mayur.
