Method and device for producing extrusions from ultra-high molecular polyethylene |
摘要 |
For producing extrudates, such as profiles or granules, pulverulent or small-particulate ultrahigh molecular weight polyethylene is processed on single-screw extruders. By using a screw with specific geometry, the thermal degradation of the polymer to form low molecular weight products is avoided. Furthermore, profiles are obtained which have a flawless surface, are free of voids and pores and have no internal stresses. <IMAGE> |
