Medical-grade biocompatible injection molding materials-AbleMed

塑料原料 (3)

Medical-grade biocompatible injection molding materials are special engineering plastics used in the manufacture of medical devices and components. These materials do not cause allergic or rejection reactions when in contact with or inside the human body. They are commonly used to produce surgical instruments, implants, and various medical equipment. All biocompatible materials undergo rigorous testing and verification, such as cytotoxicity tests, skin irritation tests, and sensitization tests. They do not release harmful substances and are non-toxic to human cells and tissues. The excellent biocompatibility is a crucial factor in the selection of materials for medical devices.

Characteristics of Biocompatible Medical-Grade Plastics and Materials

Polyether Ether Ketone (PEEK)

High Temperature Resistance: With a melting point of approximately 343°C, PEEK can withstand long-term use in high-temperature environments while maintaining mechanical performance.

Chemical Resistance: Highly resistant to most chemicals, including strong acids and bases.

Wear and Fatigue Resistance: Exceptional wear and fatigue resistance, suitable for high-strength and long-term use scenarios.

Biocompatibility: Non-toxic to human tissues, does not cause allergic reactions or rejection, making it ideal for medical implants.

Good Electrical Insulation: Maintains excellent electrical insulation properties even at high temperatures.

Low Smoke and Low Toxicity: Produces minimal smoke and toxicity when burned, enhancing its suitability for high-safety applications.

Widely used in spinal implants, dental implants, artificial joints, and surgical instruments, frequently applied in medical device components requiring high strength and chemical resistance.

PPSU (Polyphenylsulfone)

Heat Resistance: PPSU exhibits excellent high-temperature resistance, capable of prolonged stability in environments up to 180°C.

Chemical Resistance: It shows outstanding resistance to various chemicals, including strong acids, bases, and common organic solvents.

Superior Mechanical Properties: PPSU features high strength, rigidity, and excellent fatigue resistance, suitable for applications requiring durability and longevity.

Electrical Characteristics: It possesses good electrical insulation properties with high stability and resistance to moisture.

Biocompatibility: Widely used in the medical field due to its excellent biocompatibility with human tissues, minimizing allergic reactions or rejection.

Transparency and UV Resistance: PPSU maintains good transparency and UV resistance, resistant to discoloration and aging.

Impact Resistance: It has high resistance to impact, reducing the risk of fracture or deformation.


PPSU is primarily used in components for medical equipment and devices, such as parts for medical steam sterilizers, components for automated washer-disinfectors, and housings for medical devices like X-ray machines and CT scanners. It is also utilized in handle components for dental treatment equipment, connectors and fittings for medical devices such as infusion pumps and respirators. Additionally, it finds numerous applications in surgical instruments such as components for scalpels, forceps, and scissors.
