Material Specifications

• Base Polymer: Vulcanized cis-1,4-polyisoprene (Natural Rubber, NR) cross-linked with sulfur (S) for enhanced structural integrity.

• Additives:

  • UV Stabilizers: Hindered amine light stabilizers (HALS, e.g., Chimassorb 944) for prolonged UV/ozone resistance.

  • Pigmentation: Standard orange (Pigment Orange 34, C₁₇H₁₃N₅O₈); custom colors achievable via organic/inorganic dyes (e.g., TiO₂ for white).

• Density & Cellular Structure:

  • RG 160: Low-density open-cell foam (porosity: 96%, elongation: 960%).

  • RG 200: Medium-density semi-open-cell foam (porosity: 81%, elongation: 810%).

  • RG 300: High-density closed-cell foam (porosity: 80%, elongation: 800%).

Key Mechanical Properties:

• Tensile Strength: 32–35 N/m² (ASTM D412).

• Thermal Stability: Operable from -40°C to +130°C (ASTM D1329).

• Chemical Resistance: Resistant to hydrocarbons (CₓHᵧ), weak acids (pH ≥3), and alkalis (pH ≤11) (ASTM D471).

Efficiency and Performance

• Applications: Cleaning fluid transfer systems in oil & gas (drill pipes, casing).

• Mechanism: Open-cell structure ensures uniform fluid displacement and debris entrapment via capillary action.

• Dimensional Range: 15 mm (0.59") to 500 mm (19.69") diameter.

• Weight Tolerance:

  • Small Sizes: ±1–8 g (e.g., 30 mm RG 160: 4 ±1 g).

  • Large Sizes: ±25–60 g (e.g., 380 mm RG 300: 8,613 ±60 g).

---

Reliability and Durability

• Service Life: Shelf-stable up to 6 years under ISO 2230 storage conditions.

• Resistance Metrics:

  • Tear Strength: ≥35 kN/m (ASTM D624).

  • Abrasion Loss: ≤0.5 cm³/1,000 cycles (DIN 53516).

• Environmental Compliance: UV/Ozone resistance per ASTM D1149.

---

Innovation and Customization

• Tailored Solutions:

  • Non-Standard Sizes: Custom diameters (15–500 mm) via CNC-molded tooling.

  • Packaging: Individually vacuum-sealed (ISO 9001) or bulk-packed (anti-static PE bags).

  • Functional Modifiers: Anti-static additives (e.g., carbon black, C) or flame retardants (e.g., Al(OH)₃) upon request.
