ADC foaming agent is the most economical and widely used organic chemical foaming agent for all industrial foaming agents. Foaming principle is through the temperature, so that at a certain temperature decomposition of a large number of gases generated in the molten polyolefin matrix expansion of bubbles, the formation of closed-cell foam structure. The foaming agent is suitable for different processing techniques, including extrusion, injection molding, moulding foaming, etc. Welcome customers to order our Rubber foam ring, foam rings for crafts, foam ring buoy, styrofoam ring.
