●The oil temperature controlled screw extrusion system is adopted to dynamically control the friction heat energy distribution, solve the problems of local overheating and energy waste at the same time, and finally achieve a breakthrough improvement in production efficiency.
●Uniform micropores are formed through the (MDO) stretching process to accurately control the oxygen permeability (for example, the heating pad needs TR600 air permeability to avoid burns or insufficient heating).
●The production speed is up to 200m/min, and the annual production capacity exceeds 10,000 tons, which significantly improves the efficiency of large-scale industrial production.
