High Density PVC Foam Tape 2mm with Double-Sided Acrylic Adhesive

 

Product Introduction

 

High Density PVC Foam Tape is manufactured from closed-cell PVC foam with a typical density of 350±50 kg/m³. Both sides of the foam backing are coated with high-strength acrylic pressure-sensitive adhesive and protected by a release film.

 

The relatively high-density foam structure gives High Density PVC Foam Tape greater body and dimensional support than softer low-density foam materials. The 2mm thickness provides a defined bonding layer while allowing the foam to accommodate minor surface irregularities.

 

High Density PVC Foam Tape is designed for applications where controlled joint thickness, sealing, cushioning and reliable adhesion are required in the same construction. The closed-cell PVC structure helps resist moisture penetration and provides useful environmental sealing performance.

 

The smooth surfaces of High Density PVC Foam Tape provide consistent contact with the adhesive layers. The foam construction can be supplied in different densities and thicknesses according to the required compression, recovery and joint design.

 

Product Construction

 

High Density PVC Foam Tape consists of three main functional layers: a high-density closed-cell PVC foam core, acrylic pressure-sensitive adhesive on both sides, and a protective release film.

The PVC foam core provides the physical body of the tape. The double-sided acrylic adhesive creates the bonding interfaces, while the release film keeps the adhesive protected before installation.

The high-density foam construction is particularly useful when the finished joint needs a stable thickness. Compared with softer foam materials, a higher-density PVC foam can provide greater resistance to compression under the same loading conditions.

The exact performance of High Density PVC Foam Tape depends on foam density, thickness, adhesive formulation, compression level and substrate characteristics. The final specification should therefore be selected according to the actual application.

Closed-Cell Foam Structure

 

The closed-cell structure is an important feature of High Density PVC Foam Tape. Individual cells within the PVC foam create a relatively continuous barrier that helps reduce the passage of moisture and air through the foam body.

The closed-cell construction also gives High Density PVC Foam Tape useful resistance to environmental exposure. When compressed between two surfaces, the foam can conform to minor irregularities and contribute to the overall sealing function.

 

The 350±50 kg/m³ density provides a balance between foam flexibility and structural support. Higher-density PVC foam is suitable when the tape needs to maintain a more defined joint profile rather than simply acting as a soft cushioning layer.

 

 

Double-Sided Acrylic Adhesive

 

High Density PVC Foam Tape uses high-strength acrylic pressure-sensitive adhesive on both sides of the foam backing. The adhesive coating provides bonding interfaces for the two mating surfaces.

The acrylic adhesive provides good initial adhesion and peel performance on common substrates including glass, aluminum, stainless steel, metals and selected plastics.

 

High Density PVC Foam Tape can also be compatible with many chemical silicone sealants, making the construction suitable for certain glazing systems where foam tape and sealant are used together.

Actual compatibility depends on the specific sealant formulation and application conditions. Compatibility testing should be performed before large-scale installation.

 

 

Key Features

 

High-Density PVC Foam

The 350±50 kg/m³ foam structure provides greater body and compression resistance than lower-density foam constructions. High Density PVC Foam Tape can maintain a relatively stable joint profile under compression.

 

Closed-Cell Construction

The closed-cell PVC foam helps resist moisture penetration and supports sealing against water, dust and air when properly compressed between suitable surfaces.

 

Strong Acrylic Adhesive

Double-sided acrylic adhesive provides reliable contact with a variety of materials. High Density PVC Foam Tape can adhere to glass, aluminum, stainless steel, metals, plastics, wood and other commonly used substrates, subject to surface condition and adhesive compatibility.

 

Controlled Joint Thickness

The high-density foam structure helps maintain a defined bond-line thickness. This characteristic is useful when consistent spacing between two components is important.

 

Weather and UV Resistance

High Density PVC Foam Tape offers good weathering and UV resistance. The PVC foam and acrylic adhesive construction can be selected for applications exposed to changing environmental conditions.

 

Tear Resistance

The relatively strong internal foam structure provides good resistance to tearing during handling and installation. This helps maintain the integrity of the tape during application.

 

 

Product Advantages

 

One of the main advantages of High Density PVC Foam Tape is the combination of a relatively rigid foam structure and flexible surface conformity. The 350±50 kg/m³ density provides structural support while the closed-cell foam can still accommodate minor surface variations.

 

The double-sided acrylic adhesive creates a continuous bonding interface between the foam and the mating surfaces. This construction can simplify assembly while also providing a controlled foam layer between components.

High Density PVC Foam Tape can also provide an economical foam-based alternative for applications that would otherwise require thicker or more expensive sealing materials. Material selection should always be based on the actual mechanical, environmental and regulatory requirements of the project.

 

The ability to adjust density and thickness provides additional design flexibility. GMARK can supply lower-density, medium-density and higher-density PVC foam constructions according to the required compression and sealing characteristics.

 

 

Surface Adhesion

 

High Density PVC Foam Tape has good adhesion to several common materials, including glass, stainless steel, aluminum and other metals. The smooth adhesive-coated surfaces provide consistent contact when the substrate is properly prepared.

 

Before application, surfaces should be clean, dry and free from dust, oil, grease and loose particles. Surface preparation is especially important for glass and metal substrates where contamination can reduce effective adhesive contact.

 

Plastic, wood, silicone and other substrates can also be evaluated. Because surface energy, texture and chemical composition differ between materials, actual substrate testing is recommended before production use.

 

 

Compression and Sealing Performance

 

High Density PVC Foam Tape is designed to perform under compression rather than simply acting as a flat adhesive layer. When compressed between two surfaces, the foam can conform to small irregularities and help create a continuous sealing interface.

 

The specified construction has a compression strength of ≥75 kPa and a 30% compression set of ≤5% under the stated test conditions. These values provide reference information for evaluating the foam's resistance to compression and recovery.

 

The final sealing effect depends on compression percentage, joint geometry, substrate condition and environmental exposure. Application-specific testing should be completed when the tape is used as a primary weather or moisture seal.

 

 

Typical Applications

 

High Density PVC Foam Tape is suitable for selected glass systems where a defined foam joint and strong adhesion are required. The 2mm version can provide a controlled layer between mating components.

High Density PVC Foam Tape can also be used for commercial and residential window glazing, curtain wall components, glass structures and selected metal framing systems.

Other applications include commercial refrigeration equipment, HVAC duct systems, automotive and transportation components, and sealing structures made from metal, wood or vinyl profiles.

For applications involving silicone sealants, High Density PVC Foam Tape can be evaluated as a supporting sealing component. Compatibility between the acrylic adhesive, PVC foam and the selected silicone sealant should be verified before installation.

 

 

Available Density and Thickness

 

High Density PVC Foam Tape is available in a density range of approximately 300–500 kg/m³. The typical reference construction has a density of 350±50 kg/m³.

Available thicknesses range from approximately 0.5mm to 16mm, allowing the foam construction to be selected according to the required joint thickness and compression level.

GMARK can also provide different PVC foam density levels, including lower-density, medium-density and higher-density constructions. Density selection can influence hardness, compression behavior, recovery and sealing performance.

 

 

Color and Converting Options

High Density PVC Foam Tape is available in black, gray, white and brown. Special colors can be considered according to project requirements.

The tape can be supplied in standard rolls or converted into specific widths and shapes. Slitting, laminating and die-cutting can be evaluated according to the finished component design.

For high-volume applications, customized dimensions can help reduce material waste and simplify installation. Customers can provide drawings, dimensions or sample parts for converting evaluation.

 

 

Flame Retardant Options

High Density PVC Foam Tape can be supplied with selected flame-retardant grades. Depending on the specific formulation and construction, available standards can include UL94 HBF, HF-1 and V-0, as well as FMVSS 302 and BS476-7.

Flame-retardant performance is formulation-specific and should not be assumed for every PVC foam grade. The required flame-retardant standard should be confirmed before production so that the appropriate material construction can be selected.

 

 

Application Guide

Before installing High Density PVC Foam Tape, clean the bonding surfaces thoroughly and remove dust, oil, moisture and other contaminants.

Apply the tape to the first surface using consistent pressure. Avoid stretching the foam during installation because excessive stretching can change the final dimensions and compression behavior.

Remove the release film immediately before bonding the second surface. Position the mating component carefully and apply sufficient pressure across the bonded area.

For glazing, sealing or other applications with specific compression requirements, the joint design should be tested with the actual tape thickness and substrate combination before installation.
