Plastic Part Machining in the Medical IndustryPlastic Part Machining in the Medical Industry

Preferred Plastics for the Medical Industry:

Medical plastic part designers and manufacturers seek the expertise at PMI when they are working with high-performance engineering thermoplastics that must survive autoclaving and other sterilization methods.

Plastic part materials can be sterilized hundreds of times without degradation. Plastics are becoming more prevalent on a daily basis in major surgeries as well as routine medical procedures in the form replacement joints, various supports, therapy and diagnostic equipment.

Radel R Plastic Part Machining

is an extruded form of polyphenylsulfone (PPSU) that offers higher impact resistance and has superior hydrolysis resistance than other amorphous materials, including both polysulfone and polyetherimide ( PEI). It retains much of the thermal resistance, stability, and machinability of PEI. These properties make it ideal for medical applications requiring autoclaving.

Radel Plastic Part Machining

PES (Polyethersulfone) is a high temperature amorphous thermoplastic offering a superior combination of better chemical resistance and higher dry heat capability than polysulfone (Udel ®) or polyetherimide (Ultem ®). Polyethersulfone may also be referred to as Polyarylsulfone.

Radel ® A PolyEtherSulfone provides a greater margin of performance in such areas as toughness in comparison with other plastics. It has a high heat deflection temperature of 400°F (204°C), good hydrolytic stability, and chemical resistance to many commonly used acids and bases.

Udel Plastic Part Machining

Polysulfone offers high chemical resistance to acidic and salt solutions and good resistance to detergents, hot water and steam. In addition, polysulfone has excellent radiation stability, and offers low ionic impurity levels. Polysulfone often replaces polycarbonate when higher temperatures, improved chemical resistance or autoclavability is required. It is commonly used for analytical instrumentation and medical devices.

Propylux Plastic Part Machining

Medical grade Propylux HS is made from an FDA approved polypropylene resin. Through a unique heat-stabilizing process, the extruded material is able to withstand higher temperatures with less water absorption than standard polypropylene. Recommended sterilization techniques for Propylux HS include steam autoclaving and cold sterilization.

PEEK-LSG Plastic Part Machining

(Life Science Grades), Typical applications for these new materials include machined components for surgical and dental instruments, analytical and monitoring components equipment, X-ray apparatus, anesthetic and therapy components and diagnostic devices. This new product line also delivers a high degree of dimensional stability over a wide temperature range in wet and dry environments. This helps maintain precision tolerances especially important in surgical, exploratory and analytical devices.

Noryl Plastic Part Machining

The shapes are exclusively marketed by Ensinger. Tecanyl MT is destined for the repeated exposure of up to 1000 autoclaving cycles at 134 degrees C, without considerable loss of mechanical properties. The material is excellently suitable for medical device applications, e.g. reusable surgical instruments.

It has good strength and high impact strength and is easily machined.
