Measuring Shore Hardness for Materials

What Shore Means

Shore is the edge of land abutting on a sea, ocean, lake, or river. It can be sandy or pebbly, and may have cliffs. Other words with similar meanings include bank, beach, and coast.

Most thermoset resins display varying levels of hardness when cured, and determining the right Shore hardness for your application is essential. This is where a durometer comes in handy.

A shore is the part of a ship’s side or bottom that extends above the water line. It is also called a “leg,” and it is used to support the vessel when she is laid aground or on the stocks. Shores are also used to prop ships when they are floating in the ocean or other large bodies of water.

Shore hardness is a measurement of the amount of resistance that a material has to indentation. It is measured using a tool called a durometer, which uses a spring-loaded rod to compress the surface of the elastomer and provide a reading. The harder the material, the higher the durometer rating.

Hapco formulates a variety of liquid molding materials that display different levels of hardness and flexibility when cured. Depending on the application, it can be important to select the appropriate material for the job. For example, a soft rubber with a lower Shore hardness will be more flexible and will more easily demould fragile model parts than a stiffer material with a high Shore hardness value.


The shore, beach or coast is the edge of land that meets a body of water like an ocean, lake or river. It can be sandy or pebbly, rocky or grassy and can take many different forms. The shore is also subject to many environmental factors like waves, tide changes and erosion.

Not all beaches are sandy; they can be stony, gravelly, silty or clayey as well. Some even feature cliffs or reefs as part of the shoreline. Even though sand is the most common material found on beaches, there are actually a lot of rocky shorelines around the world as well.

There are many kinds of beaches because the sand is made from small pieces of rock that have been washed away by waves and currents. The shape and profile of a beach can change dramatically within a day, depending on the direction that sediment drifts and how big and destructive the waves are.


A shoreline is the land along the edge of a sea, lake or wide river. It is different from a coast, which must border an ocean. The shores of lakes and rivers can be rocky or sandy.

A natural coastline advances and retreats on time scales ranging from seconds to millennia. Understanding this dynamic nature of the shoreline is critical for coastal management and engineering design.

The FWC is leading a statewide effort to develop and teach a Living Shorelines training course for marine contractors. This green infrastructure technique uses a combination of nonstructural and structural approaches to stabilize estuarine beaches, bays and tributaries. The method uses native vegetation to control erosion, dissipate wave energy, provide habitat structure and enhance ecosystem services, like nutrient remediation. This is an alternative to the traditional use of ‘hard’ stabilization methods like seawalls. ‘Soft’ materials such as coir logs and oyster reefs are also used to add additional stability.


Cliffs are steep rocks that form the edge of a beach, lake or river. They can be formed naturally by erosion or by people.

Rocks that jut out of the sea at headlands are battered by waves from both sides, and over time the breaking waves wear away the rock at sea level, forming caves and arches. Softer rock erodes more quickly than harder rock.

In some places cliffs are fronted by shore platforms, which focus wave energy to reduce cliff retreat rates.[3] Pocket beaches also form in sheltered zones between headlands.

Cliffs provide a scenic backdrop and habitat for many species of plants and animals. They are particularly important for birds, which nest in rocky crevices and in trees on clifftops. Animals may also shelter from predators and from harsh weather by burrowing into the sand and rock beneath cliffs. The sand and rocks around cliffs are often rich in minerals. This material is sometimes used to make shingle and a range of other building materials.
