摘要:
A polybutylene based hot melt adhesive composition having a variety of end uses, particularly in construction and elastic attachment applications for nonwoven articles such as disposable diapers. Unlike typical hot melt adhesives, the present composition can withstand high peel and shear loads at elevated temperatures for extended periods of time without experiencing catastrophic bond failure. The composition includes polybutylene polymer or a mixture of polybutylene and polyolefin polymers, and a stabilizer, with the remaining ingredients chosen from one or more of a polyolefin polymer, a tackifier resin, a plasticizer, or a wax. The hot melt adhesive composition can be applied using common application techniques such as extruding or spraying.
摘要:
This invention discloses a thermally expandable composition for use in actuators having a high thermal conductivity. This composition contains about 10-50 weight percent graphite particles dispersed in a wax or polymer. The high thermal conductivity of the composition increases the operating speed of the thermally-operated actuator.
摘要:
A composition and method are described for repairing surface defects in plastic objects, particularly laser-readable discs such as audio compact discs, video laser discs and computer memory discs. Using the composition and method, a surface defect in the disc is smoothed over and filled with a waxy material having a refractive index approximating that of the plastic substrate, thereby forming a repair which does not distract the laser and permits continued use of the disc.
