Polymer Compositions Based on Environmentally Friendly Plant and/or Animal Oils as Thermally Conductive Materials

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a thermally conductive material, such as a paste or grease, that uses environmentally friendly polymers made from vegetable and/or animal oils combined with thermally conductive fillers (like carbon nanotubes, graphite, or metals). The process ensures stable embedding of the fillers within the polymer matrix, resulting in a material with good heat transfer, long-term stability, and low toxicity, making it suitable for use in electronic devices and other applications requiring efficient heat dissipation.

Use CasesContent extracted from patent full text and abstract with AI.

• Thermal interface materials for electronic devices (such as CPUs and GPUs) to enhance cooling.
• Heat management in power electronics and electric vehicles.
• Use in LED lighting for improved thermal performance and longevity.
• Integration into battery packs or charging systems to reduce overheating risks.
• Medical devices that require efficient heat dissipation.
• Eco-friendly alternatives to silicone- or petroleum-based thermal greases and pastes.

BenefitsContent extracted from patent full text and abstract with AI.

• Environmentally friendly: based on renewable, biodegradable vegetable or animal oils.
• Non-toxic and safer for manufacturing and end use compared to conventional materials.
• Improved long-term stability including reduced phase separation ('bleeding') and thermal expansion ('pump-out').
• Customizable viscosity and material properties for various industrial needs.
• Competitive or improved thermal conductivity relative to existing commercial pastes, especially with carbon nanotube fillers.
• Good adhesion and spreadability on different surfaces, including rough or uneven contacts.
