Aliphatic Polyketones in Pipe Applications

 

Materials & Resins # 1998 Gothenburg

Aliphatic polyketones are a family of polymers prepared by the polymerisation of olefins and carbon monoxide in a perfectly alternating sequence. BP Chemicals produces these materials using a proprietary palladium catalyst in a continuous polymerisation process.

They are crystalline thermoplastics which offer a unique combination of mechanical, high temperature, chemical resistance, wear and barrier properties. The resistance to permeation of polyketones specifically to oxygen, hydrocarbons and other reagents is comparable to that of ethylene vinyl alcohol copolymers (EVOH). This performance creates the potential for use in pipe applications for industrial chemicals, solvents, fuel and automotive products.

Author(s) : Lowe, Starkey, Powell

With the increasing success of PE100 and usage of pipes of increasingly large diameter, concerns have been raised about the quality of weld performance with relatively thick walled pipes (>50mm), which has led to the current investigation. In addition to the consideration of welding conditions adopted in the UK,...

The process of die-drawing has been investigated as a means of producing oriented polyethylene pipe. Two materials, one homopolymer and one copolymer, have been successfully drawn into pipe. When compared with isotropic pipes the oriented products exhibit enhanced mechanical and physical properties and produce a novel...

Long term failure of plastics pipes is governed by very slow crack propagation. Assessing pipe materials' resistance to this slow growth is time consuming and in the case of recent very tough medium density polyethylenes is difficult using constant load tests. It is shown that fatigue tests can achieve comparative...
