Description

Sinopec Ester-based Fire-resistant Hydraulic Fluid 4632 is a range of polyol ester type hydraulic fluids formulated with selected additives, available in four ISO viscosity grades: 32, 46, 68 and 100. This biodegradable and environmentally responsible fluid, which does not contain water, mineral oil or phosphate esters, can be used in place of a conventional antiwear hydraulic fluid in applications where there is a risk of fire or accidental environmental contamination, where it achieves excellent hydraulic fluid performance

Applications

Sinopec Ester-based Fire-resistant Hydraulic Fluid 4632 is suitable for use in:

  • Hydraulic applications where there is a risk of fire or of accidental environmental contamination, where a conventional mineral-oil based antiwear hydraulic fluid would present a fire hazard or pollution hazard.

  • Hydraulic applications where a fire-resistant antiwear hydraulic fluid of type ISO 6743/4 HFDU or ISO/FDIS 12922 is required.

Features & Benefits

  • High flash point (270°C) and fire point (330°C) make the fluid resistant to fire, offering a safer working environment and greater equipment protection.

  • Excellent antiwear performance in hydraulic pumps and valves when used in accordance with the equipment manufacturers’ recommendations.

  • Excellent thermal and oxidation stability reduce the formation of deposits and sludge and prevent valve sticking, ensuring longer system life and extended drain intervals.

  • High shear stability means the fluid stays in grade and is not broken down in service.

  • Very high viscosity index (VI > 180) provides outstanding viscosity–temperature performance compared to conventional mineral oil (VI ~ 100) and phosphate ester (VI < 0) hydraulic fluids.

  • Good lubricity properties, provided by the polyol ester fluid, protect hydraulic components from wear.

  • Compatible with iron, steel, and most non-ferrous metals and their alloys.

  • Wide operating temperatures range – from –20°C to 90°C.

  • Suitable for use in hydraulic systems operating at a constant pressure of >40 MPa.

  • Non-toxic, non-irritating and contains no hazardous ingredients, so safe to use and handle.

  • Readily biodegradable and non-toxic to aquatic life, so suitable in applications where accidental spillage or leakage of fluid is possible.

  • Excellent storage stability and long product life – comparable to conventional mineral oil fluids or polyglycols.

    Comfortable and easy to move around
    This chair is really comfortable. The seat cushion is soft but supportive, and the mesh back keeps my back cool during long workdays. The lumbar support helps a lot with my posture. What I especially like is how smoothly the casters roll — glides effortlessly on my floor, no noise at all. Assembly was quick, around 10 minutes. The flip-up armrests also help save space when pushing the chair under my desk. Great value for the price. Highly recommend for anyone needing a solid, comfortable home office chair.

    Great chair at a good price
    It's a great chair, comfortable and reasonably priced for an ergonomic office chair. I usually don't write reviews, but I also understand how purchasing an office chair can feel overwhelming with so many choices. I needed to replace the chair I'd purchased in 2020. At the time I'd not spent a lot of money, not sure if working remotely would be temporary or permanent. It lasted about as long as one might expect. I did quite a bit of research choosing a replacement. I'm always hesitant to purchase furniture without trying it out in person. This chair is worth the price, not on the higher end of what's available but definitely not cheap. I've had it for about three weeks and so far, it's perfect for the 8-10 hours I spend in it during the week. It arrived early, a great bonus. Assembly was quick, with easy-to-follow directions and all the tools and parts needed. (including some spare screws). I agree with others who mentioned that a spare set of hands would have helped, but I had no issue doing it myself. It's a sturdy chair with good lumbar support. The adjustability of that feature can accommodate different heights. (I'm around 5'4") Changing seat height or whether the back tilts or remains stationary are all easy to accomplish. The one minor caveat is the seat is leather, so in warm weather and shorts season, it's not ideal. I solved that by purchasing a cover (because of the way the chair fits together, I purchased one that covers both the seat and back because a seat cover by itself would not work). That has worked fine and I'm not sure whether I'll keep the cover on all year. Overall, it's a great chair at a good price.

    Comfortable and Great Value Office Chair
    This office chair exceeded my expectations for the price. The assembly was quick and easy, and the chair feels sturdy once put together. The seat cushion is comfortable for extended use, while the mesh back helps keep airflow moving throughout the day. I also like the adjustable lumbar support and flip-up armrests, which make it easy to customize and save space when not in use. It rolls smoothly, looks professional, and provides great comfort for working from home. Overall, an excellent value and a solid choice for a home office.
