SunForce™ is a foamed bead made from Asahi Kasei 's modified PPE resin "XYRON™". This page introduces "SunForce™ BE," a product in the SunForce™ product lineup that has particularly excellent flame resistance.
SunForce™ BE is a highly functional material with unprecedented design possibilities.In addition to the unique performance of this lightweight thermal-insulating foam, the flame-retardant qualities, dimensional accuracy, and thin-wall molding of the material combine functions beyond those of conventional foams to facilitate a wide range of design proposals in line with the requirements for product and component design.
We can make a wide range of proposals to meet your product and component design needs.
SunForce™ BE has the unique performance of foam, such as light weight and heat insulation, and also has functions beyond those of conventional foam, such as flame resistance, dimensional accuracy, and thin-wall molding, making products lighter and more functional.
SunForce™ BE is a foam-bead material to achieve compliance with the V-0 level of the UL-94 flame-retardant standard for plastic components, indicating an extremely high level of flame retardance.As shown below, UL 94 V-0 is achieved when specimen self-extinguishes within 10 seconds and drips of particles are not inflamed.
SunForce™ BE has superior heat resistance compared to conventional foamed plastics. PPE, the raw material for SunForce™ BE, is an engineering plastic that has excellent heat resistance among plastics, and SunForce™ BE inherits this characteristic.
*As a separate grade, SunForce™ BH (high heat resistant product) is available. Composite forming with various materials such as carbon-fiber-reinforced plastics (CFRP) enables the production of lightweight, high-strength, heat-insulating, flame-retardant, and tangible composites. Please contact us for details.
SunForce™ BE is a material made by foaming modified PPE resin with low dielectric properties, and therefore has extremely low dielectric properties. This allows for low electromagnetic wave attenuation at high frequencies.
SunForce™ BE has a low thermal conductivity compared to other materials and is a high-level insulation material. SunForce™ BE can be applied to applications requiring thermal insulation, warmth, and condensation prevention.
SunForce™ can be molded into thin walls, which is difficult to do with conventional foams, and has shock absorbing properties, so it can contribute to space-saving and weight reduction of products and parts.
Although it is a foam, it can also be used for parts with thin ribs or thin shapes.
As described above, the dimensional change at the time of fabrication is also very small, and molding at a level similar to ordinary injection molded products is possible.SunForce™ can be used with confidence in structures requiring dimensional accuracy.
In addition, SunForce™ BE inherits the characteristics of PPE resin, which has a low coefficient of linear expansion in comparison with other plastics, and the effects of temperature are relatively small.
In addition, when molding SunForce™ BE, warpage and sinkage are less likely to occur even when the product incorporates large variation in wall thickness. This allows for freedom in design so that, for example, uniform wall thicknesses are not required. This is because SunForce™ BE employs a method in which the mold is filled with beads which are then expanded and simultaneously fused with the heat from steam.
SunForce™ BE has a very fine bubble structure inside, making it a very light material compared to other materials. (5x foamed product: 0.20g/cc, 7x foamed product: 0.14g/cc, 10x foamed product: 0.10g/cc)
SunForce™ BE's Flame retardance (UL 94 V-0), light weight, and shock absorbing properties are utilized to contribute to the enhancement of lithium-ion battery parts functionality.
By placing SunForce™ BE, which has high thermal insulation and low dielectric properties, on the back of a millimeter wave radar radome, it becomes possible to effectively utilize the heat generated by the heater while suppressing the attenuation of millimeter wave electromagnetic waves.
