Our sintered PE fragrance diffuser sheets are manufactured by high-temperature sintering of polyethylene powder, forming an interconnected, evenly distributed microporous structure. Unlike felt, paper or ceramic diffuser media, this porous PE aroma pad delivers consistent absorption and controlled, long-lasting fragrance release, making it a reliable core component for air freshener OEM and aroma diffuser assemblies.
The integrated sintered porous structure acts like a stable storage medium for essential oils, perfume and water-based fragrance liquid. Once the PE sheet absorbs the fragrance liquid, the uniform capillary pores gradually release aroma into the air at a steady rate. It avoids sudden strong bursts of scent, dripping leakage, early exhaustion or blockage, maintaining mild, balanced fragrance output for a longer service cycle.
Controlled Slow Release Performance Precision pore size design enables stable volatilization speed. No sharp strong smell at the beginning or fast fading. It keeps consistent aroma for days after one oil refill.
Excellent Chemical Compatibility Made of pure PE material with good inertness. Resistant to most essential oils, alcohol-based perfume, fragrance solvents, weak acid and weak base liquids. It will not react with fragrance formula and change the original scent.
No Fiber Shedding & High Structural Strength One-piece sintered molding, no loose fibers falling off. Shock-resistant, vibration-proof and not easy to crack, perfect for car air fresheners with bumpy road conditions.
Water-Insoluble & Reusable The sheet will not dissolve or collapse after soaking in fragrance liquid. It can be cleaned and re-infused with different scents repeatedly.
Flexible Customization We support custom shape, thickness, diameter, pore size and porosity. Round, square, annular, irregular special shapes are all available to match your diffuser housing.
Safe & Eco-Friendly Non-toxic raw material, flame-free diffusion, low risk for enclosed spaces. Suitable for household, automotive and consumer aroma products.

Q1: Can this PE fragrance sheet work with all kinds of essential oils? A1: It fits most plant essential oils, alcohol perfume and water-based fragrance. For strong corrosive solvents, please send us your liquid sample for compatibility testing.
Q2: How long will the scent last after one oil filling? A2: It depends on pore size, oil loading amount and ambient air flow. Normally, it provides steady fragrance for 2–4 weeks under regular indoor conditions.
Q3: Can I change to another scent on the same PE sheet? A3: Yes. Clean the sheet with clean solvent and fully dry it before refilling new fragrance to avoid scent cross-contamination.
Q4: What custom files do you accept for shape making? A4: We accept drawings, samples or DXF files for tooling development.
