The present invention comprises a method for producing a tube preform using an injection moulding method. The inventor of the present invention has found that in the case of using an injection moulding method to produce tube preforms which can be constructed with either one layer or a plurality of layers, and of subsequent extension, in particular by heating the preform, and biaxial expansion by means of compressed air, a tube can be obtained which, on the one hand, has a tube shoulder with the strength required by industrial thread and, on the other hand, has a lateral surface which exhibits the softness desired for a tube.

The anti-icing composition according to claim 9, wherein one of the materials capable of microphase separation and graftable into the glassy matrix is vinyl terminated polydimethylsiloxane polymer reacted with dimethylethoxy silane or 1,1,3,3 tetramethyl disiloxane and triethyl silane using a hydrosilylation reaction. 13. The anti-icing composition according to claim 9, wherein the freezing point depression agent is a polyol, salt or choline or mixture thereof. 14. The anti-icing composition according to claim 13, wherein the freezing point depression agent is a mixture of glycerol and magnesium chloride hexahydrate. 15. The anti-icing composition according to claim 9, wherein the glassy matrix is crosslinked using an organotitanate or tin catalyst agent. 16. A substrate coated with the anti-icing composition according to claim 9. 17. An anti-icing composition, comprising: a) a glassy matrix formed by crosslinking a mixture of an epoxy, an alkoxy-functionalized siloxane, and a compound capable of compatibilizing the epoxy and the alkoxy-functionalized siloxane to provide an epoxy-modified interpenetrating polymer network of glass and epoxy; b) at least two materials capable of microphase separation, at least one of which is graftable to the glassy matrix; and c) a freezing point depression agent. 18. The anti-icing composition according to claim 17, wherein the alkoxy-functionalized siloxane is selected from the group consisting of polydiethoxysiloxane, polydimethoxysiloxane, tetramethoxy silane and tetraethoxy silane. 19. The anti-icing composition according to claim 17, wherein one of the materials capable of microphase separation and graftable into the glassy matrix is vinyl-terminated polydimethylsiloxane polymer reacted with dimethylethoxy silane and triethyl silane using a hydrosilylation reaction. 20. The anti-icing composition according to claim 17, wherein the freezing point depression agent is a polyol or a salt hydrate or mixture thereof. 21. The anti-icing composition according to claim 20, wherein the freezing point depression agent is a mixture of glycerol and magnesium chloride hexahydrate. 22. The anti-icing composition according to claim 17, wherein the epoxy is selected from the group consisting of a polyglycidyl ether of a polyhydric polyol, polybisphenol A-epichlorohydrin glycidyl end-capped and polybisphenol F-epichlorodydrin glycidyl end-capped. 23. The anti-icing composition according to claim 17, wherein the compound
