摘要：
A method of continuous manufacturing of a foaming particle composition at a high gas pressure, the method comprising: Adding a particle in a pre-pressurization zone and increasing the gas pressure to 137.9 to 21.373.7 kPa (20 to 3100 psi) to form an effective pressurized particle to create one of the passages, cracks or pores, and a mixture thereof, in the particle； Transfer the pressurized particle to a heating zone separate from the pre-pressurization zone, where the heating zone operates at a gas pressure of 137.9 to 21,373.7 kPa (20 to 3100 psi), and continuously displace the pressurized particle along the heating zone at a speed and for an effective time to increase the temperature of the pressurized particle above its glass transition temperature to form a heated particle； Perform a continuous transition of the heated particle from the heating zone through a transition zone operating at a gas pressure of 137.9 to 21,373.7 kPa (20 to 3100 psi)； Transfer the heated particle from the transition zone to a cooling zone, separated from the heating zone and the transition zone, operating the cooling zone at a gas pressure of 137.9 to 21.373.7 kPa (20 to 3100 psi), and continuously moving the heated particle through the cooling zone at a speed and for an effective time to lower the temperature of the heated particle below its glass transition temperature to form a cooled particle； Move the cooled particle to a depressurization zone separated from the cooling zone to lower the gas pressure from 137.9 to 21,373.7 kPa (20 to 3100 psi) to ambient pressure to form a depressurized and cooled particle； and Release the depressurized and cooled particle from the depressurization zone to form the foaming particle composition with pressurized gas remaining trapped therein.Un método de fabricación continua de una composición de partícula espumante a una presión de gas alta, comprendiendo el método: Añadir una partícula en una zona de presurización previa y aumentar la presión de
