NBR Tape

Two Side Tape Company is a manufacturer of Foam Backed Adhesive Tape made with NBR/PVC rubber foam backing, one-side pressure-sensitive adhesive, and a removable release liner. This adhesive-backed foam tape is used for cushioning, vibration damping, panel sealing, edge protection, and light industrial mounting on metal or plastic parts. The compressible foam carrier helps close small gaps, reduce hard-surface contact, and make assembly easier for equipment covers, appliance trims, cabinet edges, and die-cut gasket pads.

Product Overview

Foam Backed Adhesive Tape is built for assemblies where a soft, compressible layer is needed between two hard surfaces. It is not a solid Buna-N rubber strip and it is not pipe insulation wrap. The tape uses an NBR/PVC rubber foam carrier with a typical density range of 80-180 kg/m3, giving the backing enough softness to compress, recover, and keep better contact with uneven surfaces.

In real assembly work, this foam layer helps reduce minor impact marks, panel rattling, and small sealing gaps on metal housings, plastic covers, painted parts, powder-coated panels, and appliance components. The one-side adhesive coating is protected by a paper or PE film release liner, usually selected in the 80-120 gsm range for stable handling, slitting, and die-cut processing.

During application, the liner is removed and the tape is pressed onto a clean, dry surface. No liquid glue, curing time, or extra fastening is required. On stainless steel, typical reference peel adhesion can reach 8-15 N/25 mm, but final bonding still depends on surface energy, coating texture, pressure, dust, oil, and release agents. For ABS, PC, PVC, painted metal, stainless steel, or powder-coated parts, sample testing before volume assembly is a practical step.

Two Side Tape Company can supply this foam tape as master rolls, narrow slit rolls, straight strips, kiss-cut parts, washers, rectangular pads, and drawing-based die-cut foam pads. Standard slitting tolerance is typically +/-0.5 mm. Die-cut tolerance is usually +/-0.5 mm to +/-1.0 mm, depending on foam thickness, part size, tool design, and shape complexity.

Benefits

• Softer contact between parts: The foam carrier helps reduce scratches, tapping noise, and assembly stress when metal, plastic, or coated parts touch each other.
• Useful vibration damping: In reference assembly use, 3 mm foam tape compressed by about 25%-30% can help reduce minor rattling on equipment covers, metal doors, and appliance panels.
• Better sealing on uneven gaps: The compressible backing fills narrow spaces better than thin film tape. A working compression range of 20%-40% is usually recommended for stable sealing and foam recovery.
• Cleaner one-side placement: The release liner protects the adhesive layer before use and supports manual placement, jig-assisted application, and repeated assembly work.
• Flexible converting format: The tape can be slit from 5 mm width or converted into gasket strips, anti-rattle pads, spacers, washers, and die-cut foam pads.
• Practical material balance: NBR/PVC foam offers compression recovery, cushioning, and light moisture resistance. Heavy oil contact, rough surfaces, or low-surface-energy plastics should be checked with samples first.

How Does the Foam Backing Improve Cushioning and Vibration Control?

The foam backing works as a small buffer between two assembled parts. When the tape is compressed, the rubber foam carrier absorbs slight surface differences and reduces direct vibration transfer from one panel to another. A 2 mm to 5 mm thickness is often selected for appliance trims, plastic covers, and equipment edges. Thicker foam may be used when the assembly gap is larger. Too little compression can leave weak sealing contact, while too much compression may crush the foam and reduce long-term recovery.

Applications

• Metal cabinet door sealing strips
• Plastic panel cushioning pads
• Appliance trim and cover mounting
• Equipment edge protection strips
• Control box and access panel sealing
• Anti-rattle foam pads for assembled parts
• Display frame and housing support
• Die-cut spacers, washers, and gasket pads
• HVAC equipment panel edges, not pipe insulation wrapping

Where Should Foam Backed Adhesive Tape Be Used in Industrial Assembly?

Foam Backed Adhesive Tape is suitable for places where parts need soft contact, moderate sealing, light bonding, or repeatable cushioning. Common positions include equipment edges, plastic housings, metal doors, appliance frames, removable covers, and control panel joints. For production use, the main selection points are adhesive strength, foam thickness, compression ratio, liner release force, width tolerance, and surface compatibility. If the tape is applied to textured powder coating, oily metal, or low-surface-energy plastic, trial bonding should be completed before mass assembly.

FAQ

1. Is Foam Backed Adhesive Tape the same as pipe insulation tape?

No. This product is a one-side adhesive-backed foam tape for cushioning, sealing, vibration damping, edge protection, and mounting. It is not designed as pipe insulation wrap.

2. Can the tape be supplied as die-cut foam pads?

Yes. Two Side Tape Company can supply slit rolls, straight strips, washers, kiss-cut parts, rectangular pads, and drawing-based die-cut foam pads. Typical die-cut tolerance is +/-0.5 mm to +/-1.0 mm depending on material thickness and part shape.

3. What compression range is recommended?

A typical working compression range is 20%-40%. Too little compression may reduce sealing contact, while too much compression can crush the foam and reduce recovery.

4. Does the adhesive work on all metal and plastic surfaces?

The adhesive works on many clean metal, painted, and plastic surfaces. Typical peel adhesion on stainless steel can reach 8-15 N/25 mm, but coating texture, dust, oil, and surface energy can change the final bonding result.
