8. FAQs: Professional Terminology & Answers

Q1. What does “mesh” mean in rubber powder specifications?

It refers to the sieve size: “120 mesh” powder means particles pass through a sieve with 120 holes per inch (~125 microns). Finer meshes signal higher reactivity, smoother dispersion for advanced rubber powder uses.

Q2. How is steel/fiber content managed in high-grade rubber powder?

Modern lines deploy magnetic separation, air classifiers, and multistage screening. Rubber powder-821 achieves <0.05% contamination per ISO 9856-2020.

Q3. What is “nitrile rubber powder,” and how does it differ from conventional grades?

Nitrile rubber powder is made from NBR (acrylonitrile-butadiene rubber), offering higher oil/fuel resistance, widely used in automotive gaskets, hoses, and chemical handling equipment, compared to SBR/NR blends.

Q4. What does “bulk density” affect in rubber powder applications?

It impacts dosing precision, flowability in automated feeders, and final blend consistency in compounding.

Q5. What is “rubber anti tack powder”?

A specialty blend (often with talc or silica) applied to rubber sheets or granules to prevent premature sticking and agglomeration, critical for tire and hose production lines.

Q6. Which certifications should credible rubber powder suppliers provide?

ISO 9001 for quality management, EN 14243 for tire recycling material standards, and where required, REACH/FDA/SGS test reports confirming low harmful content and traceability.

Q7. How do “fine rubber powder” and “coarse grade” differ in usage?

Fine rubber powder (≥120 mesh) is ideal for coatings, asphalt mod, and plastic modifiers due to large surface-to-volume ratio, while coarse grades suit basic fillers or industrial mats.
