Medical Plastic Injection Molding Materials
pp
Polypropylene is very much in demand in medical injection molding because it has very good chemical resistance, toughness, and compatibility with the majority of methods for sterilization. It is also used to make syringes, vials, and specimen bottles that should be autoclaved. For instance, PP is commonly used to make medical syringes and specimen cups because they are chemical-resistant and durable.
- Mill Lead Time: Up to 3 weeks
- Color: Natural, white, black
PE
Polyethylene is most suitable for plastic injection molding in the medical industry due to its superior chemical resistance, flexibility, and biocompatibility. It is particularly well-suited to produce products like tubing, bottles, and containers which need to be able to survive sterilization procedures. PE finds widespread application in the medical industry in medical packaging, surgical drapes, and blood bags. One of the best applications of PE is for the production of blood storage bags, which have to be flexible and resistant to corrosive chemicals.
- Mill Lead Time: Up to 3 weeks
- Color: Natural, white, black
ABS
Acrylonitrile Butadiene Styrene (ABS) is a generic-purpose thermoplastic resin that is produced by emulsion. It is chemically resistant to corrosion and is widely used in motor vehicle parts, toys, and electronic cases.
It is easy to machine and possesses a relatively low melting point that can easily be molded and formed. Its resistance to impact is high, and therefore suitable for applications that incur high stress or impact. These are the unique properties of ABS and thus find extensive applications on the global platform in various industries.
Common applications: Enclosures
PC
Polycarbonate is also used in medical plastic injection molding due to its shock resistance, transparency, and gamma radiation sterilization compatibility. Polycarbonate is used for the manufacture of handles of surgical instruments, blood oxygenators, and similar components of medical devices. For example, PC is used extensively for surgical instrument applications requiring ruggedness and transparency, e.g., endoscopes.
- Mill Lead Time: Up to 3 weeks
- Color: Clear, transparent
PSU
Polysulfone’s mechanical properties and heat resistance make it a suitable material for medical plastic injection molding. Polysulfone is commonly used for components that must be sterilized over and over again. PSU, for example, is commonly used for components used in dialysis machines and handle components of surgical tools due to heat resistance.
- Mill Lead Time: Up to 4 weeks
- Color: Transparent amber
PET
PET finds extensive usage for plastic injection molding for medical purposes due to its favorable strength, chemical resistance, and transparency. It finds special application in products requiring transparent packaging or hard barriers. For example, PET is used in the production of diagnostic test kits and medical packages where clarity and hardness are crucial.
- Mill Lead Time: Up to 3 weeks
- Color: Clear, transparent
PEEK
PEEK is also found to be extremely significant in medical plastic injection molding due to high mechanical properties, chemical resistance, and biocompatibility. It is used where high performance is required, such as sterilization compatibility, such as surgical devices and implantable medical devices. For example, PEEK is extensively utilized in spinal implants due to high strength and its ability to bear severe medical conditions.
- Mill Lead Time: Up to 4 weeks
- Color: Natural (tan), black
TPE
Thermoplastic Elastomers retain the rubber’s flexibility and also offer the advantage of easy processing of plastics and are thus best for soft-touch parts. TPE is also commonly used in medical devices required to be flexible, such as syringe plunger seals. TPE finds its application in flexible grips and seals in medical devices, where comfort and softness are a requirement.
- Mill Lead Time: Up to 3 weeks
- Color: Various, depending on requirements
LSR
Flexible character, biocompatibility, and thermal stability of Liquid Silicone Rubber make it a suitable candidate for medical plastic injection molding. It is widely applied in the production of products required to be soft but resilient, such as gaskets and seals. For example, LSR is commonly applied in the production of baby care products, such as pacifiers, because of its soft character and high safety levels.
- Mill Lead Time: Up to 4 weeks
- Color: Translucent, can be pigmented
