All POM manufacturers modify their resins and provide basic resins to independent blenders. Modified POM accounts for about a quarter of total resin sales, mainly for filling and strengthening, and a small amount for high lubrication, toughening, anti-static, electroplating and other grades. The final use of polyformaldehyde varies according to the industrial structure of different regions. Japan consumes the highest proportion of polyformaldehyde in electronics and electricity, and Western Europe consumes the largest amount of polyformaldehyde in the automotive industry. Sprinkler irrigation of industrial instruments and pipe fittings in the United States is an important market for polyformaldehyde.
