Molecular formula :
CAS :
nature : When the compound extruder speed exceeds a certain limit, extrusion surface rugged, wave, bamboo, as well as the spiral distortion of the breakdown entirely random phenomenon, also called flexible Turbulence. It not only affects the quality of products, the production also affected. Its penetration is due out at high shear stress, the melt point performance by the elastic strain mixed so that the flexible extrusion materials recovery process there aberration, up and serious fracture. Impact melt fracture of the main factors in order to develop export-oriented geometry, temperature and extrusion materials own weight and molecular weight distribution. Due to lower molecular weight, molecular weight distribution broadbanding, the appropriate increase extrusion temperature, increased space-mouth, I used the loudspeaker-type or adjust the formula can be lessened or avoided melt fracture phenomenon.
