Description

1. Application Field

Fragrance polymers are widely utilized in industries where controlled and long-lasting aroma delivery is required. They play a critical role in encapsulating aromatic oils and ensuring their gradual release over time.

Key Application Areas:

Air Fresheners (solid, gel, spray formats)
Cosmetics & Personal Care (perfumed lotions, creams)
Textile Finishing (fragrance-treated fabrics)
Home Care Products (detergents, softeners, cleaning agents)
Scented Plastics & Resins (stationery, toys, packaging)
Automotive Interiors (dashboard materials, seat fabrics)
Medical & Hygiene Products (mask fresheners, feminine care)

Below is a comprehensive technical specification for our high-grade fragrance polymer, ideal for encapsulation and controlled release systems:

Method of Use

Processing Guidelines:

Fragrance Loading: Fragrance oils can be blended at a 10–30% weight ratio depending on release time required.
Mixing Speed: For dry blends, use low-speed mixers. For melt-processing, maintain moderate shear conditions.
Dispersion: Ensure even distribution of fragrance throughout the matrix.
Forming: Can be molded, extruded, or incorporated into base polymers (e.g., PP, PE, EVA).

Release Control Parameters:

Release Control Method	Description
Polymer Matrix Type	Affects release rate (amorphous vs semi-crystalline)
Particle Size	Smaller sizes release faster
Additive Level (Plasticizers)	Influences flexibility and release dynamics
Coating Layer (optional)	Adds barrier for extended release

Advanced Performance Attributes

Microencapsulation Technology

Fragrance polymers often use microencapsulation to trap scent molecules within microscopic polymer shells. This technique offers:

Extended shelf-life of fragrance
Protection against oxidation and evaporation
Triggered release (by temperature, pressure, or moisture)
Enhanced fragrance perception and strength

Microcapsule Type	Key Feature	Use Case
Melamine Formaldehyde	High-strength shell	Fabric softeners, Detergents
Urea Formaldehyde	Cost-effective encapsulation	Air fresheners, Scent beads
Gelatin-Gum Arabic	Biodegradable shells	Natural cosmetics, hygiene

Slow-Release Mechanisms

Fragrance polymers are designed for precision release control, influenced by:

Polymer matrix permeability
External environment (humidity, heat, friction)
Fragrance oil volatility
Crosslink density of polymer structure

Environment	Typical Release Duration
Low humidity (indoor use)	60–90 days
High humidity (bathroom)	30–45 days
Heated air (car vent)	15–30 days

Thermal & Chemical Resistance

These polymers are made to withstand demanding conditions:

Thermal Stability: Up to 200°C (ideal for plastic molding)
Solvent Resistance: Stable against alcohols, glycols
UV Resistance: Maintains integrity in exposed conditions

Optional grades are available with anti-yellowing agents, stabilizers, and anti-static properties.
