High Heat-Resistant Foam for Drone Parts
What is SunForce™ High Heat-Resistant Foam for Drone Parts?
SunForce™ is a bead foam made from Asahi Kasei’s modified PPE resin “XYRON™.” Like general-purpose foams such as expanded polystyrene (EPS) and expanded polypropylene (EPP), it can be processed using similar molding processes.
In addition to the typical foam properties of lightweight and thermal insulation, it also offers high heat resistance and high rigidity unique to engineering plastics.
Furthermore, since SunForce™ uses small-diameter beads, it is suitable for thin-walled and complex-shaped molding, enabling efficient production of components.
Advantages of SunForce™ as a Material for Drone Parts
- Lightweight and High Rigidity：Achieves both drone weight reduction and stable flight.
- High Weatherability：Complies with UL746C f1 standard, offering high durability with minimal UV degradation.
(For details on SunForce™ weatherability, click here) - Low Water Absorption：Hardly affected by outdoor humidity.
- High Heat Resistance：Less deformation and strength reduction due to heat compared to other materials.
- Thin-Walled Molding Possible：Can be produced by mold forming even for drone blades.

Features of SunForce™ as an FRP Core Material for Drone Parts
Recently, to achieve lighter and more rigid drone parts, the use of composite materials that laminate fiber-reinforced plastics (FRP) such as carbon fiber (CF) or glass fiber (GF) with foams is expanding.
Below are the features of SunForce™ as a core material for FRP composites.
- High Heat Resistance:
As an FRP core material, SunForce™ has higher heat resistance than EPS or EPP, making it compatible with high-temperature composite molding with prepregs containing carbon or glass fibers. It is suitable for major composite molding processes such as “autoclave method,” “PCM (Prepreg Compression Molding) method,” and “RTM (Resin Transfer Molding) method,” with increasing adoption in PCM processes.
- Mass Productivity (Cost Reduction):
Unlike board-type foams such as PMI (polymethacrylimide), SunForce™ does not require cutting processes, achieving both mass productivity and cost reduction, and bringing innovation to FRP composite molding processes.
Thanks to these features, FRP composites using SunForce™ foam core enable efficient mass production of multicopter drone blades and fixed-wing drone wings.
