Import Dpt Blowing Agent — Buy in Bulk from Supplier in China

The Dpt blowing agent is a chemical foaming compound used primarily in the production of expanded plastics and rubber products. It decomposes at elevated temperatures to release nitrogen gas, creating cellular structures in polymers such as PVC, PE, and EVA. The compound is supplied as a fine powder and is activated between 170°C and 210°C, depending on formulation and accelerator use.

It is slightly soluble in water, alcohol, and chloroform, and fully soluble in acetone, dimethylformamide, and acetic acid. The product conforms to the Chinese ministerial standard HG 2-1188-78, which defines purity thresholds and decomposition profiles. Industry-standard grades typically contain 98% or higher active content, with residual moisture below 0.5%. The material is non-flammable in solid form but releases gas under thermal stress.

This blowing agent is purchased by manufacturers of foam packaging, automotive interiors, insulation panels, and footwear soles. Buyers typically require it in bulk quantities of 25kg bags or 500kg drums. Packaging is usually multi-layer kraft paper with inner polyethylene lining to prevent moisture absorption. Trade terms are not specified, but standard practice includes FOB Qingdao or CIF destination, with payment via T/T or L/C.
