Seals and gaskets in pulp equipment
What it is
Pumps, valves and connections in pulp plants use seals in PU elastomers with specific resistance to process chemicals. High-value application — seal failure can cause costly production stoppage.
The PU technology applied here is typically specific chemical-resistant pu elastomers, selected for the combination of mechanical, chemical and processing properties suitable for the application. Specific formulations vary by equipment manufacturer or final integrator, but the base system has stable characteristics documented in technical literature and segment-specific standards.
Why it matters
For the pulp and paper industry — one of Brazil's most strategic sectors, with Suzano and Klabin among global top players — seals and gaskets in pulp equipment is a decision in continuous high-pressure, high-speed operational environment. Modern paper machines operate at speeds of 1500-2000 m/min in 24/7 operation, and components must endure this regime for months between maintenance stops.
Current drivers. Brazilian pulp export drives demand for new machines and modernization of existing ones, all consuming technical components. Growth of paper packaging (replacing plastic) expands premium paper demand. Sustainability via water and energy savings in process pushes equipment redesign with more efficient components.
