Performance Silicones Portfolio
Silicones in standard vehicles
Why Silicone for Battery Applications?
Thermal Stability
- High temperature resistance
- Wide temperature range retention of elastomeric properties
Tunable: Modulus/Hardness/Cure chemistries
- Hardness range from hard to soft depending on application
- Flexible/compliant, retains flexibility at high filler (thermal, electrical) content with high elongation at break
- Fast RT cure for large component fixing and increased productivity
Thermal management performance
- Wide thermal conductivity range available
- Silicone provides low thermal resistivity
Thermal event isolation
- Slow the spread of thermal events in lithium ion battery
Light weighting
- Silicone foams meet UL requirements with low weight
Silicones in Battery Pack Assembly
Battery Pack Assembly
Assembly and integration of EV/HEW batteries and modules require mechanical fixing, thermal management and vibration damping. We provide DOWSIL solutions for all of these applications.
Silicone-based materials enable customers to cost-effectively manage the challenges in their next-generation EV/HEV battery assembly designs.
Advancing your Battery Pack Assembly
Portfolio of Advanced Thermally Conductive Materials: Focus on Gap Fillers
Introducing: thermal runaway propagation prevention
- Silicones can slow the spread of thermal events in lithium ion battery applications
- Filled or unfilled silicones available:
- Gap fillers
- Foams
- Encapsulants
- Gels
- Application requirements determine material selection
- Silicone foams can be a light weight alternative to traditional encapsulant and sealant options.
- Foam encapsulant can provide cell protection in the case of a thermal event.
Silicone Foam flammability testing
Dow Silicone Foam Products – Commercially Available
Introducing: EMI Shielding
Increasing density of electronic components in many market segments.
Shielding prevents cross-talk of electronic circuits, detectors, RF signals.
Silicones provide flexibility over a wide range of temperature and environmental conditions
Electrically Conductive Silicones
- Formulation.
- Polymer- Able to tune rheology, mechanical performance, adhesion, stability
- Filler- Electrical performance, rheology, cost, stability
- Additives- Cure dynamics, stability, shelf life
- Characterization Mechanical
- Electrical
- Chemical
- Application testing
- Dispensing
- Accelerated stress testing
- Electro-mechanical characterization
Conformal Coatings
Key Benefits
- Improves reliability in humid environments.
- Protects PCBs and other electronic components against environmental particles, moisture and contaminants, preventing sort circuits nd corrosion of conductors and solder joints
- Protects circuits and components from abrasion and solvents
- Stress relieving
- Protects insulation resistance
- Reduces conductor spacing on PCBs
- Good dielectric properties (insulation, moisture resistance, breakdown voltage)
