In addition to hiding power, titanium dioxide also plays a vital role in enhancing the durability of paints. It acts as a barrier, protecting the walls from external elements such as UV radiation, moisture and pollutants. Titanium dioxide's high refractive index allows it to reflect harmful UV rays, preventing them from fading paint and retaining its vibrant colors for a long time. This UV resistance is especially important for facades that are exposed to sunlight throughout the day.

  • Polyvinyl Butyral Resin (PVB) is a solvent Resin synthesized by the acetal reaction of Polyvinyl Alcohol (PVA) and butyraldehyde in contact with coal.

    Because Pvb Resin itself contains a lot of hydroxyl groups, it can bridge with some thermosetting resins to improve the properties of chemicals and film hardness.

    Because PVB resin has the above excellent characteristics, it is widely used in adhesive safety glass intermediate film of automobile and building, rust cutting primer, baking paint, wood paint, printing ink, adhesive of electronic ceramics and printed circuit board, adhesive between metal and metal, between metal and plastic, modifier of hot-melt adhesive, iron dimension waterproof processing of textile, etc. A variety of new industrial applications are also continuously developed and applied.

    The general characteristics of PVB are as follows:

    The appearance of polyvinyl butyral (PVB) resin is white spherical porous particles or powder, and its specific gravity is 1:1; However, the filling density is only 0.20 ~ 0.35g/ml.

    Thermal properties

    The glass transfer temperature (TG) of polyvinyl butyral (PVB) resin ranges from 50 ℃ of low degree of recombination to 90 ℃ of high degree of recombination; The glass transfer temperature can also be adjusted by adding an appropriate amount of Plasticizer to reduce it below 10 ℃.

    Mechanical properties

    The coating of polyvinyl butyral (PVB) resin has good water resistance, water resistance and oil resistance (it is resistant to aliphatic, mineral, animal and vegetable oils, but not to sesame oil). PVB is widely used in printing inks and coatings because it contains high hydroxyl groups and has good dispersibility to pigments.

    In addition, its chemical structure contains both hydrophobic acetal and acetic ACID groups and hydrophilic hydroxyl groups, so PVB has good adhesion to glass, metal, plastic, leather and wood.

    Chemical reaction

    Any chemical that can react with secondary alcohol will also react with PVB. Therefore, in many applications of PVB, it is often used with thermosetting resin to bridge and harden with the hydroxyl group of PVB, so as to achieve the characteristics of chemical resistance, solvent resistance and water resistance.

    Of course, films with different characteristics (such as hardness, toughness, impact resistance, etc.) can be prepared according to different types of thermosetting resin and different mixing ratio with PVB.

    Safety properties

  • The hydrodynamic ribsa) provided in two directions on the air side face of the lip ensure higher sealing performance (higher sealing performance in both rotational directions of the shaft).
  • In conclusion, the rubber valve cover gasket, though a small part of the engine, has a significant impact on its overall health. Its role in maintaining a secure seal and preventing oil leaks cannot be overstated. As such, it is essential to understand the importance of this component and to prioritize its regular inspection and timely replacement. Remember, prevention is always better than cure, especially when it comes to the complex and expensive machinery that powers our vehicles.
  • Spark plugs, the tiny yet crucial components in internal combustion engines, play a significant role in igniting the air-fuel mixture, thereby converting chemical energy into mechanical power. They are the unsung heroes of the automotive world, and their suppliers hold a vital position in the industry's supply chain.

  • Oil seals are widely used as sealing devices for machines.

    JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
    However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.

    Therefore, this series of columns will summarize the following in order:
    • The structure, functions, and types of oil seals
    • How to select the right oil seal
    • Handling of seals, and causes and countermeasures for oil seal failure

  • In the intricate world of mechanical engineering, small oilIn the intricate world of mechanical engineering, small oilpivotal role, often overlooked ensuring that oils and fluids remain where they should be, preventing leakage and maintaining efficiency.

  • In conclusion, the A7TJC spark plug is a testament to the importance of selecting the right ignition component for your vehicle. Its specialized design, coupled with advanced materials and engineering, ensures reliable ignition, improved efficiency, and a smoother ride. It is a small but critical piece in the intricate puzzle of engine performance, playing a vital role in keeping your vehicle running at its best.
  • Overall, TC oil seals are a reliable and cost-effective solution for sealing oil and preventing contamination in various mechanical systems. Their dual-lip design, high-pressure resistance, and long service life make them the go-to choice for many industries and applications. Whether you are a mechanic, engineer, or equipment operator, TC oil seals offer peace of mind and confidence in the reliable performance of your machinery.

  • Even the slightest chip or dent can cause contaminants to infiltrate your oil seal. If there are any scratches on the shaft, a leak path may develop, allowing the lubricant to drip. To protect the shaft from damage, wrap it in a mesh rubber screen and store it vertically in its compartment. This way, it can be shielded from potential cracking.

  • In conclusion, shaft oil seals are essential components in machinery and equipment that help to prevent leaks, protect critical components, and ensure smooth operation. Their importance cannot be overstated, and proper selection, installation, and maintenance are key to maximizing their effectiveness and prolonging their lifespan. With the right seals in place, machinery can operate efficiently and reliably, delivering optimal performance and productivity.


  • The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.

  • Abrasion-resistant 
  • Single
  • The effectiveness of a spark plug is measured by its heat range, referring to how quickly it can dissipate heat. A spark plug that's too cold may not allow proper fuel combustion, leading to engine issues. Conversely, a spark plug that's too hot can cause pre-ignition, damaging the engine. Therefore, selecting the right spark plug for a specific engine is crucial.

  • One key aspect that sets performance spark plugs apart is their electrode configuration. Many feature a single, large-diameter electrode or an iridium or platinum tip, which not only withstands higher temperatures but also lasts longer than conventional plugs. This results in a stronger, hotter spark that ignites the fuel more effectively, enhancing combustion and thus, engine performance.
