Can ABS insulating edge strips be used in communication equipment?

Hey guys, it’s Jake from the ABS insulating edge strips supplier, and I get asked this question all the time from clients in the comms gear space—“Can your ABS strips even hold up in our communication equipment setups?” Let me cut to the chase right out the gate: short answer is yes, but let’s break down why that’s not just a generic “yes” and how we’ve actually seen these strips perform in real comms hardware over the last few years. No corporate jargon, just the stuff I see when I’m chatting with engineers, walking through our warehouse, or troubleshooting a last-minute order for a cell tower client. ABS Insulating Edge Strips

First off, let’s get on the same page about what these ABS strips actually do, because if you’ve never worked with them before, you might be thinking “just plastic trim.” For those of you who know, ABS (acrylonitrile butadiene styrene) is that tough, rigid thermoplastic that’s used for everything from Lego bricks to appliance casings—so it’s durable by default, but the insulating part is key here. When we make edge strips for comms gear, we’re talking about parts that go along the edges of circuit boards, backplanes, rack enclosures, or even the edges of fiber optic adapter plates. Their whole job is to keep conductive parts from touching each other, right? No short circuits, no signal bleed, no accidental electrical arcing that can take a whole network node down. That’s the baseline function, and ABS nails that way better than a lot of people assume.

Now let’s talk about comms equipment specific stuff—this is where the rubber meets the road, so to speak. Comms gear lives in some brutal environments, whether it’s a cell tower out in the Arizona desert baking in 115°F heat, a rural switch in a damp basement that never gets climate control, or a server rack in a busy data center that’s cycling power on and off 24/7. I’ve had clients tell me they tried cheaper insulating strips at first—like generic PVC or even some flimsy acrylic stuff—and they fried in under a year. ABS? We’ve had strips on the same cell towers I mentioned that are still going strong 5+ years later. Why? Because ABS has great thermal stability. Its glass transition temp is around 220°F, so at the temps comms gear usually operates at (most are rated for 104°F continuous), it doesn’t warp, soften, or lose its insulating properties. That’s a big one—if a strip warps even a little, it can pull away from the conductive parts it’s meant to separate, and suddenly you’ve got a problem.

Wait, but what about electrical insulation specifically? This isn’t just “doesn’t conduct electricity” — comms equipment needs consistent, reliable dielectric strength to pass regulatory checks (I’m looking at you, UL and IEC ratings, which are non-negotiable for most clients). Our ABS strips have a dielectric strength of like 20 kV/mm, which is way higher than the minimum required for low-voltage to mid-voltage comms hardware. I tested a batch last year for a client that makes 5G small cells—they needed strips that could handle up to 12 kV of potential difference between adjacent power traces, and our strips didn’t break a sweat. No arcing, no leakage current, just steady insulation. That’s the kind of hard data that makes engineers stop and go “oh, okay, this actually works for what I need.”

Another big thing in comms gear is resistance to dust and moisture, right? Small cell sites, outdoor DAS (distributed antenna system) components, even some desktop comms adapters get exposed to the elements. ABS has a low water absorption rate—like less than 0.3% by weight over 24 hours of submersion. That means it doesn’t soak up water, which would reduce its insulating ability and eventually cause corrosion on the metal parts it’s sitting next to. I had a client in Australia hit me up last year because their old strips were rusting and causing signal dropouts in a coastal DAS. We sent them a sample of our UV-stabilized ABS strips (we can add that stabilization as a custom tweak, by the way) and they swapped ’em out, and the signal issues were gone within a month. That’s not a small win—signal dropouts mean lost revenue for telecom providers, so fixing that with a simple strip swap is huge.

But wait, let’s not pretend ABS is perfect for every comms application. I’ll be real with you—if you’re working with high-voltage comms gear, like power line communication (PLC) equipment that runs at 100 kV or higher, ABS might not be the best pick. We actually recommend cross-linked polyethylene (XLPE) for that stuff, because it has higher dielectric strength for super high voltage. But for 90% of the comms gear out there—5G small cells, fiber optic patch panels, server backplanes, network switches, rack mount enclosures—ABS is a total workhorse. I’ve also seen it used for edge protection on edge computing modules, which are a huge part of modern comms infrastructure now—those little boxes at the edge of a network need tough insulation that can handle vibration too, right? Server racks vibrate from fans, trucks rumble past outdoor cell towers, ABS has good impact resistance, so it doesn’t chip or crack if something gets bumped into it. That’s way better than brittle materials that fail at the first little knock.

Now, let’s talk about how we tailor our strips for comms clients, because one size doesn’t fit all. I don’t just send a generic strip and cross my fingers. A lot of comms engineers have super specific needs: maybe they need a strip with a thin profile so it doesn’t take up too much space on a crowded circuit board (we can make ’em as thin as 0.5mm), or maybe they need a color-coded strip to mark different voltage zones (we color them with heat-stable pigments that don’t fade even after years of sun exposure), or they need a flame-resistant version (ABS can be formulated to meet UL 94 V-0, which is the highest flame resistance rating for thermoplastics—critical in data centers, where fires spread fast and are devastating). We also work with clients on custom lengths—some need 10mm strips, some need 1000mm, whatever they need to fit their exact design. No minimum order for small custom batches, by the way— I know startups and small comms gear makers can’t afford to buy 10,000 strips when they’re testing a new prototype, so we keep our minimums low.

Wait, let’s throw in a real quick anecdote to make this concrete. Last year, a startup that makes industrial IoT gateways hit me up. They were having issues with their prototype gateways shorting out during environmental testing—they were cycling between -40°F and 150°F, and the generic PVC strips they were using would contract or expand too much, pulling away from the power traces, leading to shorts. They tried our ABS strips, and we actually adjusted the thickness and added a little texture to the edge so it would grip the PCB better. They ran the testing again, and not a single short. They ended up ordering 50,000 strips for their production run, and now they’re a repeat client. That’s the stuff that matters—solving real problems, not just selling a plastic strip.

Let’s also address a common myth I hear: “Plastic is plastic, so it’s all the same.” No way. We source our ABS resin from reliable manufacturers, not the cheap stuff that’s full of fillers that break down over time. We test every batch for dielectric strength, thermal stability, and dimensional accuracy—if a strip is even 0.1mm too short, it’s useless for a PCB edge. A lot of smaller suppliers cut corners on that testing, which is why their strips fail. We don’t do that. Because when a client’s comms gear fails in the field, it’s not just their problem—it’s a bad look for our product too.

So to circle back to the original question: yes, ABS insulating edge strips absolutely work in communication equipment, for the vast majority of applications. They check all the boxes: consistent insulation, thermal stability, resistance to moisture, dust, and vibration, flame resistance when you need it, and customizable to fit your exact design. The only time they’re not the right pick is for super high-voltage comms gear, and even then, we can point you in the direction of materials that work for that.

If you’re working on a new comms project—whether it’s a prototype, a small production run, or a full-scale rollout—and you’re tired of insulating strips that fail, or you’re just not sure what material to use, hit us up to talk through your needs. We don’t do pushy sales talk—we just give you the straight scoop on what works, what won’t, and how our strips can fit into your design. No hidden fees, no weird minimums, just a reliable product that’s built for the demanding world of communication equipment.
