Double Sticky Tape Company is a Solid Neoprene Rubber Strip manufacturer supplying dense CR rubber strips for gasket cutting, edging, spacer strips, wear pads, and mechanical protection parts. This solid neoprene strip is selected by Shore A hardness, tensile strength, elongation, compression set, and cutting tolerance rather than simple softness. It can be supplied in roll stock, sheet material, slit widths, cut-to-size parts, adhesive-backed strips, or non-adhesive rubber strips for industrial assembly.

Product Overview
Solid Neoprene Rubber Strip is used where a rubber strip needs to keep its shape, resist edge deformation, and perform under repeated pressure or contact. For gasket, edging, spacer, and wear strip work, thickness alone is not enough for material selection. Hardness grade, tensile strength, elongation, compression set, surface finish, and slit width tolerance all affect how the strip behaves after cutting and installation.
For softer contact areas, 40-50 Shore A grades are easier to bend and fit. A 60 Shore A grade is often chosen for neoprene gasket strip and general mechanical protection because it offers a practical balance between flexibility and cutting stability. When the part needs stronger resistance to squeezing, abrasion, or edge collapse, 70-80 Shore A grades are usually more suitable.
Mechanical performance is also important during conversion. Typical tensile strength is around 8-12 MPa depending on grade, while elongation is commonly around 200%-400%. These values help the material resist tearing during slitting, die cutting, handling, and fitting. For narrow cut neoprene rubber strip, we recommend checking thickness tolerance, width accuracy, edge smoothness, curl after cutting, and 24-72h dimensional stability before larger production runs.
Benefits
- Hardness choice for real use: 40-50 Shore A supports easier fitting, 60 Shore A suits balanced gasket work, and 70-80 Shore A improves wear and deformation resistance.
- Dense solid rubber body: The strip is non-foam and non-porous, making it suitable for gasket cutting, edging, spacers, and mechanical contact parts.
- Better cutting durability: Typical 8-12 MPa tensile strength and 200%-400% elongation help reduce tearing during slitting, die cutting, and assembly.
- Controlled pressure recovery: Compression set around 25%-35%, depending on compound and test condition, helps evaluate long-term performance under load.
- More reliable strip dimensions: Thickness tolerance can typically be controlled around +/-0.2 mm to +/-0.5 mm, with slit width tolerance around +/-0.5 mm to +/-1.0 mm.
- Plain or adhesive-backed supply:Plain strips suit mechanical fixing, while PSA-backed strips help positioning during assembly and require liner release, bonding, and edge cleanliness checks.
What should be checked before cutting solid neoprene rubber strip into gaskets or edging parts?
Before cutting Solid Neoprene Rubber Strip into gaskets, edging parts, spacers, or wear pads, check hardness, thickness tolerance, strip width accuracy, and edge quality after slitting. A 60 Shore A dense neoprene rubber strip is often practical for general gasket work because it keeps a useful balance between flexibility and mechanical strength. For harder grades, sample strips should be checked for edge tearing, curling, and deformation after cutting. For adhesive-backed parts, liner release, adhesive hold, and edge cleanliness should be tested after 24-72 hours before bulk production.

How does Shore A hardness affect mechanical performance in solid neoprene rubber strip?
Shore A hardness changes how a solid neoprene strip behaves under pressure, stretching, friction, and repeated assembly. Softer grades conform more easily to uneven surfaces, but they may deform more under load. Medium hardness grades provide a practical balance of tensile strength, elongation, abrasion resistance, and cutting stability. Harder grades are better when the strip must resist squeezing, edge collapse, or mechanical wear. Hardness should be checked together with compression set, thickness tolerance, oil exposure, outdoor aging, and final fixing method.
FAQ
Q1: What hardness is most common for Solid Neoprene Rubber Strip?
60 Shore A is a common general-purpose grade because it balances flexibility, strength, and cutting stability.
Q2: Can the strip be supplied with adhesive backing?
Yes. It can be supplied plain or PSA-backed with a release liner for easier positioning during assembly.
Q3: Is this strip suitable for gasket cutting?
Yes. It is suitable for gasket strips, edging parts, spacers, pads, and die-cut rubber components.
Q4: What should be tested before bulk use?
Check hardness, thickness tolerance, compression behavior, edge quality, bonding performance, and 24-72h dimensional stability.
