In polymer chemistry, there are lots of kinds of commercial plastic products are produced. The biggest market inside this polymer chemistry and industry is thermoplastics. Acetal is a very important thermoplastic material that has various kinds of applications in engineering and daily use. These application areas of acetals are because of its specific properties. In here, we give summary informations about acetals.
What Are The Properties Of Acetal?
Acetal has an another name that is ‘polyoxymethylene’. The source thermoplastics material that acetal is produced from is ‘formaldehyde(CH2O)’. Acetal has very important mechanical characteristics and properties around other thermpolastic materials; High stiffness, toughness, strength and wear resistance properties of acetal make this material very important for such applications. Acetals has high melting temperature compared with other thermoplastics. And it is insoluble at open air with solvents.
Becuase of these competitive properties, acetal is used in such applications instead of metals such as automotive parts, door handles etc. Because of its wear and corrosion resistance, acetal materials can be used in pump housings.
Material Specifications Of Acetal
- Modulus Of Elasticity Of Acetal: 3500MPa(507,630 lb/in2)
- Tensile Strength Of Acetal: 70 MPa(10,150 lb/in2)
- Symbol Of Acetal: POM
