broadens the fi eld of applications of these materials,” said Antonio Esteban, technical specialist at Tolsa. “Our ultimate effort is increase the use of clay synergists in a wide range of systems that require the highest stand- ards of fl ame retardancy.” Tolsa’s technology allows modifi cation of the
sepiolite clay to meet the OEM’s strict requirements in terms of heat and smoke performance. In PVC applica- tions, for instance, the clay can be modifi ed to attain good dispersion and interaction with the polymer. “Each application is different so our ability to adapt and modify the product is an important advantage in meeting the FR requirements,” he said.

Victrex Peek helped Magma Global to develop its M-pipe technology, which can withstand pres- sures up to 103MPa
“The greater lubricity is a big advantage for inserting the seals into the fi ttings – a mechanical process in which lubrication increases speed and helps to prevent rejects,” said Stef Hordijk, general sales manager for the TPE division of Teknor Apex. “By reducing the forces needed for inserting the pipe into the fi tting, lubrication helps prevent improper assembly and damage to the seal.” The new lubricated compound exhibits greater
retention of sealing force over a period of years than rubber, prolonging the working lives of pipe seals. Seal- ing force is measured by the degree of stress relaxa- tion. Compared with rubber, both TPVs exhibit lower levels of stress relaxation over a period of years, particularly at higher temperatures.

Tolsa of Spain is to introduce a new range of high- performance fl ame retardant (FR) synergists. Its Adins Clay extended range are FR clay synergists that deliver reduced smoke production in PVC and rubber polymer systems, in addition to the existing FR additives used in other polymers. The additives can be used in a range of applications, including wire and cable, pipes and construction products. The new Adins grades use Tolsa’s technology, which is based on natural silicates. The company says that new materials help meet the new stringent demands for smoke performance (CPR and others) due to the use of more stable coatings than competitive clays. Other benefi ts include tailored performance

benefi ts, better processability and reduced cost in polymer systems. Tolsa says that the combination with halogen and
non-halogen FR and Adins additives in PVC and rubber systems reduces heat release and smoke generation in building and construction and structural applica- tions.

Victrex will exhibit its expanded portfolio in Peek, for industries ranging from aerospace to the automotive industry.
One application of direct relevance to pipe extruders is Magma Global’s M-pipe technology, which claims to reduce exploration and production costs and risks in subsea oil and gas systems as it is based on Victrex Peek pipe. The pipe can be deployed to depths of 10,000 ft (3,000m) and handle pressures of up to 15 ksi (103MPa). The composite pipe combines Peek, high-grade carbon fi bre and S-2 Glass fi bres that delivers low fatigue, improved buoyancy in fl uids and high resistance to corrosion compared to steel pipe. The pipe meets the demand for a hydraulic pumping
system that can handle high pressures and high fl ow rates, said the companies. “Peek’s high performance, and Victrex’s material
and processing expertise, have supported the new fl exible, spoolable M-pipe for the oil and gas industry,” said Charles Tavner, commercial director at Magma. Magma is offering its M-pipe and integrated
deployment package as a vessel back-deck system for rapid hydraulic light well intervention. “The Magma system is designed to minimise mobilisation time and maximise vessel utilisation by reducing hydraulic pumping time, reducing intervention costs by up to 30%,” he added. Magma says that Peek gives the M-pipe a number of benefi ts, including: the ability to handle high tempera-
