LiPOLY’s TPS31/TPS32 is a low-density, two-part compound silicone base thermal conductive sealing material. It’s low viscosity and excellent fluidity can tightly fill the gaps of electrical components and cover the tolerances between components. It has excellent thermal conductivity, low density and insulation properties.
FEATURE
- Lightweight, Low Density, Thermal Conductivity 0.55 & 1.5 W/m*K
- Medium-to-high hardness silicone material with excellent insulation and weather resistance
- Suitable for automatic dispensing machine
- TPS31 Moisture absorb hardening reaction at room temperature.
- TPS32 Hardened at room temperature, also can be heated to accelerate the hardening reaction.
APPLICATION
- Heat Dissipation & lightweight applications, such as Automotive electronic devices, Mobile communication device, Drone & aircraft, Sports and leisure electronic products, Portable game consoles, VR devices and etc.
- 5G base station & infrastructure / EV electric vehicle
