In October 2011 MTC was acquired by the UK-listed company Acal plc. With a turnover of more than 250 million euro and over 750 employees worldwide Acal has evolved into an important international service provider - with focus on the distribution of electronic and photonic components, power supply and system components. Acal has offices in 12 European countries. Thus MTC also grows internationally and ensures its customers local presence and pan-European support.
MTC has manufacturing sites in Germany and South Korea. With Regens-Wagner-Stiftung, a facility for disabled people in Dillingen and our sister company EMC Innovation in Incheon we guarantee our customers short reaction times and high flexibility.

Thermally Conductive Paste Thermally conductive paste is the most common material used in systems and devices for thermal management. Main criteria for choosing thermally conductive paste are the thermal properties as well as the processing capacities. Thermal conductive paste builts a thin binding film for very good thermal conductivity through the low thermal resistance. With electronic systems and equipments are getting smaller and, at the same time, clock speed is rising, thermal management becomes more and more important. Heat must be transferred from the component to the heat think or any other type of cooling device because heat causes: • slower operation speed • early failures • other power problems.
Due to low viscosity of the material it can be applied by silk screening or masking technology. Our product range includes thermally conductive pastes with a thermal conductivity between 0.9 up to 4.5 W/m*K.
Item number To increase heat dissipation it is suggested to use thermally conductive products as a connection between the „hot spot“ and the cooling device. The connection (without use of an appropriate thermally conductive product) can consist of air up to 80%. Thermally conductive materials have been developed to compensate uneven surfaces. By displacing the air with a highly conductive material heat dissipation is increased and the module is better cooled.

Gap fillers are supplied as die cut gasket or in standard sheets. As far as the thermal conductivity is concerned, material between 1,0 W/m*k to 7 W/m*K is offered. Gap Fillers are sticky by nature. This can be single- or double-sided. The use of double-sided adhesive tapes is not necessary in most cases.
Example how to order: Looking for a standard sheet in thickness of 2.5 mm with a thermal conductivity of 3.0 W/m*K. Material should be ultra soft and sticky on one side. Item number: TCGF-3,0-UW-210x297x2,5-SST

Thermally Conductive Tapes
Thermally Conductive Insulators
Thermally conductive adhesive tapes are used for bonding heatsinks and other cooling devices with the warm component.
Thermally conductive insulators are characterized by a good heat dissipation and an excellent dielectric strength.
The tapes can be supplied as double sided adhesive film or with fibre glass carrier. They are filled with thermally conductive ceramic or metallic particles.
Insulators are mainly used with power transistors, such as TO-220, TO-247 and IGBTs. The material is available in thicknesses from 0.13 - 0.5 mm.
an acal group company
Thermally conductive tapes eliminate the need for external clamps and curing. Depending on the material, the thermal conductivity is between 1.5 and 3.0 W/m*K . Other characteristics are: high bond strength to surfaces • thermal conductivity in combination with electrical isolation • excellent wet-out • very high temperature stability •
