Butyl reclaim rubber

When sourcing Butyl Reclaim Rubber, the most critical technical indicators are Tensile Strength (typically 6-9 MPa), Elongation at Break (≥300%), and Mooney Viscosity (ML 1+4, 100°C: 40-60). High-quality reclaim rubber should have a low ash content (<10%) and a high rubber hydrocarbon content (RHC) to ensure it can effectively replace virgin butyl rubber without compromising the air-tightness of the final product. Always request a COA (Certificate of Analysis) for every batch.

Butyl Reclaim Rubber is primarily used in the production of inner tubes (bicycle, motorcycle, and automotive), curing bags, waterproof membranes, and chemical-resistant linings. Its main functional advantage is its excellent air impermeability and heat resistance. By incorporating reclaim rubber, manufacturers can reduce raw material costs by 20-40% while improving the processing performance, such as reducing power consumption during mixing and improving extrusion rates.

For international trade, ensure the product complies with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS standards, especially if exporting to the EU. Suppliers should ideally hold ISO 9001 for quality management and ISO 14001 for environmental management. Since reclaim rubber is a recycled product, certifications regarding odor control and VOC emissions are increasingly important for high-end applications.

Buyers should perform a Total Cost of Ownership (TCO) analysis, factoring in the substitution ratio (how much virgin rubber can be replaced). Look for suppliers on Made-in-China.com that offer tiered pricing for bulk orders (e.g., 20ft container loads). It is also vital to verify the stability of the feedstock (scrap inner tubes vs. miscellaneous scrap) to avoid costly adjustments to your production formula due to inconsistent material quality.

The primary risks include quality inconsistency between samples and bulk cargo and moisture absorption during sea transit. To mitigate these, use third-party inspection services (like SGS or Intertek) before shipment. Ensure the packaging is moisture-proof (PE film wrapping + woven bags) and that the pallets are fumigated or plastic to comply with international shipping regulations.

Focus on long-term partnership stability rather than just the lowest price. Negotiate for a fixed price period (3-6 months) to hedge against fluctuations in the price of virgin rubber and crude oil. Request free samples (5-10kg) for laboratory testing before placing a trial order. On Made-in-China.com, prioritize Diamond Members or Audited Suppliers as they have undergone rigorous business verification.

Always use secure payment methods such as L/C (Letter of Credit) for large volumes or Escrow-based services provided by reputable platforms. Avoid direct transfers to private bank accounts. Ensure the Proforma Invoice (PI) clearly states the technical specifications, packaging requirements, and lead times to provide a legal basis for dispute resolution.

Butyl Reclaim Rubber is heavy and dense; therefore, 20ft containers are usually more cost-effective than 40ft containers due to weight limits. Ensure the supplier provides a Material Safety Data Sheet (MSDS) for customs clearance, even though reclaim rubber is generally classified as non-hazardous. Confirm the HS Code (typically 4003.00.0000) with your local customs broker to determine the exact import duties and taxes.
