RPE threading pipe is polyethylene, which is similar to wood in composition and contains only carbon and hydrogen: halogen-free flame retardant is added, non-toxic, even if it decomposes at high temperature, it only releases carbon dioxide and water, and does not cause secondary pollution. The biggest feature of RPE pipe is good toughness, which is a semi-rigid material.

Product Introduction

The main base material of RPE pipe is polyethylene, which is similar to wood in composition and contains only carbon and hydrogen: halogen-free flame retardant is added, non-toxic, and it decomposes at high temperature in time, only releasing carbon dioxide and water, and does not cause secondary pollution. The biggest feature of RPE pipe is good toughness, which is a semi-rigid material and can return to its original state after heavy pressure is evacuated. The operating temperature is from 50буC to minus 30буC. It is not soft at high temperature and not brittle at low temperature.

Application characteristics

It is used in the construction industry as a flame-retardant polyethylene pipe (RPE flame-retardant threading pipe) for wire and cable protection. After years of use by construction units, it is consistently reflected that RPE has the following characteristics:

1. Eliminate air pollution and make residents feel safe. RPE pipes only contain carbon, hydrogen, and flame retardants. They are all inorganic and non-toxic. Even at high temperatures, they can only release carbon dioxide and carbon monoxide, which will not cause environmental pollution.

Second, the construction is convenient and can speed up the progress of the work. PRE pipes are made by adding flame retardants to the original polyethylene pipes (Little White Dragon). It has the characteristics of polyethylene pipes, good high temperature resistance, not soft at high temperatures, not hard or brittle at low temperatures, light material, easy installation, and can speed up the progress of the project.

Third, RPE pipes are cheap and can reduce construction costs. The price of RPE pipes per unit length of the same weight is lower than that of PVC.

Development History

In the 1980s, polymer building materials only focused on fire resistance, and RPE flame retardant technology had not yet been industrialized on a large scale. PVC threading pipes were rapidly promoted by force. First, because most casualties caused by fires were suffocated by toxic smoke and dust, various harmful components in the living space (such as heavy metals in the human body generally exceeded the standard) were everywhere, and the smoke toxicity and heavy metal stabilizers of PVC could not be solved at all. The main base material of RPE threading pipe is polyethylene, which is similar to wood in composition and contains only hydrocarbons. Halogen-free flame retardants are added, which is non-toxic and decomposes promptly at high temperatures, releasing only carbon dioxide and water without causing secondary pollution.
