PVC(Poly Vinyl Chloride) Sponge

PVC(Poly Vinyl Chloride) Sponge

Product Overview

PVC Sponge (SPON-C) is a porous sponge roller with an open cell structure. It has excellent elasticity, chemical resistance, absorbency, and appropriate hardness, and can be used for liquid cutting, absorption, and cleaning.

product characteristics

  • Excellent absorbency and breathability due to porous structure

  • Suitable for secondary processing such as cutting, sawing, and laminating

  • Maintains resilience even after shape deformation

  • Absorbs dust, particles, etc. without damaging the product surface

specific use

  • Absorption and removal roller for various liquids

    Used for absorbing etching solutions and washing water for printed circuit boards, developer, fixer, and washing water for automatic developers, washing water absorption after washing photosensitive resin plates, and oil removal rollers.

  • Spon Brush for HDD Cleaning

    Used in areas requiring complex shapes or precise cleaning due to protrusions on the roll surface.

  • Dehydration roller (dehydration)

    Dewatering rollers for separating various sludges and solids, and various squeeze rollers (for removal)

  • application roller

    Water supply rollers for optel printing, water supply rollers for preventing paper curling, ink rollers, full rollers, and various coating rollers

  • Conveyor rollers and squeeze rollers

    For roll-to-roll and horizontal/vertical copper plating (FCCL, lead frame, PCB)

product advantages

Excellent chemical resistance and cleaning power

  • Chemical resistance to acids, alkalis, and organic solvents (MEK, IPA, etc.) is superior to PO/PU.
  • Can be used without performance degradation even during repeated washing processes
  • Reduced equipment maintenance costs due to high reusability after cleaning

Suitable for electrostatic sensitive processes

  • PVC\'s unique insulating properties make it suitable for environments where ESD (electrostatic discharge) is important.
  • Simultaneous detection of foreign substances and surface protection possible in FPCB, OLED, and HDD manufacturing lines sensitive to static electricity induction.

Complex shape response

  • PVC material has excellent machinability and can be processed into various shapes such as embossing, profile processing, and brush roll structures.
  • It is harder than PU and has a medium stiffness that is more washable than PO, providing an excellent balance of precision processing and durability.
