Who knows what the downstream products of polyoxymethylene are, and what are the product upgrades for polyoxymethylene?

Are the downstream products injection-molded products? The original poster can check Boli’s website; there, market information is available

Right, cars, home appliances, and so on

http://www.polyplastics.com/ch/product/appli/index.vm It’s Polyplastics’ website in Japan; you need to register and log in to access it. I have a brief overview of the properties of POM as well as market information related to Korean projects; please send me your email address if you need it

This post was last edited by pecker on 2009-6-19 06:37. Are you asking about the downstream products of formaldehyde or those of polyformaldehyde? For polyoxymethylene, its structural formula is:; its properties are quite stable, unless the hydrogen atoms attached to the carbon atoms in the straight chain are replaced by a few substituents with active properties – these would fall under the category of downstream products you mentioned. As for the substituents, they can be halogen substituents such as chloro and bromo groups, as well as others. Downstream products of formaldehyde that are of interest to the industry include polyformaldehyde and polymeric formaldehyde, among others. It should also be noted that your statement about a \"product upgrade for polyoxymethylene\" is quite unusual; such phrasing does not meet the requirements of professional terminology used in fields related to chemistry, such as chemistry and chemical engineering. BTW: I have a suggestion for the original poster – your way of phrasing your questions shows that you know very little about chemistry, and the terminology you use is unsophisticated, which makes it difficult to understand your questions. If you are currently in a position related to the field of chemistry, it is recommended that you study the organic chemistry section of high school chemistry textbooks as well as university-level courses in organic chemistry.

POM is used the most in the automotive industry; it is also applied in electronics and electrical equipment as well as packaging machinery. In the automotive industry, it is mainly used to replace metal components, such as the main structural parts in gasoline pumps and pump bracket assemblies (such as flanges, filters, level sensors, etc.), radiator valves, radiator caps, fans, and so on. Furthermore, thanks to POM’s wear and fatigue resistance, it is also commonly used in machinery for manufacturing components such as gears, bearings, and pulley pipe fittings. We use products from Polyplastics and BASF the most.

7# leonqin: It seems that the performance of BasF’s polyoxymethylene products is not better than those made in China. What brand do you use?

H2320/S2320/N2200 G43, etc

9# leonqin, you work in the automotive parts industry, right? Most of BASF’s products are used in fuel tanks

Well, it is mainly used in automotive fuel systems.
