Colored Rubber and Plastic Insulation Pipe

This Class 1 Grade Colored Rubber and Plastic Insulation Pipe is an upgraded high-performance thermal insulation piping product integrating practical performance and visual design, produced by Hebei Huashuo Xingye Thermal Insulation Building Materials Co., Ltd. Based on the classic rubber and plastic insulation pipe formula, it is added with environmental protection color masterbatch, taking nitrile rubber and polyvinyl chloride as core raw materials, and manufactured through sophisticated processes such as mixing, intensive mixing, extrusion and foaming. The raw materials are fully fused to retain all the excellent performance of the original product, and the added environmental protection color system makes it more in line with the personalized decoration and identification needs of different engineering scenarios. The product has obtained UL GREENGUARD Gold, China Green Product, ROHS and other authoritative certifications, and is produced in strict accordance with the national standard GB/T 17794-2021, ensuring both environmental protection, safety and standardized production, and the color is non-fading, non-toxic and harmless, meeting the high standards of engineering use.

It inherits the outstanding thermal insulation performance of the classic series: the thermal conductivity is ≤0.030W/(m·K) at 0℃ and ≤0.031W/(m·K) at -20℃, and the thermal conductivity ranges from 0.029 to 0.033W/(m·K) in the range of -20℃ to 25℃, which can effectively reduce heat transfer and realize efficient and stable thermal insulation for piping systems. The applicable temperature range is as wide as -50℃ to 110℃, which can maintain reliable adiabatic performance even in extreme cold environments, adapting to the thermal insulation needs of various temperature working conditions. In terms of safety and flame retardancy, it meets the B1 grade combustion performance standard, with an oxygen index of ≥32% (actual tested up to 42.0%) and a smoke density of only 46 (≤75). It has the characteristics of self-extinguishing without dripping fire after leaving the fire source, with 0s continuous combustion time and low temperature rise in furnace tests, which can effectively reduce the fire risk of the piping system and provide strong safety protection for personnel and property.

Adopting a closed-cell structure, the product has excellent and long-lasting moisture-proof performance: the moisture resistance factor is ≥10000, the water vapor transmission coefficient is ≤2.8×10⁻¹¹g/(m·s·pa) (actual tested 9.40×10⁻¹²g/(m·s·Pa)), and the vacuum volume water absorption rate is only 0.23%. This structure can effectively block water vapor penetration, keep the interior of the pipe dry for a long time, avoid performance degradation caused by moisture erosion, and greatly extend the service life. At the same time, the color layer is closely combined with the insulation base material, with strong scratch resistance and wear resistance, and the color can remain bright and uniform for a long time even in harsh use environments such as humidity and high temperature. It also has the advantages of good flexibility and easy construction: excellent elasticity and shock absorption performance can make it perfectly fit curved or irregular pipe sections; it is easy to cut and splice according to construction needs, no additional vapor barrier is required during installation, which reduces construction cost and difficulty, and the pipe can be reused after maintenance, improving material utilization rate.

In addition to the core performance, it has a variety of practical additional advantages: good sound insulation and noise reduction effect can effectively reduce the noise generated by fluid flow in the pipe, suitable for noise-sensitive places such as hotels, schools and residential buildings; excellent anti-aging performance, no cracks or deformation after 150h anti-aging test, and resistance to ozone, acid and alkali erosion, maintaining stable performance in industrial and outdoor harsh environments; no skin irritation, can prevent mold growth, and effectively protect the inner pipe from corrosion, ensuring the long-term normal operation of the entire piping system. In terms of specifications, it is consistent with the classic series, with an inner diameter of 6-108mm, a wall thickness of 10-50mm and a length of 1800-2000mm, with a variety of color options to meet the diversified needs of different projects. The surface is flat without defects, the size deviation is strictly controlled, and the compressive rebound rate reaches 83%, with excellent mechanical strength and durability.

This colored insulation pipe is widely used in core fields such as HVAC pipes in buildings, hotels, schools and transportation hubs, cold and hot medium transmission pipes, industrial equipment adiabatic piping, and insulation piping for ships, chemical industry and agricultural facilities. It not only provides efficient thermal insulation, safety and flame retardancy for the piping system, but also can realize color coding and identification of different pipelines (such as cold water, hot water, heating pipelines), making the pipeline layout more clear and standardized, and also meeting the personalized decoration needs of modern engineering. It is a high-quality insulation solution integrating practicality, safety and aesthetics.
