Microspheres expancel to Microspheres expansion agent

Expandable microspheres to Microspheres expansion agent are white microscopic spheres (average particle size is 10~30 μm and average density is approximately 1100 kg/m3) that comprise a thermoplastic shell encapsulating a low boiling point liquid hydrocarbon. When heated to a temperature high enough to soften the shell, the increasing pressure of the hydrocarbon will cause the microsphere to expand by 40 to 100 times. The microsphere ceases to expand when its inner pressure, shell tension and external pressure reach a balance. Its density after expansion can be lower than 30 kg/m(0.03 g/cm3), making it the most lightweight application material in the world.

Application Features:

1. Good thermomechanical properties

2. Excellent elasticity: The thermoplastic shell has excellent pressure resistance, the surface can withstand a pressure of 300 kg/square centimeter, and the good resilience can withstand multiple cycles of pressure/release without breaking.

3. Excellent foaming performance: It can have 20-70 times the original independent foaming effect. After foaming, it is still a complete closed body, which has the foaming effect that traditional chemical foaming agents cannot match.

4. Environmental performance: The polymer microspheres are non-toxic and non-polluting, and can be used as an environmentally friendly foaming agent in high-end products and high value-added products.

5. Diversity to choose from: Customers can choose products with different foaming needs according to their actual needs.

6. Other applications

Applied to PVC shoes, it has the following advantages: the addition amount is small, it can make the PVC air-blown slippers ultra-light in weight and low in density, so that the product cells are fine and uniform, and the skin of the product is smooth and smooth after the product is shaped. The effect (better than other types of expansion agents), soft, high comfort, small shrinkage.


Recommended dosage:0.2-0.7% (PVC foaming leisure and sports shoes, slipper)


Package & Storage

It must be stored in a cool, dry place, and kept away from hot steam pipes and fire sources to avoid direct sunlight. This auxiliary is packed by 20kg per bag or 50kg/drum.

Product Introduction

Microspheres are a type of particle that is commonly used in a variety of industries. They are often used as an additive or filler in products, and can also be used to create microencapsulation. In recent years, microspheres have been used increasingly in the cosmetics industry due to their ability to provide a smooth and even application.

Microspheres are made from a variety of materials, including glass, plastic, and ceramic. The most common type of microsphere is made from polystyrene, which is a synthetic polymer. Microspheres can range in size from several micrometers to several millimeters.

When choosing a microsphere for your product, it is important to consider the properties of the material that you are using. For example, if you need a high degree of transparency, you will want to choose a glass or plastic microsphere. If you need good electrical insulation properties, then a ceramic microsphere would be a better choice.

There are many different ways to expand microspheres. One common method is to use an expansion agent such as nitrogen gas or carbon dioxide. This method creates uniform sized spheres that have good transparency and electrical insulation properties. Another method is to use an electrolyte solution, which creates larger sized spheres with lower transparency but higher electrical conductivity.

Product Advantage

Microspheres are a type of expandable micro bead that is used as an expansion agent in many different industries. When expanded, microspheres have a much larger diameter than their original size. This change in size allows for better control over the final product's density and other properties. Additionally, the use of microspheres can reduce voids and improve physical properties such as compressive strength.

Technical Parameters

Microspheres are small, round, uniform particles with a hollow internal structure. They are made from a variety of materials including glass, plastic, and metal. Microspheres are used in a variety of applications including cosmetics, automotive paints, and medical diagnostics.

Whenexpancel microspheres are placed in an expansion agent, they expand to many times their original size. This expansion is due to the release of gas from the microspheres' internal structure. The resulting expanded microspheres have a wide range of applications, including use as insulation in construction and packaging materials.

Product Uses

Microspheres are used as an expansion agent in a variety of industries, including construction, automotive, and aerospace. When mixed with a binder such as epoxy or polyurethane, microspheres can be used to create lightweight, strong, and heat-resistant materials. In the construction industry, microspheres are often used to create insulation panels and soundproofing materials. In the automotive industry, microspheres are used in the production of lightweight car parts and as an additive to paint and coatings to improve their durability. In the aerospace industry, microspheres are used in the production of aircraft parts and components.
