Synthetic Resin TC is a ketone-aldehyde condensation resin
that serves as a carrier resin for pigment concentrates with universal solubility.
Low weight bark based panels glued with a condensation resin
(8 to 12 % UF based on the oven-dried weight of particles) were found to show sufficient mechanical strength (MOR, IB, CR (compressive resistance), T (tensile strength), TS) for insulation purposes (Kain et al.
A similar fate, for controversial pollution and health reasons, could be in store for bisphenol A, one of the most useful raw materials in the production of phenolic/epoxy condensation resins. The chemical structures of these derivatives are shown in illustration 1.
They are, in essence, alkylated (t-butyl) phenol-formaldehyde condensation resins referred to broadly as novolacs.
This epoxy-functional styrene/acrylic oligomer, provided as a masterbatch in a variety of carrier resins, can be added to degraded condensation resins to re-link broken polymer chains in an extruder.
Test data measured the value added to reclaimed condensation resins as indicated by four key characteristics: melt strength and processability, mechanical properties (Izod impact and tensile strength), hydrolytic stability, and clarity (light transmission).
Decorative laminated plastic sheets which consist of papers, fabrics or other core materials that have been laminated at pressures normally between 1,000 and 1,400 psi, using thermosetting condensation resins
Owing to increasingly rigid formaldehyde restriction guidelines, a new generation of low-emission formaldehyde-based condensation resins
