What are the properties of polyimide?
Properties
- High tensile strength over a wide temperature range of about -270°C to + 300°C.
- High compression strength and high pressure and creep resistance.
- Excellent resistance to wear under high pressure and sliding speeds.
- Excellent resistance to stress cracking.
- Good cold temperature properties.
What is biocompatible plastic?
What is biocompatibility? Biocompatible plastics enhance healing functions without causing toxic or allergic reactions. They’re able to do so because of their chemical inertness; they don’t interact with the environment of the human body, enabling the body to accept these devices without ill effect.
What is high biocompatibility?
2.1 Biocompatibility. Biocompatibility is the ability of an implant material to function in vivo without eliciting detrimental local or systemic responses in the body. 8. Prior to their use in human fracture fixation, biomaterials undergo tissue and animal testing to determine their safety and efficacy.
Is polyimide a nylon?
Polyamides are synthesized by the polymerization between diamines and dicarboxylic acid. Polyimides are synthesized by the polymerization between dianhydride and diisocyanate or diamine. Common trade names are Nylon and Kelvar. The common trade name is Kapton.
What are medical grade plastics?
Medical grade plastic is high wear, temperature resistant and corrosion resistant taking in to account performance after frequent sterilization cycles. Medical Grade Plastic is used in manufacturing many types of medical devices and equipment from MRI machines to diagnostic wands as well as medical and surgical tubing.
Is polyimide a polyester?
The main difference between polyester and polyamide is that polyester is the name of a specific fabric, while polyamide is the name of a particular fabric group. You’ll find both of these fabrics used to make sportswear and other types of clothing, but the two fabrics behave differently in certain aspects.
Is polyimide a Nylon?
What kind of plastic is used in hospitals?
The most widely used plastic material in medical applications is PVC followed by PE, PP, PS and PET. PVC most widely used in pre-sterilized single use medical applications. It is a versatile plastic that has been used in medical applications for over 50 years.
What is the most biocompatible materials and why?
Most biocompatible material is Titanium as it possess very good strength and low density value.
What is biodegradable and biocompatible polymers?
Biocompatible and biodegradable fusion polymers are a class of new generation of biomaterials that have demonstrated great potential for medical devices, tissue engineering scaffolds, drug delivery and biomedical-healthcare sensors.
What is ISO 10993-5?
ISO 10993-5:2009 describes test methods to assess the in vitrocytotoxicity of medical devices. These methods specify the incubation of cultured cells in contact with a device and/or extracts of a device either directly or through diffusion.
What are ISO 10993 and FDA g95-1?
The international standards compiled as ISO 10993, and the FDA blue book memorandum (#G95-1) that is based on 10993-1, address the critical issue of ensuring device biocompatibility by identifying several types of tests for use in selecting device materials.
What is the ISO 10993-1 standard?
The ISO 10993-1 standard, “Guidance on the Selection of Tests,” considers these tests so important that they are prescribed for every type of medical device, along with sensitization and irritation testing.
What is polyimide?
Polyimide (sometimes abbreviated PI) is a polymer of imide monomers belonging to the class of high performance plastics. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles.
