RADEL® R-5800 PPSU: Transparent Heat-Resistant Materials
โครงสร้างผลิตภัณฑ์
What is RADEL® R-5800
RADEL® R-5800 is a series of high-performance transparent grades of polyphenylsulfone (PPSU) developed by Solvay. This series combines excellent optical properties, mechanical strength, high-temperature resistance, and flame retardancy, while also offering good dimensional stability and electrical insulation.
It is suitable for high-end applications such as medical devices, food contact components, electrical insulation, and heat-resistant transparent parts.
The RADEL® R-5800 series currently includes the following three grades:
・PPSU R-5800 TR YL551 (yellow transparent tint)
・PPSU R-5800 TR BU501 (blue transparent tint)
・PPSU R-5800 TR VT511 (purple transparent tint)
All three grades share core performance characteristics, differing primarily in their optical appearance and flame retardancy performance at varying thicknesses, providing customers with flexible options based on their design and application scenarios.
01 | จุดเด่นของประสิทธิภาพหลัก
ประสิทธิภาพของออปติคอล
-Refractive index: 1.67 (ASTM D542)
-Transparent grade materials can provide clarity and color design freedom in medical devices and optical components.
-All three models are available in different color versions (yellow, blue, and purple), which are suitable for brand differentiation and product identification.
Mechanical properties
-Tensile strength: approximately 69.6 MPa
-Tensile modulus: 2340 MPa
-Bending strength: 91 MPa
-Impact strength of cantilever beam without notch: 70.4 kJ/m²
👉 combines toughness and rigidity, capable of withstanding high loads and impact scenarios.
Thermal performance
-Heat distortion temperature (1.8MPa) : 207°C
-Glass transition temperature (Tg) : 220°C
-It can remain stable for a long time in high-temperature environments and is not prone to deformation.
Electrical performance
-Volume resistance: 9E+15 Ω·cm
-Insulation strength: 15 KV/mm
👉 is suitable for electrical components that require high insulation.
Flame retardant performance
-UL94 Fire resistance rating: V-0 (full thickness range from 0.25mm to 3mm)
-It meets strict flame retardant standards and is suitable for the safety requirements of industries such as medical care, electronics, and transportation.
02 | Comparison of Model Differences
| แบบอย่าง | Main Color | Flame Retardancy (UL94) | Application Highlights |
| R-5800 TR YL551 | Yellow Transparent | 0.25mm – 3mm all V-0 | Medical device housings, food processing windows, emphasizing warm tone and durability |
| R-5800 TR BU501 | Blue Transparent | 0.25mm – 3mm all V-0 | Electrical components, electronic housings, emphasizing tech sense and insulation performance |
| R-5800 TR VT511 | Violet Transparent | 0.25mm, 1.5mm, 3.0mm V-0 (full color), 0.75mm V-0 | Medical diagnostic equipment, testing instruments, emphasizing differentiated recognition and high heat resistance |
The mechanical and thermal properties of the three materials are almost the same. Purchasers can choose based on color identification, flame-retardant thickness grade and application scenarios.
03 | Typical Application Fields
Medical industry: Surgical instrument casings, reusable sterilizable components, transparent observation Windows
Food processing and catering: High-temperature resistant transparent containers, observation Windows
Electrical and Electronic: Insulating housing, transparent protective cover
อุปกรณ์อุตสาหกรรม : High-temperature resistant transparent parts, flame-retardant structural components
04 | Procurement Suggestions
If you need high transparency and brand color recognition → choose YL551 (yellow), BU501 (blue), VT511 (purple).
If you are concerned about the flame retardant consistency under thickness → YL551 and BU501 are more stable.
If you need a special appearance to distinguish (such as purple for high-end medical equipment) → VT511 is the first choice.
