IN Brief:
- RAMPF has opened a €8m resin manufacturing and application engineering facility in Tianjin, China.
- The 23,500m² site combines production, warehousing, a laboratory, and application engineering for polyurethane, silicone, and epoxy systems.
- The plant will serve electronics and other industrial customers needing locally developed and qualified sealing, potting, and bonding materials.
German materials specialist RAMPF has opened a €8 million resin manufacturing and application engineering facility in Tianjin, China. The 23,500-square-metre site combines production space, offices, warehousing, a laboratory, and an application engineering centre. It will manufacture polyurethane, silicone, and epoxy systems used to seal, encapsulate, and bond industrial assemblies, including electrical and electronic equipment.
The new plant stands in the Chemical Industrial Park of the Tianjin Economic and Technological Development Area (TEDA). RAMPF has invested approximately RMB 60 million in the operation, expanding its manufacturing presence in China while bringing materials development and customer testing closer to local production lines. The systems serve automotive and electric mobility applications alongside aerospace, electronics, household appliances, packaging, and tooling.
Combining materials development with production is particularly useful when a resin must fit both a component’s operating environment and the process used to manufacture it. A circuit assembly may need protection from moisture, dust, or vibration, but the encapsulant must also be compatible with its housing, conductors, and temperature range. Laboratory work can establish the relevant material properties before dispensing settings and curing conditions are transferred to repeat production.
Potting protects electronics by surrounding components with a cured polymer, although choosing a suitable material involves more than filling the available space. The resin’s dielectric characteristics must suit the circuit, and its expansion and contraction must remain compatible with the parts it surrounds. Excessive shrinkage during cure or mechanical stress during temperature cycling can affect delicate assemblies. Viscosity, working time, and adhesion also determine how readily the material reaches closely spaced features.
RAMPF’s wider product range addresses those requirements through different polyurethane, silicone, and epoxy formulations. Its published electronics materials include low-shrinkage systems and compounds chosen for resistance to water uptake, temperature change, or chemical exposure. These are product-dependent characteristics rather than universal properties of the three resin families. The appropriate formulation depends on whether the assembly is a sensor, an electrical connector, a control module, or a higher-power unit.
Power electronics place an additional demand on the encapsulation design because the active devices generate heat. Thermally conductive potting compounds and gap-filling materials can help create a heat-transfer path towards a heat sink or enclosure, provided the geometry and interfaces are designed for that purpose. RAMPF lists thermally conductive epoxy systems within its broader portfolio. Electrical insulation, mechanical protection, and heat flow therefore have to be considered together when qualifying an assembly.
Before curing, many reactive systems require two components to be mixed and metered in the correct ratio. Their viscosity and available processing time influence the filling of narrow spaces and the risk of trapped air. Dispensing accuracy, component positioning, and curing conditions can affect the consistency of the finished part, particularly on automated lines. The company’s application engineering facilities support the testing of such material and process combinations; specific dispensing equipment installed at Tianjin has not been detailed.
Sealing and bonding have different duties even when they use related chemistries. A seal around an electronics housing or battery enclosure must form a barrier suited to the expected exposure, while an adhesive joint must retain its bond across the chosen substrates and service conditions. RAMPF’s Tianjin operation produces resin systems for all three applications — sealing, potting, and bonding — as well as tooling, giving customers a local source for several materials functions.
Tiger Meng, CEO of RAMPF China, said the investment reflects a commitment to supplying customers locally with tailored formulations and application expertise. He identified silicone-based systems for automotive applications as one area of opportunity. Michael Rampf, CEO of RAMPF Group, credited cooperation between the German and Chinese teams for delivering the project, and acknowledged support from the TEDA administration.
The opening follows an earlier investment programme that established the Tianjin site’s planned footprint and manufacturing purpose. Its completion adds operational capacity rather than a new electronics product launch. In a separate programme for electronica 2026 in Munich, RAMPF will display potting compounds and automated mixing and dispensing systems, illustrating the range of process technologies it supplies to electronics manufacturers.
Those machines belong to RAMPF’s wider production-systems portfolio and should not be confused with equipment confirmed at the Chinese factory. The Tianjin site is established as a resin production, laboratory, and application engineering operation. Its combination of functions allows customer-specific formulations and process trials to be handled in the same regional manufacturing network, with material qualification determining the eventual application.
RAMPF is also examining further investment possibilities, including polyurethane recycling, although no additional recycling installation has been confirmed for Tianjin. The immediate operational change is the availability of locally manufactured reactive resins supported by testing and application engineering, with subsequent production programmes dependent on the materials selected and qualified by customers.
