China PE Perfume Sticks - Long-Lasting Fragrance Solution from Trusted Suppliers and Factory
Product Introduction
PE Perfume Sticks, also known as PE Aromatherapy Sticks, PE Scent-Absorbing Discs, or PE Solid Fragrance Balm, are porous scent-absorbing, scent-conducting, and vaporizing rods primarily made from ultra-high molecular weight polyethylene (PE/UHMWPE). Through a specialized sintering process, it forms an internal microporous structure. These pores effectively adsorb and lock in fragrance liquids, essential oils, or medicinal solutions. Its vast specific surface area then enables slow, stable, and prolonged vapor release. Essentially, it serves as an efficient and eco-friendly vaporization medium, widely used in scenarios requiring sustained fragrance diffusion.

Product Structural Features
The core of PE perfume sticks lies in their internal structure:
- Microporous Architecture: A three-dimensional interconnected microporous structure formed by semi-melt sintering of ultra-high molecular weight PE particles. Pore sizes between particles typically range from 0.5μm to 1.0μm, with a porosity of approximately 50%. This structure provides the physical foundation for its efficient adsorption and controlled release capabilities.
- Amphiphilic Properties: Through modification, high-performance PE fragrance sticks exhibit both hydrophilic and lipophilic (amphiphilic) characteristics. This enables simultaneous adsorption of essential oil components (lipophilic) and alcohol/water (hydrophilic) in perfumes, making them suitable for water-based, oil-based, and oil-water blend fragrance liquids and essential oils, broadening their application range.
- Shape Diversity: The product can be sintered into various shapes using molds, such as cylindrical rods, sheets, or cones, to accommodate different fragrance containers and design requirements.
Its working principle is as follows: The base of the rod is immersed in the fragrance liquid. Through capillary action (wicking), the liquid is drawn up throughout the rod and gradually transported to the top exposed to air, enabling continuous and uniform evaporation.
Core Product Advantages
PE fragrance sticks offer significant advantages over traditional evaporation media (e.g., standard fiber sticks, sponges, reeds):
- Efficient liquid absorption and stable controlled release: Exceptionally high water absorption capacity with large storage volume. Maintains consistent evaporation rate to prevent sudden fragrance bursts followed by rapid fading, ensuring longer-lasting scent retention.
- Superior Physical and Chemical Stability: Resistant to high temperatures and corrosion, maintaining consistent performance in daily fragrance use. Non-water-soluble and non-clogging, it won't disintegrate or block devices during operation.
- Safe and Eco-Friendly Material: Non-toxic and odorless, this green product is safe for both humans and the environment, suitable for use in cars, homes, and various spaces.
- Durable and low-maintenance: Strong and resilient, resistant to tearing and stretching for long-lasting use. Special sintered PE rods feature self-cleaning properties, preventing bacterial growth and mold. They harden when dry to inhibit bacteria, yet soften quickly upon contact with water to restore functionality, enabling reuse.
- Wide Compatibility: Thanks to its amphiphilic properties (specific models), it works with various types of perfumes, essential oils, medicinal solutions, and other water-soluble agents, offering broad applicability.
- Economical and Eco-Friendly: Its slow evaporation rate helps conserve fragrance liquids, saving up to 40% more perfume compared to similar products.
Primary Applications
PE perfume sticks find extensive use across multiple sectors, including:
- Automotive Fragrance Systems: The most common application, such as air vent fragrance strips, solid perfume refills, and evaporator cores for car perfume holders.
- Home & Space Fragrancing: Used in flameless diffusers, aroma machines, fragrance diffusers, air purifiers, and home air fresheners to enhance indoor air quality.
- Personal Care & Beauty: Incorporated into scented candles and certain personal care products to provide aromatic ambiance.
- Humidifiers and Air Purifiers: Used as water-absorbing cotton sticks or evaporation cores in humidifiers for micro-absorption and diffusion.
- Industrial and Special Applications: Employed in liquid electric mosquito repellents for heating and evaporation, as carriers for mosquito repellent evaporation, and even in specific fields requiring controlled-release liquid formulations.
Customization Services
Many manufacturers offer flexible customization services to meet diverse client needs, primarily including:
- Dimensions and Shapes: Diameter, length, thickness, and special shapes (e.g., square, rectangular, conical, irregular) can be customized per client specifications.
- Fragrance: Multiple standard scents available (e.g., ocean, cologne, lemon, osmanthus, jasmine, lavender), with custom fragrance development supported.
- Color and Packaging: Select colors available for customization. Packaging methods (e.g., individual OPP pouches) and brand labeling can be tailored to client specifications.
- Material and Performance: Parameters like density and hardness can be adjusted within specified ranges to suit diverse application needs.
With their stable performance, eco-friendly properties, and high customizability, PE fragrance sticks have become an indispensable core component in modern aromatherapy products. Whether you are an end-user seeking products or a business considering procurement or distribution, we hope this detailed introduction proves helpful.

Frequently Asked Questions (FAQ)
1. What materials are PE Perfume Sticks made of?
PE Perfume Sticks are primarily made from ultra-high molecular weight polyethylene (PE/UHMWPE). They undergo a specialized sintering process to create a stable, internal microporous structure ideal for controlled scent absorption and vaporization.
2. How do PE Aromatherapy Sticks release fragrance?
They work through capillary action (wicking). The base of the stick absorbs the fragrance liquid, which is then drawn up through the internal microporous structure and transported to the exposed top section to evaporate continuously and uniformly into the air.
3. What shapes and sizes can be customized?
PE sticks are highly customizable. They can be produced in diameters from 1mm to 80mm and lengths from 3mm to 1000mm. Available shapes include cylindrical, sheet-like, conical, tapered, and double-ended tapered designs.
4. Are PE fragrance sticks compatible with water-based perfumes?
Yes. High-performance PE fragrance sticks can be modified to exhibit amphiphilic (both hydrophilic and lipophilic) properties. This allows them to absorb and diffuse water-based, oil-based, and oil-water blend fragrance liquids effectively.
5. What are the advantages of PE sticks over traditional fiber or reed sticks?
PE sticks offer more stable, controlled release and do not clog or disintegrate. They are highly resistant to corrosion and high temperatures, feature self-cleaning properties that inhibit mold/bacterial growth when dry, and can save up to 40% more perfume compared to traditional media.
6. What fragrance options are available for pre-scented PE sticks?
Pre-scented options include Cologne, Lemon, Ocean, Osmanthus, Lavender, Jasmine, Green Tea, Olive, and Sweet Orange. Custom scent development is also supported to meet specific requirements.
