Gypsum Aroma Diffuser Slice

1. Product Overview

1.1 Stable Gypsum Composite Material Composition

The gypsum aroma diffuser slice adopts high-purity gypsum powder as the main raw material, mixed with functional filler and eco-friendly binder, and is formed by room-temperature casting to build a uniform porous gypsum matrix. The optimized material formula balances structural strength and oil absorption capacity. The Mohs hardness reaches 2.0–2.5, which avoids the fragile defect of ordinary gypsum products. The material has low shrinkage after molding, supporting clear embossed logo and pattern engraving on the surface, meeting customized branding requirements while retaining excellent essential oil adsorption performance.

1.2 Controllable Porosity & Stable Fragrance Release

With optimized casting formula, the gypsum diffuser slice forms interconnected micropores inside. The total porosity is 35%–42% and open porosity is 28%–35%. The pore size ranges from 2–12 μm. The natural capillary structure can steadily absorb and lock essential oils, preventing oil overflow and surface flooding. Different from products with single rapid volatilization, this pore structure achieves slow and even fragrance release, delivering stable aroma within the 10–15 ㎡ diffusion range, avoiding sudden strong scent or fast fragrance depletion.

1.3 Reliable Environmental Adaptability

The gypsum aroma slice maintains stable physical properties within the working temperature range of -5℃ ~ 60℃. It features low thermal expansion, no deformation or cracking under normal indoor and vehicle temperature fluctuations. The product moisture content is controlled ≤ 3%, which effectively reduces the risk of mildew and deformation in common humid environments. It has good compatibility with most plant essential oils and synthetic fragrances, no chemical reaction occurs, preventing odor mutation and pore blockage during long-term use.

1.4 Safe & Lightweight Material Features

Made of inorganic gypsum raw materials, the finished diffuser slice is non-toxic, odorless and pollution-free. No formaldehyde or volatile harmful substances will be released during fragrance volatilization. The product density is 1.8–2.0 g/cm³, lightweight with solid texture. Unlike organic diffuser materials prone to mildew, it will not breed bacteria easily, providing safe aromatherapy experience for families, children and pets. The surface precision can reach 0.3 mm, supporting delicate pattern and logo customization.

1.5 Practical & Cost-Effective Performance

The cast-molded gypsum slice has good machinability and surface carving performance. After long-term use, when residual oil sediment reduces the fragrance diffusion effect, it can be cleaned with warm water and air-dried to restore partial oil absorption capacity. Compared with disposable diffuser sticks, it extends service life and cuts accessory replacement cost. The integrated molding process ensures consistent batch quality, stable dimension and uniform aroma performance for each piece.

2. Core Application Scenarios

2.1 Household Indoor Aromatherapy

Perfect for living rooms, bedrooms, cloakrooms, bathrooms and study rooms. With a fragrance diffusion coverage of 10–15㎡, it continuously releases mild aroma to mask toilet odor, wardrobe musty smell and kitchen residual odor, creating a comfortable layered fragrance atmosphere. Safe inorganic material is suitable for closed indoor spaces. It matches lavender, citrus, sandalwood and other essential oils, satisfying diverse home fragrance needs. Embossed surface also works as decorative tabletop ornament.

2.2 Vehicle Aroma Decoration

Suitable for car diffuser accessories and automotive interior decoration. It can work stably under normal in-car temperature variation. The solid structure resists minor vibration during driving. It removes leather smell and air-conditioning peculiar smell inside the car. Customizable shapes and engraved logos are available to match various car fragrance holders, combining aroma diffusion and decorative functions.

2.3 Commercial Space Fragrance & Gift Customization

Applicable for fragrance layout in offices, clothing stores, hotels and beauty salons. It supports custom embossed patterns and brand logos, widely used for high-end corporate gifts, holiday presents and DIY aromatherapy crafts. The delicate gypsum texture improves product grade. Customers can match different essential oils to create exclusive fragrance gifts, with both ornamental value and practical aroma function.

3. Product Process & Structural Advantages

3.1 Room Temperature Casting Molding Process

The gypsum aroma slice adopts room-temperature casting molding technology. After raw material mixing, mold pouring, curing and surface finishing, the finished product forms an integrated solid structure. It avoids assembly gaps. The micropores are evenly distributed inside the substrate. Mature casting technology enables flexible customization of shapes, sizes and surface embossment. Batch stability is guaranteed with consistent oil absorption and fragrance release performance.

3.2 Natural Capillary Fragrance Volatilization Principle

Relying on natural capillary adsorption of porous gypsum, essential oil is absorbed and stored in interconnected micropores, then diffuses outward slowly and evenly. It does not produce sharp strong scent at the beginning of use. The volatilization speed keeps stable as essential oil consumes. It maintains lasting soft aroma, bringing comfortable long-time aromatherapy experience.

4. Usage and Maintenance Precautions

Handle gently during transportation to avoid heavy impact and breakage. Do not soak the product in strong corrosive solvent for a long time to prevent pore contamination. Although the product can work at -5~60℃, avoid long-time exposure to direct intense heat.

When fragrance becomes weak after long-term use due to residual essential oil deposits, clean it with warm water, then place it in ventilated place for natural drying. Do not heat bake. After drying, the oil absorption and fragrance diffusion performance can be partially restored for cyclic use.
