What is Durometer? – Elastomer and Plastic Hardness

Materials Miscellaneous February 18, 2020

Durometer affects what type of materials and fittings you use for your application

What is durometer?

Durometer or Shore durometer is a standardized way to measure the hardness of materials like rubber (elastomers) and plastics. Durometer measurement scales range from 0 to 100 but there is no such thing as a durometer unit of measurement. Another way of saying this is that durometer is a dimensionless ...

What is Acetal Plastic? — POM Plastics for Flow Control Parts

Materials September 9, 2019

Why Acetal or POM plastic might be the best material choice

What is Acetal Plastic?

Acetal plastic also called polyacetal and polyoxymethylene (POM), is a general-purpose, semi-crystalline, engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction, and have good dimensional stability. Dimensional stability is the ability of a plastic part to maintain its ...

About Stainless Steel Materials – The Why and The How

Materials March 6, 2019

Why use stainless steel valves?

Stainless steel is a common material option for miniature flow control valves.

One reason for this is that stainless steels, like other metals, tend to be heavier but also stronger and tougher than plastics. Stainless steel materials, in particular, also have great corrosion resistance.

This blend of corrosion resistance and toughness is a ...

Stainless Steel Materials for Miniature Flow Control Valves

Check ValvesMaterials Miniature Valves November 29, 2018

Why stainless steel?

Stainless steel is a steel and so it is typically very strong. This gives it great pressure and temperature resistance. It is also a tougher, more durable metal than cast iron, ductile iron, brass or copper.

Stainless steels get their name from the fact that they are very corrosion resistant. This plus toughness and strength make them a preferred  ...

A look at the brasses used to make miniature ball and check valve bodies

Brass miniature valves are useful, reliable and economical
Wrought brasses, alloys of copper and zinc, are frequently used as the body material for metal mini check valves and ball valves. A major reason for this is brass performs well at temperatures ranging from about -325 to 425 °F (-198 to 218°C).

Equally important, the brass alloys used to make valve bodies can be quickly and accurately shaped using automated machining techniques. The result is that  ...

Some guidelines for selecting the right material for your application

This is the first in a new series of ISM blog posts about miniature valves and ball valves in particular.

Why use a ball valve?
Ball valves are durable, reliable and securely shut off flow even after sitting idle for long periods of time. Because of this, they are frequently used as fluid and gas flow cut-off valves. Ball valves are also easy to operate. This plus their availability in a range of useful material options has led to ...

Elastomers and Rubbers - Is There a Difference?

Materials December 5, 2016

Elastomers and rubbers are handy because of their unique material properties

Rubber and elastomer are words commonly used to mean any material with rubber-like properties. Elastomer is shorthand for elastic polymer. Elastomers are viscoelastic: sticky, very elastic polymers (plastics). Natural rubber is an elastomer made from latex, a milky tree sap. Synthetic elastomers are made from petroleum. Rubber is frequently used to indicate elastomers that must be vulcanized or cured to be useful ...
