Vystar Unveils Deproteinized Natural Rubber Latex As Platform for Sustainable Grades of Latex and Solid Rubbers at International Latex Conference


  • Creating Bioelastoplast natural rubber materials with improved performance for latex films and solid rubber dynamic applications
  • Incorporating Single Walled Carbon Nano Tubes (SWCNT) at latex stage reduces carbon black requirements for improved eco-friendliness
  • Test results confirm reduction of harmful metals and volatile emission substances

WORCESTER, Mass. and AKRON, Ohio, Aug. 08, 2019 (GLOBE NEWSWIRE) --  Vystar Corp. (OTC Market: VYST) announced advances in ultra-low protein natural rubber latex relating to performance improvements, new applications and formulations, and improved eco-friendliness at the International Latex Conference (ILC) in Akron, Ohio this week.  Ranjit K. Matthan, Ph.D., a latex and rubber science expert, a member of Vystar's Board of Directors and Vystar R&D head for Vytex® rubber latex for commercial raw materials, shared details in a presentation titled “Ultra Low Protein Natural Rubber Latex – A Platform for Sustainable Natural Rubber Intermediates, Bioelastoplastics and Products,” which will soon be available through the ILC 2019 Conference and Vystar websites.

Dr. Ranjit Matthan stated, “Through our continuing targeted research, we are capitalizing on the patented Vytex process to remove proteins and non-rubbers from rubber and latex to create environmentally friendly raw materials with improved characteristics for strength, durability, flexibility, and resilience that may be able to provide a reduced carbon footprint alternative to some synthetic fossil fuel-based polymers that are less environmentally friendly in the manufacturing and end use lifecycle.  Vystar will engage and support industry partners to customize products to their requirements.”

ADVANCES IN BIOELASTOPLASTICS - Bioelastoplastics produced from Vytex® latex with customized viscoelastic behavior (elasticity and plasticity) enable enhanced performance in a range of static and dynamic mode applications.  Vytex latex is available in high/low/no ammonia and low/no nitrosamine formulations and offers cleaner and purer latices and rubbers that enable higher performance materials as follows:  

  • Improved ultra-thin film applications enabled by Low Gel Content Latices with reduced hardening.  Vytex’s removal of the proteins and reduction of the non-rubber constituents has been found to inhibit the gel formation in latices which causes undesirable hardening akin to storage hardening in dry rubber. 
  • Cost-Effective Alternative Bioelastoplastics - Modifications of the Vytex latex prior to concentration creates cost-effective alternative bioelastoplast materials including grafted, epoxidized, depolymerized, and halogenated variants.
  • Reduce Carbon Black with nanotubes - Incorporating Single Walled Carbon Nano Tubes (SWCNT) at the latex stage allows for reducing carbon black usage for better  eco-friendliness.


  • Protein removal – now reduces the antigenic allergenic proteins to nanogram levels  --
