Material Options

The type of media flowing through a connection can affect the strength, surface appearance, color, and performance of the connection. Some guidelines for the different types of material:

 

Thermoplastics

Acetal
Strong, lightweight and economical, acetal is used for a wide variety of chemical and mechanical components. It offers high strength and rigidity over a broad temperature range, low wear, toughness and resistance to repeated use.
 
ABS
ABS is an economical medical-grade thermoplastic that withstands gamma and e-beam sterilization and is commonly used in medical devices. ABS is an amorphous material with good physical properties and high resistance to chemical attack.
 
Polyamide (Nylon)

Nylon is very resistant to wear and abrasion, has good mechanical properties even at elevated temperatures, low permeability to gases and good chemical resistance.
 
Polysulfone

Polysulfone is a rigid material with excellent strength and good chemical resistance. It withstands repeated sterilization and higher temperatures than other thermoplastics. Polysulfone's high hydrolytic stability allows use in medical applications requiring autoclave and steam sterilization.
 
Polycarbonate

Polycarbonate is transparent, resistant to some chemicals and withstands sterilization. It is commonly used in medical devices and offers impact resistance, outstanding dimensional stability and good optical properties.
 
Polypropylene

Polypropylene is an excellent general purpose resin that is highly resistant to chemical attack from solvents and chemicals in harsh environments. In general, polypropylene is resistant to environmental stress cracking and it can be exposed to challenging environments.
 
Polyethylene

Polyethylene is a low-cost, chemically resistant thermoplastic. It is opaque, and can withstand moderately high temperatures. Polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions.
 
PEEK (Polyetheretherketon)
PEEK is a highly temperature resistant, engineered thermoplastic with excellent chemical and fatigue resistance. It exhibits superior mechanical and electrical properties.

 
PPS (Polyethylene Sulfide)
 
PPS offers the broadest resistance to chemicals for its market as an advanced engineering plastic. (PEEK and PTFE have better resistance, but are not considered engineering resins).
 


Fluoropolymers

PVDF
PVDF is a tough engineering thermoplastic with a balance of physical and chemical properties that qualify it for high performance in a wide range of applications. It is mechanically strong, has good ductility, and has a broad temperature range.
 
PTFE
PTFE is chemically resistant to all chemicals and solvents with the exception of some molten metals, molten sodium hydroxide, elemental fluorine, and certain fluorinating agents. PTFE offers chemical resistance and stability at high temperature.
 


Alloys

Chrome-plated Brass Rugged metallic material with an attractive appearance, chrome-plated brass is excellent in applications requiring higher pressure and temperature.
 
Die-cast Zinc Zinc is a durable and lightweight (about 20% less than comparable brass) material that withstands high pressure and temperature.
 

Aluminum
 

Lightweight metal with an available hard anodized finish for durability, aluminum is non-toxic, non-magnetic and non-sparking and is known for its high strength to weight ratio.
