Leishuo New Materials specializes in R&D and customization of medical-grade PPSU sheets. Based on in-depth expertise in polyphenylsulfone (PPSU) materials, we create high-performance sheet products for the medical field, with excellent biocompatibility as the core advantage, meeting the strict safety and stability requirements of medical devices for materials.
As a non-toxic amorphous thermoplastic material free of bisphenol A, medical-grade PPSU has passed ISO10993 biocompatibility standards and FDA food contact material certification, suitable for medical scenarios involving indirect contact with human tissues and body fluids. The sheets also possess outstanding properties: heat distortion temperature up to 207℃, capable of withstanding over 1,000 cycles of 134℃ steam sterilization without significant performance degradation.
It also has good hydrolytic stability, chemical corrosion resistance and impact strength, able to withstand cleaning with common medical disinfectants without chemical changes. In terms of specification customization, it supports the customization of conventional sheets with a thickness of 2mm to 50mm, can be cut into different sizes on demand, offers color options such as amber, transparent and black, and the surface finish can be optimized according to device needs, suitable for medical disinfection boxes, instrument trays, ventilator components and other scenarios.
Leishuo has built an exclusive one-stop service for medical-grade materials, with independent control over the entire process from the selection of compliant raw materials, suggestions on biocompatibility performance adaptation, to precision extrusion molding, surface treatment and finished product testing. Each batch of sheets is accompanied by a material test report to ensure that indicators such as biocompatibility and purity meet standards, and the materials are traceable, reducing application risks in the medical field. The professional team can provide optimization plans based on device structure needs to improve product adaptability.
