US Plast multiwall polypropylene is a rigid, lightweight, waterproof honeycomb sheet with high impact and chemical resistance. It is available in thicknesses ranging from 2 to 10 mm, with UV protection and in nine colors, and is a durable alternative to cardboard and wood for packaging, displays, and signage.
What is multiwall polypropylene?
It is a twin-wall polypropylene sheet: two layers joined by internal ribs that provide rigidity while keeping the weight very low, ranging from 450 to 2,100 g/m² depending on the gauge. Unlike corrugated signage sheet, it is used in parts that require rigidity, chemical resistance, and a long service life.

- Temperature: Vicat softening point of 154 °F / 68 °C (ISO 306) and heat deflection temperature of 185 °F / 85 °C.
- UV Protection and a thickness tolerance of ±0.15 mm.
- Flame-retardant version Class V0, available upon request.
- Recyclable, with a density of 905 kg/m³ (ASTM D1505).
