摘要： A process for preparing a waterborne dispersion of a silicone pressure sensitive adhesive base includes the use of a solventless polyorganosiloxane pellet containing a polyorganosilicate resin and a polyorganosiloxane gum. The waterborne dispersion of the silicone pressure sensitive adhesive base can be combined with a free radical initiator, and dried and cured to form a silicone pressure sensitive adhesive.

摘要： A process for producing foam particles from expanded thermoplastic elastomer involves (a) mixing a thermoplastic elastomer melt with a blowing agent in an extruder; (b) pressing the thermoplastic elastomer melt mixed with the blowing agent through a die plate into a pelletizing chamber; and (c) comminuting the thermoplastic elastomer melt pressed through the die plate into individual pellets. A liquid flows through the pelletizing chamber, and the pressure and temperature of the liquid are chosen such that the pellets are expanded to a desired degree in the liquid by the blowing agent and solidify to form foam particles. Additionally, the liquid in the pelletizing chamber contains wax which accumulates on the surface of the pellet during the cutting and expansion in the pelletizing chamber; and/or after separation from the liquid and drying of the foam particles, a wax is applied to the foam particles of expanded thermoplastic elastomer.

摘要： The invention refers to a method for producing expanded polymer pellets, which comprises the following steps: melting a polymer comprising a polyamide; adding at least one blowing agent; expanding the melt through at least one die for producing an expanded polymer; and pelletizing the expanded polymer. The invention further concerns polymer pellets produced with the method as well as their use, e.g. for the production of cushioning elements for sports apparel, such as for producing soles or parts of soles of sports shoes. A further aspect of the invention concerns a method for the manufacture of molded components, comprising loading pellets of an expanded to polymer material into a mold, and connecting the pellets by providing heat energy, wherein the expanded polymer material of the pellets or beads comprises a chain extender. The molded components may be used in broad ranges of application.
