arker has obtained NORSOK M-710 qualification for 25 polymer compounds intended for applications in the oil and gas industry. The range of material compounds for this market includes Nitrile Rubber (NBR), Hydrogenated Nitrile Rubber (HNBR), Carboxylated Nitrile Rubber (XNBR) and Fluorocarbons (FKM, FFKM), Polyetheretheketones (PEEK) and Polytetrafluorethylene (PTFE) formulations. Parker seal material compounds developed from these polymer groups have been qualified against NORSOK M-710 rapid gas decompression (RGD) and sour gas test. The testing was conducted by MERL Ltd.

hemique Adhesives and Sealants Ltd have announced the launch of a new simplified Solfre2 range. The company has specialised in the development of solvent free adhesives for the construction industry. The new range falls into three key types with each providing a number of different open times to suit the individual application. Solfre2 GP is the general-purpose formulation, which can be applied using either spray or bead. Solfre2 HC has been formulated specifically for honeycomb panelling and can also be used with either spray or bead. The third grade is HCR which is an alternative rollable version of the HC. All of these products are termed environmentally friendly and have a two-part performance
