Is the MTK MARINE steel and aramid braided thermoplastic hose suitable for use with isocyanates and polyols in high-humidity or saline environments?

Yes. The MTK MARINE steel and aramid braided thermoplastic hose is specified for solvents, paints, isocyanates, polyols and water-based fluids and is therefore suitable for use with isocyanates and polyols. Its construction . polyamide inner layer, aramid + steel braided reinforcement and polyurethane outer layer . provides chemical compatibility for those materials while delivering high mechanical strength (working pressures from 200 to 500 bar depending on diameter). It is also rated for operation in high-humidity and saline air environments, so it can be used in such conditions. Operating temperature range is -40Â°C to +100Â°C (for water and air up to +70Â°C). Note: confirm compatibility with specific isocyanate/polyol formulations and required service conditions (pressure, temperature, abrasion, and any cleansing/solvent exposure) before final selection; micro-perforated option is available on request for gas/air applications.

Can MTK MARINE steel and aramid braided thermoplastic hose be supplied in micro-perforated form for gas or air applications?

Yes. MTK MARINE steel and aramid braided thermoplastic hose Format can be supplied in microâperforated form for gas or air applications on request. The hose is lightweight and flexible, with a polyamide inner layer, aramid + steel braid reinforcement and a polyurethane outer layer. It is suitable for solvents, paints, isocyanates, polyols and waterâbased fluids, and for operation in high humidity and saline air. Working pressure ranges from 200 to 500 bar depending on diameter; operating temperature is â40Â°C to +100Â°C (for water and air up to +70Â°C).

Can MTK MARINE steel and aramid braided thermoplastic hose handle working pressures up to 500 bar across all diameters?

No. MTK MARINE steel and aramid braided thermoplastic hose cannot handle 500 bar across all diameters. The product specification states a working pressure range from 200 bar to 500 bar depending on hose diameter, so maximum 500 bar applies only to certain (typically smaller) diameters while larger diameters will have lower rated working pressures. Always confirm the specific working pressure rating for the exact diameter you intend to use.
