Plastic tubing, with its excellent combination of price, durability, chemical resistance, abrasion resistance, and flexibility, makes it a workhorse product in the market. Plastic is preferred over other materials in an array of tubing applications, such as smoke evacuation tubing, irrigation, fluid transfer, IV lines as well as insufflation tubing. Certain specifications are used to decide which thermoplastic fits the requirements perfectly. They are:
- Pressure rating
Pressure rating is defined for fluid flow applications where which material is to be used is decided by comparing the minimum and maximum pressure that the tube can withstand. Keeping the requirement in mind, a decision is made after measuring the pressure in pounds per square inch(psi).
- Minimum bend radius
Flexibility plays a major role in plastic extrusion. This is why the maximum bend radius is calculated and compared to find out the amount of deformation the cross-section can undergo.
- Range of temperature
Here, the specific range of ambient as well as harsh temperatures are compared, and the one that best suits the client’s requirements is picked.
- Maximum vacuum
This refers to the maximum amount of vacuum that can be created in a tube at a time. This is generally calculated in millimetres of mercury.
