What is hostaform material?

What is hostaform material?

Hostaform®/Celcon® acetal copolymer (POM) possesses a linear structure with a highly crystalline quality that provides a variety of characteristics: outstanding wear, long-term fatigue, toughness and creep resistance as well as excellent resistance to moisture, solvents and strong alkalis.

Is Polyoxymethylene a polymer?

POM – also known as acetal or polyacetal – is a highly crystalline, high-performance engineering polymer that displays a broad range of properties, particularly its low coefficient of friction, excellent wear resistance, high modulus and resistance to many solvents and automotive fuels.

How is Polyoxymethylene made?

How is POM made? Polyoxymethylene, like other plastics, starts with the distillation of hydrocarbon fuels into lighter groups called “fractions” some of which are combined with other catalysts to produce plastics (typically via polymerization or polycondensation).

Can POM plastic be glued?

POM is extremely solid, hard and stiff in a wide temperature range. POM has a low surface energy of ~36mN/m and therefore is typically very difficult to bond. Surface treatment will improve adhesion and bonding results significantly.

Is POM brittle?

Since POM is brittle at room temperature, linear fracture mechanic can be applied to assess fracture properties.

Is polyoxymethylene toxic?

26,27 Polyoxymethylene brackets release formaldehyde, which is toxic, allergenic, and potentially carcinogenic.

Is polyoxymethylene safe?

On the basis of the data, it is concluded that Polyoxymethylene Urea is safe for use as a cosmetic ingredient. A previous determination, however, that the concentration of free formaldehyde in cosmetic formulations should not exceed 0.2% was considered appropriate for this ingredient as well.

What is hostafarm POM made of?

HOSTAFORM® POM from Celanese is a semi-crystalline, thermoplastic polymer. HOSTAFORM® polyoxymethylene copolymer is a versatile engineering plastic with good wear resistance, hardness and rigidity.
