Soundproofing wastewater pipes based on alternative mineral fillers

Developing alternative dry-blends for better acoustic insulation, Adequa is researching the performance of different minerals. It’s studying the availability, density and cost of the materials, as well as the ease of transformation, compatibility of the resin, stability of the dry blend, toxicity and recycling aspects. The most promising materials that are compatible with PVC have been selected, with results showing improved acoustic performance of pipe systems. Trials at an industrial level are planned.
