Gasket material RF34, RF46
Thread Content
Does anyone know what materials RF34 and RF46 refer to? There is a saying that \"wear-resistant fluoroplastic\"”
RF does not indicate the material; it merely indicates that this gasket is used for convex flanges. The material needs to be determined, as well as other parameters； The entire plane is denoted by FF ； Convex-concave face flanges are denoted by MFM ； The tenon and mortise surfaces are denoted by TG
Please refer to the attached diagram; RF46 corresponds to the material column, and it is likely an abbreviation for some type of material.
The patent holder’s number? Is it still the design institute’s code? I need to ask where it comes from; this shouldn’t be a generic code name
I asked the manufacturer: RF46 material is expanded PTFE with barium sulphate filler; RF34 consists of glass fibers with PTFE, and PERBU is an abbreviation for Perbunan (NBR – Nitrile Butadiene Rubber).
