Characteristics:
Antioxidant 1081 is a very popular phenol antioxidant with excellent performance.it is environment-friendly,nontoxic and without coloration.
Applications
① In rubber industry: antioxidant 1018 is a very good antioxidant for PE,PP,synthetic rubber and latex.products by adding antioxidant 1081 can resist high temperature,prevent UV absorber,reduce the damage of multiple deformation and can passivate the unstable transition metal salt. These performance is more obvious in dry rubber by adding antioxidant 1081(2246-S) than by antioxidant 2246.antioxidant 1081 is environment-friendly and don’t be decolored by exposing it to the sunlight.it is mainly used in producing white sidewall of tires,other light color goods and latex goods.
② In plastic industry: antioxidant 1081 can prevent the heat-aging and light-aging of PE,PVC,polyamide,chlorinated polyether,HIPS,ABS resin,daicel,cellulosic resin etc.especially in the processing of polyamine hot melt adhesive,antioxidant is a very important choice as the main antioxidant.when it is used with phosphite ester assistant antioxidant there is a very good synergistic effect which is much better by using them alone.
③ In oil industry: antioxidant 1081 is an excellent stabilization agent for lubricant,blend diesel fuel,gas oil,engine oil,anti-wear hydraulic fluid.it can prevent these oils from heat-aging and light-aging and inhibit nitryl oxidation.because of the good synergistic effect of S and phenol antioxidant 1081 has good oil solubility.this make it easy and convenient add into these different oils.the comprehensive performance of antioxidant is much better than common kind antioxidant such as T501,L135,L115,DNA,AP-36 and especially suitable for hydrotreated base oil and lubricant.the dosage is just 1/2 of those common antioxidant such as T501.but the final effect is far better than T501.it can improve the quality and level of the finished goods easily and greatly.
① synergistic effect: sulfur-containing hindered phenol antioxidant 1081 is rarely absorbed by the carbon black but has very obvious synergistic effect as when it is used together with carbon black as they are transferred into chemical compounds with greater antioxidant efficacy under the catalysis of carbon black that enhances stability of the polymer.antioxidant 1081 also has good synergistic effect with alkyl phenol or phosphite compounds also.it works very well when used in producing high electrical property plastics.general dosage is 0.1~1 phr.
