Polyacetal is a thermoplastic used in engineering plastics. Other names for Polyacetal include Delrine, Hostaform, Draken, Silken, and Ultraform. Polyacetal resins, also called polyoxymethylene resins, are widely used in various industries such as agriculture, transportation, construction, etc. The electrical and electronics industries are the largest consumer markets for this material; Polyacetals are used to make electrical and electronic components such as switches, telephones, office machines, computer keyboard buttons, and printers. In the continuation of this PETROPROVIDERS article, join us to show you Polyacetal applications.

What are the interesting features of Polyacetal?

Polyacetal applications are very widespread in global industries; This is because of their interesting and special features. Polyacetal density is between 1.41 to 1.43 g / cm and its melting point is 165 to 175 ° C. If polyacetal is exposed to temperatures above its melting point, the polymer will decompose and release toxic gases. Solvents are Polyacetal DMF (dimethylformamide), dichlorobenzene and dimethylbenzene. It is interesting to know that the transfer temperature of polystyrene glass is minus 75 degrees Celsius.

Polyacetal is almost fire-resistant, burns in the flame, and continues to burn, its flame is blue and invisible. Polyacetal also burns without smoke, dripping on the flame and releasing a toxic odor (formaldehyde odor).

Types of polyoxymethylene and polyacetal applications

  1. Antistatic polyacetal
  2. Polyacetal detectable by metal detector
  3. Conductor polyacetal

How is polyacetal produced?

POM production

POM production

Ordinary polyacetals are made from formaldehyde, also called polyoxymethylene. The formaldehyde polymerization process is performed by anionic initiators such as triphenylphosphine.

Polyacetal was first produced by DuPont in 1956 and marketed under the brand name Delrin. The percentage of crystallinity in Polyacetal is high and due to its properties, it can be used as a substitute for non-ferrous metals. By adding glass fibers to polyacetals, its stiffness and creep resistance can be improved.

Will the construction of Polyacetal production units be profitable?

Those interested in the petrochemical industry can build Polyacetal production units; Because the product has a significant profit, this design will have many benefits for manufacturers.

The raw materials needed to produce this material can be obtained from active petrochemical companies in countries around the world. It should be noted that in the Middle East, there is no Polyacetal production unit and all the needs of Asian countries are met through imports from European countries and China.

Therefore, due to the unrivaled nature of this product, a monopoly market can be created. In addition, Polyacetal applications are very diverse in different industries; As a result, the demand for this material is high.

Types of Polyacetal and their applications in the world:

Today, different types of plastics are used in different industries according to their specific characteristics and properties.

This polymer is available in 5 models: homopolymer, copolymer, alloy, reinforced, and improved wood, which is marketed with some additives.

Homopolymers and copolymers are usually similar in general characteristics, but the difference between the two groups is in their thermal-mechanical properties and hydrolysis.

A note about Polyacetal applications:

Another thing that can be said about this plastic is that the higher temperature than the temperature of this plastic, causes the final product to discolor. Excellent electrical and mechanical properties Polyacetal does not shrink under ambient humidity and does not shrink due to long-term operation.

As a result, Polyacetal has high dimensional and dielectric stability, and as a result, POM is in many cases a better choice for metal replacement than polyamide.

The performance of sliding parts, underwater parts, and precision parts with Polyacetal will be excellent. In addition, its non-toxicity has made Polyacetal one of the best options for food-related components.

A summary of the review of Polyacetal applications in the world

In this article, we looked at and reviewed Polyacetal applications. This polymer is used to produce various parts and is used in various industries.

Today, more than 70% of global POM production capacity is located in Asia. The production market of this product has been growing by approximately 4.5% annually and in total about 1350 kg in 2018.

The main buyers are the automotive and electronics industries. Polyoxymethylene was discovered by the German chemist Hermann Stoddinger in 1920, but due to stability and thermal problems, the polymer was not commercialized at the time.

This polymer was first marketed in 1956 by the American company DuPont as a homopolymer under the brand name Delrin. Polyacetal is an engineering polymer with a wide range of applications that has properties similar to metals. Polyacetal polymer material, due to its special abrasive properties, as an industrial polymer has been able to replace some metals in various industries in special cases, especially in the automotive industry.

This polymer has excellent properties that fill the gap between ordinary polymers and metals. Since the entry of this polymer into the industry, we have witnessed its wide applications in various industries such as automotive, electrical equipment, construction, electronics, and many other industries.
