Definitions

  • lignins There are substantial markets available to lignins if they can achieve the same melt and flow characteristics as a phenolic resin. There are at least two major factors of this present invention which allow these new modified lignins to be able to totally replace phenolic resins.
  • the first factor that has been that a lignin which does not have any distinct melt point or flow characteristics can be modified with a certain amount of polyether glycol to achieve a certain desired melt point. So, what occurs is a certain ratio of lignin to a polyether compound (such as polyether glycol) produces a product which has a distinct melt point and melt viscosity. This effect can be thought of as a type of plasticizing effect wherein the lignin can be thought of as the hard resin.
  • lignin is derived from wood, which is a natural product. As in all natural products there will exist a certain amount of variation depending on the exact type of wood, age and other conditions. These variations are another major reason why lignins have not been extensively utilized as replacements for phenolic resins, whereas a synthetic phenolic resin can be made to exact and reproducible specifications, and the lignin molecule may have wide variations. Therefore, if there is a variation in the lignin this can be adjusted by changing the ratio of lignin to a polyether compound (such as polyether glycol) in order to achieve the desired melt and flow characteristics.
  • a polyether compound such as polyether glycol
  • lignins are a natural product and as such there may be natural chemical variations in the lignin molecule. These variations may include different functional groups or different concentrations of these functional groups. These variations become rather significant when you are trying to formulate a product that must have, in addition to certain physical properties such as melt and flow, certain curing characteristics in order to produce a consistent product day in and day out.
  • lignins can be used as either partial or total replacement of phenolic resins in phenolic production.
  • One major advantage is that lignins can offer significant economic advantages. Since most phenolic resins are made from phenol and phenol is a petrochemical product, cost of phenol is very dependent on the cost of oil. So, as the cost of oil increases, the cost of phenol and phenolic resins will also increase. These price increases could make phenolic resins less competitive and thereby make it possible for these phenolic products to be replaced by other products.
