1. Plastic casing manufacturers
There are many kinds of materials for plastic sleeves, and the most excellent one is fluoroplastics.
Fluoroplastics consist of fluorine-containing monomers. Monomers such as tetrafluoroethylene, hexafluoropropylene, chlorotrifluoroethylene, vinylidene fluoride and vinyl fluoride are prepared by homopolymerization or copolymerization. With the continuous development of polymer technology, the variety of fluoroplastics is gradually increasing, and the scope of application is expanding.
Due to the fluorine atom contained in the molecular structure of fluoroplastics, it has many excellent properties, such as excellent electrical insulation, high heat resistance, outstanding oil resistance, solvent resistance and abrasion resistance, good moisture resistance and low temperature resistance . Therefore, fluoroplastics occupies an important position in the national defense, electromechanical, metallurgical, petrochemical and other industrial sectors.
In the production of wire and cable, the commonly used fluoroplastics include polytetrafluoroethylene, polyperfluoroethylene propylene, polyvinylidene fluoride, tetrafluoroethylene and ethylene copolymers, etc., which are used to manufacture various heat-resistant and high-temperature insulated wires. ) Well cables, geological exploration cables, heating cables, F-class and H-class motor lead wires, radiation resistant wires, electromagnetic wires, radio frequency coaxial cables, etc.

2. Ptfe bellows manufacturers
Polytetrafluoroethylene (Poly tetra fluoroethylene, abbreviated as PTFE), is generally called "non-stick coating" or "easy to clean material". This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used for lubrication and become an ideal coating for easy cleaning of the inner layer of water pipes.
Ptfe corrugated tube refers to a tubular elastic sensitive element connected by a foldable corrugated sheet along the folding and stretching direction. Bellows are widely used in instruments and meters, and their main purpose is to convert pressure into displacement or force as a measuring element of pressure measuring instruments. The wall of the corrugated tube is thinner, and the sensitivity is high, and the measurement range is from tens of Pa to tens of MPa.
Its open end is fixed, and the sealed end is in a free state, and an auxiliary coil spring or reed is used to increase elasticity. When working, under the action of internal pressure, it stretches along the length of the pipe, causing the movable end to produce a displacement in a certain relationship with the pressure. The movable end drives the pointer to directly indicate the size of the pressure.

Bellows are often combined with displacement sensors to form a pressure sensor that outputs electricity, and is sometimes used as an isolation element. Since the expansion of the bellows requires a large volume change, its response speed is lower than that of the Bourdon tube. The bellows is suitable for measuring low pressure.
