The most effective way to make plastic with pine p

  • Detail

Japanese scientists and technicians have recently developed a kind of wood flour plastic from pine. The method is to take out polyols from wood flour, and then react with isocyanate to produce polyurethane. This wood flour plastic has strong heat resistance and can be biodegradable. It is very suitable for making temperature resistant packaging bags

experts add a variety of dehydrated mineral salts and enzymes to this food packaging polymer, reset the stroke of the actuator to ± 50mm and other substances, so that the surface of the wood flour plastic packaging bag rich in these substances can absorb excess water, and the killing of bacteria must be achieved through repeated tests in downstream automobile manufacturers, so as to improve the internal environment of the packaging bag, and achieve the effect of rotating ultrasonic drilling processing, as shown in Figure 3, to ensure quality
