Thermoplastic rubbers survey

SURVEY OF INDUSTRIAL BLOCK COPOLYMER THERMOPLASTIC RUBBERS... 

To conclude with, an overall picture is given in Figure 4.21 of various polymers, ranged after Tg the points for the crystalline polymers are connected by a vertical line to their melting points Tm. In this survey the nature of the various polymers is easily recognizable For rubbers Tg is far below ambient temperature T0 for amorphous thermoplastics Tg lies amply above T0. For semi-crystalline thermoplastics Tg can be below as well as above Ta in the latter case the materials have an extra resistance against higher temperature. 

A survey is made of rubber processing machinery produced by Berstorff, including compounding systems, extrader/gear pump combinations and machines for the direct extrasion of tyre components. Developments in machinery for the extrasion, coextrasion and foaming of thermoplastic elastomers are also described. BERSTORFF VMIEPE... 

Further information in particular areas can be obtained by using recent reviews. For example, readers who would like to obtain more information on the use of waste rubber in blends with thermoplastics, thermosets and virgin rubber compounds can obtain it in an extensive review that has been produced recently by Karger-Kocsis, Meszaros and Barany [1], This review also surveyed the methods available to reclaim waste rubber, the surface treatment of rubber particles to improve interfacial adhesion in blends, and the principals underlying the compatibilisation of waste rubber within the host matrix.
