POM-H

Commonly said homopolyformaldehyde refers to DuPont‘s Delrin®. Because of the high crystallinity of homopolymer molecular structure, its strength characteristics, elasticity, impact strength and melting point are better than those of co-formaldehyde. General polyformaldehyde refers to the copolymer of polyformaldehyde. Because of the carbon - carbon combination in the molecular structure of coformaldehyde, it has high stability. Because of its high stability, compared with homopolyformaldehyde, it is difficult to degrade and deteriorate the material. Therefore, from the use of time, the decline of the physical properties of co-formaldehyde than homopolymer to be small.
