Lightweight, flexible willtec foam excels at heat and sound insulation

pinta acoustic's proprietary willtec foam meets many stringent requirements for fire resistance, heat shielding, sound control and cushioning without compromising important characteristics such as weight, flexibility, easy installation or reasonable cost.

Withstands extreme temperatures

willtec foam is made from lightweight, porous melamine. It meets all ASTM E-84 requirements for flame spread and smoke density, and it passes the aggressive new UL 1715 room fire exposure test. This versatile foam can even be exposed to constant temperatures up to 300°F and short-term temperatures up to 482°F. It will char, but not ignite, at temperatures up to 1120°F.

Unique construction meets a range of requirements

The open-celled, fiber-free structure of willtec foam gives it an extremely low density, making it lightweight and flexible. The open cells also enhance the material's ability to dampen sound over a wide range of frequencies. In addition, willtec foam is easy to cut, mold, trim and laminate. Installation in machinery, rooms and compartments is easy with one of pinta's pressure-sensitive adhesive backings or acouSTIC caulking gun adhesive.

Handles tough environmental conditions

willtec foam comes standard in  natural white or grey colors. It can also be painted in a variety of colors. Many other surface finishes, including a Hypalon® coating specially formulated for pinta, are also available to resist wear from dirt, water, solvents and other environmental irritants. pinta offers consultation for special requirements.
