Reduce Friction, Improve Slip
Slip additives reduce friction in plastic moving parts and solve performance
drawbacks of external lubricants such as waxes, greases and silicone oils,
which can migrate under stress. However, many slip additives require high
loadings, adversely affecting the mechanical properties of finished plastic
parts, particularly tensile modulus and impact resistance.
Dow Corning’s advanced silicone additive technology overcomes this
issue by delivering high slip performance at dosage levels as low as 2% to 3%,
compared to the 15% loading typical of PTFE. Our silicone-based additives lower
the coefficient of friction (COF) of your plastic resin or compound more
effectively than PTFE to reduce heat, noise, wear and abrasion in finished
parts – with minimal compromise to mechanical performance.
These anti-friction additives also help you control costs through lower
loadings. By contributing virtually no VOCs, they address the requirements of
VDA 278 (10/2011).
Solving Your Application
Dow Corning COF reducing technologies are particularly valuable in
applications such as bearings, gears and conveyor belts; window lifting
systems; steering column sensors; roller shutter systems; appliances; sports
equipment; and various other applications requiring slip.
