Material Composition and Structure

The slab consists of approximately 93% ground natural quartz aggregate bound by 7% polyester resin matrix. Pigments and metallic oxides are dispersed to produce the characteristic blue veining that runs through the mass. Quartz particles provide a Mohs hardness of 7, while the resin contributes flexural toughness.

Typical bulk density ranges from 2.3 to 2.5 g/cm³, and water absorption is less than 0.05% by weight after 24‑hour immersion, meeting ANSI/ISA‑71.04‑1985 standards for non‑porous surfaces.

Mechanical Properties

• Compressive strength: 180–220 MPa (ASTM C170)
• Flexural strength: 45–55 MPa (ASTM C880)
• Impact resistance (Charpy): 2.5–3.5 J/mm (ASTM D256)
• Coefficient of thermal expansion: 25–30 ×10⁻⁶ /°C (ASTM E228)

These values enable the countertop to withstand typical kitchen loads, thermal cycling from hot cookware, and occasional impact without cracking.

Manufacturing Considerations for OEM Partners

Slabs are produced in continuous vacuum‑pressed lines that eliminate entrapped air, ensuring uniform density. The blue veining is created by injecting a colored resin slurry into pre‑formed channels before curing, allowing precise control over vein width and pattern repeatability.

Standard thicknesses are 20 mm and 30 mm; custom thicknesses up to 40 mm can be accommodated upon request. Edge profiles are CNC‑machined to tolerances of ±0.1 mm.

Typical Applications

The non‑porous surface resists staining from oils, acids, and pigments, making it suitable for food‑preparation zones where hygiene is critical. The consistent veining provides a visual identifier that aids in brand‑specific design language across multiple installations.

Common uses include hospital countertops, laboratory workstations, retail display fixtures, and high‑end residential kitchen islands where a durable, low‑maintenance surface is required.

Customization Options

• Veining intensity: adjustable pigment concentration from light to deep blue
• Background tone: white, gray, or beige quartz base
• Edge profiles: eased, bullnose, ogee, waterfall
• Surface finish: polished (gloss >80 GU), honed (gloss 10‑20 GU), or leathered

All customizations are quoted based on slab size, veining complexity, and required lead time.

Quality Control & Testing

Each batch undergoes slab‑wide ultrasonic inspection for internal voids, followed by surface hardness testing (Shore D) and chemical resistance checks per ISO 2812‑1. Dimensional flatness is verified with laser profilometry, ensuring deviation <0.2 mm over a 1 m span.

Test reports are available upon request and can be included in the technical dossier for project approvals.

Typical Technical Specifications

Values are representative; actual properties may vary with specific formulation and are customizable according to project requirements.
