, which is tapped from a tree grown in tropical regions of Asia.
East Timor, in the Indonesian archipelago, produced modest quantities of Hevea rubber
, grown mainly by the largest plantation company, the Sociedade Agricola Patria e Trabalho.
The American motor industry had an insatiable demand for Hevea rubber
, until synthetic substitutes emerged after 1950.
Cooper and its consortium partners, PanAridus, Arizona State University, Cornell University and the Agricultural Research Service of the United States Department of Agriculture, say that testing so far suggests tire performance that is at least equal to tires made of components derived from the Hevea rubber
C4) Effect of non-rubber constituents on guayule and Hevea rubber
Effect of Non-Rubber Constituents on Guayule and Hevea Rubber
Intrinsic Properties--Shirin Mohammad Ali Monadjemi, Ohio State University 10:45 a.
While guayule rubber has the same molecular weight and general properties as Hevea rubber
, it does not contain the proteins present in hevea rubber
that can cause severe allergic reaction (Cornish, 1996).
The causes of the meteoric rise in the prevalence of latex allergy included increased use of protective medical gloves due to universal precautions and the resultant accelerated latex production and manufacturing of hevea rubber
