Material science meets wearable warmth
Faster warm-up. Even surface heat. Safer temperature control. Every FlexTherm heating film is engineered, lab-tested and mass-produced in-house — then tuned to your product, your certification path and your brand.
FlexTherm engineering & testing
We keep pushing carbon nanotube heating further — here is what our in-house R&D and QC team delivers for OEM / ODM partners.
- Custom projects 0+ 120+ custom heating projects developed for global brands, Amazon sellers, Shopify labels and gift companies
- Durability 0+ 10,000+ bend cycles validated on our CNT film and flexible electrodes, with resistance drift kept inside spec
- Warm-up 0s 3-second warm-up with NTC smart control holding target temperature and cutting power on fault
Validated with partners
you already trust
FlexTherm works with independent laboratories, certification bodies and university research groups around the globe to validate every carbon-nanotube heating system we build — so the brands, Amazon sellers and therapy companies we manufacture for can ship with total confidence.
Every CNT heating film batch is tested for surface-temperature uniformity, NTC accuracy and 10,000-cycle flex endurance.
Meet the minds behind FlexTherm's science & innovation
Flexible heating engineered by specialists in carbon nanotube materials, wearable electronics, thermal safety and physiotherapy — the team global brands, Amazon sellers and health-tech companies build their heated products with.
01
CNT Heating Film
Dr. Wei Lin, PhD
Head of Carbon Nanotube Materials
Leads dispersion, coating and film uniformity — the core of even, far-infrared heat across every surface.
02
Flexible Electrodes
Amanda Ye, MSc
Director of Wearable Engineering
Turns 0.2mm heating layers into washable, foldable wearables that survive 20,000+ bend cycles.
03
NTC Smart Control
Marcus Feld, MEng
Lead, Thermal Safety & NTC Control
Owns ±1°C regulation, over-temperature cut-off and certification for CE, FCC, UL and RoHS.
The proof is in the science
Lab-tested and certification-backed data behind every FlexTherm carbon nanotube heating platform. Whether you are launching a therapy line on Amazon, a wearable brand on Shopify, or a premium corporate gift program — the engineering is already proven.
CNT Heating Film
Far-Infrared Therapy Pads
Key findings from lab validation:
- Reaches a stable 45°C surface temperature in under 30 seconds
- Even heat field with ±2°C deviation across the whole panel
- 8–12µm far-infrared band for deeper tissue penetration
Wearable System
Heated Apparel & Wearables
Verified in accelerated wear testing:
- Survives 10,000+ bend cycles with no resistance drift
- 0.28 mm film thickness — invisible inside a garment lining
- Machine-washable construction, IPX4 sealed harness
- Runs on standard 5V / 7.4V / 12V power banks
NTC Smart Control
Smart Temperature Control
Measured on the NTC control board:
- Closed-loop NTC sensing holds the set point within ±1°C
- Dual over-temperature cut-off plus auto shut-off timer
- Optional Bluetooth app control with 3–5 heat levels
Flexible Electrode
Heated Gloves, Socks & Insoles
Cold-chamber test results:
