A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99% weight of the porous mass, and the binder particles comprises about 1-99% weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.

Polyethylene compositions for producing moldings have a surface resistance of at most 10.sup.9 .OMEGA. including

Polyethylene molding compositions

Moldings of ultra high molecular weight polyethylene powder are produced by heating the polymer powder at 160.degree. to 280.degree. C. in a mold without applying pressure or at a pressure of up to 0.5 MPa, and then cooling it to room temperature at a pressure of from 4 to 20 MPa.

Process for moulding ultra-high molecular weight polyethylene powder

For the production of extrudates such as profiles or granules, pulverulent or finely divided ultra-high molecular weight polyethylene is processed on single screw extruders. By the use of a screw with a specific geometry, thermal degradation of the polymer into low molecular weight products is avoided. Furthermore, profiles are obtained which have perfect surfaces, are free of voids and pores, and have no internal stresses.
