In the new energy, power semiconductor, and consumer electronics industries, thermal conductive silicone pads and thermal potting compounds serve as core heat-dissipation materials for devices. As the primary thermal conductive filler, alumina powder quality directly determines the end product's overall performance in heat dissipation, insulation, flexibility, and processing workability. Shandong Greatsun Aopeng's customized alumina powder, specifically engineered for thermal silicone, helps thermal management enterprises build high-performance silicone products through precise customization, stable quality, and full-chain service.

Current industry players commonly encounter numerous practical challenges: identical formulas failing to achieve designed thermal conductivity targets; poor compound flowability after high filler loading, leading to processing difficulties; struggles to balance the finished product's insulation, shock absorption, and flame-retardant performances; and imported powders facing long lead times alongside persistently high costs. Focusing on the real-world operating conditions of thermal silicone, Shandong Greatsun Aopeng integrates the entire process across powder calcination, particle size classification, and surface modification to deliver fully customized, integrated filler solutions.
Customized Solutions Tailored to Customer Positioning
We offer flexible customization based on our customers' specific product positioning:
○ General-Purpose Thermal Silicone (LED Power Supplies & Adapters): Blended powders combining 20–30 μm, 5–10 μm, and 1–3 μm particle sizes.
○ High-Power Devices (CPUs & IGBTs): High-thermal-conductivity grade products featuring a combination of large, medium, and small particles supplemented by ultrafine powder.
○ Foldable Screens & Ultra-Thin Flexible Pads: Custom coarse-particle-free fine size combinations, guaranteeing high elongation at break and superior performance under repeated bending.

Material Characteristics & Surface Modification
The products utilize high-density α-phase alumina featuring a spherical morphology, high packing density, and strictly controlled impurity and moisture levels. This ensures a continuous thermal conductivity path while maintaining the excellent insulation performance of the silicone. We also provide pre-modified powders to resolve fine particle agglomeration, improve compounding processability, and minimize bubbles and defects.
Market Validation & Green Production
Our products have been adopted in mass production by numerous domestic thermal interface material manufacturers, with our multi-modal 1 + 5 + 40/70 μm blended products gaining high recognition from customers in the South China market. Simultaneously committed to green manufacturing, Greatsun Aopeng leverages its hazardous and solid waste resource utilization sector to build high-value, cost-effective domestic fillers that reduce enterprise procurement costs while ensuring stable quality.
Comprehensive Technical Services & Future R&D
Beyond delivering powder materials, Greatsun Aopeng provides full technical support, including pre-sales grade selection, formula reference guidance, and troubleshooting services. When customers encounter issues such as off-target thermal conductivity, insufficient adhesion, or insulation fluctuations, we collaborate to analyze powder-side factors and provide optimization solutions. Looking toward future sectors like power batteries, 5G equipment, and AI hardware, we continue to iterate new products—such as nanocomposites and low oil-absorption powders—joining hands with thermal silicone enterprises to seize growth opportunities in the thermal management industry.
