SP265 1:1 removable property and aging resistance properties 2-component polyurethane thermally conductive adhesives sealant for bonding between energy storage
A Two-component Silicone and Polyurethane gap filler for every need
SEPNA thermally conductive liquid gap fillers are highly flexible solutions for consistent thermal conductivity, high insulation, and effective electrical isolation.
Chemically tunable gap fillers can be specified to highlight every important characteristic you need.
Our PU and Silicone gap fillers are suitable for various model platforms, uneven surfaces, and thicknesses. SEPNA works with major leading dispensing equipment manufacturers worldwide to help ensure efficient automated application. SEPNA provides thermally conductive gap fillers in pails and drums and can provide them in 400ml double plastic tubes for initial prototyping.
Designed for EV and energy storage battery applications
- Thixotropic fluid ensures complete module coverage, prevents excessive stress in finished parts, and avoids air entrapment and the associated re-work
- Colored material allows for an immediate quality check during mixing
- These chemically tunable liquid gap fillers are available with semi-structural strength, or for low or no adhesion so they can be peeled off for easy reworkability
The model SP265 is a Two-component paste polyurethane thermally conductive adhesive, mixed 1:1 by mass and cured to a high-performance elastomer that molds to the structure's shape, providing the best structural suitability and surface fit of structural components. It meets the needs of low stress and high compression modulus and can be automated. Low contact thermal resistance and high electrical insulation when assembled with electronic products. Healthy and environmentally friendly, RoHS compliant.
Efficiency in automation
- With a mixing ratio of 1:1, these thermally conductive liquid gap fillers make for a robust process that uses the same interchangeable machine parts for all equipment
- They apply at room temperature with no pre-heating of equipment and tubes for reduced time and energy expenses
- SEPNA polyurethane thermally conductive adhesive support fully automated dispensing with high throughput
- Form-in-place curing eliminates processing and die-cutting and accommodates large and exacting tolerance stack requirements
Enabling supply chain flexibility
- SEPNA Two-component (2K) material (polyurethane and silicone)can be transported without refrigeration and delivers a long shelf life
- It is mixed at the point of application, which helps reduce waste and eliminates the need to circulate each part before use
- Instead of multiple products, order one solution to meet a wide range of specifications
