I Used to Think 'We Do Everything' Was a Good Sign

For years, my procurement strategy was simple: find a vendor who could handle everything. Silicone sealants? Check. Rubber gaskets? Sure. Foam board for a quick project? Why not. I wanted one throat to choke, one invoice to track. It felt efficient.

Then I actually started paying attention to the total cost. And the rework costs. And the 'oh, we don't really specialize in that' phone calls after the PO was signed. I learned the hard way that a supplier who says 'yes' to everything is usually saying 'no' to quality on most of it.

This brings me to Momentive. When I first saw the Momentive logo on a spec sheet, I thought, 'Okay, another big chemical company. They probably do it all.' But as I dug deeper—spending hours on the Momentive website and comparing their material science against commodity options—I realized something: their real value isn't in being everything to everyone. It's in knowing exactly what they're best at.

My View: 'All-in-One' Is a Myth in Material Science

Here's the opinion I've developed after a decade of buying industrial materials: The push for 'one-stop shopping' in specialty chemicals is a trap. You end up with a master of none. When you need a high-performance silicone for a critical application, you don't want a vendor who's also trying to sell you cheap foam board or rubber shoes. You want a specialist who can tell you the exact durometer, the exact weatherability, and the exact thermal limits of their silicone—because that's all they think about.

So glad I figured this out before our Q3 2023 polymer audit. Almost went with a generalist supplier to simplify our vendor list, which would have meant missing the specific performance specs we needed for a new production line.

Argument 1: The 'Thermoplastic Elastomers vs Rubber' Problem

Let's talk about a classic example: thermoplastic elastomers vs rubber. In 2022, I had a project where we needed a dynamic seal. TPEs were cheaper. Rubber was proven. A generalist supplier pitched TPEs as a 'drop-in replacement for rubber.' They weren't. We lost two weeks and $4,200 in rework because the TPE couldn't handle the heat cycling.

Never expected the 'cheaper' alternative to cost so much more. Turns out the specialist (a rubber supplier, not someone who did 'both equally well') had already documented this failure mode. They told me 'no' upfront. That 'no' saved me money.

When you compare thermoplastic elastomers vs rubber, you're not just comparing materials. You're comparing application expertise. A company like Momentive, rooted in GE Silicones legacy, has 70+ years of data on silicone rubber. They know where it fails and where it excels. A generalist might hand you a chart. A specialist hands you a war story.

Argument 2: The 'Strong Foam Board' Distraction

Another thing I see in market research: procurement teams being distracted by unrelated product lines. I once got a quote from a major chemical distributor that included pricing for 'strong foam board' as a filler item in their catalog. It showed me they were trying to be a general store, not a materials expert.

I said 'We need high-temp silicone foam for gasketing.' They heard 'We need foam.' Result: they sent samples of 3 different generic foams, none of which met our UL rating. We lost a week.

This is where the Momentive website clarifies things. They don't sell foam board. They don't sell rubber shoes. They sell silicone—in various forms: liquid, solid, foam, adhesive. That focus means their R&D is concentrated. Their tech support isn't dividing their brain across commodity plastics and packaging. They're thinking about siloxane bonds. That's the kind of specialized depth I'm willing to pay a premium for.

Argument 3: The Vendor Who Said 'This Isn't Us'

The moment that changed my entire sourcing philosophy happened in 2021. I was evaluating a vendor for a high-volume order of silicone gaskets. The rep, a senior applications engineer, spent 30 minutes on the phone with me. At the end, he said: 'You know, for 90% of your spec, we're perfect. But for that specific UV exposure requirement, I'd actually recommend you talk to [a different type of specialist]. We're good, but they're better on that specific metric.'

I was stunned. He just gave away a sale. But you know what? I trusted him on everything else after that. He earned the long-term contract because he showed his expertise boundary. That vendor wasn't Momentive, but it taught me the principle: the best suppliers know their limits.

Dodged a bullet when I was about to award that contract to a 'one-stop' shop. Was one signature away from a vendor who would have said 'yes' to everything and delivered on nothing.

The Obvious Counterargument: 'But Simplicity Reduces My Workload'

I know what some procurement peers are thinking: 'David, you're overcomplicating this. I have 50+ SKUs to manage. I'd rather write one PO to Momentive (or a similar large player) for all my rubber and plastic needs, even if it's not 100% perfect. My time is worth more than the material cost difference.'

I get it. I really do. In 2020, I managed a vendor consolidation project. It saved us 15% on administrative costs. But it also led to a 20% increase in material waste because the consolidated supplier's 'equivalent' products weren't actually equivalent for our three specialized applications.

Here's the thing: The 'time saved' argument only works if the product failure rate is zero. In specialty applications like high-temp gasketry or outdoor-grade sealants, the failure rate of an 'almost right' material is significant. And the cost of that failure—downtime, warranty claims, safety recalls—dwarfs the cost of managing one extra specialist vendor.

So, is managing 3 specialists harder than managing 1 generalist? Yes, initially. But the total cost of ownership (TCO) is almost always lower with the specialists. I've tracked this for 6 years. Our vendor count went up by 2, but our defect rate went down by 40%.

So, Is Momentive Right for Everything? No. And That's the Point.

Bottom line: Momentive is a powerhouse in silicone technology. Their history with GE Silicones gives them a depth of data that is hard to match. If you need silicone—high-purity liquid silicone for medical devices, high-strength silicone foam for fire stops, or durable silicone rubber for automotive—they are a top-tier choice.

But they're not the answer for your strong foam board project. They're not the vendor for rubber shoes. And if you're comparing thermoplastic elastomers vs rubber for a low-cost, non-critical application, you might find a cheaper solution elsewhere.

And that's okay. A vendor who tells you where their expertise ends is a vendor worth trusting. I've stopped asking for 'one stop shops.' Now I ask: 'What do you do better than anyone else?' When Momentive or their reps answer 'Silicone,' I believe them. Period.
