Rubber and plastic compounding system using mixing machinery to mix polymers in the molten state (plastic), in essence, a typical melt blending process.
A, melt mixing, also known as high-temperature mixing, is the most common method of rubber-plastic mixing process. Its basic principle is that the mixing should be carried out at high temperatures in the molten state of the plastic, its typical operation process is that the first plastic at the melting temperature in the opening roller (or refiner, etc.) on the melt plasticisation, and then at a slightly lower temperature (such as 90 ℃ or so) to join the rubber mixing, or at the appropriate temperature of the rubber and plastic at the same time direct mixing, homogeneous under the film, cooling, and finally add the matching agent mixing at room temperature. B. Two-stage mixing method

B. Two-stage mixing method
B. Two-stage mixing method is also known as two-stage mixing method or masterbatch mixing method. The basic process of this method is the first two-phase polymer mixing components according to the appropriate ratio of mixing to produce two are continuous phase of the masterbatch, and then add rubber in the masterbatch for dilution, with the required ratio. Two-stage mixing method is conducive to improve the polymer dispersion.
