The present disclosure provides for a formula and process for making elastomeric rubber thin film articles. In particular, the formula and process is a system which produces non-or Guayule natural rubber latex (GNRL) thin film articles which have a thickness of 30-80 microns (0.03-0.08 mm), and preferably less than 40 microns (0.04 mm). These thin film articles exhibit physical strength properties similar to that ofnatural rubber latex (NRL). More specifically, the disclosed thin rubber thin film articles exhibit unaged tensile strength of at least 24 MPa (about 3500 psi) and aged tensile strength of at least 19 MPa (about 2800 psi).

Guayule natural rubber latex thin film articles

Disclosed is a method and apparatus for the extraction of high molecular weight biopolymers from plants. Specifically, invention described herein relates to the commercial processing of plant material, including that from desert plants native to the southwestern United States and Mexico, such as the guayule plant (), for the extraction of biopolymers, including natural rubbers. More specifically, the invention relates to laboratory to commercial scale extraction of high molecular weight biopolymers from plant materials including the chemical and mechanical processing of the plants and purification of the extracted biopolymer.
