Specific use and weight calculation of PTFE rod and its technical parameters Nov 21, 2018

The PTFE rod, like the PTFE tube and the PTFE board, is a material of polyethylene tetrafluoroethylene in the raw material, but it is different in shape and use. Based on this, it is necessary to familiarize yourself with and understand the PTFE rod so that it is well distinguished from the PTFE tube and the PTFE board.

 

1. When purchasing a PTFE rod, is there a requirement in the manufacturer's choice?

When purchasing a PTFE rod, there are some requirements in the choice of its manufacturer. The important point is to choose a professional and regular manufacturer, because it can guarantee the product quality and product performance, if the product is in use. If problems occur, they can be resolved in time to avoid affecting the normal use of the product. Therefore, this specific requirement should be strictly enforced and cannot be sloppy.

 

2. What are the specific applications of PTFE rod?

Chemical field: It can be used as anti-corrosion parts, and it can also be used in chemical equipment because it has very good corrosion resistance.

Mechanical field: It can be used as self-lubricating bearing, piston ring, etc. to reduce wear and heat of the machine and reduce power consumption.

Electronics and electrical fields: mainly used in wire and cable and batteries.

Medical field: It can be used on a variety of medical devices and can be used as a sealing and filling material.

 

3. Technical parameters and specific specifications of PTFE rod

The technical parameters of the PTFE rod are eight parameters of density, bending strength, tensile strength, friction coefficient, water absorption, dielectric strength, use temperature and melting temperature. In terms of specific specifications, the PTFE is pressed. Rods, extruded PTFE rods and molded PTFE rods. The PTFE rod with a diameter of 4-9mm is used to push the PTFE rod. The PTFE rod with a diameter of 10-50mm is an extruded PTFE rod with a diameter of 55- The 300 mm PTFE rod is a molded PTFE rod. In addition, if the roundness and height are not high, the molded PTFE rod is generally used; if the roundness is high and the height is required to be more than 300 mm, it is more suitable to use the extruded PTFE rod.

 

4. Calculation of the weight of PTFE rods and comparison of nylon rods

The weight calculation of the tetrafluororod is a corresponding formula, which is W=F*L*tetrafluoron density*0.001, where L is the length of the PTFE rod, the unit is meter, and F is the cross-sectional area of the PTFE rod. Tetrafluorocarbon rods and nylon rods, which are two different types of bars, and the materials they use are different, so the two rods are very different.
