  • Publication number: 20050070645
    Abstract: There is provided a composition comprising a unique polymeric compound that provides a soft, flexible product. There is also provided a unique polymeric tampon applicator that is soft and flexible. When used as a tampon applicator barrel, the barrel is more comfortable and has improved ease of insertion. The polymeric compound primarily comprises a thermoplastic resin and a block copolymer that exhibit unique load, energy and modulus of elasticity properties. The polymeric compound should also include a plasticizer and a compatibilizer/flow modifier, and may include a slip/mold release agent, an antioxidant, and even a pigment. There is also provided a method for making the polymeric compound that will be formed into a product, such as an applicator or applicator barrel in which all of the above ingredients, except for the thermoplastic resin, are combined and formed into soft pellets. The soft resin pellets are then dry blended with pellets of the thermoplastic resin.
