Flexible Discs for Curves, Coatings and Scratch Uniformity

Sponge sanding discs are positioned as soft-flex discs in the disc sanding category, designed to improve contour conformity, reduce gouging risk, and enhance scratch uniformity. They are especially suitable for coatings, fillers, primers, wood surfaces, and slightly contoured parts requiring consistent finishing quality.
They are not for aggressive stock removal, but for making surfaces smoother, more uniform, and ready for coating—critical in pre-paint prep and cosmetic finishing.

Логика обработки

Soft Contact Redistributes Pressure

Standard paper discs concentrate pressure on curves and edges, risking gouging, burn-through, or deep scratches. Sponge discs use foam buffering to redistribute pressure into a more uniform contact area:

• Better contour conformity and scratch consistency;
• Gentler edge interaction with lower burn-through risk;
• Ideal for pre-paint finishing and scratch unification.

Конструкция основы и пределы применения

Smoother, Not the Fastest Removal Tool

• Плюсы: contour following, edge-friendly contact, strong scratch consistency
• Ограничения / пределы применения slower stock removal than hard-backed discs or belts; heavy defects should be removed first with standard discs/belts

Foam compresses under load—excess pressure increases heat, foam fatigue, and uneven scratch patterns (especially at high RPM)

Совместимость с оборудованием и условия работы

Orbital / Random Orbital Sanders—Controlled Pressure is Key

• Оборудование: orbital/random orbital sanders, selected handheld sanders
• Рекомендуемые условия: medium to low pressure, stable speed, continuous movement
• Attachment: primarily hook & loop; PSA options available upon request
• Note: dust extraction improves cleanliness and reduces loading (depending on structure)

Диапазон и рекомендуемое применение

Grit Strategy for Coatings and Contours

Типовые рекомендации

• P80–P120: initial leveling of filler/thick coatings (control pressure to reduce loading)
• P150–P240: intermediate finishing and scratch unification (most common)
• P320–P600: primer finishing and final pre-paint prep (appearance-first)

Почему выбирают нас

Sponge Performance Depends on Foam Density, Bonding and Batch Stability

Sponge disc performance depends on foam density/resilience, composite bonding, and abrasive distribution stability. Foam controls pressure distribution and edge behavior; bonding and abrasive control life and scratch consistency. We engineer for batch stability to make pre-paint prep repeatable.

Рекомендации по использованию и хранению

Avoid Over-Pressure—Let the Foam Work

• Use medium to low pressure with stable speed and continuous movement to avoid compressing the foam and creating heat/uneven scratches
• For fillers/coatings, use dust extraction and periodic cleaning to reduce loading
• Avoid heat and solvent exposure to prevent foam aging and bond failure
• Храните в сухом месте в тени; избегайте влаги и сдавливания; после вскрытия повторно герметизируйте упаковку
