Disposable self-heating foot insoles leverage a sophisticated oxidation process. By utilizing ultra-fine iron powder, vermiculite, and activated carbon, our products maintain a constant temperature of 40°C-50°C for up to 12 hours. This is not just heat; it is precise thermal engineering designed for podiatric safety.
The oxygen transmission rate (OTR) is controlled via medical-grade non-woven fabrics. As an OEM manufacturer, we calibrate the membrane density to ensure uniform heat release, preventing localized hot spots that occur in inferior products.
Based in China's high-tech manufacturing hubs, our factories utilize automated production lines that ensure 99.9% consistency in raw material weight, a critical factor for global safety compliance (CE, MSDS, RoHS).
9sexy is a B2B wholesale company specializing in wellness products. Founded in 2020, we have grown into a leading provider in China, serving over 1000 customers globally with flexible OEM/ODM solutions.
30+ dynamic professionals across design, quality inspection, and logistics. Our design department merges creativity with functional science to deliver products that lead market trends.
We apply strict criteria: plant size, R&D capabilities, and delivery efficiency. Being stable buyers allows us to offer prices lower than standard factory rates, passing the profit to our B2B partners.
NINE SEXY supports sourcing with private label services. Every detail is confirmed via 3D drawings and physical prototypes before mass production begins.
The global market for disposable heating products is shifting toward sustainability. Our R&D roadmap for 2025-2030 includes:
Currently, China produces 85% of the world's self-heating products, with our facility leading in energy-efficient manufacturing and carbon-footprint reduction.
We use double-sealed packaging and non-toxic food-grade iron powder. Every batch undergoes a 24-hour heat-consistency test to ensure no leakage or overheating occurs, adhering to international safety standards.
For standard products, there is no MOQ. For customized logos and specific thermal durations, we typically start at 1000 units, but we offer flexible solutions for emerging brands.
Yes. By adjusting the micro-porous membrane’s air permeability, we can design insoles for 6-hour, 8-hour, or 12-hour durations depending on your market's specific needs (e.g., skiing vs. daily commuting).
We partner with top-tier freight forwarders to provide DDP (Delivered Duty Paid) services to the US, EU, and Southeast Asia, minimizing transaction costs and customs delays for our B2B clients.
