Pet pads come in 40 cm x 60 cm, 56 cm x 56 cm and 60 cm x 90 cm sizes with a leak-proof PE backing and a built-in attractant.
This technical bulletin addresses the Pet Care Pads range for laboratory environments requiring consistent absorbency, low particulate shedding, and supply chain resilience. Measured absorbency capacity is 320 mL per pad. Surface wicking time is ≤1.8 seconds under ISO standard test conditions. Particulate emission during unrolling and placement is <450 particles ≥5.0 µm per cubic meter in a Class 7 cleanroom chamber. These parameters directly support contamination control objectives where personnel handling frequency and proximity to sensitive assays demand predictable consumable behavior.
Material Architecture and Contamination Control
Pet Pads use a three-layer nonwoven composite: topsheet of spunbond polypropylene (18 g/m²), acquisition/distribution layer of airlaid cellulose-polymer blend, and a bottom barrier film of coextruded PE/PP (23 µm). The topsheet undergoes electrostatic treatment to enhance liquid strike-through without surfactants. In practice, this reduces pooling risk during intermittent flow events typical in animal housing monitoring stations. No adhesives or dyes are used in the core structure — only FDA-compliant polymer additives for hydrophilicity and thermal stability.
The barrier film exhibits water vapor transmission rate (WVTR) of 12 g/m²·24 h at 38°C/90% RH. This balances containment integrity with breathability for prolonged use in ventilated enclosures. Laboratory technicians report fewer instances of condensation-related slippage when pads remain in place for >16 hours. We typically observe <0.3% edge delamination after 72 hours of static load testing at 25°C and 60% RH.
Supply Chain Verification Protocol
Procurement specialists must verify batch-level conformance through KOSA Medical’s documented quality management system. Each shipment includes a Certificate of Conformance referencing ISO quality management principles and CE marking requirements. Buyers should request lot-specific test reports for absorbency volume, wicking time, and barrier integrity — not generic product brochures. These reports must include instrument calibration dates and operator signatures traceable to internal audit logs.
Verification requires cross-referencing lot numbers against KOSA Medical’s secure portal. No external certification body issues approval; conformance is declared by KOSA Medical based on internal validation protocols. Laboratories must retain these records for their own regulatory review cycles. Third-party audits may request access to production run logs and raw material certificates upon notice.
Comparative Performance Matrix
The following table summarizes performance across three configurations within the Pet Care Pads family:
| Parameter | Standard Pet Pads | Low-Particulate Pet Pads | High-Absorbency Pet Pads |
|---|---|---|---|
| Absorbency (mL) | 320 | 280 | 410 |
| Wicking time (s) | 1.8 | 1.4 | 2.3 |
| Particulates ≥5.0 µm (per m³) | 450 | 110 | 580 |
| Barrier thickness (µm) | 23 | 25 | 23 |
This matrix shows trade-offs between particulate control and absorption capacity.
Engineering Trade-off and Operational Limits
The Low-Particulate Pet Pads variant achieves its reduced emission profile at the cost of 40 mL lower absorbency versus Standard Pet Pads. This trade-off reflects tighter fiber bonding and reduced air-laid layer porosity. It is appropriate for laminar flow workstations adjacent to PCR prep areas but unsuitable for high-volume fluid exposure scenarios such as post-surgical recovery enclosures. Users should not deploy it where sustained saturation exceeds 200 mL/hour over >30-minute intervals.
For applications involving caustic cleaning agents or repeated autoclave simulation cycles, this selection does not apply. It also avoids use in sterile compounding suites where ISO quality management requires validated sterility assurance levels — Pet Pads are not intended for terminal sterilization. The design limits compatibility with ethylene oxide processing due to residual monomer migration risks.
Integration with Adjacent Product Systems
Laboratory workflows often require coordinated consumable deployment across animal care and human clinical support functions. For example, staff managing rodent colonies may transition from Pet Care Pads to Incontinence Care Products during shift handovers in shared biocontainment zones. Similarly, barrier film chemistry matches that used in Protective Apparel & Masks, enabling consistent chemical resistance profiles when disinfectants contact multiple surfaces.
- Surface energy compatibility tested against 70% isopropyl alcohol and 0.5% sodium hypochlorite
- Thermal stability verified from −20°C to +60°C for storage and transport
- Roll packaging dimensions standardized to fit existing dispensing hardware in ISO Class 5–7 labs
Measured tensile strength retention remains ≥92% after 14 days of continuous exposure to 40% relative humidity at 30°C. This supports extended shelf-life planning without refrigeration. Engineers responsible for facility-wide consumable harmonization should prioritize this data when aligning procurement across Pet Care Pads and other KOSA Medical hygiene lines.
Common questions on pet care pads
What makes a pet pad different from an underpad?
The construction logic is the same — absorbent core, leak-proof back sheet — but the sizing, the attractant and the surface pattern are aimed at animals rather than at bedding protection in a care setting.
How do buyers evaluate absorbency for pet pads?
By capacity per pad, by how quickly the surface dries after a wetting, and by whether the backing leaks at the seams when a full pad is lifted. Odour control is usually part of the same evaluation.
