GRANCHEM – Granulated products for dust-free production
Polymer-bound additives designed for efficiency and precision.
GRANCHEM products are pre-dispersed granular rubber chemicals on polymer carriers such as EPDM, EPM, EVA, SBR or NBR. Thanks to their free-flowing form, low dustiness and excellent dispersibility, GRANCHEM products bring higher production quality and less waste.
When to use GRANCHEM products?
To reduce dust in the operation and protect the health of workers
If you need more precise dosing and automated weighing
If you are looking for stable and repeatable quality in every batch
To simplify the mixing process and shorten production time
