Thermal Management Products for LEDs

The thermal management of the LED and the unit is a vitally important consideration for the reliability of an LED unit.
  • Thermal Pastes
  • Phase Change Material
  • Gap Pads
  • Thermal Bonding
  • RTVs
  • Encapsulation Resins

The thermal management of the LED and the unit is a vitally important consideration for the reliability of an LED unit. A variation of just one single degree centigrade can effect both the life of the LED, (the higher the temperature the unit is running at the faster the luminaire degrades) as well as the efficiency, ( the lower the temperature, the more efficient the luminaire is at producing light).

With a single degree centigrade of heat having such a large effect on the efficiency and the lifetime of an LED Luminaire, the thermal interface material chosen for the LED design is of vital importance.

Electrolube offer a wide range of thermal interface materials including curing and non-curing pastes, gap pads, phase change materials (facilitating easy rework), as well as a selection of encapsulation resins which are designed to dissipate the heat away from the components to the housing.

If you have any questions our dedicated technical support team are on hand to answer your questions and don’t forget that our LED brochure contains vast amount of collaborative test data from Bridgelux comparing data to help you select the right material.

UR5097 - Black Polyurethane Resin

UR5097
Black Polyurethane Resin

250g - 5kg - 10kg - 25kg kits

Product code: UR5097RP250G - UR5097K5K - UR5097K10K - UR5097K25K


This thermally conductive Polyurethane encapsulation and potting compound is a two part system with a black finish. It exhibits excellent thermal conductivity making it ideal for applications where heat dissipation is required.

The cured polyurethane is resistant to a wide or cycling temperature range making it an ideal choice for applications where thermal shock is a potential risk to the electronics, while it is also flame retardant to UL94 certification.

Its low water absorption offers exceptional protection against moisture in humid environments or water that may be present.


Key Properties:
  • Flame retardant, certified to UL94 V-0
  • High thermal conductivity
  • Low water absorption
  • Excellent electrical properties
  • Does not contain abrasive fillers and has good flow characteristics; low wear on dispensing machinery
