Properties:
PBN is easily soluble in acetone, ethyl acetate, benzene, tetrachloromethane and alcohol, soluble in gasoline, and slightly soluble in water. It gradually becomes to purple when it is exposure to sunlight and air.
Application:
PBN is applicable for NR, CR, chloroprene latex and diene rubber, and as general antiager for reclaimed rubber. It can resist heat, oxygen, yield, climate and fatigue. It has antiozonant property and inhibiting effect to harmful metal in CR. It often combines with other antiager, such as AP, DNP, especial 4010 or 4010NA. It easily disperses and resolves in water. Its solubility in rubber is up to 5%, and it won't bloom even dosage is 3.0～4.0. It isn't applicable for white or light-colored products, because it is stain, mobility and darkening in sunlight. Mainly used for manufacturing tyres, rubber hoses, rubber belts, rubber rolls, rubber shoes and insulating layer of submarine cables. It is also heat stabilizer of PE in plastics industry.
Packing: In 25kgs bag.
Storage: Store in a cool, well-ventilated place. Validity is 1 year.
