Is the VE7 double braided polyester thermoplastic hose compatible with solvents, paints, isocyanates, polyols, gases, air, and water-based fluids across its temperature range (-40Â°C to +100Â°C)?

Yes.with qualifications. The VE7 double braided polyester thermoplastic hose is specifically designed for use with solvents, paints, isocyanates, polyols, gases, air, and water-based fluids, and its construction (polyamide inner layer, double polyester braid reinforcement, microâperforated polyurethane outer layer) and compliance with SAE 100R7 / ISO 3949âR7 indicate general compatibility across its rated temperature range of â40Â°C to +100Â°C. However note the stated exception: for water and air the maximum recommended temperature is +70Â°C, not +100Â°C. For aggressive solvents, high concentrations, specific isocyanates/polyols or certain gases, and for any application near the upper or lower temperature limits, verify chemical compatibility and pressure/temperature ratings with the hose manufacturer or chemical supplier before use.

Can the VE7 double braided polyester thermoplastic hose withstand continuous use at +100Â°C when transporting solvents and isocyanates?

VE7 double braided polyester thermoplastic hose is rated for operating temperatures up to +100Â°C, but the specification adds a limitation: for water and air the max is +70Â°C. For solvents and isocyanates the general +100Â°C rating applies, provided chemical compatibility with the hose materials (polyamide inner layer and microâperforated polyurethane outer layer) is confirmed. Continuous use at +100Â°C with aggressive solvents or isocyanates can accelerate material degradation-verify compatibility data from the manufacturer and perform application-specific testing (pressure, exposure time, concentration). Without explicit manufacturer confirmation for continuous highâtemperature exposure to those specific chemicals, continuous operation at +100Â°C is not recommended.

Does the VE7 double braided polyester thermoplastic hose resist micro-perforation damage from abrasive solvents and polyols?

YesâVE7 double braided polyester thermoplastic hose offers good resistance to micro-perforation from abrasive solvents and polyols, but with some limits. Why: the hose construction is specifically designed for solvents, paints, isocyanates, polyols and similar fluids. Key protective features are: - Inner layer of polyamide (good chemical and abrasion resistance compared with many elastomers). - Reinforcement: double polyester braid (provides mechanical strength and abrasion resistance under pressure and flexing). - Outer layer: micro-perforated polyurethane (polyurethane provides excellent abrasion resistance and mechanical protection; âmicro-perforatedâ indicates breathability/drainage while retaining surface durability). Practical limits: while the materials and construction reduce the risk of micro-perforation from abrasive solvents and polyols during normal use, resistance depends on service conditionsâpressure, flow velocity, particulate content, chemical aggressiveness, temperature, flexing cycles and installation abrasion. Operating temperature range is â40Â°C to +100Â°C (note: for water and air up to +70Â°C), so prolonged exposure near the upper limit or to aggressive solvent mixtures at high temperature can accelerate wear. Polyurethane outer layers can be worn by sharp particulates or continuous scraping; micro-perforation implies small engineered pores which may increase susceptibility if exposed to highly abrasive solids. Recommendation: VE7 is appropriate for applications involving solvents and polyols where mechanical protection and chemical compatibility are required, but for heavy particulate abrasion, extremely aggressive chemistries or continuous high-temperature service consider additional protection (armoring, abrasion sleeves) or a hose specified for slurry/abrasive duty.
