Key statement: A tire having an internal surface includes an electronic device and an anchoring body mounted on the internal surface for engagement between the electronic device and the internal surface of the tire, wherein the anchoring body includes a cross-linked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition including a synthetic diene rubber, preferably in an amount of from 20 to 80 phr, and a halogenated butyl rubber, preferably in an amount of from 80 to 20 phr.
The materials' promise lies in their vast internal surface area.
These properties, in areas such as Wallasey, New Brighton, Leasowe and Heswall, had all suffered internal surface water flooding during an extreme storm a year ago and met the criteria to qualify for funding from the Environment Agency to pay for measures to prevent, or at least minimise the damage caused by, any future flooding.
In addition, plastic or stainless options are available for both manual and actuated valves, standard internal surface finishes are available--corresponding to BPE-SFV3 (30 Ra max), SFV4 (15 Ra max electropolish) and SFV6 (25 Ra max electropolish)--and the common body size for all the mini valve sizes allows interchangeability of bonnet, actuator and diaphragms.
Developed for and tested by the semiconductor industry, the Pura provides minimum flow path, reduced internal surface area, and contains no unnecessary sampling volume.
The researchers' new creation, which is featured in the current issue of the journal Nature, comprises a lattice structure of alternating zinc oxide molecules and 1,3,5-benetribenzoate, and has a "record" internal surface area equivalent to 17 tennis courts per gram of material.
