A downhole tool, provided with: a downhole-tool member containing a reactive metal; a downhole-tool member containing a degradable resin composition that promotes degradation of the reactive metal, preferably a degradable resin composition containing a degradable resin that generates an acid by degradation or a degradable resin composition containing a degradable resin and an inorganic substance or organic substance that promotes degradation of the reactive metal; and, as desired, a degradable rubber member. Moreover, a well-drilling method using this downhole tool.

A fire resistant cable comprising: at least one conducting element; at least one layer, surrounding said conducting element, made of a ceramifiable composition comprising: a polymeric material comprising an ethylene/vinyl acetate copolymer as main polymer; at least 25 wt % of silica; a fluxing agent selected from alkaline metal oxides or precursors thereof; a stabilizing agent comprising at least one of MgO, CaO, PbO, B2O3, or a precursor thereof; from 0.1 wt % to 5 wt % of a hydroxide selected from magnesium hydroxide, aluminium hydroxide and mixtures thereof; the above percentages being expressed with respect to the weight of the ceramifiable composition. Upon exposure to elevated temperatures such as those encountered in case of fire, the ceramifiable composition is transformed into a ceramic material capable of protecting the conducting element from fire and mechanical stresses. The fire resistant cable of the present invention can continue operating under fire conditions for a certain period of time.

A composite material for producing an extrudate may include: PVC and granules of cereal chaff. The granules of cereal chaff may include spelt, hulls, granules, seed coats and/or stem parts. The cereal may be Pooideae and/or Panicoideae and/or Andropogonoide-ae.

The present disclosure relates to a thermoplastic polyurethane (TPU) based polymer electrolyte composition hosting an ion conductive salt in the presence of a plasticizer.

Corrosion resistance coatings and dicyclopentadiene modified ester oligomers useful in corrosion resistant coatings. The corrosion resistant coatings exhibit improved corrosion resistance, improved adhesion, lower toxicity, unlimited pot life, and/or lower volatile organic compounds (VOCs).

An acrylic rubber bale excellent in storage stability and water resistance and a method for producing the same are provided. An acrylic rubber bale, including an acrylic rubber having a reactive group, with a specific ash content, a large proportion of magnesium and phosphorus in the ash, and a specific ratio of magnesium and phosphorus, is highly excellent in storage stability and water resistance. This acrylic rubber bale can be produced by using a specific stabilizer and a specific coagulant in an emulsion polymerization process of an acrylic rubber and performing a process from coagulation process to baling process under specific conditions.
