Effect of Thiophene-Plasma Coating of Silica on the Reinforcing Performance in EPDM, SBR and NBR

The filler surface chemistry is a crucial factor for the level of dispersion and filler-polymer interaction in rubber. Plasma-polymerization allows tailoring the surface chemistry without influence on the bulk properties. Thiophene was used as monomer in this study due to its sulfur moiety, and the plasmathiophene (PTh) coated silica was blended with EPDM, SBR and […] mehr...

Dynamic – Mechanical Properties of Solution Styrene Butadiene Rubber Loaded with Silica

The effect of silica and its surface chemical modification by silane (Si69) on the dynamic-mechanical properties of solution styrene-butadiene rubber (S-SBR) was investigated. Dynamicmechanical measurements were done to evaluate both the real and imaginary parts of the shear compliance over a wide range of frequency and temperature, 10-4 to 100 Hz and -50 to 120 […] mehr...

Compatibilization of Elastomer-Filler Combinations by Plasma Polymerization

A good distribution of fillers and elastomers in a compound is a challenging task, as these components greatly differ in polarity. One possibility to overcome the polarity differences between fillers and polymers is to adjust the surface properties of the filler by plasma polymerization: A proper choice of the monomer and the process parameters allows […] mehr...

The Physics of Confined Polymers in Filled Rubbers

Why Silica Technology Needs S-SBR in High Performance Tires?

The advantage of silica in combination with S-SBR in modern PC tire tread rubber compounds is explained by considering effects of polymer confinement. Silica is a structure having pores in the nanometer regime, i.e. with pore sizes in the order of the primary polymers prior crosslinking. In this case confinement effects of polymers come into […] mehr...

Filler Impact on Rubber Blend Miscibility

Applying calculated Hildebrand solubility parameters based on Hoy molar attraction constants is most often a sufficient tool to predict the polymer blend miscibility behaviour of the unfilled state correctly. Miscibility is experimentally determined via atomic force microscopy and via glass transition criteria applying either thermal or viscoelastic response methods. The impact of silica and carbon […] mehr...
