ELVAX 150W AND TOTAL HIPS 4440 POLYMERS ARE SAFE AND EFFECTIVE Our device’s Elvax® 150w and Total HIPS 4440 polymers provide a safe and effective product. HISTORY: Our oral device is made of two polymers‚ Elvax® 150w and Total HIPS 4440‚ used for a variety of purposes for decades. Since developing the first synthetic fiber--nylon--from research on large molecules called polymers‚ DuPont has remained a leader the field. In addition to Elvax®‚ DuPont makes high impact polystyrene (HIPS)

consists of polyhydroxyalkanoate‚ which contain two monomers 3-hydroxybutyrate and 3-hydroxyvalerate. Bacteria growing in tanks with a carbon-based food source in which the polymer is then isolated and purified presently produce the polymer industrially. Biotechnology has been recently used to economically attempt produce the polymer using genetic engineering technique. The advantages of this process are faster growth‚ better yields‚ easier recovery‚ and production of less extra waste biomass and cheaper
