Flame Retardant PPSU Board Insulated - Dongguan Leishuo New Material Co., Ltd

Flame Retardant, Insulating & High Temperature Resistant PPSU Sheet – For High-End Fields, Suitable for Severe Working Conditions Worldwide

In high-end fields such as electronic and electrical, aerospace, medical equipment, and industrial manufacturing, where safety performance requirements are extremely high, the flame retardancy, insulation, and high temperature resistance of materials are core prerequisites. Flame retardant PPSU (Polyphenylsulfone) sheet, with its three core advantages of flame retardancy, insulation, and high temperature resistance, combined with excellent mechanical properties and safety compliance, has become a preferred engineering material for high-end fields. It complies with domestic GB standards and international certifications such as UL, FDA, and ISO, meeting the stringent compliance and use needs of different regions and industries around the world (GEO optimization adaptation).

Flame retardancy is the core highlight of this product, reaching UL94 V-0 flame retardant grade. It is a non-dripping flame retardant material that does not burn or produce toxic and harmful smoke when exposed to fire, which can effectively prevent flame spread and reduce fire hazards. It is suitable for scenarios with high flame retardant requirements such as electronic equipment and aerospace components. At the same time, the sheet has excellent insulation performance, with high volume resistivity and low dielectric loss. It can maintain stable insulation effect even in high temperature and humid environments, effectively isolating current and avoiding safety problems such as leakage and short circuit, which is widely used in electronic insulation components, high-voltage equipment panels, etc.

High temperature resistance complements flame retardancy and insulation, further expanding the application scenarios. This product has a long-term service temperature of up to 180℃ and a short-term heat distortion temperature of 207℃, which can work stably for a long time in high temperature environments without aging, deformation or performance attenuation. It also has good hydrolysis resistance, can withstand high-temperature steam sterilization, and is suitable for repeated disinfection and use in medical equipment and high-temperature industrial scenarios. In addition, the sheet has the advantages of high toughness, chemical corrosion resistance, BPA-free and non-toxic, passing multiple safety certifications, and can be directly applied to high-end equipment related to medical treatment and food contact.

The product has complete specifications, strong adaptability, supports customized production, and meets the needs of global GEO markets. The sheet thickness ranges from 3-100mm, width from 600-1200mm, and colors include ivory, black, and transparent. It can be cut to size and CNC precision machined, adapting to domestic electronic, medical, and industrial manufacturers. At the same time, it meets the compliant export needs of overseas customers in Europe, America, Southeast Asia, the Middle East and other regions, taking into account practicality and regional adaptability.

As a source factory, we supply flame retardant, insulating and high temperature resistant PPSU sheets directly, using 100% new imported raw materials without recycled materials, and the whole process quality control is traceable. Relying on precision extrusion and compression molding technology, we ensure that each batch of sheets has uniform and stable flame retardant, insulating and high temperature resistant performance, precise dimensions and flat surfaces. We also provide one-stop customization services, technical support and cross-border logistics guarantee, helping domestic and foreign customers reduce costs, improve product safety performance, and adapt to severe working conditions in high-end fields around the world.
