Technical Specifications

Water Absorption Rates

Water absorption rate is a critical factor for materials used in outdoor settings. It refers to the percentage of water absorbed by weight when a tile is submerged. This specification is crucial as it affects the durability of the tile in various weather conditions. A lower absorption rate typically indicates a tile that is less prone to cracking in freeze-thaw cycles. The standard for water absorption is categorized into non-vitreous (high absorption), semi-vitreous, vitreous, and impervious (extremely low absorption).

Coefficient of Friction

The coefficient of friction (COF) is a measure of a tile's natural resistance to slip and is a critical safety aspect. Tiles with a higher COF will have better traction, reducing the risk of slips and falls. This is particularly important for tiles used in wet areas or in environments where safety is paramount. The COF is determined by the force required to slide an object over the surface divided by the object's weight. There are two types of COF: static (SCOF), which measures the force needed to start moving, and dynamic (DCOF), which measures the force needed to maintain movement.

Frost Resistance

Frost resistance is the ability of a tile to withstand freeze-thaw cycles without cracking or deteriorating. This is an essential characteristic for tiles used in climates that experience harsh winters. The frost resistance is determined by subjecting the tile to cycles of freezing and thawing in water. Tiles that survive without visible damage are considered frost-resistant. This property is often related to the water absorption rate, as lower absorption rates typically contribute to better frost resistance.

Load Bearing Capacity

The load-bearing capacity of a tile refers to the amount of weight the tile can support without failing. This is a crucial consideration for flooring tiles, especially in commercial or industrial settings where heavy foot traffic or equipment use is expected. The capacity is determined by the breaking strength of the tile, which is the force required to break a tile under a standardized test. The load-bearing capacity is influenced by factors such as the tile's thickness, composition, and the quality of installation.
