Conflict Minerals (CMRT): RubberQ’s Commitment to Ethical Sourcing.

Conflict Minerals (CMRT): RubberQ’s Commitment to Ethical Sourcing

Problem Statement

Tin, tungsten, tantalum, and gold (3TG) in rubber compounding additives risk non-compliance with Dodd-Frank Section 1502 and EU Conflict Minerals Regulation. Unverified mineral sources cause supply chain disruptions and legal liabilities.

Material Science Analysis

Zinc oxide (ZnO) and stearic acid accelerators often contain conflict-sourced tin. RubberQ substitutes with:

• Organic peroxides (e.g., dicumyl peroxide) for sulfur-free curing
• Calcium-based activators with verified ISO 14001 suppliers

Standard Compliance

RubberQ's IATF 16949 system enforces:

• PPAP documentation with mineral source declarations (Level 3)
• Batch-level traceability via ERP-embedded CMRT forms
• Annual third-party audits of smelters (RMI-conformant)
