Handbook of polymeric foams and foam technology

Describing all classes of polymeric foams, including their chemistry, synthesis, commercial production methods, properties, and applications, this handbook is designed to support engineers in their effort to develop practical solutions for industrial design and manufacturing challenges.  

Design of experiments: a no-name approach

Presents a novel approach to the statistical design of experiments, offering a simple way to specify and evaluate all possible designs without restrictions to classes of named designs. The work also presents a scientific design method from the recognition stage to implementation and summarization.

Adhesive Terminology – Z

Z (Impedance) – Variable for Electrical Impedance (The opposition a circuit offers to the flow of alternating current) expressed in ohms

Adhesive Terminology – Y

Yield – The percent of usable, defect-free lumber that can be cut from a rough cutting, board, or bundle of lumber. Yield value – The stress (either normal or shear) at which a marked increase in deformation occurs without an increase in load.

Adhesive Terminology – X

X (Reactance) – Variable for Electrical Reactance (Opposition to the flow of alternating current).

Adhesive Terminology – W

Warp – A significant variation from the original, true, or plane surface. Watt – A unit of electric power. The product of a volt times an ampere. Webbing – Filaments or threads that may form when adhesive transfer surfaces are separated. Wood failure – The rupturing of wood fibers in strength tests on bonded specimens, [...]

Adhesive Terminology – V

V-joint – A glue joint in which one side is thicker than the other as a result of poor machining or uneven application of pressure. Vacuum Press – A press designed for laminating or veneering in which the panel is placed inside of a flexible bag connected to a vacuum pump. Vapor Density – The [...]

Adhesive Terminology – U

Ultimate elongation – Elongation at failure. Ultraviolet light – Part of the light spectrum. Ultraviolet rays can cause chemical changes in rubbery materials. Urethane – A family of polymers ranging from rubbery to brittle. Usually formed by the reaction of a di-isocynate with a hydroxyl. UV – Ultraviolet Light.
