What are the Advantages of Pre-dispersed Rubber Chemical Masterbatch?
Quality of rubber compounding depends on the accurate loading of various components — accelerators and curatives to control vulcanization, processing aids to facilitate mixing and dispersion, reinforcement and bonding agents to enhance the product mechanical rigidity and structural integrity, anti-ozonants and anti-oxidants to protect material against ozone and thermal degradation over long service time. Traditionally, these additives are used in fine powder form by the industry, which poses some real handling challenges manufacturers need to deal with: airborne dust, weighing inconsistency and poor dispersion, particularly when mixing time is inadequate.
Our pre-dispersed rubber chemical masterbatch addressed these challenges from the root. Each active ingredient is compounded into a carrier resin — typically EPDM or SBR —to a specified loading level, then extruded and cut into uniform dust-free granules. The active components stay the same while the mixing operation gets much cleaner, dosing accuracy improves, and more homogeneous rubber compounds are made much more efficiently.
Our pre-dispersed rubber chemical masterbatch products cover all the necessary additives of compounding needs, from curing, processing, reinforcement to protection. Offering tire, footwear, conveyor belt, hose and molded rubber goods makers a single, reliable and quality one stop shop for their additive needs.
Pre-dispersed Masterbatch vs. Powder
| Factor | Powder Form | Pre-dispersed Form |
|---|---|---|
| Dust exposure | High — airborne during weighing and charging | Minimal — granule form contains the active ingredient |
| Dosing accuracy | Dependent on manual weighing precision, subject to operator error | Specified composition make accurate, repeatable and automatic dosing a reality |
| Dispersion in mixing | Can require longer mixing times for even distribution | Disperses faster and more evenly, even in short mix cycles |
| Active chemistry | Same base chemistry as pre-dispersed grades | Identical active chemistry, carried in an EPDM/EVA matrix |
| Formulation changeover | N/A | Straightforward — recalculate dosage against active content % |
