Kevlar and aramid gland packing are types of sealing materials used in various industrial applications to create effective and reliable seals in rotating equipment such as pumps and valves.
Ceramic Fiber Insulation products are great to use for standard insulating applications. It is used in industries such as the steel industry because of its ability to withstand high temperatures.
Packing, seal and gasket resists the flow of fluid from machinery face, head, joint and machinery gap or clearance. Packing materials: Fiber, asbestos, cotton, synthetic materials, plastic, Teflon, graphite etc.
There are two processes to make Carbon fibres; either the PAN or Pitch process. The PAN process produces the highest grade of Carbon Fiber with ultra-high modulus. 90% of the carbon fibre is made from the PAN process and the balance 10% is made from the Pitch Process.
For fluid sealing, different kinds of packings are used. Graphite packings and PTFE Packings are popular sealants generally available in braided style. The biggest difference between both these packings is that graphite is a naturally occurring form of carbon and PTFE is a synthetic material. Yarns go through multiple heat treatments to get the shape and structure of the desired characteristics of packings.
When choosing a polymer for their products, clients often have questions about PTFE vs. Teflon: what is the difference between the two?
