摘要：Described is the use of a tube of plastics on the basis of a vinylchloride polymerwhereby the tube has been given a ductile fracture behaviour in the test for establishingthe fracture toughness thereof. The ductile fracture behaviour is provided by theaddition to the plastic of 0,3-4 wt.% of an agent which influences the fracture behaviourwhich may be chosen from agents which are known per se and which improve the notchedimpact toughness. Also is described a pressure pipe from such plastic and a tube for usein such a pressure pipe.
