Much published literature on the way in which phase morphology and filler distribution affect blend properties is contradictory or confusing. Experiments were carried out to elucidate the relationships and to determine whether the use of compatibiliz

It is proposed that a non-polar filler can reduce interfacial energies between polar and non-polar polymers. Experiments have been carried out to test this hypothesis using carbon black as the filler in blends of natural rubber (NR) and a nitrile rub

An indirect method for determining the heat transfer coefficient of rubber to air by convection is proposed. Finite element analysis is used to simulate the cooling of a cylindrical specimen of rubber, the heat transfer coefficient being adjusted to

A method for predicting the hysteretic equilibrium temperature increase in rubber components using finite element analysis is described. It is based on two different analysis types: non-linear stress analysis and thermal analysis. An additional calcu

A test for estimating the dispersion of carbon black in rubber compounds is described. It works by examining the freshly cut surface of a specimen at low magnification in dark field illumination. Roughness of the surface related to the presence of ca

It would be advantageous to determine the causes of changes in rheological behavior of a compound during mixing, so that mixing times and conditions could be optimized to give the desired processing behavior and properties of the final product. The c

The distributive mixing characteristics of three internal mixers are examined: a Parrel BR Banbury (1.6 L), a Farrel F40 Banbury (40 L), and a Francis Shaw K1 Intermix (5.5 L). The former two machines have two-wing tangential rotors while the latter

Certain accelerators are susceptible to chemical attack by water. Consequently, the cure behavior of compounds containing these accelerators is likely to be affected by the water content of the compound and the humidity conditions of processing and s

The interfacial effects of a multifunctional additive (MFA), the n-tallow-propane-1,3-diamine salt of carboxylic acid, on carbon black filled rubber have been studied. The surfaces of three normal-cure-rate carbon blacks, of differing nitrogen BET su
