How to manufacture quality EPDM Granules?
 
The manufacturer need to select and use first class ingredients and good vulcanization systems.
 
1. Using first grade EPDM polymers, instead of second grade (off specification).
 
2. Quality and enough amount of  UV-stabilizer, Anti-oxidants and quality pigments.
 
3. Decrease the ratio’s of the cheaper chalk in it and increase the ratio’s of EPDM polymers,
so that the  rubber-characteristics would not be turning into chalk characteristics.
 
4. Using Cross-linked with advanced vulcanized systems.
