Can polyoxyethylene insulated wire be used as flame retardant wire?

No, regular PVC is not flame retardant. The insulation and sheath materials of ordinary flame retardant wires and cables are generally made of polymer materials containing halogen (or modified by adding halogen-containing flame retardants), and the most commonly used is polyvinyl chloride (PVC) materials. Low-smoke flame retardant wires and cables add inorganic hydroxide flame retardants such as aluminum hydroxide and magnesium hydroxide to the insulation and sheath materials.

Its flame retardant principle is the principle of condensed phase flame retardant: aluminum hydroxide and magnesium hydroxide are decomposed by heat to release water, and at the same time absorb heat to reduce the actual temperature of insulation and sheath materials, inhibit the decomposition of materials and release flammable gases.

PVC insulated wires cannot be used as flame retardant wires.

The flame retardant wire has fire resistance and will not continue to burn away from the source, but the PVC insulated wire does not have such a function.

Ordinary non-flame retardant wire: the so-called ordinary is manufactured by the PVC structure of the early traditional wire, and it is also a common low-end OEM wire in the current market (characterized by poor raw materials and low cost, and its market value is often mistaken for the same as other wire products in a well-known brand OEM, and is shoddy). (Features:.)

Flammable, extremely poor flame retardant, low manufacturing process requirements, characteristics: cheap).

Flame retardant wire: It is a flame retardant product in the current wire brand structure, and flame retardant wire is also the most common name. Flame retardant grades are divided into three kinds of ZA ZB ZC, these three grades of raw materials to distinguish, the flame retardant difference is there, but the flame retardant effect is not obvious.

Even if there is a difference in flame retardant, then they also have a difference in material cost from high to low.

Forts brand flame retardant wire: on the basis of flame retardant performance, halogen elements are used as flame retardants, and the heat reaction produces water, reduces oxygen content and absorbs heat, thereby inhibiting combustion. It is also the wire with the best flame retardant effect in the current flame retardant wire category.

(Flame retardant wires are the most basic wires.)

Hello, the main differences between polyaluminosyl and PVC flame retardant wires are as follows:1The materials are different:

The insulation of polyaluminium vinyl wire is made up of polyethylene and aluminum foil, whereas the insulation of polyvinyl chloride wire is made of polyvinyl chloride material. 2.Flame retardant properties are different:

The flame retardant performance of polyaluminium vinyl wire is better than that of polyvinyl chloride wire, because aluminum foil has good thermal insulation properties, which can effectively prevent fire in the wire. 3.The environmental performance is different:

The environmental performance of polyalumina vinyl wire is better than that of polyvinyl chloride wire, because polyvinyl chloride materials will release harmful substances during production and use, causing harm to the environment and human health. 4.**Different:

The ** of polyaluminium vinyl wire is higher than that of polyvinyl chloride wire, because the cost of aluminum foil material is higher, and the production process of polyaluminium vinyl wire is also more complicated. In short, compared with PVC wire, polyalumina and ethylene wire have better air mode flame retardant performance and environmental protection performance, but it is also higher. When selecting a wire, it is necessary to choose according to the specific use environment and requirements.

It is a halogen-free low-smoke flame retardant fire-resistant cross-linked polyolefin wire, which is composed of 2 cores, and the nominal cross-sectional area of each core is millimeters squared.

The wire and cable representation method is mainly composed of three parts: model, specification and standard number.

For details, please refer to the model number on the surface of the cable or wire. The one with z is generally flame retardant, and the one with n is fire resistant. Irradiated flame retardant wires look denser than ordinary wires, and the feel is different to the touch, and irradiated flame retardant wires are delicate and smooth to the touch, and they look stronger.

It has a higher ampacity than ordinary wires. Eco-friendly, safe and long-lasting.

There are two differences between flame retardant forest fiber wire and non-flame retardant wire (usually fire resistant wire) in principle and structure.

1. The principle is different.

The flame retardant principle of flame retardant wire is to rely on the flame retardant effect of halogen-free lead, and the flame retardant principle of halogen-free cable is to extinguish the fire by reducing the temperature of precipitated water. The non-flame retardant wire relies on the characteristics of the mica material in the refractory layer to ensure that the cable works normally in the event of a fire.

2. The structure is different.

The basic structure of flame retardant cable has the following three points: the insulation layer is made of flame retardant material; The sheath and outer sheath are made of flame retardant materials; Flame retardant materials are used for tape and filling. Non-flame retardant wires generally do not have flame retardant materials, only refractory materials.

From the point of view, the price of flame retardant wires is higher, and the price of ordinary wires is more economical; From the perspective of materials used, flame-retardant wires use materials with good flame retardancy, while ordinary wires use materials with poor flame retardancy; From the perspective of the scope of application, the flame retardant wire has a wide applicability, not only for home decoration, but also for tooling.

Flame retardant wire refers to the fact that in the event of a fire accident, the spread and extension of the flame along the wire can be blocked and delayed, and the extension of the fire range of the wire can be minimized. Moreover, it has the characteristics of self-extinguishing after fire, which can also be understood as that when the wire and cable product catches fire due to itself or an external heat source, the wire will not continue to burn or burn briefly after the fire source subsides.

The use of flame retardant wires: suitable for plastic insulated control wires and electrical equipment with AC rated voltage of 450 750V and below; The scope of application of flame retardant wires is wide, especially for high-temperature and flammable types that require fire resistance, such as power transmission and distribution, control, alarm and fire protection system product lines.

The price of flame retardant wire is higher than that of ordinary wire, and the flame retardant wire uses special flame retardant materials to make its flame retardant performance better, so the flame retardant wire has a wider range of applications, not only for home decoration, but also for tooling.

1.Waterproof, flame retardant, acid and alkali resistant, mothproof, light weight, heat preservation, sound insulation, shock absorption.

2.It is processed on the same level as wood, and the processing performance is far better than that of wood.

3.It is an ideal alternative to wood, aluminum, and composite panels.

As long as it is PVC conduit, it is generally flame retardant, flame retardant and insulation protection are the two characteristics that must exist in the conduit, if the PVC conduit can not be flame retardant and insulation protection, it is a substandard product.

You can ask this question to Suzhou Liansi Electronics, which is very professional in this regard.

Ordinary wires do not extinguish until the insulation burns out, while flame-retardant wire insulation automatically extinguishes within a few seconds! Of course, the specific flame retardant effect depends on the flame retardant level of the wire!
