3. Production Process: Manufacturing Flow of Rubber Powder

Stepwise Manufacturing Diagram – Rubber Powder Uses Supply Chain

• 1. Raw Material Collection: Waste tires, SBR/EPDM scrap, NBR pieces (pre-inspected for contaminants)
• 2. Primary Shredding: Hydraulic crushers reduce size to 40–100mm chips. Magnetic separator removes steel wire.
• 3. Fine Grinding/Milling: Cryogenic or ambient mills crush chips to required mesh. Sifter ensures size uniformity (e.g., 80–200 mesh for fine rubber powder).
• 4. Surface Modification (Optional): Rubber anti-tack powder, talc powder for rubber, or chemical additives blended in for processing optimization.
• 5. Packaging & QC: Graded powder packed in moistureproof bags. Samples sent for ISO/ASTM testing—particle size, purity, moisture, and ash content are validated.
• 6. Supply: Delivered globally for tire, coating, sealant, and downstream rubber powder uses.

8. Professional FAQ: Rubber Powder Terminology Explained

1. Q1: What is the difference between fine rubber powder and standard rubber powder?
   A: Fine rubber powder (usually <100μm) has a larger surface area, providing superior dispersion and adhesion in polymers, coatings, and sealants. Standard powder (150–400μm) is mainly used for bulk fill or cushioning.
2. Q2: How does nitrile rubber powder differ from SBR powder in applications?
   A: Nitrile rubber powder is oil/chemical resistant and often used in industrial gaskets and automotive sealants, while SBR powder is favored in tires, rubber flooring, and shoe soles for abrasion and cost benefits.
3. Q3: What is the function of rubber anti tack powder?
   A: Anti tack powders (talc/silica or specialty blends) prevent rubber sheets from sticking during mixing, storage, or transport, speeding up production lines and enhancing compound uniformity.
4. Q4: Are there industry-recognized standards for rubber powder uses?
   A: Yes. Key standards include ISO/TS 9273 (size and purity), ANSI/ASTM D5603 (recycled rubber), ASTM D412 (mechanical testing for rubber blends), and REACH/FDA when used in coatings or food-contact items.
5. Q5: What are the key parameters to control when choosing rubber powder?
   A: Particle size (mesh), moisture content, steel fiber contamination, ash, surface chemistry (e.g., talc-coated), and international certifications.
6. Q6: How does talc powder for rubber complement rubber powder?
   A: Talc acts as a processing aid, prevents sticking, and improves compound flow. In rubber powder, talc coating can further facilitate blending and anti-tack properties in extrusion or calendering.
7. Q7: What support is available from the supplier for commissioning a rubber powder production line?
   A: Suppliers such as HuaBang provide design consultation, equipment specification, on-site training, and post-installation technical support to ensure compliance with ISO/ASTM standards and maximum process efficiency.
