PolypropylenePP is the lowest rated common fibre as far as temperature is concerned, but it exhibits one of the best chemical resistances, properties which match well with many specialist industries. Under dry, non-aggressive conditions it will operate continuously at 90-95°C. It is a very low density fibre (it floats in water) and as a consequence it tends to produce quite thick felts for a given area weight; around 30% thicker than polyester. Due to their chemical structure, the fibres don't hydrolyse, their weakness is a susceptibility to oxidation, so care is needed if strong oxidising agents are present. Read More
PolyesterPolyester is the most versatile, most cost-effective and most widely used filter media for dust collection. It is strong, abrasion resistant can work up to 150°C and has good resistance to common acids, solvents and oxidising agents. Its one weakness is a tendency to hydrolyse which results in a loss of strength and toughness as the fibres break down and turn to powder. Polyester, being a 'commodity' fibre, is available in a significant range of deniers (effectively diameters) and so a wide range of needlefelt products can be designed to match the demands of the filter; from very high collection efficiency (with very fine fibres) to low efficiency products (using coarse fibres) where flow is more important than collection. A wide variety of chemical and thermal treatments are available for polyester, the most common being superglaze to improve dust release and liquid repellency to assist with sticky dusts. Read More
AcrylicAcrylic normally refers to homopolymer products in this industry, but there are small amounts of copolymer used where the conditions are less arduous and price is an important consideration. It is a medium temperature fibre, up to 120°C continuous, and has good chemical resistance as its structure imparts resistance to hydrolysis. It is a fibre with a quite a low strength so care is need in mechanically stressed systems. This weakness is increasingly being tackled by mixing the fibre with polyester to produce a compromise needlefelt. Read More
AramidAramid is a high temperature fibre, up to 200°C, with excellent chemical resistance except for oxidising agents such as NO2 and Oxygen itself. It has very good acid resistance and this, together with a good thermal resistance has led to wide acceptance in combustion processes. Read More
Polyphenylene sulfidePPS is a high temperature fibre, up to 180°C, with excellent chemical resistance except for oxidising agents such as NO2 and Oxygen itself. It has very good acid resistance and this, together with a good thermal resistance has led to wide acceptance in combustion processes. The fibre is actually 30% sulphur by weight and it has a very high limiting oxygen index (34) when compared with the volume fibres. Read More
PolyimidePolyimide, also known as P84, is a high temperature fibre which under dry conditions can be operated up to 240°C. It also benefits from a tri-lobal cross section which greatly enhances its filtration efficiency to the point that it is sometime used with much less expensive fibres to boost dust collection. In this application it usually forms a cap on the surface of the felt to exploit this property effectively. It is a fibre with good chemical and thermal resistance, with only PTFE really exceeding it. Some care is needed with oxidising agents such as NO2 and the fibre can be sensitive to hydrolytic attack in hot wet conditions. Read More
PolytetrafluoroethylenePTFE is the "ultimate" regular fibre as it has outstanding chemical and thermal resistance, with the right chemistry, it will operate up to 250°C. Read More
