Abstract:
Thermoplastic elastomers are a relatively new
class of materials which compete with thermoset rubbers in
some areas and thermoplastic materials in other areas. The
main thrust of the present investigation is a comparative
study’ on commercially .available triblock. styrene thermoplastic
elastomers and those derived from blends of
acrylonitrile-butadiene rubber and poly(vinyl chloride).
The styrene—based thermoplastic elastomers are gaining
acceptance as a replacement for both natural and synthetic
rubber‘ in many‘ applications. TPEs based on blends of
elastomers and plastics ix: the fastest growing segment of
the broad class of thermoplastic elastomers. Broad
applicability and simple technology of production are the
attractive features of this class of TPES. NBR/PVC thermoplastic
elastomers were selected for this investigation due
to the versatility of PVC, its number one position, low
cost. ability to Ina compounded into various flexible and
rigid form with good physical and chemical and weathering
properties etc., which will be passed over to PVC blends
especially NBR/PVC blends which are known to form miscible
systems
