    main reasons that the twin-screw extruder affects the uniformity of the extrudate

    (1) Temperature. Temperature has a significant impact on the extrusion of plastics and the performance of the parison: it can reduce the melt viscosity, improve the melt flowability, reduce the power consumption of the extruder; it can appropriately increase the screw speed without affecting the mix

    Advances in EVA Hot Melt Adhesives

    EVA resins normally used in hot melt adhesives have a vinyl acetate content less than 40%. However, a new product line, Levamelt, from Bayer provides vinyl acetate contents in the 40-80% range. This polymer backbone consists of fully saturated methylene units with acetate groups attached. Thus it

    Formulation of EVA Hot Melt System

    The semicrystalline polymers generally exhibit a greater temperature range for application and a higher modulus at elevated temperatures as was shown in Figure 2. This is due to the pseudo-crosslinking characteristics of hydrogen bonding. Amorphous polymers would require significant molecular weig
