Polypropylene is a popular medical plastic due to its ability to withstand high temperatures and extreme steam sterilization while maintaining durability. It is recyclable and more cost-effective compared to other medical plastics. Its moldability and resistance to acids, bases, and solvents make it ideal for producing non-absorbable sutures, plastic containers, clear bags, prescription bottles, disposable syringes, connectors, and finger-joint prostheses.

Polyethylene (PE):

Polyethylene is known for its durability, toughness, and cost-effectiveness. Its resistance to impact, chemicals, and moisture absorption makes it perfect for various medical applications. Polyethylene is biologically inert, ensuring it does not harbor harmful organisms, making it suitable for medical implants and devices that can withstand various sterilization techniques and cleaning agents.

Acrylonitrile Butadiene Styrene (ABS):

ABS is a thermoplastic copolymer that serves as an excellent alternative to metal parts in medical devices. It is rigid, durable, and offers an appealing aesthetic quality that can be easily colored. ABS can undergo various molding processes and withstand medical sterilization techniques like gamma radiation or chemical sterilants, making it ideal for non-absorbable sutures, tendon prostheses, tracheal tubes, and drug-delivery systems.

Polyvinyl Chloride (PVC):

PVC is available in different forms, with the most commonly used types in the medical industry being those with high thermal stability, corrosion resistance, and flame-retardant properties. PVC can be molded into rigid or flexible medical parts, depending on the amount of plasticizer added. It is widely used to produce catheters, feeding tubes, and infusion bags for nutrients and dialysis fluids.

Polystyrene (PS):

Polystyrene is widely used in medical applications due to its ease of sterilization and excellent optical properties. It is suitable for manufacturing test tubes, diagnostic tools, Petri dishes, casing for test kits, tissue culture trays, and other medical devices.

Polyethylene Terephthalate Glycol (PETG):

PETG is a transparent, durable, and machinable thermoplastic polymer extensively used in medical applications. It can withstand sterilization procedures, including radiation and liquid chemicals, without degrading. PETG is commonly used for medical food containers and sterilization trays.

Polymethyl Methacrylate (PMMA):

Also known as acrylic, PMMA shares properties similar to glass, such as the ability to reflect and transmit light. These characteristics make it an excellent choice for fabricating endoscopic implants and other medical devices requiring optical clarity.

These plastics are part of a broader category known as thermoplastic materials, which are essential in manufacturing a variety of medical applications due to their versatility and ease of processing.
