Product properties : It is off-white powder, non-toxic, odourless, with bitter taste. Soluble in acetone, ethanol, insoluble in benzene, gasoline, water. It is stable in storage.
Product Usage: This product is one of the non-polluting antioxidant species, similar to antioxidant MBZ in performance, used as natural rubber, styrene butadiene, butadiene rubber, nitrile rubber and other synthetic rubber, anti-heat aging effect is obvious, usually and amine, phenolic antioxidants and have a synergistic effect, to improve the performance of heat and oxygen aging, can be used for nitrile rubber. When used together with accelerator M, DM, it has the effect of inhibiting the accelerated aging of harmful metals. Usually used in transparent Rubber Products, light-coloured and bright-coloured rubber products. The effect on the vulcanisation characteristics of rubber mixing is significantly smaller than that of antioxidant MB, and it is usually not necessary to adjust the vulcanisation system due to the use of this product. It can be used as auxiliary sensitiser in natural rubber latex foaming products with uniform foam structure and better effect than MB.
Packing: 25kg plastic woven bag, paper-plastic composite bag, kraft paper bag.
Product expiry date: It should be stored in a cool, dry and well-ventilated place. Packed products should be avoided from direct sunlight, valid for 2 years.
Company information
The company's main import and export products include
(1)Intermediates：A material produced in an API process step that must undergo further molecular changes or refinement to become an API. Intermediates may or may not be separated.Our Intermediate products include pharmaceutical intermediates, pesticide intermediates and dye intermediates.
(2)Catalysts And Auxiliaries：A catalyst is generally defined as a substance that increases the rate of a reaction without changing the total standard Gibbs free energy change of the reaction. It can also be expressed as a substance that increases the rate of a chemical reaction without altering the chemical equilibrium and whose own mass and chemical properties do not change before or after the chemical reaction.Auxiliaries (auxiliaries; additives) Defined in medicine as excipients and additives used in the production of medicines and in the formulation of prescriptions, i.e., a general term for all materials other than the main active ingredient of the drug, and an important constituent of pharmaceutical preparations. Also known as additives.Our main Catalysts and Additives products include Rubber Additives、Water Treatment agent.
