Description   Elastomers and rubber compounds are natural or synthetic polymers with a high degree of flexibility and viscoelasticity (elasticity). The products described on this page take the form of raw, unformed compounds used for molding and fabrication. Elastomers are usually thermosets that require vulcanization, but also include various thermoplastics.   Types   The GlobalSpec SpecSearch Database contains different material grades of elastomer and rubber...

Design TrendsTop

Q:
What new technologies are influencing elastomer and rubber material design?
20 answers
Answers:
Applications for which thermoplastic elastomers are replacing thermoset rubbers include seals, gaskets, hoses, flexible tubing, coated fabrics, boots on steering columns, sheeting, weatherstripping, conveyor belting, and air ducts in automobiles.
~Shamshad Khalid Ansari A, Engineering Consultant, Karachi, Pakistan
My impression is achieving a rubber material with well properties and no need of vulcanisation or small time of vulcanisation with high stability. Also will have high influence the silicon as far as can be an economical product.
~Ernesto Avedillo, Engineer, Barcelona, Spain
New technologies have helped to get the desired properties by choosing the right material or combination of materials.

Q:
From your perspective, which companies are creating the most innovative elastomers and rubber materials?
22 answers
Answers:
As per my knowledge, our vendor purchases " PU" materials from Dow.
~HASMUKH MEHTA, Engineer, AHMEDABAD, INDIA
It seems that Dupont, Dow, 3P and Dyneon are leading the innovation.
~Allen N, Marketing/Sales, Houston, TX
IRM - India Taihong - China Marine Fenders International - USA

Applications and UseTop

Q:
What are some of the applications you have used elastomers and rubber materials for?
40 answers
Answers:
We have isostatic press. Today we use neoprene and PU material in our rubber moulds. We purchased rubber mould from local vendors.
~HASMUKH MEHTA, Engineer, AHMEDABAD, INDIA
Anti vibration mounts, rubber to metal bonded components, marine engine mounts, pile driver mounts, road roller mounts, conveyor belt scrapers
~Eig E, Technical Support, Melksham, UK
For microfluidic devices - application and behavior as a flexible membrane in oscillating circuits, and methods for controlling fatigue.

Answers:
Rubber residue left behind after NR as rubber rich portion is removed. This residue contains a lot of bio chemicals of interesting chemistry and performance.
~SUBRAHMANIAN V, Faculty/Staff, CHENNAI, INDIA
We are using silicon rubber ring to hold load for some time.
~Vivek V, General Management, Pune, India
Particle pick-up and transfer belt bristles.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of elastomers and rubber materials?
12 answers
Answers:
Elastomer type was selected incorrectly because erroneously it was assumed that a contamination problem was caused by chemical interaction. Instead it was because of insufficient wear resistance. A chemically non-sticking material was chosen with high wear rate, whereas in this case a tough material was needed.
~Niels Van der Stappen, Engineering Consultant, Nijmegen, Netherlands
Mix Parafinic oil with Nitrile. They don't mix and the product exudes oil and has no possible solution. The complete product is wasted.
~Ernesto Avedillo, Engineer, Barcelona, Spain
Yes some years ago, some companies manufactured TIRES with some bad elastomers formulations.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
14 answers
Answers:
Engineered elastomer should be able to give desired properties by simple blending of different types. Without curing or cross linking should be processable like thermoplastics. Easy recycling.
~Manufacturing, Coimbatore, India
Odorless, smooth banding, facile filler dispersion, as good mechanical properties as ionomers, light weight, bright and beautiful colours
~SUBRAHMANIAN V, Faculty/Staff, CHENNAI, INDIA
It would be very beneficial if there was a lubricious seal material that would operate under load at temperatures greater than 500 degrees F.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using elastomers and rubber materials?
14 answers
Answers:
Let users be informed well about chemical properties of the elastomer (polymer) type itself. Beware of interactions (swelling). Think about needed resilience (dynamic and/or static). Test before you buy and test precisely.
~Niels Van der Stappen, Engineering Consultant, Nijmegen, Netherlands
Understand the technology of the material you are buying, there are a multitude of grades of elastomers and compounding ingredients available and not all apparently equal grades are interchangeable in a rubber compound.
~Eig E, Technical Support, Melksham, UK
With heightened awareness of environmental issues akin to the use and disposal of elastomers, I would only request the industry to continue to use rubber and at the same time, kindly devise suitable methods to reuse.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of elastomers and rubber materials?
16 answers
Answers:
Is a very common error try to use EPDM with all applications. EPDM is for water, Nitrile Rubber is for OIL and Natural Rubber is for abrasive mixtures in general. There are many more types of materials. Consult with an expert.
~Ernesto Avedillo, Engineer, Barcelona, Spain
Make sure you know in which environment the rubber materials are used. Alkalies, acids, water, steam, oil, temperature and so on. The more you know the easier it is to develop the right material the first time.
~Lars L, Research & Development, Ry, Denmark
We will have to explore the possibility of non- conventional activation methods like dielectric heating in the elastomer modification and application.
