PVC foam tapes offer a versatile and cost-effective solution for sealing, gasketing, cushioning, and vibration dampening. Engineered from durable closed-cell PVC foam, these tapes provide excellent resistance to water, dirt, air infiltration, UV, oxidation, and fungi. Ideal for demanding applications in construction, automotive, electronics, HVAC, and industrial assemblies, our PVC foam tapes are available with high-performance pressure-sensitive adhesives and can be customized to your precise specifications.
Superior Sealing Properties: Closed-cell structure creates an excellent barrier against water, air, dust, and light.
Excellent UV & Weather Resistance: Maintains integrity and performance in outdoor and harsh environments.
Conformability & Flexibility: Adapts to irregular surfaces, ensuring a consistent seal. Available in various softness grades.
Good Cushioning & Vibration Dampening: Absorbs shock and reduces noise for improved product performance and user comfort.
Chemical & Oil Resistance: Suitable for applications exposed to various chemicals and oils.
Range of Compression Force Deflection (CFD): Offered in various CFD ratings to match compression requirements.
Choice of Adhesives:High-performance acrylic or rubber-based PSAs for strong, durable bonds to various substrates.
1.Compounding
The selected PVC material is expertly mixed with precisely chosen additives such as blowing agents, fillers, and stabilizers. This critical compounding phase at GMARK is essential for achieving the desired foam characteristics, including specific density, resilience, and performance attributes. For our closed-cell PVC foam tape, specific blowing agents are meticulously integrated to create a consistent and uniform closed-cell structure, key to its sealing and insulation properties.
2.Foam Formation
The compounded PVC mixture then undergoes a carefully controlled foaming process. Heat and blowing agents work in synergy to expand the material, meticulously creating the closed-cell foam structure. This process results in a lightweight, flexible foam with excellent insulation, cushioning, and impact absorption properties, ready for diverse applications.
3.Adhesive Application
For applications requiring self-adhesive tape, a high-quality, performance-matched pressure-sensitive adhesive is expertly applied to one or both sides of the PVC foam, as per specification. The adhesive system is carefully selected for its strong bonding capabilities while maintaining the integrity and performance of the foam. This precise adhesive application ensures the PVC foam tape adheres securely and reliably to various substrates and end-use conditions.
4.Shaping and Cutting
The foamed PVC material is initially shaped into master sheets or rolls. It is then precisely converted to meet exact customer dimensions, whether as continuous rolls, sheets, or custom-sized parts. At CMARK, the foam can also be accurately slit into narrower strips or die-cut into specific, intricate shapes to meet diverse application needs and tight tolerances.
5.Quality Control & Packaging
Throughout the manufacturing process, and particularly before final dispatch, rigorous quality control checks are performed to ensure all specifications are met. Finished PVC foam tape products are then carefully packaged to ensure they arrive in perfect condition, ready for your application.
For General Service Providers and Building And Construction Firms, a reputation is built one task each time. The integrity of your curtain walls, the accuracy of your glass installations, and the long-term efficiency of the structure envelope are non-negotiable. Worldwide of modern-day style, where glass plays a main structural and visual duty, the components you pick are just as crucial as the layouts you carry out.
We give a total series of top architectural glazing spacer tapes, the critical element for first-rate structural silicone glazing systems. For over 15years, our fundamental technology has been the industry standard, trusted on spots tasks across the globe. These tapes are engineered not simply to carry out a function, however to guarantee the long life, security, and flawless look of your most demanding polishing applications.
What is an Architectural Glazing Spacer Tape?
At its core, our polyurethane foam tape offers an essential dual purpose in structural glazing systems. First, it serves as a precision spacer, producing a constant, uniform void between the glazing panel and the structure’s structure. This regulated room is crucial for applying the appropriate quantity and depth of structural silicone sealant– the adhesive that ultimately bears the lots and protects the glass. Second, it offers a momentary but powerful bond, holding glass lites firmly in position throughout assembly and sealer curing, enhancing both field and store fabrication.
Superior Load Resistance: Our tapes are rigorously evaluated to outshine rivals in load deformation. They resist compression collection, implying they will not squash or flatten under the immense and continual weight of heavy glass systems, ensuring the defined void is maintained for the life of the framework.
We utilize a pressure-sensitive acrylic adhesive. It's created for outstanding tack and shear toughness, providing a trustworthy short-term hold throughout the essential assembly phase. It is engineered for compatibility with major architectural silicone sealer brands, eliminating the risk of adverse chemical reactions.
Examined against severe weather condition, UV exposure, and moisture, our spacer tapes preserve their structural residential properties over decades. Their reduced dampness vapor transmission price (MVTR) secures the honesty of the entire glazed system.
GMARK PVC foam tapes deliver robust sealing, thermal/sound insulation, and excellent adhesion. Our closed-cell structure and high-quality acrylic adhesives ensure long-lasting performance on diverse surfaces. Engineered for industrial demands, we offer extensive customization in density, thickness, adhesive, and converting to meet your precise application needs.
