Abstract:
Thermoplastic elastormers of plastics
natural rubber (TPNR) are generally produced by blending plastics with natural rubber (in bale form) using traditional banbury type internal mixers
plastics extruders. This involves high energy consumption
also high capital costs of both rubber
plastics processing machinery. The production of Thermoplastic elastomers on a continuous basis using extruder blenders has been less applicaple to TPNR blends because natural rubber is not readily or widely available in the required granular form in natural rubber consuming countries. The manufacture of different types of granular rubber in our laboratories has not only made possible the blending of thermoplastics with natural rubber on a continuous basis but also paved the way for producing TPNR blends with improved properties. In this publication the production of different types of granular rubber, the processing characteristics of various compositions of polypropylene
natural rubber blends
the end product performance of these blends
the end product performance of these blends at different temperatures are discussed.
