He added their study provides the first information on the presence of acetals
in e-cigarette aerosol.
Examples are a cyclic acetal
named Vulkazon AFS and an enol ether named Vulkazon AFD.
For the reaction process studied here C[O.sub.2] may also act as a compatibilizing agent, allowing for various aldehydes and mixtures of aldehydes to be used in the production of novel poly(vinyl acetals
One more thing of interest that applies equally to both families is the inability with today's technology to impart flame-retardant properties to acetals
. The traditional route of using halogenated FR systems is not an option with acetals
because of the violent reaction that these polymers undergo with any chlorinated or brominated substances.
Custom-matched dry colorants and color concentrates for PE, PP, PS, ABS, PC, acrylic, SAN, nylon, acetal
, NAS, BDS.
Delrin 100TL acetal
with Teflon PTFE micropowder combines high impact strength and elongation with low wear and friction.
At the top of DuPont's news in acetals
is Delrin 560HD, which resists hot diesel fuel much better than standard acetals
slate now includes an ultra-low-friction, lubricated Tenac grade for telecommunication equipment and a conductive version for fuel-pump modules.
DuPont, for example, has overcome some deficits of acetals
with new Deirin grades that have better melt strength for large-part thermoforming and greater adhesion to paint or other resins.
Used in nylon, acetal
, phenolics, PTFE, epoxy and other resins at loadings of 2% to 40%.
In his 40-plus years of experience with rotational molding, Beall has encouraged attempts to rotomold nylon, acetal
, polycarbonate (PC), and other engineering resins.
, more commonly known these days as POM, presents a different problem.
