Custom All-Polyimide Heaters with Flexible Lead Encapsulation
Minco’s low-outgassing flexible heater construction supports thermal control of spacecraft instruments, electronics and structures. The all-polyimide (AP) heater is engineered to the required shape, size and electrical performance, with a flexible lead termination designed to improve strain relief and conformability on curved surfaces.
Custom engineered and built to order: these heaters do not have a standard catalogue model or preassigned part number. A part number is assigned after the heater has been engineered to your requirements.
- NASA S-311-P-841-compliant construction with custom flexible lead encapsulation per the manufacturer’s revision to section 3.4.1.5.
- Low-outgassing materials for vacuum and spaceflight applications.
- Custom geometry, resistance, wattage, voltage, lead configuration and mounting.

How to Request a Custom Heater
Send Mod-Tronic your available mounting envelope or drawing, surface shape and curvature, required temperature range, available voltage, target heat output or warm-up requirement, and expected operating environment.
- Specify available area, cutouts, zones, attachment method and heat-sink or substrate details.
- Identify resistance and tolerance requirements, lead length and insulation, connector or termination needs, and any sensor or control requirements.
- State vacuum/outgassing limits, NASA S-311-P-841 documentation, inspection/testing and traceability requirements.
- Include anticipated prototype and production quantities, target schedule and any drawings.
Part numbers are assigned after engineering review and definition of the customer-specific heater. There is no standard model number to select or configure on this page. Final ratings, construction and qualification documentation are confirmed for the agreed design.
Flexible Lead Encapsulation
The proprietary flexible lead encapsulation replaces a conventional rigid hardened-epoxy lead exit. It is intended to improve strain relief and retain conformability through handling and thermal cycling while reducing the risk of cracking or delamination.
Qualification
The supplied datasheet reports NASA S-311-P-841 Group A Quality Conformance Inspection and Group B Qualification Testing for the described construction. These include electrical, thermal-shock, low-temperature, lead-pull and life tests as applicable. Confirm the required construction, test programme and documentation for the customer-specific design.
