Import China Dap Monomer — Buy in Bulk from Supplier in China

Diallyl phthalate monomer (DAP) from Shandong Huanya Chemical Co. is a colorless or slightly yellow transparent liquid with the CAS number 131-17-9, supplied in steel drums of 200 kg net weight or smaller 25 kg plastic drums. The monomer contains two acrylic groups, stable at room temperature but highly reactive under heat or with a catalyst, making it a key intermediate for thermoset plastics and pre-polymers. Its density at 20°C ranges from 1.110 to 1.114 g/cm³, with a flash point of 160°C and a boiling point above 305°C at 105 Pa, ensuring safe handling under standard conditions.

The material is slightly soluble in water but miscible with most organic solvents, which aids its use in formulations like UV-curable inks, acrylic resins, and unsaturated polyesters. Its refractive index at 20°C is 1.519, and its viscosity measures 8.5 mPa.s at the same temperature, providing consistent flow properties for industrial applications. The thermal expansion coefficient between 20°C and 40°C is 7.6×10⁻³/°C, a standard value for monomers used in high-temperature processes.

Industries such as electrical connectors, switches, and insulation rely on DAP monomer for its crosslinking properties, while sectors like hot stamping foil, grindstones, and dispersants utilise its stability and reactivity. Buyers typically source this monomer for applications requiring thermoset resilience, chemical resistance, or as a crosslinker in composite materials. Confirm packaging preferences and bulk requirements directly with Shandong Huanya Chemical Co., as the supplier offers flexibility in drum sizes and logistics arrangements.

Shandong Huanya Chemical Co. is based in Taierzhuang Industrial Zone, Zaozhuang, Shandong Province, China, with a postal code of 277400. The company specialises in the production and supply of diallyl phthalate monomer, positioning itself as a dedicated manufacturer of this chemical. Its profile confirms a focus on DAP monomer, with no additional product lines or diversified offerings stated in the available data.

The supplier’s trust tier is categorised as harbor, and while the response rate and average response hours are currently listed as zero, this may reflect a temporary data gap rather than a permanent condition. Buyers should verify current communication responsiveness directly with the company. The address and industrial zone location suggest access to logistics infrastructure typical for chemical suppliers in Shandong, a major hub for petrochemical production in China.
