MULTILAYER PRESSURE-SENSITIVE ADHESIVE FOAM TAPE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18289537 titled 'MULTILAYER PRESSURE-SENSITIVE ADHESIVE FOAM TAPE

The patent application describes a multilayer pressure-sensitive adhesive foam tape with unique properties.

• The foam tape consists of a polymeric foam layer with pressure-sensitive adhesive properties.
• The polymeric foam is derived from a poly(meth)acrylate with a weight-average molecular weight no greater than 500,000 g/mol.
• The foam tape includes optional additives such as solid fillers, tackifiers, VOC scavengers, and stabilizers.
• It has a first pressure-sensitive adhesive skin layer on one major surface and a second pressure-sensitive adhesive skin layer on the other major surface.

Potential Applications: - Bonding materials in various industries such as automotive, construction, and electronics. - Sealing gaps and joints to prevent leaks and drafts. - Mounting objects on surfaces securely and easily.

Frequently Updated Research: Stay updated on advancements in polymeric foam materials, pressure-sensitive adhesives, and adhesive tape manufacturing processes to enhance the performance and applications of this innovative foam tape.

Questions about Pressure-Sensitive Adhesive Foam Tape: 1. How does the weight-average molecular weight of the poly(meth)acrylate affect the properties of the foam tape? The weight-average molecular weight influences the flexibility, adhesion strength, and durability of the foam tape. Lower molecular weights may result in softer foams with better conformability, while higher molecular weights can provide higher strength and resistance to deformation.

2. What are the key factors to consider when selecting additives for enhancing the performance of pressure-sensitive adhesive foam tapes? The selection of additives depends on the desired properties of the foam tape, such as adhesion strength, flexibility, and resistance to environmental factors. Factors like compatibility with the polymer, cost-effectiveness, and regulatory compliance also play a crucial role in choosing the right additives for the foam tape.

Original Abstract Submitted

A multilayer pressure-sensitive adhesive foam tape that includes: a pressure-sensitive adhesive polymeric foam layer having a first major surface and a second major surface, wherein the polymeric foam comprises: a poly(meth)acrylate derived from a (meth)acrylate-based (co)polymer component having a weight-average molecular weight (Mw) no greater than 500,000 g/mol and comprising at least one reactive functional group (X); and an optional additive selected from the group consisting of a density-reducing solid filler, a tackifier, a VOC scavenger, an odor absorber (particularly, activated carbon), a stabilizer, a rheological modifier, a thixotropic compound, and a combination thereof; a first pressure-sensitive adhesive skin layer adjacent the first major surface of the foam layer; and a second pressure-sensitive adhesive skin layer adjacent the second major surface of the foam layer.
