The term “acoustically clear” means that acoustic energy is able to enter and transit through the material with a minimal amount of reflection, loss, distortion or absorption only a small

Electrical and electronic encapsulants – Acoustic Polymers

Acoustic Polymers Ltd offers a wide range of thermosetting epoxy, polyurethane and silicone encapsulation and moulding compounds for a diverse range of applications. Encapsulation is a general term meaning to surround with insulation. The word is often used interchangeably with potting, casting or sometimes over-moulding. The general properties of our Read More Introduction to Laminated Glass Interlayersacoustic performance. For cost effective manufacture of a laminated glass incorporating PVB interlayers, in most situations an ‘autoclave’ must be used which applies both heat and pressure as part of a controlled cycle.

Organophosphorus flame retardants and plasticizers: Sources

1/1/2015 · With the gradual discontinuation of the use of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) as flame retardants (FRs) due to their confirmed persistence, long-range atmospheric transport (LRAT), bioaccumulation and/or toxicity (U.S. Environmental Protection Agency, 2009), an urgent demand for alternative FRs has been increasing. DAMPING PROPERTIES OF MATERIALS – Vibrationdatadamping, such as viscous, hysteresis, acoustic coupling, air pumping at joints, energy radiation to the soil, etc. Also, boundaries and bearings contribute damping. Furthermore, structures have many modes. Each mode may have a unique damping value.
