Acrylic
Used as Alternative to polyester when hydrolysis is a problem maximum 125c under conditions - used in the cement and limestone industries in power generation, and asphalt industries.
Liquid Strainer
Lydall Industrial Filtration offers a comprehensive range of strainer felts designed to cover a very wide range of liquid filtration applications.
Meta Aramid
Meta Aramid is a high temperature fiber, suitable up to 200°C in dry conditions; care is needed when used in moist environments at high temperatures as it is prone to hydrolysis which will chemically degrade the fibers turning them to powder resulting in failure of the filter medium.
Polyester
Polyester 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 oxidizing agents.
Polyimide
Polyimide, also known as P84, is a high temperature fiber which under dry conditions can be operated up to 230°C.
Polypropylene
Polypropylene is the lowest rated common fiber as far as temperature is concerned, but it exhibits one of the best chemical resistances, properties which match well with many specialist industries.
PPS
PPS is a high temperature fiber, up to 180°C, with excellent chemical resistance except for oxidizing agents such as NO2 and Oxygen itself.
PTFE
PTFE is the 'ultimate' regular fiber as it has outstanding chemical and thermal resistance, with the right chemistry, it will operate up to 250°C.
