Explore our globally verified heating and cooling therapy product line, developed with precise thermal properties and medical-grade manufacturing standards.
Established in 2006, Tianjin Fuqin Science & Technology Co., Ltd. has dedicated over 18 years to R&D, precision manufacturing, and global supply chains for advanced warming technology. Holding more than 100 independent patents, we represent a premium source for healthcare brands, industrial buyers, and global distributors seeking high-performance thermal devices.
We optimize chemical exothermic reactions using high-grade raw iron powders, active carbons, and precisely engineered microporous membranes. Our custom hand warmer pouches generate consistent, reliable warmth for up to 24 hours.
Bridging the gap between traditional chemical heat and modern wearable tech, our graphene-infused heating systems release deep-penetrating infrared waves, perfect for medical-grade physiotherapeutic products.
Our state-of-the-art hydrogel production lines produce high-water-content polymers for instant, localized cooling. We offer targeted relief options, from fever patches to customized ocular cooling therapies.
As a premier custom hand warmer pouch manufacturer, Tianjin Fuqin excels in tailoring the thermodynamic release curves of air-activated warming systems. The heating mechanism utilizes a precise blend of raw iron powder, water, vermiculite, activated carbon, and salt.
When the pouch is removed from its outer barrier film, oxygen permeates the inner microporous wrap. The oxygen reacts with the iron powder, forming iron oxides. Our chemical team manages this process to maintain safe, comfortable heat levels.
We adjust the air flow rate by altering the pore density of the PE breathable film. This directly controls the rate of the oxidation reaction, allowing us to build products with custom warming windows (e.g., 8, 12, or 24 hours).
Vermiculite acts as a heat retainer, while carbon ensures even oxygen distribution. This prevents sudden spikes in temperature and keeps the product at a steady, therapeutic temperature (typically 53°C to 63°C).
Each batch undergoes strict testing to verify thermal consistency. We use infrared thermography to track heat distribution across the surface of the pouch, ensuring zero cold spots and absolute safety against thermal burns.
This level of quality control is essential for medical-grade applications, such as menstrual heat patches, pain relief waist belts, and therapeutic neck wraps.
B2B sourcing requirements for hand warmers and medical heat patches differ by industry. Tianjin Fuqin offers bespoke supply solutions tailored to each sector's unique regulatory, shipping, and design demands.
For outdoor sports brands, retail packaging, shelf appeal, and customized pouch shapes are vital. We offer tailored packaging structures, custom sizes, and custom prints for retail programs.
Healthcare brands require certifications like ISO 13485 and CE MDR. We manufacture body warming and cooling products with medical-grade adhesives, biocompatible fabrics, and precise heat profiles.
Workers in cold-chain logistics require heavy-duty warming products. We supply bulk, high-duration adhesive warmers designed to keep personnel warm during long shifts in freezing conditions.
Tianjin Fuqin offers comprehensive OEM and ODM support, managing every step from concept and material selection to production and compliance check.
With 18+ years of OEM experience, we deliver tailored production runs. Our services cover customized shapes, brand prints, specific packaging types, and custom temperature ranges.
Our engineering team designs custom heat therapy solutions from scratch. We help you choose the right fabric, develop the chemical recipe, design the packaging, and secure the necessary certifications.
For clients needing fast turnaround times, we maintain inventory of our standard warming and cooling products. This ensures quick dispatch to meet tight retail windows.
Navigating customs requirements and healthcare regulations is a priority for international shipping. Tianjin Fuqin maintains a complete set of global quality certifications.
Ensures all our heat wraps and cooling gel patches meet European Medical Device Regulation safety standards.
Certified Quality Management System for manufacturing medical devices and therapy products.
Reflects our commitment to fair working conditions, ethical practices, and environmental standards.
Provides full material safety datasheets for transport clearance, enabling air and ocean shipping.
Our products are trusted in highly regulated markets, including the United States, Germany, the United Kingdom, and Russia. We support our logistics partners with complete documentation for smooth customs processing.
We continuously develop advanced thermal care solutions. Our technical team works on next-generation materials, eco-friendly components, and digital heating technologies.
We are expanding our product line to include low-voltage electric heating items powered by graphene. These carbon-based systems deliver clean, direct heat therapy without bulky wires.
To address packaging waste, our material science lab is developing plant-based, biodegradable films. These films aim to replace standard plastic barrier wraps.
Building on our steam eye mask line, we are designing localized warming patches that release micro-steam to soothe skin and boost transdermal lotion absorption.
