Product Description

What products do we make?
 

SEPNA SS268 Silicone Thermally conductive adhesives are used on cooling plates and tubes to help conduct heat away from the batteries and toward heat sinks.

The model SS268 is a paste gap filler, 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.

 1:1 ratio Two-part silicone glue adhesive for Electric vehicle battery module

 

Special features
 

 

 
1. Thermal conductivity 2.0W/m.k;
2. It can be removable;
3. Excellent effect in filling irregular structure gaps.
4. Low stress, high compression ratio.
5. High electrical insulation.
6. Excellent mechanical properties and weathering resistance.

 

Different thermal conductivity can be customized

( Thermal conductivity :( 0.3-3.0 W/m.k )

 

0.3 W/m.k For SP280.SP281.SP282.SP283

1.2 W/m.k For SP284.SP286.SP261

1.5 W/m.k For SP263.SP287

2.0 W/m.k For SP265.SP268.SP285

3.0 W/m.k For SS269
 

Two-component thermally conductive silicone gap filler


The bonding strength has high, medium, and low strength and is Removable (when the future battery pack is bad after replacing the new battery).


Excellent aging resistance and chemical resistance

 
 

Light-weight

Total vehicle weight is tied inextricably to the range of electric vehicles.
The battery pack is a major contributor, typically weighing between 600 and 700 kilograms for the average battery electric vehicle (BEV).

Smart lightweight designs can counterbalance part of this, and Sepna's engineering expertise and partnership with RLE International are fundamental for optimizing aluminum structures per crash standards and passenger safety.

 

Typical Applications
 

 
1. Used in communication equipment, automotive electronics;
2. Used in storage equipment, consumer electronics
3. Used in computers and peripheral equipment, with excellent insulation and heat dissipation, waterproof and moisture-proof.
4. Thermal conductive bonding of the energy storage battery module PACK box between the cooling plate.
