Evonik licenses new technology for ultrathin diaper designs

  • Innovative absorbent core technology eliminates fluff pulp and makes diapers even thinner
  • Considerable improvement of absorption performance
  • Costs of raw materials, transportation, and processing are significantly reduced when using the technology

Essen. Evonik, one of the world’s leading suppliers of superabsorbent polymers, intends to offer an innovative absorbent core technology for ultrathin diapers. Here, the superabsorbent particles are found in small pockets that are formed by laminated nonwovens which allow the diaper core to absorb fluid even faster and distribute it. Evonik is planning to sell the technology on the market in a licensing procedure. The technology has already been described in various patent filings, for example WO2012146748, inventor: W. Fenske et al.

The new technology gives the diaper core a particularly high level of stability, ensuring that the superabsorbent particles always remain at the place where they are needed. This special design, combined with an enhanced FAVOR® superabsorbent polymer, enables the diaper to be used more efficiently: Rewetting is significantly reduced, while wearing comfort is enhanced considerably.

Evonik sees considerable potential in further advancing this technology that follows the trend to ultrathin underwear-like diapers. The users of the technology also benefit from lower raw material and logistic costs. This novel absorbent core technology matches Evonik’s mission as a leading solution provider for the hygiene industry.

Superabsorbent polymers, the key raw material of modern hygiene articles, are water-insoluble, cross-linked polymers. They are capable of absorbing and storing up to 500 times their own weight in aqueous liquids, while also providing other performance characteristics such as skin dryness. The scope of applications for Evonik’s superabsorbent polymers reaches beyond baby diapers and also includes feminine hygiene and adult incontinence products as well as a broad range of technical areas.

Evonik is a world-leading supplier of superabsorbent polymers with manufacturing plants in the United States, Germany, and Saudi Arabia.
