The leakage of transformer occurs mostly around the gasket, which is mainly caused by the aging and cracking of gasket. The quality of depends mainly on its oil resistance. The poorer oil resistance, the faster aging rate. Especially under high temperature, the aging speed will be faster and easily lead to aging and cracking of gasket, resulting in oil leakage. When overhauling oil-resistant and h...
Tetrafluoro-flange gasket is a kind of non-metallic gasket, which is generally composed of two parts: cladding layer and embedded material. The cladding layer is corrosion resistant and is usually made of polytetrafluoroethylene (PTFE) with inserts (fillers) that are more resilient and are usually asbestos rubber sheets. The sealing gasket can be made into V-shape, U-shape and L-shape according to...
In order to adapt to different conditions of use and obtain different properties, and to improve the performance of rubber products and reduce the cost, different additives must be added into the raw rubber.Rubber mixing and refining is a process in which the plasticized raw adhesive is mixed with the binder and put in the mixer to make the binder completely and uniformly dispersed in the raw adhe...
Rubber gaskets are innovative mechanical rubber seals that ensure the prevention of leaks between two surfaces. This blog will guide you detailed introduce the basics of gaskets . What is a gasket? An EPDM gasket seal fills a space between two substrate sections to avoid leaks. It is usually a shaped sheet o-ring that will cap the intersection between two surfaces. This flexible component can be u...
When you looking for a high performance gasket, rubber seals often lack the ability to remain durable if an application comes in contact with oils. For these situations, consider using gaskets made of Nitrile Butadiene Rubber, also known as oil resistant rubber - NBR. Nitrile Butadiene Rubber is one of the few rubbers that are particularly resistant to petroleum, mineral, and vegetable oils,...
There are various techniques that can be used in order to create a rubber gasket that ideally fits the purpose of use and provides a solution to an assortment of problems including gasket cutting, gasket punching and rubber moulding. Here at Fuste Rubber, we create all of our rubber gaskets through the process of rubber moulding. This method takes raw rubber compound, places it into a mould, then ...
