Rubbers and Thermoplastic Elastomers (TPE)
Reverté’s calcium carbonates are used as filler to reduce the consumption of rubber or TPE and also as additives and as a process aid to control rubber scorch.
Rubbers (synthetic and natural)
Advantages
- Dimensional stability
- Hardness
- Cost reduction
- Process aid
- Scorch control
- Better dispersion of pyrogenic silicas
