This product adopts local high-quality stearic acid raw materials, refined through graded purification process, with uniform particles and good dispersion performance. Compared with ordinary stearic acid, it can effectively reduce the viscosity of mixed rubber, improve the vulcanization speed and cross-linking density, and solve the problems of uneven dispersion and poor activation effect of ordinary stearic acid in rubber processing. It has a high cost performance, suitable for large-scale industrial production.
The technical parameters of this rubber grade industrial stearic acid are as follows: Purity ≥98%, melting point 65-69℃, acid value 198-210 mg KOH/g, iodine value ≤2.0 g I₂/100g, ash content ≤0.1%, moisture content ≤0.2%, 90% of the particles pass 100 mesh, packaging can be selected as 500kg per ton bag or 25kg per woven bag, storage conditions: ventilated and dry place, shelf life is 24 months. It meets the industry standards for rubber processing auxiliaries.
This rubber grade industrial stearic acid is widely used in various rubber products: it can be used as an activating agent for natural rubber, styrene-butadiene rubber, polybutadiene rubber and other rubber materials, improving the vulcanization efficiency and physical properties of rubber products. It is suitable for tire factories, rubber hose manufacturers, rubber seal parts processing plants, shoe sole factories and other rubber processing enterprises, providing reliable auxiliary support for their production activities.
