The core value of polyurethane tension agents in thermal insulation material manufacturing: Optimizing thermal insulation effect and reducing material waste

Introduction

Hello everyone! Today we are going to talk about a topic that sounds a bit "high-end" but is actually very down-to-earth - the core value of polyurethane tension agents in the manufacturing of insulation materials. Don’t be scared by the word “polyurethane”, it is actually an important part of the common insulation materials in our daily lives. Today, I will use easy-to-understand language to show you how polyurethane tension agents can optimize thermal insulation, reduce material waste, and even save you money! Ready? Let's get started!

1. What is polyurethane tension agent?

1.1 Basic concepts of polyurethane

First, let’s get to know polyurethane. Polyurethane (PU) is a polymer material that is widely used in construction, furniture, automobiles, footwear and other fields. Its characteristics are lightweight, wear-resistant, corrosion-resistant, and importantly - it has good thermal insulation properties.

1.2 Effect of tension agent

So, what is a tensile agent? Simply put, tensile agent is an additive used to improve the mechanical properties of materials, especially tensile strength and elasticity. In polyurethane materials, the tensile agent acts like a "fitness coach", helping the material become more "stronger" and more "elastic".

1.3 Definition of polyurethane tension agent

Polyurethane tension agent, as the name implies, is a tension agent specially used for polyurethane materials. It improves the tensile strength, elastic modulus and tear resistance of the material by changing the molecular structure of polyurethane, thereby optimizing the overall performance of the insulation material.

2. Application of polyurethane tension agent in thermal insulation materials

2.1 Basic requirements for insulation materials

The main function of thermal insulation materials is to reduce heat transfer and maintain the indoor temperature stable. Therefore, an ideal insulation material needs to have the following characteristics:

Low thermal conductivity: Heat is not easily transferred through the material.
High tensile strength: The material is not easy to break or deform.
Good elasticity: The material can adapt to various shapes and stresses.
Durability: The material can maintain stable performance for a long time.

2.2 How to optimize thermal insulation effect of polyurethane tension agent

Polyurethane tension agent optimizes the insulation effect of insulation materials through the following methods:

2.2.1 Improve the closed porosity of the material

Closed porosity refers to the sealing of the materialThe proportion of pores. The more pores, the lower the thermal conductivity and the better the thermal insulation effect. Polyurethane tensile agents can promote the formation of more closed pores in the polyurethane material, thereby improving thermal insulation performance.

2.2.2 Tensile strength of reinforced materials

Materials with high tensile strength are not prone to breaking, which can better maintain their structural integrity. Polyurethane tensile agents enhance the interaction force between molecules, improve the tensile strength of the material, and ensure that the insulation material is not easily damaged during long-term use.

2.2.3 Improve the elasticity of the material

The elastic materials can better adapt to temperature changes and mechanical stresses, reducing the risk of cracking and deformation. Polyurethane tensile agents improve their elastic modulus by adjusting the molecular structure of the material, making the insulation material more durable.

2.3 How to reduce material waste by polyurethane tension agents

In addition to optimizing thermal insulation, polyurethane tension agents can also help reduce material waste. Specifically, it is implemented in the following ways:

2.3.1 Improve material utilization

Polyurethane tensile agents can improve the processing properties of materials and make them easier to form and cut. This means that during the production process, the material is more utilizing and there is less waste.

2.3.2 Extend the service life of the material

Because polyurethane tensile agent improves the tensile strength and elasticity of the material, the service life of the insulation material is extended. This means that less material needs to be replaced within the same time, thus reducing material waste.

2.3.3 Reduce energy consumption in the production process

Polyurethane tensile agent can optimize the processing technology of materials and reduce energy consumption during production. This not only reduces production costs, but also reduces the negative impact on the environment.

III. Product parameters of polyurethane tension agent

To better understand the performance of polyurethane tensile agent, let’s take a look at its main product parameters. The following is a typical polyurethane tensioner product parameter list:

parameter name	Value Range	Instructions
Density (g/cm³)	0.9 – 1.2	The density of the material affects its weight and strength
Tension Strength (MPa)	10 – 30	The material's large bearing capacity in the stretched state
Modulus of elasticity (MPa)	100 – 500	The stiffness of the material within the elastic deformation range
Thermal conductivity (W/m·K)	0.02 – 0.03	The thermal conductivity of the material, the lower the thermal insulation effect, the better
Closed porosity (%)	90 – 95	The ratio of closed air holes in the material, the higher the heat insulation effect, the better
Service life (years)	20 – 30	The life expectancy of the material under normal use conditions

3.1 Density

Density is the basic physical parameter of a material that affects its weight and strength. The density of polyurethane tensile agents is usually between 0.9 – 1.2 g/cm³, which means it is both light and sturdy and is ideal for use in insulation materials.

3.2 Tensile strength

Tension strength is the material's large bearing capacity in the tensile state. The tensile strength of polyurethane tensile agent is between 10 – 30 MPa, which means it can withstand a large tension and is not prone to breaking.

3.3 Elastic Modulus

The elastic modulus is the stiffness of the material within the elastic deformation range. The elastic modulus of polyurethane tensile agent is between 100 – 500 MPa, which means it has good elasticity and is able to adapt to various shapes and stresses.

3.4 Thermal conductivity

The thermal conductivity is the thermal conductivity of the material, and the lower the heat insulation effect, the better. The thermal conductivity of the polyurethane tensile agent is between 0.02 – 0.03 W/m·K, which means it has excellent thermal insulation properties.

3.5 Coverage rate

The closed pore ratio is the proportion of closed pores in the material, and the higher the heat insulation effect, the better. The closed porosity of polyurethane tensile agent is between 90 – 95%, which means it can effectively reduce heat transfer.

3.6 Service life

The service life is the expected lifespan of the material under normal use conditions. The service life of polyurethane tensile agents is between 20-30 years, which means it can maintain stable performance over the long term and reduce replacement frequency.

4.2.2 Complex processing technology

The processing process of polyurethane tension agents is relatively complex, and it requires precise control of parameters such as temperature, pressure and time. This may increase production difficulty and cost.

4.2.3 Environmental Impact

Although polyurethane tension agents can reduce material waste, some harmful substances may be produced during their production process, which will have a certain impact on the environment. Therefore, appropriate environmental protection measures need to be taken to reduce the negative impact on the environment.

5. Future development trends
