Henan Daye Metallurgy Casting Material Co. Ltd. supplies closed-cell perlite, a lightweight, expanded volcanic glass used as an insulating aggregate in refractory mortars, thermal boards, and casting riser systems. The material is processed to achieve a closed-cell structure that minimizes water absorption and enhances thermal resistance, with particle sizes typically ranging from 0.1 mm to 5 mm.
This perlite is manufactured by heating raw perlite ore to 850 - 1000°C, causing expansion and vitrification into hollow, glassy spheres. The closed-cell form differs from open-cell perlite by having sealed surfaces, which improve durability in wet environments and increase its effectiveness as a filler in polymer and paint matrices. It is not chemically reactive and resists degradation under prolonged thermal exposure.
Primary buyers include foundries using it as a riser coving agent, manufacturers of insulation boards for industrial furnaces, and producers of lightweight decorative panels. It is also used as a filler in rubber and enamel coatings to reduce density and improve thermal performance. Packaging is typically in 25 kg woven polypropylene bags or bulk containers. MOQ and particle size distribution must be confirmed directly with the supplier.
| Bulk density | 80 to 150 kg/m³ |
| Particle size range | 0.1 mm to 5 mm |
| Apparent density | 120 to 180 kg/m³ |
| Thermal conductivity | 0.045 to 0.065 W/m·K at 25°C |
| Moisture content | Less than 1% by weight |
| Ash content | Less than 0.5% by weight |
| Typical particle shape | Typical spherical, closed-cell structure |
| Typical expansion ratio | Typical 4 to 20 times original volume |
| Typical pH level | Typical neutral, pH 6.5 to 7.5 |
| Typical fire rating | Typical non-combustible, meets ASTM E84 Class A |

Sourcing Closed-Cell Perlite from Henan Daye Metallurgy Casting Material Co. Ltd. - China Import Guide
Before ordering, verify the particle size distribution and bulk density of the batch with a test report. Confirm that the perlite is truly closed-cell by requesting a water absorption test and thermal conductivity measurement. Do not accept material without a declaration of ash content, as high ash levels reduce insulation efficiency and may affect refractory performance.
Confirm Incoterms - FOB Qingdao or Tianjin are typical. Lead time is generally 15 to 30 days after order confirmation. Payment terms are often 30% advance, 70% against copy of bill of lading. Ask for packaging specifications including bag weight tolerance, moisture barrier integrity, and labeling requirements for customs clearance.
Perform a pre-shipment inspection for moisture content, foreign matter, and color consistency. Request a batch certificate with test results for density, particle size, and thermal conductivity. Ensure the product is labeled with the supplier’s name, batch number, and date of production. Retain a sample for future quality reference and test against incoming shipments.
