Plain Cork MS113
Plain Cork MS113 is a plain cork sheeting bound with polyurethane and composed of 0.5 mm cork granules, designed for no-skid, no-scratch protection of ceramic and porcelain products, spacer applications, and shipping glass “loose-light.” It achieves compressibility of 35%–55% @ 100 PSI and recovery of ≥ 75% @ 100 PSI per ISO 7322, with a minimum specific weight of ≥ 160 kg/m³ and a tensile strength of ≥ 242 kPa (≥ 35.1 psi).

Common industries: Glass handling and distribution, packaging, construction / architectural glazing, office products, sound and vibration control.
Plain Cork MS113 is a polyurethane-bound plain cork sheeting composed of 0.5 mm cork granules, providing a lightweight, smooth-to-the-touch, no-skid and non-scratch surface suitable for protecting ceramic and porcelain products, filling glass channels, packaging applications, sound absorption, book binding, and cork bulletin board fabrication.
Its compressibility range of 35%–55% @ 100 PSI allows it to conform under load while its recovery of ≥ 75% @ 100 PSI ensures it rebounds after compression, maintaining consistent spacer thickness and protective function. The polyurethane binder holds the granule structure together through the full use cycle, including boiling water exposure, which produces no disaggregation per ISO 7322.
Recommended storage conditions are 20 ±3°C / 60 ±5% HR. Other cork grades are available by special request; longer lead times and minimum orders will apply.
What differentiates Plain Cork MS113 from other cork or rubber spacer materials?
Plain Cork MS113 is a polyurethane-bound plain cork sheeting composed of 0.5 mm granules, providing a natural, lightweight, smooth-to-the-touch surface that is simultaneously no-skid and non-scratch. Unlike rubber-based setting blocks or spacers, plain cork offers inherent compressibility (35%–55% @ 100 PSI) with high recovery (≥ 75% @ 100 PSI) in a material that will not mark, scratch, or damage delicate ceramic, porcelain, or glass surfaces on contact.
Why is compressibility an important property for cork spacer and protective pad applications?
Compressibility determines how much the cork will deflect under a given load, which directly affects how well it conforms to the mating surfaces it protects and spaces. A cork that is too stiff will not distribute load evenly, risking point contact damage; one that is too compliant will bottom out and lose its protective thickness. Plain Cork MS113 achieves a compressibility range of 35%–55% @ 100 PSI per ISO 7322, providing a controlled deflection range appropriate for glass, ceramic, and porcelain protection and spacing applications. The ≥ 75% recovery at 100 PSI ensures the material rebounds after load removal, maintaining consistent spacer thickness over repeated use cycles.
What are the recommended storage conditions for Plain Cork MS113?
Plain Cork MS113 should be stored at 20 ±3°C / 60 ±5% HR, as listed on the TDS.
Is Plain Cork MS113 suitable for wet or high-humidity environments?
The TDS states that Plain Cork MS113 shows no disaggregation when exposed to boiling water per ISO 7322, indicating that the polyurethane binder maintains granule integrity under wet conditions. No specific compliance standards for wet environment applications are cited on the TDS.
How should Plain Cork MS113 be specified?
Specify grade (Plain Cork MS113), thickness, dimensional tolerances, and finished format. Note that other cork grades are available by special request with longer lead times and minimum order requirements.
