A process for manufacturing pipes using thermoplastic pipe and “tape” (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds its fibers into pipe surface. The thermoplastic pipe is mechanically compressed prior fiber tape being applied. Outer diameter reduction of the pipe is at least partly maintained by the fiber tape being tightly wrapped around the pipe immediately after compression causes the pipe to contract. Then, an external heat source is applied to the pipe causing the thermoplastic to melt and the pipe to undergo thermal expansion. Fibers stretch less and are embedded into the molten layer of the pipe, creating a permanent bond between the fibers and the pipe. Individual pipes may be joined using couplers or butt welds.

The present disclosure provides an adhesive composition. The adhesive composition contains (A) multi-stage latex polymer particles, (B) a linear diamine base, and (C) an ethoxylated surfactant. The (A) multi-stage latex polymer particles include (i) a first-stage polymer containing acrylic acid monomer and a first vinyl monomer, and (ii) a second-stage polymer containing a meth acrylic acid monomer and a second vinyl monomer, with the proviso that the second vinyl monomer is different than the meth acrylic acid monomer. The first-stage polymer is bound to the second-stage polymer.

The anti-sticking layer prevents the hot melt tape from sticking the objects without needing a release film, and the hot melt tape can be directly heated during sealing the objects.

A hot melt adhesive uses a blend of polymers having controlled stereoerror and comprises a stereoblock polypropylene comprising a first block having an isotactic index of between about 50% and about 95% and a second block having an isotactic index of between about 5% and 50%, wherein the difference between the isotactic indeces of the first block and the second block is at least about 10%. The hot melt adhesive exhibits improved peel and tack properties without compromising shear strength and vice versa.
