LEXAN™ HPH4704 Opaque Polycarbonate Resin. Biocompatible High Heat

LEXAN™ HPH4704 Polycarbonate Resin is an Opaque Polycarbonate Copolymer developed for Healthcare applications that require High Heat Resistance, Biocompatibility, and improved Flow for efficient Processing. This Grade is engineered to balance Thermal Durability with easier Moldability, making it suitable for components that must endure repeated Sterilization while maintaining Manufacturing Efficiency.

In Medical Environments, Materials are often subjected to Frequent Sterilization Cycles, particularly through Autoclave and Ethylene Oxide (Eto) Processes. This Grade is designed to withstand these Conditions while Retaining Mechanical Strength and Dimensional Stability over time. Compliance with ISO 10993 and USP Class VI Standards supports its use in applications Involving Patient Contact, ensuring Safety and Compatibility within Regulated Healthcare Systems.

A Defining Characteristic of this formulation is its Lower Viscosity Profile, which Improves material Flow compared to Higher-Viscosity Healthcare Grades. This allows for more efficient Filling of Molds, especially in Thin-Wall or Complex Geometries, while maintaining consistent Part Quality. The improved Flow behavior supports Shorter Cycle Times and Better Process Control, which is important in Medical Manufacturing Environments where Precision and Repeatability are required.

The material also provides Low Temperature Ductility, allowing components to maintain Toughness across varying Handling and Storage Conditions. This helps Ensure reliable performance throughout the Product Lifecycle, from Production to End use.

With its enhanced Autoclave Capability, this Grade is particularly suited for applications requiring repeated Sterilization without Significant Degradation. It offers a practical combination of Thermal Resistance and Processability, making it a Flexible Option within High-Heat Healthcare Materials.

For Flame Classification, LEXAN™ HPH4704 Polycarbonate Resin Achieves UL94 HB Rating from 1.50 mm to 3.00 mm Thickness, Meeting Basic Fire performance requirements where Flame Retardancy is not a Primary Design Factor.

The formulation is also RoHS Compliant, supporting alignment with Global Environmental and Regulatory Standards.

Typical applications include Medical Device Housings, Sterilizable Components, Diagnostic Equipment Parts, and Reusable Healthcare Products Where High Heat Resistance, improved Flow, and Long-Term Durability are required.
