What kind of flameproof bellows have what characteristics？

Plastic corrugated pipe is a kind of all-plastic single-wall corrugated pipe which is used to wear wire. It is a very light wire and casing. There are three kinds of PE,PP,PA materials in common looking bellows, and the bellows produced by these three materials can be divided into two types. Flame retardant and non-flame retardant, what are the flame retardant plastic bellows today? And what are the characteristics of the flame retardant plastic bellows in two different materials:

1, PP flame retardant bellows

PP flame retardant plastic bellows, flame retardant grade up to vO grade, using environmentally-friendly new PP polypropylene material production, more rigid than PE plastic bellows, stronger pressure resistance, the operating temperature:-30 ~ 100 °short time up to 140 ℃ C, the use temperature:-30 ~ 100 °short time up to 140 ℃ C, the use temperature:-30 ~ 100 °short time up to 140 ℃ C, The structure of the bellows is internal and external, most customers will buy black bellows, of course, the production of grey and orange, PP flame retardant plastic corrugated tube flexibility, surface luster, and so on, the most customers will buy black look-out bellows, of course, also produce grey and orange, flame-retardant plastic corrugated tubes have good flexibility and surface gloss. Chemical corrosion resistance, mainly used for automotive wiring, but also for machine tool machinery, automatic instruments, motor motors, protection cable electricity The wire is not subjected to external force wear and insulation. Among the three expected bellows, the PP material is one of the economic problems.

2, flame retardant PA nylon bellows

PA nylon bellows split and flame retardant two kinds, usually no special requirements, the sale of nylon bellows are ordinary non-flame retardant, and most of the spot is also non-flame retardant pipe, flame retardant nylon bellows will be a small number of spot, It's basically a customer order now. Compared to the three kinds of plastic bellows, PA nylon pipe is more expensive, of course, better performance, and high temperature resistance, can be used in-40 °C ~ 125 °C, short-time 150 °C, the use of the pipe is more expensive, but also has a higher temperature resistance, it can be used at-40 °C to 125 °C for a short period of time. Flame retardant nylon hose is based on the material of ordinary nylon hose to add flame retardant to achieve grade Effect. Flame retardant nylon bellows have good flexibility and resistance to distortions, good bending properties, acid resistance, rundown oil, coolant, etc., with bright surface and friction resistance. Load-carrying capacity: can withstand foot pressure does not break and deformation, can recover quickly and without any damage itself, mainly used in mechanical manufacturing, electrical protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, and so on, can be used in mechanical manufacturing, electrical protection, lighting equipment, automobile manufacturing, aviation equipment subway, train, etc. Automation control and other industries.
