A bead made by foaming modified PPE resin and have excellent flame resistance, low dielectric properties, dimensional accuracy.
A foam material that combines flame resistance, thermal insulation, water resistance, heat resistance, and high design flexibility
What is SunForce™?
SunForce™ is a particle foam made from modified PPE resin, XYRON™. It combines the unique properties of modified PPE—such as heat resistance, dimensional stability, low water absorption, and hydrolysis resistance—with the advantages of bead foam, including light weight and excellent moldability (design flexibility). Thanks to its outstanding flame retardancy and heat resistance, SunForce™ achieves UL94 V-0 certification, offering a rare balance of safety and performance in a foam material.
SunForce™ also offers excellent productivity through in-mold foaming, making it ideal for mass production. In addition, its closed-cell structure provides outstanding thermal insulation performance.
Application 1: Energy Savings and Lower Utility Costs Through Insulation in High-Temperature, High-Humidity Environments Such as Washer-Dryers
SunForce™ maintains stable mechanical strength and dimensional stability even under high-temperature, high-humidity conditions found in washer-dryers, making it ideal for the mass production of high-performance insulation materials. Its excellent flame retardancy (UL94 V-0) also makes it suitable for placement around electrical connection points in home appliances and electronic devices.
In a demonstration test using a drum-type washer-dryer, as shown below, SunForce™'s superior thermal insulation enabled a 15.3% reduction in the power required to maintain internal drum temperature during the drying cycle—contributing significantly to energy efficiency.
By leveraging this energy-saving performance, SunForce™ thermal insulation can be applied to commercial equipment such as coin-operated laundry machines, where it is expected to improve energy efficiency during the drying process. This may lead to benefits such as reduced utility costs for both owners and end users.
Our download materials provide further details on the above demonstration test, as well as simulation data from CAE analysis under dryer-like conditions, highlighting the energy-saving potential of SunForce™.
Application 2: Balancing Energy Efficiency and Safety in HVAC, Refrigeration, and Freezing Equipment Using Low-GWP Refrigerants
To reduce environmental impact, a global shift toward low-GWP refrigerants is underway in air conditioning, refrigeration, and freezing equipment. *¹ However, many of these refrigerants are highly flammable, posing new safety challenges.
In response to this, the international standard UL 60335-2-40 for electrical appliances was revised in 2022 to include enhanced safety requirements related to refrigerant flammability in heat pump systems.*²
Similarly, UL 60335-2-24, the standard for refrigeration and freezing appliances, requires the use of insulation materials that meet the UL94 5VA flame-retardant rating.*³

SunForce™ features excellent flame retardancy with UL94 V-0 certification (self-extinguishing performance), and complies with the polymer material requirements around electrical connection points as defined in UL 60335-2-40 for heat pumps, air conditioners, and dehumidifiers.
In addition, SunForce™ has been confirmed to exhibit performance equivalent to UL94 5VA certification. This suggests its strong potential to meet the flame-retardant requirements for insulation materials as specified in UL 60335-2-24 for refrigeration and freezing equipment.
By using SunForce™ as an insulation material in HVAC, refrigeration, and freezing equipment, it not only contributes to energy savings and condensation prevention through effective thermal insulation, but also enhances safety when flammable refrigerants are used.
