Introduction

With the advancement of science and technology and the development of social economy, the application of new materials has become an important force to promote the development of all walks of life. Among the many engineering materials, glass fiber products are favored due to their excellent performance. Among them, glass fiber needle felt and glass fiber high silica needle felt, as two common thermal insulation materials, play an important role in different application scenarios.

What is fiberglass needle felt?

Fiberglass needle mat is a special insulating material made of glass fiber. During the production process, we use barbed needles to mechanically interlock individual glass fibers, which helps to form a porous and flexible mat structure with a high degree of uniformity and consistency. In addition, the felt can be further customized by changing the fiber diameter, density and thickness according to specific application requirements. The fiberglass needle felt produced by Yu Niu has excellent thermal insulation, sound absorption, mechanical strength and other properties, and is widely used in electrical equipment, thermal insulation, heat insulation, automotive industry, etc.

What is fiberglass high silica needle felt?

Unlike ordinary fiberglass needle felt, Yu Niu fiberglass high silica needle mat uses fine E glass fibers and is made by a needle felt production machine. The tiny gaps formed during the production process give the product excellent thermal insulation properties. The insulation and electrical properties of binder-free E glass make high silica needle felt an excellent environmentally friendly product in the field of insulation materials.

How to choose fiberglass needle felt and high silica needle felt?

In the process of engineering design and construction, the rational selection of suitable materials is crucial to the success of the project. Whether it is applied in construction, industry or other fields, the choice of materials is directly related to the performance, service life and safety of the final product. As two common thermal insulation materials, fiberglass needle felt and insulation high silica needle mat have their own advantages in different application scenarios. Therefore, it is very important for you to understand the difference between them and make reasonable material selection decisions based on this.

Clear application requirements

• Working environment: Understand the working environment of the material, including natural conditions such as temperature, humidity, pressure, light, and whether there are corrosive or abrasive media.

• Performance requirements: Determine the specific performance indicators that the material needs to meet, such as strength, toughness, heat resistance, corrosion resistance, conductivity, etc.

• Safety standards: Understand the relevant safety standards and regulatory requirements to ensure that the selected materials meet national or industry standards.

Performance comparison

• Temperature resistance: If the application environment temperature is high, such as an industrial furnace, high silica needle felt with strong high temperature resistance should be given priority as the lining material.

• Chemical stability: Consider whether the material will react or degrade in a specific chemical environment. For example, when constructing exterior wall insulation, you need to consider the material's durability and environmental adaptability.

• Mechanical strength: Select materials with sufficient strength based on the load requirements of the application. You need to analyze the material's mechanical properties such as tensile strength, compressive strength, and shear strength.                  

From the perspective of temperature resistance, how to choose fiberglass needle felt and high silica needle felt?

It is crucial to choose the right fiberglass needle felt or fiberglass high silica needle felt. We recommend some key considerations for your selection based on the operating temperature range:

Temperature range assessment

• Determine the temperature range: First, you need to accurately measure and assess the temperature range of the part of the project that needs to be insulated. This includes normal operating temperature, possible peak temperature, and temperature changes under any extreme conditions.

• Consider temperature fluctuations: In addition to the average temperature, you also need to consider temperature fluctuations. If the temperature often changes within a large range, this may affect the choice of material.

Material temperature resistance

• Ordinary fiberglass needle felt: This type of material is generally suitable for working environments with a temperature range of -268°C to +300°C. It performs well in normal and medium temperature environments, with good thermal insulation and chemical stability.

• Fiberglass high silica needle felt: The temperature resistance of this material is far better than that of ordinary fiberglass needle felt, and it can maintain its structure and performance in high temperature environments up to 1000°C. It is suitable for occasions that need to withstand extreme high temperatures. It can maintain its physical and chemical properties for a long time at high temperatures and is not easy to age or deteriorate.

Selection in special circumstances

• Rapid temperature changes: If the temperature in the working environment often changes rapidly, it is recommended to choose glass fiber high silica needle felt because it has better thermal stability and can resist the impact of temperature fluctuations.

• Temporary high temperature: For occasional high temperature conditions, it can be evaluated based on actual needs whether high silica needle felt is needed, or whether other means (such as increased ventilation) can be used to avoid long-term high temperature conditions.

From the perspective of service life, what is the difference between fiberglass needle felt and high silica needle felt?

There are many factors to consider when choosing fiberglass needle felt vs. fiberglass high silica needle felt. Here are the key points to help you make a choice from the perspective of specific application service life:

Automotive industry:

• Ordinary 1500gsm glass fiber needle mat has good chemical stability and is not easily corroded by most chemicals. It has a certain mechanical strength, so it is suitable for sound insulation and heat insulation of automobiles. However, its strength may decrease during long-term use, especially in extreme environments (such as high temperature, humidity, etc.).

•  E-glass high silica needle mat has higher chemical stability and can maintain its performance in a wider range of chemical environments. Due to its special high silica content, the fiber bonding force between high silica needle felt is stronger and the structure is tighter, so it has better mechanical strength and tear resistance. Therefore, it is more practical for high-temperature resistant parts such as automobile exhaust pipes.

Pipeline insulation:

• Compared with high silica needle felt, the price of glass fiber needle felt is more economical and especially suitable for projects with limited budgets. Glass fiber needle felt is usually softer, easy to cut and install, and suitable for pipes of different shapes and sizes.

• Insulation needle mat  can maintain its physical and chemical properties in high-temperature environments up to 1000°C, and is suitable for high-temperature pipe insulation. High silica needle felt has stronger inter-fiber bonding, a tighter structure, better mechanical strength and tear resistance, and is suitable for pipes subject to greater mechanical stress. High silica needle felt maintains its performance in a wider range of chemical environments and is suitable for pipes exposed to corrosive media. It also has a longer service life.

Household appliances:

In the household appliance industry, choosing the right thermal insulation material is essential to improving the energy efficiency of products, extending service life, and ensuring user safety. Glass fiber needle felt and glass fiber high silica needle felt, as two common thermal insulation materials, have their own characteristics in the application of the household appliance industry.

• In ovens and microwave ovens, thermal insulation materials that can withstand high temperatures are required. High silica needle felt, due to its excellent heat resistance and thermal stability, can effectively isolate internal high temperatures, prevent heat loss, and protect the outer shell from high temperatures. In these high-temperature devices, high silica needle felt is a more suitable choice.

• Refrigeration equipment such as refrigerators and air conditioners require the use of thermal insulation materials to maintain low internal temperatures. Glass fiber needle felt is suitable for the thermal insulation layer of these devices due to its good thermal insulation performance and low cost. In these devices, fiberglass needle felt can effectively prevent cold air loss and improve energy efficiency.

• In washing machines and dryers, although there is no extreme high temperature environment involved, thermal insulation materials are needed to improve energy efficiency and ensure safe operation of the equipment. Fiberglass needle felting mat is an ideal choice due to its cost-effectiveness and good thermal insulation properties.
