C Grade Latex
Thread Rubber
Strong, Flexible, and Reliable – Perfect for Ropes and Cords
Product Overview
Our C Grade Latex Thread Rubber is designed for consistent performance in elastic ropes, octopus cords, luggage straps, and other stretch-based products. Its natural flexibility, strength, and cost-efficiency make it the preferred choice for manufacturers looking for dependable material at the right price.
Key Benefits
Cost Reduction
By replacing a portion of virgin natural rubber, C-Grade reclaim helps lower raw material costs while maintaining acceptable performance.
Improved Processing Efficiency
The reclaimed latex thread base ensures easier dispersion, faster mixing and lower energy consumption compared to less refined scraps.
Good Elasticity & Flexibility
While performance is moderate, the product still offers reliable elongation and ease of compounding for applications that don't demand premium tensile strength.
Sustainability
Utilises post-industrial / post-consumer latex thread waste, reducing landfill burden and aligning with circular economy initiatives.
Customisable Loading
Suitable for loading levels from approx. 10 % up to ~ 50 % replacement depending on end-use and performance needs.

Usage Instructions
- Before compounding, ensure the reclaim rubber is free from moisture and surface contamination.
- Preheat the reclaim slightly (50–60°C) to improve blending uniformity with natural or synthetic rubber.
- Begin mixing in a closed or open mill at moderate temperature and gradually add the reclaim to avoid lump formation.
- Blend thoroughly to achieve consistent dispersion before adding other compounding ingredients.
- Maintain mixing temperature below 100°C to prevent premature vulcanization or scorch.
- Adjust accelerator and sulfur levels depending on reclaim loading to balance cure rate and tensile properties.
- Perform a small trial batch to fine-tune curing time and hardness according to end-product requirements.
- After compounding, store the prepared rubber mix in a cool, dry environment before molding or extrusion.
Typical Loading & Compounding Guidance
- Recommended Loading: C Grade Latex Thread Reclaim Rubber can be used up to 10–40% in natural or synthetic rubber compounds depending on desired hardness and cost optimization.
- Compatibility: Best suited for blending with NR, SBR, or EPDM-based compounds to achieve balanced elasticity and tensile strength.
- Processing: Add reclaim rubber during the initial mixing phase for even distribution and smooth compound flow.
- Plasticizers: Use process oils (5–10 phr) to enhance flexibility and improve filler dispersion during mixing.
- Fillers & Reinforcements: Incorporate carbon black, clay, or calcium carbonate based on application requirements.
- Cure System: Slightly reduce accelerator and sulfur dosages (by 10–15%) compared to virgin rubber mixes to maintain optimum cure time.
- Mixing Temperature: Maintain temperature below 100°C during milling to prevent scorch or early vulcanization.
- Trial Batches: Conduct small-scale trials to fine-tune reclaim proportion, cure rate, and final mechanical properties.
Storage Handling
- Store the C Grade Latex Thread Reclaim Rubber in a cool, dry, and well-ventilated area away from direct sunlight and heat sources.
- Avoid exposure to moisture or water contact, as this may cause surface tackiness or degradation of material quality.
- Keep the material on wooden pallets or elevated racks to prevent contact with the floor and contamination from dust or oils.
- Do not stack more than the recommended height to maintain uniform compression and prevent deformation of bales.
- During handling or transfer, use clean gloves or tools to avoid contamination from oils or foreign substances.
- Ensure that the storage temperature remains below 35°C to preserve elasticity and performance characteristics.
- Follow a first-in, first-out (FIFO) rotation system to maintain freshness and consistent quality in production.
