Flat Packing Pad — Moulded to Your Load and Gap
A plain moulded rubber pad that carries load and holds a gap — the closed shape, where a slot or an angle is not wanted. Specified on the load it takes and the deflection you can allow, not on hardness alone, because a pad’s stiffness comes from its proportions as much as its compound. EPDM as standard.

Available materials
Rubber Compound Options
Select the compound best suited to your operating environment and application requirements.
| Rank | Compound | Temperature | Why, for a flat packing pad |
|---|---|---|---|
| Recommended | EPDM | −40 to +140 °C | Weather, ozone, UV, water and steam, and it stays flexible cold. Creeps more than natural rubber under sustained load, so allow for it in the deflection |
| Recommended | Natural rubber | −20 to +90 °C | Where the pad carries sustained load. Best fatigue resistance, highest resilience and least creep of the eight, so the gap stays held. Not for oil, and it perishes in prolonged sunlight |
| Suitable | Neoprene | −40 to +120 °C | The compromise where the pad is both loaded and exposed — good fatigue life with reasonable weathering |
| Suitable | NBR | −30 to +120 °C | Where the pad sits in oil. Poor ozone resistance, so not for an exposed position |
| Suitable | SBR | −30 to +100 °C | Low-cost enclosed packing. Fatigue life below natural rubber and no oil resistance |
| Available | Silicone | −60 to +220 °C | High temperature. Low tear strength and poor fatigue resistance make it a weak choice under load |
| Not recommended | FKM · AEM | See the compound table | Expensive sealing compounds with no fatigue or creep advantage in a packing pad |

Key advantages
Why Specifiers Choose Margo
Every pad in every compound
The compound is not what makes one pad different from another — the shape is. Any pad in this range can be moulded in any of the eight compounds we mix, so tell us the duty and we will name the material.
Hardness will not tell you how it behaves
Rubber bulges rather than compresses, so a thin wide pad is far stiffer than a thick narrow one of the same compound. Send the load and the deflection you can allow, and we set the shape and the hardness together.
Weather or load — they pull apart
EPDM survives sunlight and ozone; natural rubber holds a gap without creeping. Where the pad is exposed and loaded we quote neoprene and explain the trade rather than defaulting to whichever we mixed last.
Holes moulded in, not punched after
Fixing holes formed in the tool are cleaner and stronger than holes cut afterwards, and the pad keeps its full section around them. Send the bolt pattern with the outline.
Industries served
Global Applications
Heavy industry
machine feet, shimming under gearboxes and bearing housings, anti-abrasion packing between metal faces
Automotive
bracket and body packing, anti-rattle spacing, protective pads between painted panels
Infrastructure
plant and equipment packing. Not structural bearings, which are certified separately
Agriculture
implement and cab packing on equipment worked and washed outdoors
Manufacturing process
From Compound to Certification
Material compounding
Polymer blending, additive integration and batch QC in our in-house lab. The compound is chosen for creep resistance first, since a packing pad has to hold its gap for years.
Mould Design & CNC
Mould design and CNC tool manufacture, in-house, held as a controlled record. Footprint and thickness are set together to reach the load and deflection, and fixing holes are formed in the tool rather than cut afterwards.
Compression Moulding
Compression moulding.
Post-Cure & Trimming
Post-cure and trimming, with adhesive backing applied where specified.
Quality inspection
Dimensional check, hardness, and load-deflection tested on batch samples against the approved drawing.
Export packaging
Industrial packing with documentation. Pads are packed flat and unloaded, since rubber stored under compression takes a set before it is ever fitted. ISPM-15 treated pallets where timber packaging is used.
Quality assurance
Certified to International Standards
Every product leaves our facility with a documentation package — material test reports, dimensional inspection sheets and a certificate of conformance — giving traceability from raw material to finished part.

Technical & Commercial Questions
Answers to the most common questions from engineering teams and procurement managers worldwide.
What is the minimum order quantity for this part?
We supply in bulk. The minimum run is 10,000 pieces per part number, per compound, or quoted against the part where geometry or tooling makes that unrealistic. Prototype and first-article lots sit outside the minimum.
Can you match a competitor specification or reverse-engineer an existing part?
Yes — but send the load as well as the pad. A pad taken out of service has crept and measures thinner than it was moulded, so copying its dimensions reproduces a part that is already part-worn. We work back from the gap it has to hold and what sits on it.
What file formats do you accept for drawings?
PDF, DWG and DXF. An outline with the bolt pattern marked is enough — add the load per pad and the deflection you can allow, and hardness becomes our output rather than your input. A 3D model is not required for a flat pad.
Do you provide material test reports with each shipment?
Yes. Material test reports, dimensional inspection sheets and a certificate of conformance ship with every consignment. Hardness, tensile to ASTM D412 and compression set to ASTM D395 Method B are tested in-house, and load-deflection is checked on batch samples against the approved drawing.
What are your payment and delivery terms for international orders?
TT and LC accepted, discussed per order. Ex-works Nashik or FOB Nhava Sheva. Commercial invoice, packing list and certificate of origin are issued with every consignment. Pads ship flat and unloaded.
