Slide 1: Smithers Rapra Latex Conference 2010 presentation and testing partners
This presentation was presented at the Smither’s Rapra Latex and Synthetic Polymer Dispersions 2010 Conference, March 24, 2010 in Amsterdam, The Netherlands, as the lecture companion to the technical paper of same name. Several independent 3rd party testing facilities helped provide test data that i
Slide 2: Protein adsorption onto aluminum hydroxide to produce Vytex NRL
Latex feedstock contains proteins and other non-rubbers including lutoids and Frey- Wyssling particles, shown in the middle water drop. The latex feedstock is introduced to a slurry of aluminum hydroxide Al(OH)3, represented by the dumbbell shape. The proteins and non-rubbers are adsorbed onto the r
Slide 3: Carotenoid adsorption yields cleaner, whiter latex
Al(OH)3 gels have been used to characterize carotenoids. Separation of carotenoids from plant extracts on Al(OH)3 loaded cellulose paper has been previously reported. This provides evidence that carotenoid pigments can be adsorbed to the surface of Al(OH)3 during the modification process resulting i
Slide 4: Protein reduction in liquid latex and cast films
The results illustrate protein levels in both liquid and cast films. The liquid Vytex NRL is an average of Malaysian and Guatemala latices compared against standard natural rubber latex from Southeast Asia. The Vytex NRL shows a greater than 98% reduction in proteins over the control in the liquid p
Slide 5: Vytex NRL applications and appearance
Over 40,000 types of products are made from natural rubber in various forms. To date, Vytex NRL has been successfully used in every application that is currently using standard NRL. The removal of non-rubber constituents from Vytex NRL results in a very stable latex compound is whiter in appearance
Slide 6: Colloidal properties versus ISO specifications
The chart illustrates the testing results of colloidal properties for Vytex NRL HA (high ammonia) and LA (low ammonia) compared against the ISO standard specifications noted. These parameters are tested and measured for every batch of Vytex NRL HA & LA produced. Manufacturers require that the colloi
Slide 7: Foam performance characteristics
This chart depicts the key performance characteristics for foam products; density, compressive strength and indentation force deflection. The results illustrated are reported by a leading bedding manufacturer and derived from a sample of 100% natural rubber latex foam made with Vytex NRL: Apparent D
Slide 8: Protein results in medical dressing adhesives
Protein results as reported by a large medical dressing manufacturer showing a 95% reduction in proteins compared to their standard NRL. It is essential that non-dipped applications, such as cohesive bandages, use ultra low protein latex since post-leaching practices to remove proteins are not utili
Slide 9: High shear stability testing
The individual latices were placed in a high speed blender and evaluated for stability properties before and after spraying. Testing results show that the Vytex NRL, with its ultra low protein content, has exceptional high sheer stability compared to standard NRL. The stability of Vytex NRL is due t
Slide 10: Tack testing of latex samples
The tack of the latex samples was examined, using the industry standard roller ball method. Results from this test found the properties for all materials were at acceptable levels. The Vytex NRL samples have greater reproducibility and smaller errors bars than the control, demonstrating a more consi
Slide 11: Surgical glove production cycle
The flow chart depicts production cycle for a surgical glove manufacturer. Note the multiple processing stages where water and energy are utilized, particularly in the pre and post leaching and former cleaning stages. The purpose of the pre and post leaching stages is to remove the compounding chemi
Slide 12: Extractable protein comparison in gloves
The chart shows a comparison of Vytex NRL and standard NRL using the Modified Lowry (ASTM D-5712-05) test method for total extractable proteins as reported by a global surgical glove manufacturer. Results confirm that gloves made with Vytex NRL achieved low protein levels after post dipping and whil
Slide 13: ELISA antigenic protein results for surgical gloves
Depicted are the actual ELISA (ASTM 6499-07) antigenic protein test results for surgical gloves made with Vytex NRL and surgical gloves made with standard NRL produced at a major international surgical glove manufacturer’s manufacturing facility. The results reveal gloves made with Vytex NRL maintai
Slide 14: Surgical glove manufacturer savings case study
The savings case study was calculated by a surgical glove manufacturer located in India. At a production rate of 110,000 pairs per day using the data in Table 6 of technical paper, the cost savings per pair is $0.0143 or $472, 000 in an annual cost saving opportunity when using Vytex NRL compared to
Slide 15: Gel times of balloon compounds
Chart depicts the gel times of balloon compounds reported for Vytex NRL and standard NRL conducted by independent testing laboratory. Results: Vytex NRL demonstrated an average gel time of 7 seconds faster than standard NRL. A reduced gel time decrease drying temperature and time, translating into a
Slide 16: Dipping pick-up of balloons
The pick-up from the dipping process of Vytex NRL and standard NRL was assessed on the weight of the balloons made from each in independent testing. The thickness was measured using a standard thickness gauge and the weight was determined using an analytical balance. The Results: The Vytex NRL ballo
Slide 17: Helium retention of balloons
Independent testing was conducted to test our hypothesis that the removal of the non- rubbers from Vytex NRL would lead to tighter rubber particle integration, preventing the wicking loss of gas and air from within the balloon. This first chart depicts the helium retention of Vytex NRL balloons comp
Slide 18: Air retention of balloons
In same laboratory evaluation, when comparing air retention of Vytex NRL and standard NRL, balloons made with Vytex NRL maintained air retention at 60.6% on the fifth day compared to the standard NRL. 18
Slide 19: Color differences in latex films
This shows the color differences between Vytex NRL and standard NRL. When liquid latex is dried and cured, the film dries semi-transparent yellow as seen above. Whiteners such as titanium dioxide or calcium carbonate are often added to latex to express whiteness in a finished product. When viewing t
Slide 20: Pigmented balloon color comparison
These side by side pictures highlight a comparison between Vytex NRL and standard NRL in colored balloons conducted at an independent testing lab. The same amount of pigment was used for both the Vytex NRL and control NRL. Using typical industry practices, when the pigments are introduced, an oily y
Slide 21: Cost impact across the production cycle
Looking at the costs across the entire production cycle, this chart allows you to see specifically the cost impact of Vytex NRL at each process step and by product application. For example, the use of Vytex NRL can reduce the cost of compounding chemicals in gloves, foam and balloons But has no impa
Slide 22: Benefits of Vytex NRL to manufacturers
