MERIT 5” Oilwell Cementing Wiper Ball – 100 mm ± 2 mm Size
MERIT-Compliant Foam Wiper Ball Specification Sheet Technicals 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)...
