Ingredients, special compounding resins

The compounding ingredients for preparation of adhesion test specimens, magnesia (MgO), zinc oxide, Zalba Special (hindered phenol antioxidant from E. I. duPont de Nemours and Co.), and Bakelite-brand t-butylphenolic resin CK-1634 (Union Carbide Corp.) were used as... 

The specific ingredients are resin, reinforcement, pigments or dyes, lubricants, and solvents. Each of these ingredients has specific characteristics that are measurable and controllable and the compound producer can, and often will, supply the molder with test data on each production blend the customer has received. The special characteristics of each of these ingredients are as follows ... 

Addition of a small amount of PA improves processability of the specialty resin and is beneficial to performance of the GE-reinforced systems. Addition of specialty resin to PA enhances the thermal behavior and rigidity of the latter resin. For higher concentration of these ingredients, compatibilization and impact modification are required. Since PA is sensitive to heat, oxygen, and moisture, the compounding requires a special care. Examples are listed in Table 1.60.
