          一、Product Presentation
          Solid phenolic resin is yellow, transparent and amorphous block material, which is slightly red because it contains free phenol. The average proportion of the entity is about 1.7, which is easily soluble in alcohol, insoluble in water, and stable to water, weak acid and weak alkali solutions.Resins made of phenol and formaldehyde by condensation, neutralization, and water washing under catalyst conditions.Due to the different selection of catalysts, it can be divided into two categories: thermoconsolidation and thermoplasticity.Phenolic resin has good acid resistance energy, mechanical properties, heat resistance energy, widely used in corrosion prevention engineering, adhesive, flame retardant materials, sandwheel sheet manufacturing and other industries.
          二、Product Features
          ² The solid phenolic resin is a yellow, transparent and amorphous block substance, slightly red for containing free phenol.
          ² High temperature resistance, can maintain its structure integrity and size stability under high temperature.
          ² Weak acid and weak alkali resistance, decomposition in strong acid and corrosion in strong alkali.
          ² It is a versatile substance compatible with a wide variety of organic and inorganic fillers.
          三、Product Purpose
          Phenolic resin is mainly used to manufacture various plastics, coatings, rubber products, adhesives and synthetic fibers.
