Why Buna N is so popular for use with hydrocarbons

We love a novel material at Martin’s Rubber; something that has been specifically developed to do a very challenging job under a range of unusual conditions. However, our objective is never to reinvent the wheel or overengineer things unnecessarily. There are some fantastic rubbers already on the market that work perfectly for many industrial applications – and Buna N is one that has been around for nearly a century and really pulls its weight as a veteran of materials. But it’s important to understand what a material is good at and why. If you’re looking at a rubber compound suited to contact ..read more

Bianca has joined us in the role of Sales Support, taking on customers within our processing and manufacturing industries as an internal representative and the first point of contact as people get in touch or need support with enquiries and orders. I sat down with Bianca over a Teams call to get a better understanding of what drew her Martin’s, how she has found her first 6 weeks with the company and what her biggest challenges have been so far. Bianca’s background lies in customer service, with a career starting in South Africa in the hospitality industry and then moving to the UK and into B2 ..read more

High temperature grades of rubber
Martins Rubber
by Claire Clarke
10M ago
The increasing demands of new technologies, particularly those being developed for aerospace, UAVs, electric vehicles and in the energy sector, mean a greater need for seals and other rubber components be made from materials which are resistant to high temperatures. What do we mean by ‘high temperature resistant’? The first thing to clarify is that high temperature resistance in rubber is not the same as fire retardancy; the requirements are very different and therefore the additives used in the compounds are also different. Fire retardancy in rubber means that the material will not release no ..read more

AS9100 for SMEs: an expensive tick-box or the road to success?
Martins Rubber
by Claire Clarke
1y ago
Our quality manager describes AS9100 as ‘ISO9001 on steroids – but in a good way’. AS/EN9100 is a quality standard used within the aerospace, space and defence industries; developed by the giants of aerospace, it was designed as a kind of insurance policy, with standardised requirements that they all agreed they wanted to roll out to their contractors and onward throughout the supply chain. With a greater focus on risk-based thinking, AS/EN9100 forces the business to focus on areas of weakness, strengthening them and slowly pushing all parts of the business to perform with greater consistency ..read more

Michelle has a background in two areas; she has spent time as a Security Officer, where she enjoyed working with the public, and prior to that and again more recently, in a customer service role in a B2B (business-to-business) environment. Michelle has NVQs in administration and customer service, and says that the most important thing for her, whatever role she’s in, is to be working with people. Michelle has joined the team at Martin’s Rubber that looks after our aerospace and defence customer base, working alongside Sales Managers Steve Rubery and Martyn Johnson. She is responsible for provi ..read more

How to test the quality of rubber
Martins Rubber

Have you ever had the o-ring on your garden hose split and leak everywhere? Annoying, isn’t it? If your first thought is that it’s due to a poor quality of rubber, think again. Many o-rings are made from NBR (nitrile), because the large majority of o-rings are used in applications to seal against oil – which NBR excels at. Unfortunately, it also degrades quickly in sunlight. Not a poor rubber quality, then – just the wrong material for the hose application. We take a more detailed look at what we mean by rubber quality and how to test the quality of rubber. What do we mean by rubber quality? B ..read more

How do you find the tensile strength of rubber?
Martins Rubber
by fahima.miah
2y ago
Tensile strength is one of the key factors that should be considered when selecting the right material for any application, in particular where a rubber component plays a part in sealing, supporting or anti-vibration. Tensile strength is often one of the main priorities in terms of material properties because it influences the performance of a product, especially where that product is likely to be under tension. We take a look below at how you can find the tensile strength of rubber, which factors influence tensile strength, and how it relates to FEA simulation.   Why is the tensile ..read more

How does FEA calculate stress?
Martins Rubber
by fahima.miah
3y ago
We’re all now pretty familiar with the kind of stress that can make you want to throw your laptop out of the window following a frustrating Zoom call – we can’t really help with that (although we promise a video call with us won’t end that way!) However, stress in engineering components can result in their premature failure.  Stress refers to forces acting upon the component, and strain describes how that component deforms relative to its undefined state in response to the stress. You may want to know whether the rubber material that you’ve selected for a design is up to the job. If so, i ..read more

What is nonlinear FEA?
Martins Rubber
by fahima.miah
3y ago
We often get asked what the difference is between linear and nonlinear FEA. Linear FEA is the perfect tool for the job it is designed for. But it is much simpler than nonlinear FEA.  Picture this: it’s Saturday lunchtime, you’ve spent the morning working out – a run, a swim, hell, let’s make it a triathlon. You need to eat something substantial but you are short on time. You grab a pre-made lasagne from the fridge and read the instructions; you pierce a few holes in the lid, check your microwave’s power rating and shove it in. Bing! Sorted. That’s linear analysis. Perfect for the job it w ..read more

Rubber by Royal Command

As an engineer, it’s not every day that you get asked to solve a problem for the most senior members of the royal family, particularly when that request results in an invitation into the Queen’s private chambers. Okay, so Her Majesty wasn’t present at the time – but it makes for a pretty good anecdote. The lucky man in question was Brian Hooper, the late father of Adam and Paul who run Martin’s Rubber. Here, Adam recounts the story his father told of the time he was called aboard the Royal Yacht Britannia to solve two rubber-related problems for Prince Philip and the Queen.
