R&D

Yunslab produces the finest PVA products applying the world best technologies in this field.

R&D Trends

  • Porosity and the range of Pore size

    Porosity and the pore size determines the exceptional features of PVA sponge.
    Appropriate distribution of different pores and its porosity influences the cleaning quality of PVA sponge.

  • Mould design capability

    The biggest factor to decide the PVA functions.
    Shape and structure of Mould is essential to produce best quality PVA sponges.
    Often, mould design capability verigfy the level of technology of the company's R&D ability.

  • Recontamination

    Critical factor to manage the cleanness of wafer.
    The other crucial factor is preventing the recontamination by bonding with the detached particle during the cleaning process.
    The first reduction target to prevent recontamination is eliminating particles which are attached on the surface of brush body while cleaning.

  • Cleaning

    The cleanness of Wafer reflects the capability of PVA brush's cleaning power.
    Both organic and inorganic contaminated paricles should be eliminated.
    The structure of Yunslab PVA sponge has unique quality to get rid of any removable particles.

Technical Advances

  • Absorbency

    Absorbency is serious factor to manage the cleaning power of PVA sponge.
    Yunslab PVA products are well managed to retain the adequate and highest absorbency level.

  • Uniformity

    The vital point in cleaning is continuing stable balance of brush while spinnig.
    Yunslab PVA products are well made to have the stable balancing.

  • Recontamination

    The efficient separation of contaminated particles is the key point in managing the PVA cleaning quality.
    Yunslab applies its own know-hows to blocking re-adhesion of detached particles.
