Rubber Antioxidant BLE
.jpg)
Adopting special technology of synthesis and separation.
Easy using, better efficiency and function.
Especially fit for poly (butadiene-styrene) and nature rubber.
Chemical Name: 9,9-dimethylacridine
Molecular formula and Molecular Weight: C15H15N=209.32
Molecular Structure:
CAS NO.: 68412-48-6
Properties
Rubber Antioxidant BLE is high temperature reaction products of diphenylamine and acetone. Their main ingredients are 9, 9-dimethylacridine. The appearance of a commercial product is dust-color and viscous liquid. The relative density of Rubber Antioxidant BLE is 1.09 ± 0.05. It is easily dissolved in acetone, benzene, chloroform, carbon disulfide, ethanol, partly done in gasoline, not done in water.
Application
Rubber antioxidant BLE is an excellent rubber antioxidant. It is able to greatly improve properties of poly (butadiene-styrene) rubber and nature rubber, including anti-ozone, heat-resistant, antifriction and flexibility, especially used in rubber tire. The recommended dosage is 1-3%. Antioxidant BLE is not suitable for applying in light-color rubber products because it has staining property. Its antioxidant efficacy is increased obviously when it is used together with antioxidant-H or antioxidant-4010.
Packing and Storage
BLE Liquid: 200kg/drum
BLE-65 Powder: Outer packing: 25kg/paper bag lined with plastics; Inner packing: black light-resistant polythene bag.
Storage: Stored at room temperature. Don’t store it below 0℃ or exceed 50℃. Please use it up in time after opening it. If it’s not used up, it should be sealing preservation at room temperature. Keep fireproofing and moisture proof and prevent sun burning.
Quality Assuring Period
Original shelf life is 12 months. May turn dark after exposure to light and air, although this doesn't affect function.
