The wall is made of a polymer, which by weight is from 40 to 90% C1-C24-alkyl ester of acrylic acid, methacrylic acid, or both (“first monomer”); from 10 to 60% an ethylenically unsaturated crosslinker; and from 0 to 30% an ethylenically monounsaturated monomer different from the first monomer. At least 80% of the crosslinker is has three or more ethylenically unsaturated radicals. The core is made of a paraffin composition, which by weight has from 35 to 98% n-octadecane; from 1 to 10% C20-C24-aliphatic, diisopropylnaphthalene, or both; from 1 to 5% wax with a melting point >40° C.; and from 0 to 50% n-hexadecane.
