Polyoxymethylene Technology
Polyoxymethylene, also known as polytrioxane or polyformaldehyde, is by far the most important polyacetal resin. It is an engineering thermoplastic with excellent physical and processing properties. Due to its superior qualities the consumption of polyoxymethylene is fast increasing.
THE PROCESS
Starting from formaldehyde solution, the plant consists of four main units:
PROCESS HIGHLIGHTS
- The process including polymerisation is fully continuous
- The polymerisation is carried out without a solvent
- Normal commercial grade formaldehyde can be used as a raw material
- Molecular weight and polymer properties are adjustable
- Consumption figures for raw materials and energy are competitive
- Colour masterbatch production can be included
PRODUCT CHARACTERISTICS
Polyoxymethylene has excellent physical and processing properties:
- multiple impact strength
- creep resistance
- shape and dimension stability
- Selflubrication and low coefficient of static and dynamic friction
- resistance to solvents, oils, lubricants
- mechanical vibration damping capacity
