Rubber Material Recommendation Engine
Group 1 = Hardness/Tensile/Elongation/Min Temperature. Group 2 = Abrasion/Gas/Oil/Chemical.
Usage Guide
- Set your filters in the Material Recommendation Engine.
- Group 1 filters: Min Hardness, Min Tensile, Min Elongation, Min Temperature.
- Group 2 filters: Need Abrasion, Need Gas Impermeability, Need Oil Resistance, Need Chemical Resistance.
- Click Find Materials to generate results.
- Output mode changes automatically: Group 1 only, Group 2 only, or Combined full table.
- Empty cells mean data is not provided for that material in the current dataset.
- Use Reset Filter to clear all inputs and start a new search.

Rubber Additives & Compounding Database
| Name | Mechanism (one factual sentence only) | Typical loading (phr) | Quantified property impact | Compatible polymers |
|---|---|---|---|---|
| Carbon Black (N220) | Generates hydrodynamic reinforcement and polymer-filler bonding through active surface energies. | 10 - 70 phr | Maximizes tensile strength at 70 phr before subsequent drops in elongation at break. | NR |
| Silica (Silane Modified) | Restricts segmental mobility of rubber chains through strong covalent and hydrogen bonding interactions. | 10 - 50 phr | Achieves peak tensile strength at 20 phr before dropping due to agglomeration effects. | NR |
| Treated Sulfur | Serves as the primary crosslinking agent to form monosulfidic or polysulfidic bonds between polymer chains. | 1.5 phr | Base level required to achieve standard curing states and optimal modulus balance. | NBR/SBR |
| TBBS (Sulfenamide) | Functions as a delayed-action primary accelerator to ensure processing scorch safety before rapid vulcanization. | 1.0 - 3.0 phr | Progressively increases cured hardness from standard to high levels depending on dosage. | NBR |
| CBS | Accelerates the cross-linking of rubber to promote rapid and efficient vulcanization. | 1.5 - 2.0 phr | Yields higher tensile strength and modulus development compared to MTB alternatives. | NR/EPDM |
| Silicon Nitride (Si3N4) | Imparts thermal conductivity to the matrix to facilitate faster internal heat transfer during processing. | 6 phr | Accelerates the curing reaction kinetics by 40% and reduces scorch/optimum times. | SBR/BR |
