Foam

Henan Derun New Material Technology Co., Ltd supplies melamine foam, commonly known as a magic eraser, in a range of colours including gray, white, pink and custom shades. The foam has a measured density of 8.5-10 kg/m³ and is produced in standard block dimensions such as 100 × 70 × 30 mm, 120 × 60 × 20 mm, 100 × 100 × 50 mm, 2500 × 700 × 200 mm and 2500 × 1200 × 350 mm, with further size‑to‑order options available. Each batch carries an SGS‑issued RoHS certificate confirming the absence of hazardous substances. The material is classified as an eco‑friendly, open‑cell sponge suitable for a variety of industrial uses.

In the acoustic market, melamine foam is valued for its high sound‑absorption coefficient, typically around 0.85 across mid‑frequency bands, making it a common choice for wall and ceiling panels. Cleaning applications rely on the foam’s abrasive micro‑structure, which removes stains without chemical agents, a property shared by most commercial melamine sponges. The density range offered aligns with standard industry grades, where 8‑10 kg/m³ is regarded as the medium‑density class suitable for both acoustic and cleaning functions.

Construction contractors and acoustic consultants purchase the product for sound‑absorbing installations, while household‑goods manufacturers and automotive detailing firms use it for surface cleaning and oil removal in paint workshops. The supplier lists several packaging formats - bulk PP bulk packs, OPP bag with carton, and PVC box with carton - allowing buyers to select the most efficient option for their shipment volumes. Minimum order quantities are not disclosed in the listing, so interested importers should request the exact MOQ and lead‑time directly from the supplier. Payment and Incoterm preferences can be negotiated per order.
