Instructions for Use
1. Clean the surface and heat dissipation structure of the heating element with anhydrous ethanol, remove oil and dust, and air dry until there are no residues;
2. Confirm that the product thickness matches the installation gap, cut it to the required size as needed, and remove the protective film on the surface of the thermal pad;
3. Align the installation position with the thermal pad and lightly press it to ensure full contact between the thermal pad and the surface, ensuring no residual bubbles;
4. In conjunction with screw locking or buckle fixation, it is recommended to apply a pressure of 20-60psi to ensure a stable fit without the need for additional adhesive coating.
Precautions
Storage conditions: Sealed and stored in a cool and dry place (8-30 ℃), avoiding direct sunlight and high temperature and humidity environment. Shelf life is 12 months from the date of production
Usage taboos: Avoid contact with strong acids, bases, and organic solvents, and prohibit use in food contact scenarios and extreme vacuum environments
Thickness selection: Choose the appropriate thickness based on the installation gap, and it is recommended to reserve 10-20% compression to ensure the fitting effect
Customization Description: Supports cutting customization within the thickness range of 0.5-8.0mm, specific length and width dimensions and required thickness need to be provided
