The invention relates to a process for production of expanded thermoplastic elastomer, said process comprising the steps of:

Process for production of expanded thermoplastic elastomer

The invention relates to a process for production of expanded pellets from a polymer melt comprising a blowing agent, said process comprising the steps of:

Method for producing expanded granules

A pipe switch having a setting system, a housing and a closure element. The housing includes an inner wall in which a feed opening and at least two discharge openings are provided. The position of the closure element is rotatably changeable relative to the discharge openings. The setting system including a control and a drive controls the closure element such that a plurality of positions of the closure element relative to the discharge openings are realized accordingly. The closure element may be in the form of a slide or a two-part element having flaps. The setting system in cooperation with the closure system provides the plurality of positions of the closure element relative to the discharge openings, in each of which the sum of the cross-sectional areas of a first and of a second discharge opening not covered by the closure element is substantially constant.

Pipe switch with metering function

The invention relates to a process for preparing a thermoplastic polyisocyanate polyaddition product based on polyisocyanate (i) and compounds which are reactive toward polyisocyanate, with or without the use of chain extenders, a first catalyst (iv) and/or auxiliaries and/or additives (v), wherein a second catalyst is initially vaporized and then applied to the polyisocyanate polyaddition product by condensation, and to the products prepared therefrom.
