Plasticizer A LTS-82A 86A is a mixture of high molecular weight aliphatic polymers containing unsaturated bonds and active agents. The product does not affect the physical properties of the rubber compound, and has the property of reducing the Mooney viscosity and shortening the mixing time, and the hardness of the finished product is not affected. Inorganic fillers such as carbon black and white carbon have high-performance dispersion, improve extrusion and injection properties of rubber compounds, smooth surface, and significantly reduce internal porosity. This product can reduce the heat generation of the rubber compound, reduce wear, improve tire life and reduce energy consumption.
Product performance: Good protection against ozone and flex fatigue aging. It also has good protection for general aging such as hot oxygen and harmful metals such as molybdenum and manganese. Can be used as a stabilizer for synthetic rubber.
Application description:Rubber adhesive RA produces adhesion through reaction with methylene acceptor. For example, it reacts with rubber binder RE and resorcinol formaldehyde resin GLR-20 to form thermosetting resin. The reaction will occur very quickly at vulcanization temperature. If the reaction occurs before vulcanization, the adhesion of the coordination system will be greatly reduced or even lost. Usually, the rubber, filler and methylene acceptor are prepared at high temperature, and then the rubber adhesive RA is added with accelerator and sulfur in the final refining stage. The recommended proportion is 2-5 rubber adhesive RA for each 100 rubber, and 2-5 GLR-20 resins. Packaging storage and transportation: 1. The rubber adhesive RA is wrapped in woven bags and lined with polyethylene plastic bags. The net weight is 25Kg per package. 2. Before transport and storage, check whether the product packaging is intact. During storage and transportation, the products should be stored in dry, clean and cool warehouses in order to prevent dampness and heat deterioration. 3. The effective storage period is one year.
