Charlotte, North Carolina - PUCA 35R, a polyurethane-modified titanate coupling agent from Polytive International, is now available in powder form for natural and synthetic rubber compounds.
When added at the mixing stage, Polytive said, PUCA 35R "quickly disperses throughout the mass to enable a coupling action between rubber polymer and carbon black and/or silica. This, the company said, helps improve physical properties, internal lubrication and flow, giving better dispersion and pigment wetting. Applications include rubber goods, shoe soles and tyres.
The Charlotte, North Carolina-based company has also introduced PUCA 30P - a newly developed PU modified titanate coupling agent additive for use in filled thermoplastic compounds, a 12 Nov statement said. (RD)
