Solvent cement formulations
11674060 · 2023-06-13 · ·

Provided are solvent cement formulations comprising some or all of tetrahydrofuran, cyclohexanone, methyl ethyl ketone, acetone, a thermoplastic resin, silica, and, a solvent soluble acrylic copolymer associative thickener. The disclosed formulations contain a reduced complement of volatile organic compounds (VOCs) relative to conventional cement formulations, yet are capable of meeting the requirements for regular-, medium-, and heavy-duty applications. The use of specialized associative thickener components confers a required degree of viscosity while enabling a reduction in the concentration of VOCs, such as tetrahydrofuran.

Pipe joining material for connecting pipes

A pipe joining material for connecting pipes and fittings and a method of making a pipe joining material are provided. The pipe joining material may include a thermoplastic material such as polyvinyl chloride (PVC) and/or chlorinated polyvinyl chloride (CPVC) and a bonding agent for the thermoplastic material.

Machinable enveloping of adhesive tape with a backing layer
11370943 · 2022-06-28 · ·

An adhesive tape with a backing layer is longitudinally folded upon itself, creating an approximately 180-degree angle at each of two ends of the tape, and a first longitudinal section of multiple layers of the adhesive tape and a second longitudinal section of multiple layers of the adhesive tape such that the first section is positioned above and parallel to the second section. The folding does not crease the tape at either end of the tape. The first longitudinal section and second longitudinal section are maintained in contact or close proximity via a piece of tape, clip, rubber band, or other means, such that the adhesive tape is maintained in a flat profile. The adhesive tape in its flat profile can then be easily inserted into a United States first class letter-sized mailing envelope.
