Research on the application of high resilience castor anti-yellowing agent in office furniture manufacturing

Introduction: From “small casters” to “big wisdom”

In a modern office environment, although casters are an inconspicuous small component, they are the soul of office furniture. Just imagine how much impact our productivity and comfort will be if a chair or table cannot move freely? Among them, the material, performance and service life of the casters directly determine the overall quality of office furniture. However, casters often encounter a problem during use – yellowing. This phenomenon not only affects the appearance of office furniture, but may also reduce its functionality and even shorten its service life.

So, how to solve this problem? The answer is the application of high rebound caster anti-yellowing agent. This is an additive specially used to improve the performance of casters’ materials. It not only effectively prevents casters from yellowing due to factors such as ultraviolet rays and high temperatures, but also improves the elasticity and wear resistance of casters. This article will discuss the characteristics of high-resistance castor anti-yellowing agent, production process optimization and its specific application in office furniture manufacturing, and strive to provide readers with a comprehensive and practical technical guide.

In order to make the content more interesting, this article will be expressed in easy-to-understand language, and appropriately use metaphors and rhetorical techniques to make the originally boring professional knowledge lively. At the same time, we will also compare and analyze the relevant product parameters in the form of a table, and refer to authoritative domestic and foreign documents to ensure the accuracy and authority of the information. Next, let us enter this seemingly ordinary but full of wisdom together!

Basic concepts and classifications of high rebound casters anti-yellowing agent

What is a high rebound caster anti-yellowing agent?

High rebound caster anti-yellowing agent is a functional chemical additive, mainly used to improve the physical properties and weather resistance of caster materials. It can be regarded as the “sunscreen” of casters. Just like when we apply sunscreen in the summer to protect our skin from UV rays, anti-yellowing agents can prevent casters from oxidizing reactions due to long-term exposure to UV, oxygen, or other environmental factors, thereby avoiding yellow spots or darkening of overall color.

In addition, the high-resistance caster anti-yellowing agent also has the characteristics of enhancing caster elasticity, which allows the caster to better restore its original state when under pressure and reduce the possibility of permanent deformation. In other words, it makes the casters more “elastic”, just like a spring, which can quickly rebound no matter how much external force is squeezed.

Main categories of anti-yellowing agents

Depending on the mechanism of action and chemical composition, high rebound caster anti-yellowing agents can be divided into the following categories:

Ultraviolet absorber
This type of anti-yellowing agent mainly inhibits photolysis by absorbing ultraviolet rays.The occurrence of a scientific reaction to prevent the material from yellowing. They are like “sunshades” of casters, which can block the corrosion of ultraviolet rays on the material.
Antioxidants
The role of antioxidants is to neutralize free radicals and delay the aging process of the material. This type of substance is more like the “vitamin E” of casters, which can provide additional protection to the material and extend its service life.
Light Stabilizer
Light stabilizers reduce the destruction effect of ultraviolet rays on the material by capturing light energy and converting it into heat energy. They are like the “protective covers” of casters, which can shield the influence of external light to a certain extent.
Compound anti-yellowing agent
Complex anti-yellowing agent combines the above functions, which not only has ultraviolet absorption capacity, but also has good antioxidant properties. This type of anti-yellowing agent is usually suitable for the production of casters for high-end office furniture as they provide full protection.

Type	Main Functions	Features
Ultraviolet absorber	Absorb UV rays	Specializes in UV protection
Antioxidants	Neutralize free radicals	Extend material life
Light Stabilizer	Convert light energy into thermal energy	Reduce UV damage
Compound anti-yellowing agent	Comprehensive UV absorption and antioxidant functions	Providing comprehensive protection, suitable for high-end products

It can be seen from the above classification that different types of anti-yellowing agents have their own emphasis, and enterprises can choose appropriate varieties according to actual needs. For example, for office furniture that is frequently exposed to the sun (such as conference room tables and chairs), ultraviolet absorbers should be given priority; for furniture used indoors, antioxidants or composite anti-yellowing agents can be selected.

Product Parameter Analysis of High Resilience Caster Anti-Yellowing Agent

In order to more intuitively understand the specific performance of high-resistance castor anti-yellowing agents, the following is a comparison table of key parameters for several common anti-yellowing agents. These data are derived from the test results of authoritative laboratories at home and abroad and have high credibility.

Parameter indicator	UV-531 (UV absorber)	Irganox 1076 (antioxidant)	Tinuvin 770 (light stabilizer)	Compound anti-yellowing agent A-88
Appearance	White crystalline powder	White particles	Light yellow transparent liquid	White particles
Add ratio (%)	0.3 – 0.5	0.5 – 1.0	0.5 – 1.0	1.0 – 1.5
Yellow Index Improvement Rate (%)	≥90	≥80	≥85	≥95
Heat resistance temperature (°C)	280	250	260	300
Initial Cost ($/kg)	8.0	12.0	15.0	20.0

It can be seen from the above table that although the cost of composite anti-yellowing agent is high, its comprehensive performance is also superior, especially in terms of yellowing index improvement rate and heat resistance temperature. Therefore, it is recommended to give priority to such products when budget allows.

Optimization of production process of high rebound castor anti-yellowing agent

Production process overview

The production of high rebound casters usually includes the following key steps: raw material preparation, mixing, injection molding and post-processing. The application of anti-yellowing agents runs throughout the entire process, especially during the mixing stage, special attention should be paid to the addition amount and mixing uniformity.

1. Raw material preparation

At this stage, it is first necessary to select a suitable polymer substrate, such as polyurethane (PU) or thermoplastic rubber (TPR) according to the design requirements. Then add high rebound caster anti-yellowing agent in a certain proportion. It should be noted that there may be differences in compatibility between different substrates for anti-yellowing agents, so it must be fully implemented.Verification.

2. Mixing process

Mixtures are the core link that determines the effectiveness of anti-yellowing agents. During this process, twin screw extruders or other efficient mixing equipment should be used to ensure that the anti-yellowing agent can be evenly dispersed into the substrate. At the same time, it is also important to control the mixing temperature and time. Too high temperature may lead to failure of the decomposition of the anti-yellowing agent, while too short time will affect the mixing effect.

3. Injection molding

The materials after mixing will be fed to the injection molding machine for molding. During this process, the design of the mold and the temperature setting are equally critical. For example, the surface roughness of the mold directly affects the smoothness of the casters, while the injection pressure and holding time are related to the density and strength of the product.

4. Post-processing

The next step is to polish, polish the molded casters to improve their appearance quality and feel. At the same time, the anti-yellowing performance can also be further enhanced by spraying a layer of protective film.

Practical application cases of high rebound castor anti-yellowing agent

In order to better illustrate the actual effect of high-resistance castor anti-yellowing agent, we selected two typical office furniture manufacturing cases for analysis.

Case 1: Caster project of a conference table in a certain international brand

The brand has launched a new smart conference table, requiring casters to have extremely high anti-yellowing and silent performance. To this end, they added a composite anti-yellowing agent A-88 to the caster formula and optimized the mixing and injection molding process. The final test results show that the newly developed casters have maintained a record of no obvious yellowing for more than 2 years under continuous lighting conditions, and the rolling noise is less than 30 decibels, fully meeting customer needs.

Case 2: Upgrade plan of a domestic office chair manufacturer

A well-known domestic office chair manufacturer hopes to improve product quality through technological innovation. They introduced UV-531 ultraviolet absorber and adjusted the original production process. After a series of improvements, the casters produced not only solved the problem of yellowing in the past, but also significantly improved their wear resistance and impact resistance, winning wide praise from the market.

Progress in domestic and foreign research and future prospects

In recent years, with the increase in environmental awareness and the continuous improvement of consumers’ requirements for product quality, the research and development of high-resilience castor anti-yellowing agents has also made many breakthroughs. For example, BASF, Germany has developed a new anti-yellowing agent based on nanotechnology, which has better dispersion and stability than traditional products. In China, the team of the Department of Chemical Engineering of Tsinghua University proposed a new method to synthesize anti-yellowing agents using bio-based raw materials, which not only reduces production costs but also reduces the impact on the environment.

Looking forward, with the development of artificial intelligence and big data technology, I believe that the research and application of high-resilience castor anti-yellowing agents will be more intelligent and precise.We can expect to see more innovative achievements applied to actual production and bring new changes to the office furniture industry.
