Applications Of Polymers

Modern healthcare would not be conceivable without the use of polymer or plastic materials. Plastics or Polymers have been put in place to make less painful health treatments, from the case of an open MRI scanner to the smallest tubing.

Things we use every day, such as disposable syringes, intravenous blood bags, and heart valves, are now consisting of plastic.

Choosing the right health – care plastic for a medical device or component is a vital step in creating the optimal part. Such tools have become a crucial and important component of the modern health service.

Plastic containers are useful for medical applications due to their excellent barrier qualities, lightweight, low cost, sturdiness, and clarity.  Today’s most creative medical procedures are using plastic materials. Metals, glass, and ceramics were relevant provisions for biomedical devices, devices, and supports.

Polymers, on the other hand, are best suitable for these applications since they are lighter in weight, have higher bioactivity, and are less expensive.

Impressive operations of different polymers in the healthcare field

A large range of medical plastic items is available on a variety of devices. From bottles and beakers for testing through surgical devices, catheters, and implants. Plastics are becoming increasingly popular due to their great efficiency, lightness, and low cost. Equally crucial, healthcare plastic materials should comply with international regulatory standards.

Polymer for medical devices are typically built of thermoplastic materials to assure the plastic material’s safety and effectiveness for medical items. There are regular, crystalline patches among the random polymer chains in semi-crystalline materials.

Crystallization, the creation of these areas during processing, causes polymer shrinkage. It also produces less consistent shrinkage, which might also result in the deformation of a moldable object.

Thermoplastics account for 90 percent of all plastic in use globally in terms of weight. Unlike most thermoset plastics, thermoplastics may be treated without significant property loss. The following are some of the most common use thermoplastics in the medical product molding process;

  • Polycarbonates 

Polycarbonate is a naturally translucent material that provides high UV protection. It is a decent substitute for glass because it is generally shatterproof. Polycarbonate has a remarkable mix of strength, stiffness, and hardness, which aids in the prevention of potentially fatal material failures.

Furthermore, it has glass-like clarity, which is important in therapeutic and diagnostic contexts where the vision of cells, blood, and other fluids is necessary.

Because polycarbonates have exceptional heat resistance, they are exceedingly malleable and are molded at room temperature without cracking or breaking. Polycarbonate’s characteristics make it ideal for prototype applications, such as medical equipment.

Polycarbonate has the potential to be sterilized using all major procedures. It involves ethylene oxide (EtO), irradiation (both gamma and electron beam), and steam autoclaving.

Instrument designers recommend polycarbonate as a metal alternative because of its rigidity and robustness. Polycarbonate’s characteristics make it ideal for prototyping applications such as medical equipment.

  • Polypropylene

Polypropylene is one of the materials advancing towards the front lines of the battle. It is useful to develop more valuable and environmentally friendly medical applications.

PP is a semi-crystalline polymer consisting of both amorphous and semi-crystalline areas. It lacks polycarbonate’s heat resistance and structural qualities. Polyester’s impact resistance, polystyrene or polyethylene’s resistance, or the flexibility or soft feel of flexible polyvinyl chloride. 

However, it has an excellent balance of those characteristics. It also has a high level of chemical resistance, a vast and creative supply base, and favorable economics. Polypropylene’s ductile properties include stability for the cycles it is still utilized in addition to resistance to steam sterilization. Its recyclability also makes it an appealing medical-grade plastic.

  • Polyethylene

Polyethylene is a flexible, long-lasting thermoplastic with numerous applications. Its great impact resistance, chemical resistance, and low moisture absorption make it an excellent medical-grade plastic. It does not degrade or harbor harmful microorganisms and is resistant to strong cleansers.

It is frequently in use in medical implants because it is a porous synthetic polymer that is biologically inert and does not break down in the body.

Polyethylene glycol (PEG) is a synthetic, hydrophilic polyether molecule that is biocompatible. It has a wide range of applications, mostly in the medical field, as well as in the chemical and industrial industries.

It is non-volatile, non-toxic, colorless, inactive, and odorless. It’s also extremely soluble in common organic solvents including benzene, carbon tetrachloride, and chloroform. PEG has a wide range of medical applications, and the list is constantly expanding. Its non-toxicity and great solubility make it suitable for a wide range of different pharmacological applications.

  • Polyamide

Polyamide, often known as nylon, is a synthetic thermoplastic polymer. It is frequently in use as a substitute for inferior metals due to its strength, temperature tolerance, and chemical compatibility. Polyamide is an excellent material for CNC machining, injection molding, and 3D printing.

To increase its overall strength, it undergoes conditioning or mixing. Polyamide is a good material to use for areas that are susceptible to a lot of wear and tear. Polyamide is resistant to most chemicals, although it is difficult to mold and costly.

It is, however, one of the most difficult materials to shape. It requires a solid manufacturing plan in place to avoid variances, faults, and unnecessary waste. In most circumstances, polyamide is significantly more expensive. It has a tensile strength of 76 MPa, which is extremely strong (11,000 psi).

  • Polyvinyl Chloride (PVC)

PVC is the softest and most flexible material to utilize for disposable medical devices due to its characteristics. The suppleness of medical gadgets guarantees that they are as comfortable as possible. 

Healthcare practitioners will appreciate the softness of the medical gloves as well. Furthermore, PVC-based medical devices are quiet and prevent smells from escaping, giving further relaxation and hygiene.

PVC is utilized in the production of blood bags and other non-breakable containers, which are essential in today’s healthcare. For this kind of gadget, soft PVC is thought to be the best material. It is light and nearly impossible to rip, making it perfect for the speedy and successful treatment of accident victims.

Conclusion

In conclusion, the main theme of this topic is to provide knowledge about different polymer or plastic materials accessible in the medical field. Medical plastic goods are reshaping the healthcare industry. The growing use of polymer in medical devices has revolutionized the market.

With plastic medical devices steadily displacing other materials such as glass, ceramics, and metals whenever possible. Different manufacturers of medical products like, medical mask manufacturer, medical clothes manufacturers, and other medical manufacturers are very useful. They are giving their services to the medical sector and the medical industry is utilizing these services in order to become safe and healthy.
