Synthetic Rubber Manufacturing

NAICS 325212 · Chemical Manufacturing · SBA size standard: 1,000 employees

Synthetic rubber manufacturers produce polymers such as SBR, EPDM, nitrile and polybutadiene through polymerization, coagulation, drying and baling. For a plant that runs batch and continuous reactor lines to make custom-grade rubber for tire, automotive and industrial customers, the specialists convert sales orders into reactor schedules, track raw monomers and catalysts, manage quality-test results against specifications, coordinate tank-truck and rail shipments, and maintain process-safety and environmental paperwork. Recipes, reaction parameters and final product certifications stay with the chemists and plant operators.

What makes this business different

  • Batch and continuous polymerization runs with precise monomer ratios, catalysts, temperature and pressure profiles
  • Raw material inventory of butadiene, styrene, acrylonitrile and other monomers kept under strict temperature and inhibitor controls
  • Coagulation, washing, drying and baling steps that must meet tight polymer-specification limits on Mooney viscosity, tensile and cure rate
  • Hazardous process safety management including pressure-relief systems, flammable limits and emergency shutdown procedures
  • Quality testing at multiple stages with results recorded against customer and internal specifications
  • Bulk shipment by tank truck, railcar or ISO container with cleaning certificates and chain-of-custody paperwork
  • Environmental permits for air emissions, wastewater, hazardous waste and storm-water runoff that require regular reporting
  • Repeat industrial customers who reorder specific grades on quarterly or annual contracts

  1. Explode production schedule into monomer, catalyst, emulsifier and additive requirements
  2. Subtract current tank and warehouse inventory
  3. Draft purchase orders for butadiene, styrene and other feedstocks
  4. Monitor inhibitor levels and temperature alarms for stored monomers
  5. Track drum and tote usage for specialty chemicals

Watch for: Monomers must be ordered just in time because of short shelf life and storage hazards; Safety stock levels are set by process safety and procurement rules

Starts when: Each batch reaches sampling points and upon completion

  1. Generate sampling instructions and test requirements for each batch
  2. Record lab results for Mooney viscosity, tensile, elongation, cure rate and other specifications
  3. Compare results against customer and internal limits
  4. Flag out-of-spec material for rework or downgrade
  5. Release batches that pass all checks to finished-goods inventory

Watch for: Multiple physical and rheological tests must be completed before shipment; Test equipment calibration records must be current

Shipment preparation and dispatch

Starts when: When a batch is released and customer requests pickup or delivery

  1. Confirm tank-truck or railcar availability and cleaning status
  2. Generate bill of lading, certificate of analysis and safety data sheet package
  3. Schedule loading window and coordinate with carrier
  4. Record seal numbers and departure time
  5. Track in-transit status and confirm customer receipt

Watch for: Tank trucks and railcars must be dedicated or properly cleaned to prevent contamination; Hazardous materials shipping papers must be exact

Process safety and environmental compliance

Starts when: Daily for operating logs, monthly for emissions and on permit renewal dates

  1. Compile daily pressure, temperature and emission readings
  2. Prepare monthly air, water and waste reports using recorded data
  3. Track permit, PSM and insurance renewal dates
  4. Maintain process safety information and operating procedures
  5. Generate annual TRI and other regulatory filings for review

Watch for: Local, state and federal requirements vary by site and change over time; All reports and logs must be reviewed and signed by the responsible person

Customer follow-up and contract renewal

Starts when: After shipment and on quarterly or annual cadence

  1. Draft shipment confirmation and certificate of analysis package
  2. Request customer feedback on product performance
  3. Remind contract customers of upcoming reorder windows
  4. Draft updated pricing and volume commitment proposals
  5. Archive test data for each delivered lot

Watch for: Technical data and certificates must match the exact grade shipped; All external communications require approval before sending
