—— A reliable and removable protective option after curing. In applications such as industrial automation, smart manufacturing, and energy control, industrial controllers operate in environments with high loads, high temperature rises, strong vibrations, and complex conditions for extended periods.
The key challenge in the potting design of industrial controllers lies in balancing efficient heat dissipation with the removability for future maintenance, repair, and upgrades.
Addressing this industry pain point, ELAPLUS has launched SIPA 1850, a low-stress, removable thermal conductive potting adhesive, providing a more reliable and flexible potting solution for industrial controllers.
- Core pain points of potting for industrial controllers: Traditional potting for industrial controllers often employs epoxy materials, which, despite their high strength, also brings about notable drawbacks:
❌ Non-detachable after curing, making repair essentially equivalent to scrapping ❌ High internal thermal stress, prone to cracking of solder joints and components ❌ Decreased reliability after thermal cycling ❌ Not conducive to product upgrades and rework. Modern industrial controllers, however, place higher demands on potting materials:
✔ Possesses stable thermal conductivity, reducing the operating temperature of the device ✔ After potting, exhibits good moisture resistance, vibration resistance, and electrical insulation properties ✔ After curing, is removable and repairable, enhancing the overall lifecycle value of the device
II. Solution Recommendation: SIPA 1850 Thermal Conductive Potting Compound Product Positioning SIPA 1850 is a low-stress, self-adhesive, silicone thermal conductive potting compound specifically designed for electronic control systems that require heat dissipation and maintainability.
III. Core Advantages of SIPA 1850 1️⃣ Efficient Heat Conduction and Stable Heat Dissipation: The thermal conductivity is stable and fast, effectively conducting the heat generated by power devices (MOS, IGBT, power modules, etc.) to the housing. This significantly reduces the temperature of hot spots inside the controller, enhancing system stability. 👉 It is particularly suitable for industrial control modules with high power density
2️⃣ Low-stress curing: After curing, the silicone elastomer system, which protects sensitive devices, maintains good flexibility and toughness, effectively absorbing thermal expansion and contraction as well as mechanical vibration stress. 👉 Compared to epoxy encapsulation, it significantly reduces the risk of solder joint cracking and device failure
3️⃣ Removable after curing, supporting repair and upgrade. This is one of the key advantages of SIPA 1850:
After curing, it presents an elastomeric state and can be removed through mechanical means or local heating, unlike epoxy potting which “permanently binds” to the device. 👉 Applicable to:
Industrial controller rework prototype debugging Small batch customization equipment High maintainability requirements for systems 4️⃣ Excellent protective performance Good waterproof and moisture-proof capabilities Stable electrical insulation performance Adapt to complex industrial environments (dust, humidity, vibration) View SIPA 1850 details IV. Typical application scenarios SIPA 1850 is widely applicable to the following industrial control fields:
Application scenarios of sensor potting compound: potting of main control boards in industrial controllers, potting of industrial power modules, thermal potting, control units for automation equipment, and local potting of frequency converters and drivers. Electronic modules that require “heat dissipation + maintainability” are in demand. With the development of industrial controllers towards high integration, high reliability, and maintainability, potting materials are no longer just for “sealing”, but have become an important component of system reliability design.
SIPA 1850, a thermally conductive and removable potting compound, not only ensures excellent heat dissipation and environmental protection for industrial controllers, but also preserves more possibilities for maintenance, upgrades, and long-term use
