Application of Polyurethane on Stress Balls

The Basic Introduction to Polyurethane

Polyurethane (PU) is a polymer material usually made by reacting an isocyanate (or polyisocyanate) with a polyol. Its chemical composition consists of two main parts: an NCO group based on isocyanate and an OH group based on polyol. These two groups intermingle in the reaction to produce polyurethane chains.
Polyurethanes have diverse structures and can be classified into linear polyurethanes, cross-linked polyurethanes, and polymeric microcapsules. Linear polyurethanes are mainly used in the manufacture of elastomers, sealing materials, adhesives, and so on.; cross-linked polyurethanes are used in the manufacture of foams, coatings, and shoe soles.; polymeric microcapsules are used in the manufacture of retardants, and so on.
Polyurethane has many special properties, such as high strength, elasticity, weather resistance, abrasion resistance, chemical resistance, fatigue resistance, and so on. Also, polyurethane has different characteristics such as hardness, color, and transparency., which can be adjusted according to different applications. Therefore, polyurethane has a wide range of applications, such as manufacturing automobile parts, aviation parts, artificial leather, foam materials, shoe sole materials, coatings, sealing materials, rubber replacement materials, and so on.

Definition and Function of Stress Balls

A stress ball is a small ball used to relieve stress, usually made of elastic, soft material, such as polyurethane material. Its size can be freely adjusted according to the needs of the general can be held in the hands, by squeezing, kneading, and other actions to relieve physical stress and anxiety.

Stress relief balls can effectively relieve stress and anxiety and help relax the body and mind. For those who suffer from anxiety and tension due to stressful work, study, or life, using a stress relief ball can help relieve feelings of fatigue and tension and improve work and study efficiency. In addition, the stress relief ball also helps to enhance hand muscle strength, promote body circulation, and other effects. Long-term use of stress relief balls can also exercise hand muscles, improve hand flexibility and prevent diseases such as stiff fingers.

In short, the role of the stress relief ball is not limited to relieving stress and anxiety, but also to promoting physical health, improving the quality of life, and other multiple effects. It has become an essential gadget in the life and work of many people.

Material Selection and Development History of Stress Balls

Stress relief balls are a very popular stress relief tool that can be used to relieve stress, and reduce anxiety and pressure while enhancing finger sensitivity and muscle strength. The selection of materials and the history of the development of stress balls are as follows:

Initial material selection

The original stress ball material was made of elastic materials such as rubber and silicone. The elasticity of these materials can provide a sufficient bounce and squeeze effect. However, these materials sometimes produce odor and are not suitable for people with sensitive skin.

Popular material choices nowadays

Nowadays, common stress ball materials include polyurethane, silicone, and rabbit hair application with active plant extracts, among which polyurethane and silicone materials are widely used. Polyurethane materials have better durability and compression resistance, while silicone materials are softer, more vertical, and better suited for tumbling. In addition, for people with sensitive skin, some brands now use materials such as pure natural plant materials and rabbit hair applications with active plant extracts to ensure quality and safety.

Development History

Stress relief balls first originated in the 1970s when the balls were made of rubber material and the shape and size of the balls were larger than today’s balls. Later, as people realized the importance of mental health, stress relief balls began to become more popular, and the material and shape of the balls were improved.

In short, the selection and use of stress ball materials have progressed and developed greatly, and now the materials used are of better quality, safer, and more fashionable.

Analysis of Different Material Stress Balls

Mainly divided into three aspects of physical properties, chemical properties, and production costs of the comparison.

Physical Properties

Polyurethane stress balls: have good elasticity and durability, can be reused, and can withstand a certain amount of pressure and stretching.
Foam ball: foam ball is often used, but not durable enough, easy to break or deform.
Rubber ball: rubber ball has a long service life, but is not as elastic as polyurethane material, and easy to age and harden.
PVC ball: PVC ball is lightweight, but it is easy to break and has poor durability.

Chemical Properties

Polyurethane stress ball: non-toxic, odorless, will not cause pollution to the environment, but vulnerable to damage by sunlight and oxidizing agents.
Foam balls: Foam balls may contain chemicals such as styrene and polyurethane, which can be polluting to the environment.
Rubber balls: They contain rubber and vulcanizing agents, which may have an impact on the environment.
PVC ball: Contains chlorine, which is not good for the environment and may release toxic substances.

Production Costs

Polyurethane stress ball: relatively high production cost.
Foam balls: low production cost and easy to produce in large quantities.
Rubber ball: higher production cost, but due to its long service life, it does not need frequent replacement, which can reduce maintenance cost.
PVC ball: lower production cost.

On balance, polyurethane stress balls have better physical and chemical properties but are relatively expensive to produce. While other materials of stress balls are cheaper, their durability is poor and there is a problem of environmental impact, so the choice of stress balls needs to be weighed on a case-by-case basis.

Process Flow of PU Preparation Stress Ball

Raw material selection

The raw materials for the preparation of polyurethane stress balls include polyether polyol, diisocyanate, catalyst, additives, and so on. In the selection of raw materials, factors such as molecular weight, water content, and hydroxide index of polyether polyol, and parameters such as isocyanic content and molecular weight of diisocyanate should be considered.

Preparation Process

Raw material pretreatment: Pre-treat the polyether polyol with quality inspection and drying, and weigh the diisocyanate precisely.
Mixing: Polyether polyol, diisocyanate, catalyst, additives, and other raw materials are mixed in a certain ratio to make them evenly dispersed.
Reaction: The mixed raw materials are injected into the mold and reacted for a certain period of time to form the polyurethane material.
Forming: The polyurethane material is taken out of the mold for cutting, polishing, and other forming processes.

Quality Control

In the process of preparing stress balls, quality control is required to ensure product quality. The main control content includes mixing ratio, reaction time, molding temperature, and other aspects, while the finished products are tested for resistance to compression, abrasion, and high temperature to ensure that they meet customer requirements.

Physical and Chemical Property Analysis

The physical and chemical properties of polyurethane stress balls are analyzed as follows:

Elasticity: With excellent elasticity, it can withstand large deformation without breaking within a certain degree.
Hardness: According to different needs and application scenarios, the hardness can be adjusted according to customer requirements.
Wear resistance: With excellent wear resistance, it can be used for a long time under heavy-duty working conditions without wear and tear.
Chemical resistance: It has strong chemical resistance and can resist most chemical substances.

The performance test of polyurethane stress balls mainly includes the following aspects:

Compression strength: The compression strength of polyurethane stress balls is evaluated by a compression test.
Air aging: The samples are exposed to high temperatures and high humidity for a certain period of time to assess their aging resistance.
Abrasion resistance: The abrasion resistance of polyurethane stress balls is tested by the rotating friction test and sliding friction test.
Chemical corrosion: The chemical corrosion of polyurethane stress balls is tested using acid and alkali immersion tests, solvent immersion tests, and so on.

In general, polyurethane stress balls have excellent physical and chemical properties, showing outstanding performance in compression strength, wear resistance, chemical resistance, and so on.
