Rubber strip material
 

EPDM
Ethylene propylene diene monomers, or EPDM, is a synthetic rubber. More specifically, it’s an elastomer, meaning that it has elastic properties. It’s often referred to as ‘EPDM rubber’ due to its similarities to rubber. This makes it ideal for gaskets and seals. Along with its flexibility, it also resists heat and chemicals. Popular sealing profiles in: Automotive, machinery, generators and HVACs, medical devices, electronics, double-glazing window seal and construction.

 

Rubber
Generally, rubber is compatible with acids and alkalis, but some rubber seals and gaskets do not stand up well to petroleum fluids. Still other rubber profiles are excellent at standing up to high temperatures. All that said, rubber is excellent as a seal to prevent leaks.Popular sealing profiles in: Automotive, industrial machinery pumps and valves, and medical-device seals

 

Closed-cell foam
Common foam materials include polyethylene, polyurethane, neoprene, nitrile and PVC. Two layers of the material are bonded by adhesive tape. These types of gaskets usually cost more than others, but for damping vibration, reducing noise and providing insulation, you can’t do much better.Popular sealing profiles in: Electronics, enclosures and construction

 

PVC
Polyvinyl chloride, known as PVC, is available as either rigid or flexible. Obviously for sealing profiles, it’s all about flexibility. Sealing profiles made with PVC resist UV, so they’re especially good for outdoor applications. PVC also absorbs shock and reduces noise.

Process of Rubber Strip
 

Calendering

The calendering process is the most widely used as it is an adaptable and flexible way to manufacture rubber strip sheeting. Calendered Rubber strip can be made from a variety of different rubber strip compounds of different types and hardnesses. It is made in dimensions ranging from 0.1 to 12 mm thick and up to 3 m wide. All of these variations are possible by adjusting the settings on the calender, rather than having to fit different tooling.For the uninitiated, the calender is like a giant mangle. It has a series of large horizontal parallel steel cylinders or ‘bowls’ that the rubber strip is fed through. The gap between these steel bowls is accurately controlled and as the rubberstrip is fed through this gap it is formed into a sheet of a designated thickness. This continuous and linear process enables large quantities of rubber strip sheeting to be manufactured cost effectively.

Extrusion

The next most prevalent forming process employed is extrusion. An extruder is like a sausage machine in an old-fashioned butchers’shop. Sausage meat is fed in one end, travels through the machine on a screw as a handle is turned. The meat is forced out the other end through a head that shapes the meat into a sausage. This basic principle can be applied to rubber strip sheeting but the extruder is somewhat larger and the process and controls more complex.Rubber strip compound (usually in a continuous strip format) is fed into the end of the extruder and travels through the barrel on a motorised screw. Whilst in the barrel the rubber strip is warmed and mixed under high shear before it is forced through the extruder head.

Press Moulding

The last method of manufacturing rubber strip sheeting to consider is press moulding. Presses come in a variety of shapes and sizes. They are responsible in some cases for shaping and curing the sheet in a single process. Broadly speaking, presses can be categorised as large and small. Small presses with beds a few square metres or less can be used to produce single rubber strip sheets every cycle.

Installation and Maintenance Tips for Rubber Strips

 

 

Installing rubber strips correctly and maintaining them properly are crucial steps in ensuring their optimal performance and longevity. Here’s a concise guide to help you with the installation and maintenance of rubber strips:

 

Proper Installation
During installation, ensure that the rubber strip is clean and free from any contaminants that could affect its performance before trimming to your desired length with a sharp blade. If you’ve opted for a self-adhesive rubber strip, peel back the paper and securely fix to your designated surface. For non-adhesive rubber strips, we recommended a high-quality contact adhesive such as Thixofix.

 

Check Surface Compatibility
Before installation, assess the compatibility of the rubber strip with the surface material. Some adhesives or surfaces may require priming or additional preparation to ensure proper adhesion. Confirm that the surface is clean, dry, and free from oils or other substances that could compromise the bond.

 

Proper Sealing
If the rubber strip is used for sealing purposes, ensure that it creates a tight and effective seal. Verify that the strip is correctly positioned to prevent gaps or overlaps, which can compromise its sealing capabilities. Pay attention to corners and joints, as these areas are critical for maintaining an effective seal.

 

Cleaning and Maintenance
Keep the rubber strip clean to ensure its continued effectiveness. Depending on the application, regular cleaning with a mild detergent or solvent may be necessary. Avoid harsh chemicals that could degrade the rubber material. For outdoor applications, consider UV protectants to prevent deterioration due to sunlight exposure.

 

Replace Worn or Damaged Strips
If you notice signs of wear, damage, or a decline in performance during inspections, don’t hesitate to replace the rubber strip. Continuing to use a compromised strip can lead to further issues and compromise the intended functionality.
