In this paper

the molecular structure

characteristics

application of elasticity and the sources of gutta¬ percha were introduced. The structure of gutta-percha mainly consists of trans 1

4-polyisoprene with order crystal softness chains. The main features of gutta-percha were of good ageing resistance

lower dynamic heat generation

higher abrasion resistance

anti-fatigue as well as memory function. The gutta percha not only comes from the extraction of natural plant such as Eucommia ulmoides Oliver but from chemical synthesis (TPI). Overview of research progress on the gutta-percha or TPI modifying plastics

asphalt and preparing the memory material were included. In the paper

we also focus on the progress of technique of blending TPI or gutta-percha with polar and nopolar rubber. The prospects of the application of gutta-percha in the industry were carried out.
