What is acetal plastic?

Acetal plastic, also known as polyacetal, is a thermoplastic material that belongs to the polymer family. It is characterized by excellent mechanical strength, dimensional stability and low friction. Because of these properties, acetal is used in a wide variety of applications in different industries.

Characteristics of the acetal material

Acetal is a material composed of copolymers of ethylene oxide and propylene oxide. This combination of polymers gives acetal its rigidity and mechanical strength. In addition, acetal is a thermoplastic, which means that it can be molded by injection molding processes. It is also resistant to deformation and has high chemical resistance.

Uses and applications of acetal

Acetal is used in a wide range of plastic products due to its mechanical and chemical properties. It is commonly used in the manufacture of plastic components for the automotive, electrical and electronics industries. It is also used in the manufacture of plastic products such as gears, bearings, sprockets and general engineering plastic objects.

Advantages and disadvantages of acetal plastic

Acetal has several advantages as a plastic material. Its stiffness and mechanical strength make it ideal for applications requiring high resistance. In addition, acetal is resistant to frictional wear, making it a suitable choice for parts that are in constant motion. However, acetal also has some disadvantages, such as its sensitivity to rapid thermal changes and its low UV resistance.

What is the difference between POM, Delrin and Kocetal?

POM, Delrin and Kocetal are trade names used to refer to acetal plastic. Although different names are used, these materials are very similar in terms of composition and properties. The main difference between them lies in their manufacturer or supplier.

Description of the POM

POM, or polytetrafluoroethylene, is a type of acetal characterized by its high dimensional stability and resistance to deformation. It is used in applications requiring low friction and wear resistance, such as the manufacture of bearings and gears.

Characteristics of Delrin

Delrin is another trade name for acetal plastic and shares many of the characteristics of POM. It is recognized for its rigidity, mechanical strength and chemical resistance. Delrin is used in a wide range of applications, from the manufacture of electronic components to the production of precision parts.

Kocetal properties

Kocetal is another trade name for acetal. Like POM and Delrin, Kocetal is a thermoplastic with excellent mechanical properties and resistance to deformation. It is used in applications requiring high strength and dimensional stability.

What other trade names are used to refer to these plastic materials?

POM trade names

In addition to POM, this material is also known by other trade names such as Ultraform, Hostaform and Duracon.

Other trade names of Delrin

Delrin is also known as Acetron and Celcon in the market.

Other trade names of Kocetal

Kocetal can be found under the trade names Ekonomid, Akulon and Delfor.

What are the mechanical properties of Pom and acetal?

Stiffness and mechanical strength of POM and acetal

Both POM and acetal have high stiffness and mechanical strength. These properties make them ideal for applications requiring high strength and dimensional stability. POM and acetal are widely used in the manufacture of gears, bearings and other components that need to withstand heavy mechanical loads.

Elasticity and deformation of POM and acetal

POM and acetal are materials with low elasticity and deformation. This means that they maintain their shape and resist deformation under mechanical loads. This property is especially important in applications where high dimensional accuracy is required.

Tensile strength of POM and acetal

Both POM and acetal have high tensile strength. This means that they can withstand tensile forces without breaking. This property is important in applications where tensile loads are applied, such as in the manufacture of belts and ropes.

How are acetal and POM plastic parts manufactured?

Acetal and POM injection process

The manufacture of acetal and POM parts is mainly carried out by the injection molding process. In this process, the acetal or POM material is heated until it becomes liquid and then injected into a mold. Once in the mold, the material cools and solidifies, taking the desired shape.

Molding and shaping of acetal and POM plastic parts

Acetal and POM plastic parts can come in various shapes and sizes, depending on the specific application. The mold used in the injection molding process determines the shape and size of the parts. This process allows the manufacture of parts with high dimensional accuracy and geometric complexity.

Thermal properties of acetal and POM during the manufacturing process

During the manufacturing process, acetal and POM undergo changes in their thermal properties. As the material is heated and cooled, its molecular structure changes, which affects its physical and mechanical properties. Therefore, it is important to properly control the temperature and processing time to obtain optimal results.
