Nylon might be a suitable replacement, or brass, steel, aluminium or....
Glass fibre printed circuit board material... !

Consider having the plate made out of Turcite. Very expensive plastic, but will out wear just about anything, with friction less than teflon. Caution, if you machine it yourself be careful because it is so slippery that it is difficult to hold on to.

what is this turcite?

what are the qualities of this material

how much expensive it is

where does it use so that i can search for the supplier

is it same like hylum

phenolic and hylum is the same material or different

i use glass fiber mixed teflon in my mechanical seal but it makes the shaft to worn out may be it will cause to worn out my chain which is more expensive because it is special finger type of chain

my packing material is abrasive powder which is the major problem of my packing line

please advice me

Stop trying to identify the properties of an unsuitable material!!!

Identify what properties you require and then try to find a suitable material...

If the Hylum is wearing out that much quicker and the cartons that you are packing haven't changed and your through put hasn't changed, then the hylum has changed.

I would be keen to talk to your supplier about the change in the specification of the goods he is supplying. It maybe possible to return to the original material or even upgrade the durability of the hylum.

Alternatively you could go with one of Del's suggested materials. Is there some reason that a metal part could not be used?

Have you considered re-coating of the worn material?

It maybe possible to metal spray the flat surface if that is the worn part or re-bush the holes if that is the problem.

Did you mean Hylam based on thermosetting phenol formaldehyde resin familiarly known as Phenolic. Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.

You may need to try various types of Phenolic composites available to over come the problem of wear.

Sandeep, We do surface modification of tools made of metals to increase their wear resistance. Please visit: www.technovation.ws for more information on what we do. Not being an engineer in your field, I tried to "CUIL" hylum and got no where except a lot of botanical sites. If your tooling is metallic, I can help you. Dr. Ram K. Iyengar technovationsintl@gmail.com
