Product Description

Product Description

      Polyformaldehyde is a thermoplastic crystalline polymer. Known as "super steel" or "game steel", also known as polyoxymethylene. The English abbreviation is POM. Generally, the polymer obtained from formaldehyde polymerization has low polymerization degree and is susceptible to pyrolytic polymerization. It can be used as raw material of organic chemical industry, synthetic resin, and also used as drug fumigant.

Advantage

1.With high mechanical strength and rigidity;

2.The highest fatigue strength;

3.Environmental resistance, good resistance to organic solvents;

4.Strong resistance to repeated impact;

5.A wide range of temperature (-40ºC~120ºC);

6.Good electrical properties;

7.Good resilience;

8.With its own lubricity, good wear resistance;

9.Excellent dimensional stability.

Folding typical application range

      POM has a very low coefficient of friction and good geometric stability, especially suitable for the production of gears and bearings. Because it also has high temperature resistance, it is also used in pipeline devices (pipeline valves, pump housings), lawn equipment, etc.

Packaging & Shipping

   

Everyone knows the devil is in the details. As for packaging, we prefer durable bags that can fully withstand shock, vibration and pressure changes during transportation. We will choose the corresponding packaging type according to the material,weight, size, shape and volume of the goods. Pay special attention to the packaging should be clean and dry without odor and oil, and there should be no prominent nails, hooks, thorns, etc.

We will choose packing materials such as wooden boxes, pallets, wooden frames, aviation cases, etc. At the same time, foam bubble film stretching film is used to fill or protect the inside and outside of the goods to prevent unnecessary losses caused by movement of the goods or collision with each other.

At the same time, it is necessary to ensure the waterproof and moisture-proof ability of the packaging, and consider the multi-directional customers to let customers buy peace of mind.

Factory delivery strength, arrange special personnel responsible for packaging and shipping, large annual output, loading equipment and transportation advanced convenient, high efficiency.
Sea, land and air transport modes to meet the ultimate needs of customers, is bound to bring superior purchasing experience for customers.
At the same time we constantly improve the quality of packaging, improve packaging methods, reasonable choice of means of transport and transport routes, the development of social transport system.
