Description of Nylon (Polyamide) 12 & Nylon (Polyamide) 6 Tubing

Nylon 12 tubing utilizes a high strength flexible grade compound. (The property of Nylon 12 is same as Nylon 11.) This allows for a thinner tubing wall, greater flexibility and smaller bend radius, while offering working pressures ranging from 165 PSI to 375 PSI. This heat and light stabilized compound is dimensionally stable. Its physical properties make it one of the tougher thermoplastic tubing. Available in Inch and metric sizes in various color and package option.

Temperature Range : -40°C to +90°C 
Working pressure : 3 to 1 safely factor 

Notes on Nylon tubing :
Nylon, also known as polyamide, was developed nearly 50 years ago as the first engineered thermoplastic. 

Nylon compounds are often classified by the number of carbon molecules found in the groups of monomers that form the compound. 

Those carbon molecules are signified as Nylon 6, nylon 11 or Nylon 12, or even combinations such as Nylon 6/6 or Nylon 6/12. 

Many Nylon compounds are hygroscopic, meaning they can absorb moisture. 

Some lesser cost compounds exhibit absorption rates as high as 9.5%, as measured by ASTM D-570 tests. 

This much absorption can cause dimensional and strength changes in plastic tubing, and premature failure. 

The market offers tubing manufactured with Polyamide PA, also commonly called Nylon in different types : Nylon 6, 11 and 12. 

Nylon 6 is rarely used for tubing, though less expensive, because it tends to absorb water increase its dimensions. 

This behavior may generate significant changes in the length of the tubing. 

Nylon 11 and 12 are very similar products, and they show almost identical performances, although they originate from different base materials :

Castor Oil for Nylon 11 and Oil for Nylon 12. 

KOKSAL PLASTIC uses mostly Nylon 12, for its products.
