2. What is Vytex® Natural Rubber Latex?
A fully commercialized source material, using a multi-patented
process and green chemistry to significantly reduce non-rubber
components, including antigenic proteins, for a more
consistent, stable and cleaner natural rubber latex

5. New Standard of Latex
Vytex® 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.”

6. Vytex® NRL Advancements: Specialty Gloves
Clean 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

8. 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

9. Vytex® NRL Advancements: Balloons
Vytex® 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

11. Vytex® NRL Advancements: Adhesives
Spray Adhesives
 Less non-rubber debris for cleaner spray
 Absence of non-rubber debris reduces spray-head clogging;
decreased equipment/line downtime
 Cleaner adhesives flow easily; allowing for gravity-fed system
vs. pump system using propellants
 ~ 40% faster tack time in some formulations compared to
traditional latex

13. 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

14. Vytex® NRL Advancements: Foam Products
Virtually 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 aging
Whiter, Cleaner Foams

18. 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

19. Opportunities for Further Enhancements to Vytex® NRL
No Ammonia Alternative
Ammonia 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-free
Growing 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 preservation
Very Low Ammonia Vytex NRLO5 (<.05% ammonia) currently available

20. Conclusions
Vytex® NRL Multi-patented Process
 Physically removes non-rubbers, including proteins,
from liquid natural latex
 Meets new Category 5 standards of ASTM D1076-10

21. Conclusions
Products 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
