Vystar® Corporation Covers the MarketVytex Production 4
New Standard of LatexVytex® NRL Meets the New ASTM D1076-10 Category 5 Standard“Centrifuged Hevea natural latex treated with aluminum hydroxide or by other means, preserved with ammonia……containing less than 0.5 % non-rubber content.” Categories 1–4 Max. 2.0%
Vytex® NRL Advancements: Specialty GlovesClean Room and Specialty Gloves Clean room gloves made with Vytex® require ~ 50% less leaching to remove non-rubbers and chemical particles • Lower product rejection rates due to extensive alkaline washes • Decreased energy, water and waste usage Vytex® use with common antimicrobials is superior to NRL- will not react and de-stabilize

Vytex® NRL Advancements: Condoms Naturally whiter, more translucent condoms Condoms made with Vytex® NRL contained 35% fewer nitrosamines than traditional latex* Significantly reduced odor compared to NRL US FDA protein claim “less than 2 µg/dm2 antigenic protein”* Customer Test Data
Vytex® NRL Advancements: BalloonsVytex® Control Whiter, cleaner balloons for brighter, truer colors with less pigment usage Reduced usage of pigments and whiteners (TiO2) Better air and helium retention in balloons Vytex® Control

How Vytex® NRL is Helping to Solve Customer Product Development Challenges:Adhesives for Personal Care Products Goal: Safe and effective skin adhesive which can be easily and safely removed Result: Material with excellent adhesive quality Low levels of protein Adhesive can easily be removed with soap
Vytex® NRL Advancements: Foam ProductsVirtually Odor Free Significantly reduced leaching No fragrances required to mask or eliminate odor Vytex® process eliminates microbial food sources that break down to cause odor and accelerated agingWhiter, Cleaner Foams
How Vytex® NRL is Helping to Solve Customer Product Development Challenges:Customized Foams Goal: a greener, naturally based foam with slow recovery properties 4.00% 3.50% 3.00% 2.50% Typical NRL** 2.00% Vytex NRL* 1.50% Typical Polyurethane** 1.00% 0.50% 0.00% compression set * Internal test results **Carey, R.H. and Rogers, E.A.

How Vytex® NRL is Helping to Solve Customer Product Development Challenges:Specialty Fabrics for Personal Protection Products Goal: • Latex based apparel that can worn daily • Fabric must retain fluids to prevent leakage • Fabric must be easy to don and comfortable to wear • Production process does not include a leaching step Result: • Low levels of antigenic proteins • Tight film structure minimizes leakage • Low modulus material for easy donning
Opportunities for Further Enhancements to Vytex® NRLNo Ammonia AlternativeAmmonia Preserved CL 60 is the Industry Standard• Current low ammonia levels to 0.20 – 0.35%• However, TMTD used as a preservative and therefore CL60 is not Nitrosamine-freeGrowing demand for improved lattices:• Low VOCs for use in enclosed factory spaces• Specialty end use applications such as body paints, adhesives, etc.• Without ammonia or TMTD used at any stage of preservationVery Low Ammonia Vytex NRLO5 (<.05% ammonia) currently available
ConclusionsVytex® NRL Multi-patented Process Physically removes non-rubbers, including proteins, from liquid natural latex Meets new Category 5 standards of ASTM D1076-10
ConclusionsProducts Made with Vytex® NRL Exam gloves and condoms: FDA 510(k) allowances of protein claims Foams: naturally whiter with minimal latex odor Balloons: truer colors and better air/helium retention Dipped goods: less leaching/improved environmental impact Vystar R&D focuses on addressing our customers’ varied product and production challenges
