Cold-color-changing vinyl adhesive material is an innovative functional material. It can change color when the temperature varies, and at the same time, it has excellent bonding performance and the flexibility of vinyl materials. This type of material combines thermochromic technology with the adhesive properties of vinyl, and is widely used in fields such as temperature indication, smart packaging, automotive decoration, and building energy conservation. The following will provide a comprehensive introduction from aspects such as product features, working principles, application scenarios, technical parameters and market prospects.
Product Introduction of Cold Color-changing Vinyl Adhesive Materials
Cold-color-changing vinyl adhesive material is an innovative functional material. It can change color when the temperature varies, and at the same time, it has excellent bonding performance and the flexibility of vinyl materials. This type of material combines thermochromic technology with the adhesive properties of vinyl, and is widely used in fields such as temperature indication, smart packaging, automotive decoration, and building energy conservation. The following will provide a comprehensive introduction from aspects such as product features, working principles, application scenarios, technical parameters and market prospects.
Product Overview Features
Cold-color-changing vinyl adhesive material is a functional composite material developed based on the principle of temperature sensitivity, mainly composed of vinyl substrate, special adhesive layer and temperature-sensitive color-changing microcapsules. This material will trigger a color-changing reaction at a specific low-temperature threshold, changing from transparent or light to dark. When the temperature rises above the threshold, it can reversibly return to its original color. The entire process does not require external energy to drive and is completely dependent on changes in environmental temperature.
Core Features
It is equipped with thermal sensitive microcapsule pigments. When the ambient temperature reaches the preset threshold (such as below 20°C or in contact with the skin), the surface color of the material will automatically change (such as from dark to light or switching to a contrasting color), and return to the original color when the temperature rises again. The color-changing process is reversible and highly repeatable.
Supports customized color-changing ranges (such as 15°C to 30°C) and color combinations (single color/multi-color gradient).
The special surface coating or material formula can absorb heat and bring an instant cool tactile sensation, making it suitable for summer products, sports equipment and other scenarios.
The high-adhesive back design can be firmly adhered to various substrates such as plastic, metal, glass and wood, and is resistant to peeling and scratching.
Waterproof and UV-stable, it does not fade when used outdoors.
Compliant with RoHS/REACH standards, it has no pungent odor and is suitable for products that come into contact with the human body (such as stationery and clothing accessories).
Temperature Sensitive Color-changing Adhesive Material
Material Composition Structure
Typical cold-color-changing vinyl adhesive materials adopt a five-layer structure design:
Surface protective layer: 12μm thick PET film, scratch-resistant and wear-resistant
Vinyl substrate layer: 80-100μm thick PVC or polyester film, providing flexibility and mechanical strength
Thermochromic layer: A coating containing microencapsulated color-changing dyes, with a thickness of approximately 20-30μm
Adhesive layer: 12μm thick acrylic pressure-sensitive adhesive, viscosity 1000-3000cps, with air release channels
Release liner: 180μm thick PE-coated kraft paper, convenient for storage and construction
Application Scenarios
Creative packaging: Wine bottle labels, beverage packaging (low-temperature color display indicates refrigeration status).
Sports equipment: bicycle stickers, helmets, yoga MATS (temperature variation shows usage intensity, cool touch enhances comfort).
Home decoration: Wall stickers, fridge magnets, DIY handicrafts (change color with the seasons or touch).
Smart labels: Cold chain logistics temperature monitoring, anti-counterfeiting marks (color changes directly reflect temperature changes).
Fashion design: Clothing heat transfer printing, shoe and hat accessories (dynamic colors + cool experience).
