we design a unique twin screw extruder for making Biodegradable plastic granules .
The biodegradable starch granule extruder machine work successfully in America !Early of This year, Kairong machinery customized a new extruder machine special for making starch and glycerinum granules !The biodegradable plastic extruder machine output approx 100 kg/h. All biodegradable material ins
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
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
In order to obtain adequate strength and heat resistance from a nonreactive formulation, hot melt adhesives generally require some component to separate out into a dispersed but interconnected hard phase network on cooling. For adhesives based on styrene block copolymers, the hard phase consists
This article first reviews the key materials properties that are required generally for hot melt adhesives. The formulating principles and potential product possibilities available with EVA hot melt adhesives are then reviewed, and starting formulations are offered for specific applications. Key
