Yulex was the first company to rethink how crude hevea rubber could be purified without the use of harsh chemicals or loss of physical performance properties. After years of research, development and testing, Yulex created the industry’s first purification and refinement process that utilized safe, clean water to strip away unwanted impurities and water-soluble proteins while improving physical performance of both latex emulsion and dry solid materials: The Yulex Pure® process was perfected at the company’s technology campus and has established the gold-standard for purity, performance and extremely low protein content, and is the only commercially available portfolio of FSC 100% certified and purified natural rubber on the market today.
Yulex’s commitment drove the technical team to develop a completely new process technique called liquid-to-liquid dilution chemistry which isolates impurities, pollutants and detaches soluble proteins from the rubber particles without damaging the molecular weight or polymer chain structure; all the while maintaining the correct alkalinity level. Once the reaction is complete, the process excludes the impurities, contaminants, and soluble proteins from the colloidal suspension without damaging the distribution of rubber particles. As excess liquid is removed from the colloidal suspension the Yulex Pure process concentrates rubber content, forming a highly concentrated latex emulsion. The Yulex Pure process improves elongation, green strength, pot-life, tear resistance, and modulus while producing a bright white, odor-free latex emulsion that enhances and improves your products.
