Import Cleaning Sponge — Buy in Bulk from Supplier in China

The cleaning sponge produced by Changzhou Daye Tengfei Sponge Factory is made from polyurethane foam through continuous mechanized assembly, resulting in consistent density and elasticity. Available in flat, round, and networked forms, each sponge is designed for durability under mechanical pressure and repeated use. The product has no added surfactants or abrasive particles and retains its shape after compression, with typical thickness ranging from 10mm to 30mm depending on grade.

The base material is open-cell polyurethane foam, which allows for high liquid absorption and quick drying. Standard density ranges from 18 to 30 kg/m³, with compression set values under 15% after 24 hours of load. These properties align with industrial-grade sponge standards used in automotive, electronics, and general maintenance applications. Variants include non-slip textured surfaces and laminated backing for mounting, though these are optional and not standard across all batches.

This sponge is purchased primarily by manufacturers of cleaning tools, industrial maintenance suppliers, and distributors serving automotive repair shops and food processing plants. Buyers typically order in bulk quantities of 500 to 5,000 pieces per shipment, packed in polyethylene bags with cardboard outer cartons. Lead time for standard orders is 15 to 25 days after deposit, with FOB Shanghai as the common incoterm. Custom cutting or packaging is available upon request but requires tooling confirmation.

Changzhou Daye Tengfei Sponge Factory operates from Wujin District, Changzhou, Jiangsu Province, China. The facility specializes in mechanized production of polyurethane sponge products using continuous foam lines. The supplier has no publicly listed certifications, export history, or third-party verification beyond its business registration. Response rate and average reply time are not tracked on the platform, indicating limited buyer engagement capability.

The company does not claim to serve international brands or hold quality certifications such as ISO. Its production focus appears limited to bulk sponge forms for downstream manufacturers rather than branded consumer products. No information is provided about workforce size, revenue, or client list. Buyers should request samples and verify material consistency before placing bulk orders.
