The invention relates to a thermoplastic elastomer composition comprising a thermoplastic elastomer and a flame retardant, wherein the flame retardant comprises at least a compound selected from the group consisting of piperazine phosphate, piperazine pyrophosphate and piperazine polyphosphate, and a phosphoric acid compound.

Flame retardant thermoplastic elastomers

Thermoplastic vulcanisate containing 5-70 parts by weight semi-crystalline polyolefine, 95-30 parts by weight rubber containing an at least partly vulcanised polymer, which polymer contains ethylene monomeric units, monomeric units derived from an alpha-olefine and monomeric unit derived from a non-conjugated polyene, and oil whereby the sum of the concentration of aromatic compounds and the concentration of polar compounds in the oil being less than 4.5 wt. %.

Thermoplastic vulcanisate, the thermoplastic vulcanisate containing a foaming agent and foam of the thermoplastic vulcanisate

The invention relates to a process for the preparation of a thermoplastic elastomer comprising preparing a blend of a rubber and a thermoplastic resin, in which the rubber is at least partially vulcanized by using a phenolic curative. The invention is that, to overcome problems with surface quality, an effective amount of a Lewis base is added after the desired degree of vulcanization of the rubber is obtained. The invention also relates to a process for the preparation of an UV-stable thermoplastic elastomer.

Process for the preparation of a thermoplastic elastomer

The invention relates to a thermoplastic elastomer comprising a blend of a rubber and a thermoplastic resins the rubber being at least partially cured with a phenolic curative. The invention is that, to overcome problems with surface cracking, the thermoplastic elastomer also comprises a hydrolysis-insensitive HALS-compound. The invention also relates to the preparation of such a thermoplastic elastomer.
