I. Product Material & Construction
1. Outer Material: The outer layer of the Kiluiu Ice Neck Cooler is crafted from TPU (Thermoplastic Polyurethane Elastomer). TPU is resistant to oil, water, and mold, while also offering excellent elasticity and abrasion resistance. This ensures that the neck cooler is both comfortable and durable during use.
2. Inner Filling: The inner filling consists of phase change materials (PCMs), which are safe and eco-friendly. These materials undergo a phase change at specific temperatures, absorbing or releasing heat in the process. Below a certain temperature (beginning to solidify in environments below 18°C or 64°F), they solidify and melt during wear, absorbing heat and providing a refreshing sensation for the neck.
3. Structural Design: The neck cooler adopts a circular design that conforms to the curvature of the neck. Its appropriate elasticity ensures it fits necks of different sizes, providing both coolness and comfort during wear. Additionally, it effectively prevents the cooler from slipping or shifting, maximizing its cooling effect.
II. Cooling Effect & Duration
1. Cooling Effect: After being frozen, the neck cooler continuously releases coldness, providing a lasting refreshing sensation for the neck. Its cooling effect is typically superior to traditional ice packs due to the PCMs' ability to continuously absorb heat as they melt.
2. Duration: The duration of the cooling effect depends on various factors, such as ambient temperature, body temperature, and the material and filling of the neck cooler. Generally, in temperatures ranging from 25°C to 40°C, the neck cooler can maintain a cooling sensation for several hours. However, specific durations may vary by product.
III. Usage Instructions & Precautions
1. Usage Instructions: Before use, place the neck cooler in the freezer or refrigerator until it reaches a solid state. Then, remove and wear it around the neck. During wear, adjust the position and tightness of the neck cooler as needed.
2. Precautions:
o After use, clean and dry the neck cooler promptly to prevent bacteria growth.
o Do not heat the neck cooler in hot water or expose it to direct sunlight, as this may damage the material and affect its cooling effect.
IV. Maintenance & Care
1. Cleaning: Over time, the neck cooler may accumulate sweat and dirt, necessitating regular cleaning. When cleaning, use a mild detergent and a soft brush, avoiding bleach or strong acids and bases.
2. Drying & Storage: After cleaning, allow the neck cooler to air dry in a cool, well-ventilated area, avoiding direct sunlight or high-temperature drying to prevent material damage. When not in use, store the neck cooler in a dry, cool, well-ventilated place to avoid moisture and high temperatures.
V. Product Advantages & Application Scenarios
1. Product Advantages: The neck cooler boasts portability, ease of use, and reusability. Its cooling effect is long-lasting and gentle, preventing frostbite. Additionally, its fashionable appearance and variety of color options make it an essential summer fashion accessory.
2. Application Scenarios: The neck cooler is suitable for various outdoor activities and indoor environments, such as sports and fitness, outdoor travel, work and study, and family leisure. During hot summers, it provides people with a cool and comfortable experience.
