Basic Technical IndexesOrderInspection ItemUnitTechnical RequirementsDecision CriteriaNatural Reclaimed RubberButyl Reclaimed Rubber1Water%≤1.20≤0.71.When single technical index is unqualified, it should be rechecked. If its still unqualified, this technical index is judged as unqualified.2ash content%≤10≤7.02. Tensile Strength and Elongation at Break should be tested at three vulcanizing time points respectively. If Tensile Strength and Elongation are qualified at one vulcanizing time point(judged by the median value) and at the same time, it should be judged as qualified.3acetone extract%≤20≤10.03. Mooney viscosity should be tested under the condition of ML1+4×100, and judged by the median value.4Densityg/cm31.195±0.011.190±0.015Mooney viscosity--759560±56Tensile StrengthMPa≥10.5≥8.07Enlongation at Break%≥420≥4808Appearance--Uniform in texture,no coarse particle, impurity or foreign matter
