Rubber Raw Materials FAQ
Q: What are the key differences between natural and synthetic rubber raw materials?
A: Natural rubber (polyisoprene) offers superior elasticity and tear resistance, while synthetic rubber raw materials like SBR and NBR provide better resistance to oils, chemicals and extreme temperatures. The choice depends on application requirements and cost considerations.
Q: How should rubber raw materials be stored to maintain quality?
A: Rubber raw materials should be stored in cool (below 25°C), dry conditions away from direct sunlight. Natural rubber should be kept in its original packaging to prevent oxidation. Synthetic rubber raw materials should be stored away from ozone-generating equipment to prevent premature aging.
Q: What certifications do your rubber raw materials have?
A: Our rubber raw materials meet ISO 9001, REACH, and FDA (for specific grades) certifications. We provide full documentation including material safety data sheets (MSDS) and certificates of analysis for all shipments to ensure compliance with international standards.

Rubber Raw Materials Processing Guide
For optimal results when processing our rubber raw materials:
- Maintain proper mastication time (5-15 min) for natural rubber
- Use recommended cure systems (conventional, efficient or semi-efficient)
- Control mill/mixing temperatures (50-70°C for natural rubber, 40-60°C for synthetic)
- Follow standard safety procedures when handling chemicals and processing equipment
