Polyethylene Terphthalate - A family of plastics based on polymerization of an ester of diethylene glycol and terphthalic acid. 

Far-infrared spectrometers usually use a self-supporting film of polyethylene terphthalate, which has the trade name Mylar (or Melinex in Europe). The Mylar sheet has sufficient mechanical strength not... 

Vectra A is a commercially available polymer from Hoechst-Celanese. It is a random co-polyester of hydroxy benzoic acid (HBA) and hydroxy napthoic acid (HNA), which is a well-known class of thermotropic liquid crystalline polymer (TLCP) [92-95]. Crystallization of molecules of TLCPs is considerably different from that of polymers like polyethylene or polyethylene terphthalate [1], TLCPs have reduced flexibility compared to the latter, which implies that large translations of their molecules are required for recrystallization [96-99],...

Another inventionl l has described a method of producing a laminated composite for use as intravascular catheters such as angioplasty catheters (Fig. 10.48). In the first step, a parison was formed in a coextrusion of multilayer sheet through a die. The parison was heated in a mold and drawn to several times of original length. Next, the parison was expanded radially to the desired dimension and strength. The exterior of the expander was coated with hydrophilic material. Finally, the expander was bonded to the exterior of a tubular catheter. Fluoropolymers such as ETFE, ECTFE, PCTFE, PVDF, and PEA have been mentioned as intermediate layers that bond the outer layer (polyethylene terphthalate, PET), which were coextruded. 

Typical plastics used in electronic and electrical appliances are polyethylene, polypropylene or polyethene terphthalate, and these are studied here as part of the RoHS requirement for the presence of toxic metals. This method is to show that analysis of these plastics used in electrical and electronic equipment is essential, especially if the origin of the plastic is unknown and the supplier is unable to state whether or not they are free of these metals. The metals are measured against calibration standards curves for each metal and may also include additional attachments for improving limits of detection such as ultrasonic nebulisers for Cd, Pb and Cr and the cold trap method for Hg.

High-energy solids such as glass and poly(ethylene terphthalate) have high critical surface tensions (y. > 40 mN m ). Lower energy solids such as polyethylene have lower ( 31 mN m ). TTie same applies to hydrocarbon surfaces such as paraffin wax. Very low energy solids such as PTFE have lower y, of the order of... 

Dielectric measurements (relative dielectric constants, dielectric strength and dielectric loss factor) have been made for photodegraded polyethylene [1284], polystyrene [840, 2227, 2228, 2248] poly(ethylene terphthalate) [1040], polyamides and polyimides [120] and polycarbonates [1738].
