Heat conductive sheet
Peace of mind through siloxane-free heat countermeasures
Product overview
- Siloxane-free
TM sheet does not generate low-molecular-weight siloxane which causes problems such as contact failure and optical lens clouding.
Amount of detected siloxane
- (Note) Values were measured using a method selected by FEPS
- Environmental friendly
All TM Sheets comply with environmental regulations such as ROHS, REACH, and North American TSCA. The sheets do not contain the hazardous substances halogen, lead, and chlorofluorocarbon. - Low VOC (volatile organic compounds)
Materials and manufacturing methods that generate lower emissions are used. The amount of gas generated is less than that of typical thermal conductive sheets.
Reduces the risk of corrosion of components (connectors, wiring, etc.) and clouding of optical components.
VOC generation amount
- Low oil bleed
Lower oil bleeding than typical silicone products. - Easy handling
The two-layer structure of a thin PET film and main layer achieves durability and easy handling (for VHT, VFT, EE-RT).
- (Note) Do not remove the PET film.
- (Note) The PET film is somewhat wrinkled during the manufacturing process. The wrinkles are smoothed when pressure is applied, so there is virtually no effect on heat resistance.
Use
- General industrial use
High-performance printers, semiconductor manufacturing equipment, optical equipment, communication equipment, measuring equipment, liquid crystal displays, LED lighting, servers, storage, etc. - Automobile use
Automotive navigation systems, various control devices, hybrid/EV power supplies, cameras, etc. - Digital devices use
Computers, digital cameras, HDDs, TVs, video games, etc.
Lineup
Standard type: EE-RT
The sheet has a two-layer structure consisting of an acrylic body and a PET film. The sheet is rigid, possesses high thermal conductivity, and is easy to handle.
The thickness is 0.3mm, which is the thinnest among non-silicon products. This creates an advantage in terms of thermal resistance.

High heat conductive type: VHT
This sheet has a two-layer structure consisting of a main body made of thermoplastic elastomer and a PET film. It has the highest thermal conductivity of any non-silicon sheet.

Soft type: VFT
This sheet has a two-layer structure consisting of a main body made of thermoplastic elastomer and a PET film. It possesses excellent flexibility.
The sheet is designed to alleviate compressive load on the substrate and parts, absorb the gap tolerance between the object and the radiator, conform to undulations when adhered to an uneven surface, and reduce thermal resistance due to close contact.

- *3 The tacky side of TM Sheet does not adhesive; however, it has the inherent tackiness of rubber. This makes the sheet slightly adhesive. (HF-N is a non-adhesive film type that is basically non-adhesive, but can be coated with adhesive on one side as an option).

Thermal performance test method
Thermal conductivity
Thermal conductivity is measured in accordance with the hot-wire method defined by JIS-R2616 using Quick Thermal Conductivity Meter made by Kyoto Electronics Manufacturing Co., Ltd. The measurement sample must be at least 10 mm thick.
