PQD Para Quinone Dioxime
Para Quinone Dioxime (PQD)
What is PQD?
PQD is a non-sulphur vulcanizing agent for synthetic elastomers. It is used extensively for rapid curing of butyl stocks requiring heat resistance. Butyl of this type is used to fabricate high voltage wire and cable products, moulded electric components, and heat resistant seals and hose. PQD has also been used as part of the curative system for liquid butyl elastomers. These compounds are formulated as coatings, sealants and electrical encapsulants. The proper choice of PQD and a co-curative, such as lead dioxide or tertiary-butyl perbenzoate, will effect room temperature curing. PQD also functions as a curative for Ethylene Propylene Terpolymers (EPDM). Improved heat aging properties are of particular significance with EPDM elastomers.

    Kevlar is a fiber which Howard W. Swank, general manager of Du Pont’s Textile Fibers Department, and other Textile Fibers Department’s managers were keen on. Kevlar is based on the former products of Du Pont, such as nylon, and Nomex Aramid fiber. Kevlar’s development was closely related to that of Nomex. It is a much stronger and stiff fiber than nylon and steel, and can be stable at high temperatures. After the Fiber-B first came out in 1960s, Du Pont found some problems with it. Two years later, Fiber B-1, which is also called Kevlar Aramid fiber, came out with better properties. The Textile Fibers Department thought Kevlar could meet the potential needs of both existing and potential customers. Actually, Du Pont needed new products like Kevlar, because its major products’ earnings were softening under increased competition.…
