Each section consists of a reaction plate where the reaction mixture flows, surrounded by two cooling plates containing the UE. The reactants and catalyst are stored separately and put into contact at the opening of the first reaction plate. The pilot holdup is typically 1.5 1. The successive plates of the reactor can be represented as shown in Figure 12.1. Inside the reactive plate (RP), the environment of the reaction mixture is composed of PEEK. The UE flows between two stainless steel plates, the sandwich plate (SP) and the transition plate (TP).

Imperial Chemical Industries has introduced a new crystalline poly(ether ether ketone) (PEEK) (structure 4.78). Applications are for compressor plates, valve seats, thrust washers, bearing cages, and pump impellers. In the aerospace industry it is employed as aircraft fairing, fuel valves, and ducting. It is also used in the electrical industry as wire coating and semiconductor wafer carriers. 

The steel plates are made by milling and the PEEK tubes by turning and milling [39]. 

Figure 11-14. Eight-channel parallel LC-MS system consisting of Shimadzn gradient HPLC pumps, a Gilson 215 multiple probe autosampler, an AB/MDS-SCIEX API165 mass spectrometer equipped with a TurboIonSpray ion sonrce, eight Peeke Scientific microbore columns (10-mm x 1-mm-i.d., 3-pm HQ-C18), and a Valeo switching valve. The volume of the sample loops is 20 pL, and full loop injections were used for all experiments. Total mobile-phase flow rate is 2.0mL/min (0.25mL/min for each column). The eight-channel LC-MS system allows up to four plates of compounds (or 4 X 1152 samples) to be run in a single day.

PEEK-WC is a modified PEEK, as shown in Figure 6.2. Ultra-thin asymmetric gas separation membranes of modified PEEK can be prepared by a dry/wet phase inversion technique [61,62]. Under optimized conditions, membranes with an open cellular morphology and an ultra-thin dense skin of about 50 nm can be obtained. The membranes are prepared by casting a film of a solution of PEEK-WC on a glass plate. The films are then coagulated, dried, and removed from the glass plate. 

Icotec have developed a range of composite floating anchor nuts, which snap into a base plate mounted on a structure. One version is based on a carbon fiber/PEEK construction, providing low weight and is able to match the coefficient of expansion of the surrounding PEEK composite material.
