What is 80A hardness?

The Shore A scale can range from parts that are flexible and soft in nature (0-40A), to semi-flexible and medium-hard (50-80A), to very hard and rigid (90-100A).

How hard is 70A durometer?

A 70A rubber (as hard as a car tire) is stiff and would not offer enough flexibility to extract this model without breaking it.

How hard is Shore 90a?

Shore A “0” denotes extremely soft, gel like materials such as silicones, while semi-rigid plastics will be measured at the highest end of the scale around 90-95A. Typical properties and applications: 90 Shore A materials are suited to machining compared to softer materials that can be ground.

What is 60A hardness?

c. Shore 60A = Car Tire Tread. d. Shore 70A* = Running Shoe Sole.

How soft is 80a?

Wheels rated between 80a to 83a are balanced between soft and hard, giving the rider the freedom of control, speed, and grip.

Which is harder 70 or 90 durometer?

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound. 70-durometer hardness should be used whenever possible as it offers the best combination of properties for most O-Rings applications.

What does 70 Shore A mean?

A 70A rubber (as hard as a car tire) is stiff and would not offer enough flexibility to extract this model without breaking it. A better choice would be a Shore 30A rubber or softer that would offer enough flexibility to easily extract the model.

How hard is 60 Shore A?

For example: 30 Shore A is much softer than 80 Shore A. Once a material reaches Shore 95 A, it will resemble a plastic over a flexible material regarding how it feels….Some D rated examples.

75 Shore D Hard hat (typically HDPE)
80 Shore D Cast urethane plastic
60 Shore D Golf balls
80 Shore D Paper-making rolls

What are 80A wheels good for?

Wheels rated between 80a to 83a are balanced between soft and hard, giving the rider the freedom of control, speed, and grip. These are popular for freeriding, downhill, sliding.

What does 80A mean for rollerblade wheels?

Multi-Surface
80A (Multi-Surface) – While still considered a multi-purpose wheel, 80A wheels are less grippy than 78A wheels and perform best on smoother rough surfaces, for example wood, or painted and sealed outdoor surfaces. They do not provide enough grip for sport courts, no matter the skater’s weight.
