- Polyurethane resin has a series of properties that make it an ideal product for use in electronics and electricity.
- Encapsulating capacitors and circuits provides protection against corrosion, moisture, chemicals, shock, dissipates heat, etc.
- With some variations in the formula you can transform a resin, which is an electrical insulator, into a conductor, opening a new range of possibilities.
- In Formulations we have an R & D department with the necessary resources to manufacture any solution that our clients may need, specific to each requirement in the case of the electrical, electronic, motorization, etc. sector.
Its properties allow multiple applications
The first way in which polyurethane was found useful was as foam. But if the foaming agents are removed, a resin with very surprising properties can be obtained.

Having no longer a cell structure, which gives it its foam form, loses the property of thermal insulation, but gains other very interesting qualities such as high hardness and resistance to compression, resistance to environmental elements (except for the UV rays), high dielectric strength and heat dissipation capacity. These characteristics make polyurethane resin an ideal product for use in electronics and electricity.
Encapsulation of circuits and capacitors
On the motherboards of many computers you can see capacitors and circuits covered with a hard product with a vivid color and a smooth surface. That product is the polyurethane resin that is used to encapsulate them and that protects them from corrosion, humidity, chemicals and shock. It also dissipates heat, prevents discharges and overloads and prevents the circuit layout from being copied, thus preventing its falsification (thus protecting intellectual property).
In addition, with slight variations in the formula you can transform a resin that is an electrical insulator into a conductor, opening a new range of possibilities.
Polyurethane resin is also used to protect the circuitry of lightning rods and prevents them from overloading when lightning strikes.
The epoxy resin in electronics
Another polymer that is used in electronics is epoxy resin. This has as an advantage, compared to the polyurethane resin, which is transparent and if it has protection against yellowing by UV rays it can be used to cover the LED lights, giving them protection and allowing the light to pass without problems.
