Product Description
Kadeswara Healthcare’s dedication to cutting-edge research and development has positioned the company as a leader in manufacturing high-quality crosslinked UHMWPE. This advanced material offers substantial benefits by significantly reducing wear in medical devices, making it an ideal choice for use in implants. The crosslinking process, which exposes standard UHMWPE to ionizing radiation, transforms it into a superior grade of UHMWPE—Crosslinked UHMWPE—providing significant value to both implant manufacturers and patients by enhancing durability and longevity.
The Crosslinking Process of UHMWPE
The process of crosslinking involves subjecting UHMWPE to ionizing radiation, typically using an electron beam or gamma radiation from sources like Cobalt 75kgy. Two critical aspects of this process—dose level and oxidation—must be tightly controlled to achieve optimal results.
Dose Level Control: The radiation dose is crucial because it directly impacts the mechanical strength of the UHMWPE. As the dose increases, the material’s strength tends to decrease, making it essential to maintain precise control over the dose to ensure consistency in both batch production and individual parts.
Oxidation Management: Oxidation occurs as a result of free radicals generated during irradiation. To mitigate oxidation, the material is either annealed or re-melted soon after irradiation. Following this, the outer surface of the UHMWPE rods is removed by a few millimeters to eliminate the oxidized layer, further enhancing the material’s stability.
Ensuring Uniformity in Crosslinking
Through years of development, Kadeswara Healthcare has perfected its crosslinking techniques, achieving tighter control over dose distribution. This ensures greater uniformity in the final product, leading to improved performance and consistency across applications. By partnering with selected vendors for e-beam, gamma, and x-ray crosslinking technologies, Kadeswara offers the capability to produce custom crosslinked UHMWPE variants for OEMs worldwide. These bespoke solutions optimize the material’s performance for various orthopedic applications, meeting the unique demands of different implant designs.
