摘要:
Films comprising a resin matrix, an entanglement polymer, and a latent curative, wherein the resin has a functionality of at least 2.0 and a viscosity of at least 0.1 Pascal-seconds, and the film is dimensionally stable at 25° C. The films are particularly useful for the bonding of elastomers to rigid substrates, such as rubber to metal, and contain no volatile organic compounds (VOCs), and are shelf stable for extended periods of time.

To provide an element including: a first electrode; an intermediate layer; and a second electrode, the first electrode, the intermediate layer, and the second electrode being disposed in this order, the intermediate layer including an organic polymer material, where a molecular structure of the organic polymer material includes a structure represented by the following formula (1) where R1 is a carbonyl group, an ether group, a thioether group, or organopolysiloxane, and R1 may form a cyclic structure (an imide group) with R2; and R2 to R6 are organic groups that may be identical or different, where each of the organic groups may have a valency of 2 or more and may form another structure:
摘要:
Compositions having a compound comprising at least one alkoxy silane moiety, and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor and combinations thereof; and an aqueous or water containing carrier medium are provided for use in polymer bonding. The water may allow for substantial hydrolysis of the compound. Suitable polymers may have diene or allylic functionality within the polymer chain, for example an elastomer such as a natural or synthetic rubber. The polymers may be bonded to metals or substrates with hydroxylated surfaces such as glass. The nitrosobenzene precursor may be at least one of a quinone dioxime or a quinone oxime.
摘要:
The invention relates to a chassis component comprising at least one first component part consisting of a composite material that damps structure-borne sound and consists of one first metal layer, at least one second metal layer, and at least one damping layer arranged partially or across the whole surface between said metal layers. The invention also relates to two corresponding methods for the production of same, and to a corresponding use.
摘要:
The invention relates to a flexible tubular pipe (10) for transporting, in an off-shore environment, suspensions of loose mining aggregates, said flexible tubular pipe (10) having on the inside a layer of polymer material (12) defining a free internal surface (24), said layer of polymer material (12) having protective elements (30) embedded in the thickness of said layer of polymer material (12) so as to be able to be flush with said free internal surface (24) in order to preserve said layer of polymer material (12) when suspensions of loose mining aggregates flow inside said flexible tubular pipe (10). Said protective elements comprise particles of a solid lubricant (30).
摘要:
A composition includes: a polythiol compound; a (meth)acrylic compound having a plurality of at least one of an acryloyl group or a methacryloyl group and having a ring structure; and a radical generator, the ratio (Ac/SH) of the total molar number (Ac) of the at least one of an acryloyl group or a methacryloyl group contained in the (meth)acrylic compound to the total molar number (SH) of thiol groups contained in the polythiol compound is higher than 0.20 but lower than 0.70.
