POM塑料颗粒可以提供多种颜色

POM塑料颗粒可以提供多种颜色，POM的全称是聚甲醛树脂，英文名是聚甲醛（简称POM）。它是一种热塑性结晶聚合物，分子式如下：

聚甲醛（POM）的主链由-C-O-组成，应具有“柔性”。链段的内部旋转应该很容易，但由于规则对称的化学结构，分子间作用力大，容易结晶，这使得分子运动和链的内部旋转变得困难，因此它是一种无侧链、紧密堆积、高密度和高结晶度的线性聚合物

均聚甲醛具有高密度、结晶度和熔点，但热稳定性差，加工温度范围窄（约10°C），酸碱稳定性稍低

在均聚甲醛工艺中，聚合单体甲醛具有化学活性，不利于聚合和最终产品。目前，只有杜邦和朝日生产高聚甲醛，约占市场的20%。其余的制造商都生产共聚甲醛

Product Details

POM plastic particles can provide a variety of colors

The full name of POM is polyformaldehyde resin, and the English name is polyformaldehyde (POM for short). It is a thermoplastic crystalline polymer with the following molecular formula:

The main chain of polyoxymethylene (POM) is composed of -C-O-, which should be “flexible”. The internal rotation of the chain segment should be easy, but due to the regular and symmetrical chemical structure, the intermolecular force is large and it is easy to crystallize. , Which makes it difficult for molecular movement and internal rotation of the chain, so it is a linear polymer with no side chains, compact packing, high density and high crystallinity.

Polyoxymethylene (POM) is another engineering plastic with excellent comprehensive properties after polyamide (PA). It has high mechanical properties, such as strength, modulus, wear resistance, toughness, fatigue resistance and creep resistance. It also has excellent electrical insulation, solvent resistance and processability, and is one of the general engineering plastics.

Polyoxymethylene (POM) is known as “Saigang”, “Duogang” and “Super Steel” abroad. At a lower cost than many other engineering plastics, it is replacing some markets traditionally used by metals, such as replacing zinc and brass. , Aluminum and steel make many parts. Since its inception, polyoxymethylene (POM) has been widely used in electronic and electrical, machinery, instrumentation, daily light industry, automobiles, building materials, agriculture and other fields. In many new areas of applications, such as medical technology, sports equipment, etc., polyoxymethylene (POM) has also shown a good growth trend.

(2) Classification and performance comparison

Polyoxymethylene can be divided into homopolyoxymethylene (trioxymethylene or a homopolymer of formaldehyde) and copolyoxymethylene (copolymerization of trioxymethylene and a small amount of dioxane) according to the different chemical structure in its molecular chain. The main difference between the two is:

Homo-formaldehyde has high density, crystallinity, and melting point, but poor thermal stability, narrow processing temperature range (about 10°C), and slightly low acid-base stability;

Copolyformaldehyde has low density, crystallinity, melting point and strength, but it has good thermal stability and is not easy to process. It has a wide processing temperature range (about 50°C) and has good acid-base stability.

In the homopolyoxymethylene process, the polymerized monomer formaldehyde is chemically active, which is not conducive to polymerization and the final product. Currently, only DuPont and Asahi produce homopolyoxymethylene, which accounts for about 20% of the market. The remaining manufacturers all produce copolyoxymethylene.
