IIK Materials

IIK Materials has developed a novel nanocomposite material that provides superior sound absorption across a wider pressure range than conventional rubber solutions. The material is durable, flame-retardant, antifungal, low-toxicity, recyclable, and cost-effective to manufacture locally. Applications include submarines, naval vessels, commercial shipbuilding, defence equipment and fire-safe construction materials.

Defence and marine operators face increasing pressure to reduce underwater noise, improve vessel stealth, and meet emerging environmental standards. Existing rubber-based acoustic materials degrade under high-pressure conditions, reducing performance and increasing maintenance costs. Fire-safe materials often require trade-offs between performance, durability, sustainability and affordability.

Defence agencies, naval procurement organisations, submarine programs, shipbuilders and manufacturers requiring advanced acoustic insulation and fire-safe materials.

• Provisional patent filed through UNSW
• Independent testing shows 33% better sound absorption than leading rubber alternatives
• Early engagement with DSTG, H&B Defence, and Boeing validates defence and aerospace market interest. LinkedIn: Imrana Kabir
