Thermal Management Challenges in Modern Electronics
As electronic assemblies become smaller and more powerful, engineers and technicians face increasing challenges in thermal management. Without effective heat dissipation, component temperatures rise critically, reducing lifespan and potentially causing system failure.
To ensure reliability and durability, heat must be efficiently transferred from the source (electronics) to the sink (e.g., heatsink). This is where Thermal Interface Materials (TIMs) come into play.
As your trusted partner for electronic components, alfatec offers innovative solutions from KERAFOL®, including KERAMOLD® injection molding compounds - a state-of-the-art answer to demanding thermal and electrical insulation requirements.
What Is KERAMOLD®? An Innovative Injection Molding Compound
KERAMOLD® is a thermally conductive injection molding compound developed by KERAFOL®, based on thermoplastic elastomers (TPE). It goes beyond traditional 2D heat transfer paths of foils or pads by enabling three-dimensional thermal conduction with high electrical insulation.
Delivered as granulate, KERAMOLD® can be processed using standard injection molding techniques. A key feature is the overmolding process: electronic components or entire PCBs can be directly encapsulated with molten KERAMOLD®. This not only provides excellent cooling but also protects sensitive electronics from dust, moisture, and mechanical stress. With short cycle times, KERAMOLD® is a cost-effective and technically superior alternative to conventional potting compounds.

Key Technical Parameters
KERAMOLD® from alfatec offers the following outstanding properties:
- Material Base: Thermoplastic elastomer (TPE)
- Thermal Conductivity: Up to 2.5 W/mK
- 3D Heat Transfer: Effective in all directions
- Electrical Insulation: High dielectric strength (>16 kV for types 15 & 25)
- Mechanical Properties: Soft (Shore A), gentle on sensitive components
- Delivery Form: As granulate or finished molded parts
- Protection: Encapsulated components are shielded from environmental influences
- Processing: Compatible with standard injection molding and low-pressure overmolding
Processing Methods
KERAMOLD® can be integrated into existing production processes. alfatec provides guidance on the best method for your application:
- Conventional Injection Molding: Suitable for producing complex 3D geometries such as housings, heat spreaders, or insulating fixtures. Despite high filler content, the material flows well.
- Overmolding: Enables full or partial encapsulation of assemblies (e.g., PCBs, sensors). Designed for low-pressure molding to avoid damaging sensitive electronics.
