End-User Description

Chemap® filters solve filtration tasks in a simple and economic way. They are especially suited to demanding filtration applications in which the drying, extraction, heel volume filtration, washing and sterile process control are integral parts of the filtration. These filter systems are used in the fields of environmental protection, foodstuffs, pharmaceuticals, chemicals, nuclear and hydro-metallurgy.

The Challenge

Since we are very broadly positioned and the Chemap-Filter can cover many applications, we need a gasket that we can use in a versatile and flexible way. Since our customers can also filter several products in one Chemap-Filter, we have to design the filters in such a way that the seals also meet these requirements.

The Solution

For most systems we use Durlon® 9000 but we also finding the need for Durlon® 9400 and at times, Durlon® 8500. For us it is very important that we do not have too many different sealing materials, so that we can standardize the gaskets.

The Customer’s Findings

With the Durlon® 9000 gaskets we are very well equipped to cover all applications and do not have to worry about any problems. So far, we have never had a complaint.

The Benefits

Durlon® 9000 is for use in process piping and equipment in chemical, pulp & paper, food & beverage and other general industrial applications where resistance to highly aggressive chemicals is required. In addition, the shape of the fillers do not allow wicking which can cause corrosion on flange surfaces and conforms to FDA requirements.

Durlon® 9400 is a high performance filled PTFE gasket material designed for use in piping and equipment, chemical, and other general industrial applications where resistance to highly aggressive chemicals (including hydrofluoric acid) and conductivity (for ATEX) is required.

Durlon® 8500, a high-performance compressed gasket material suitable for oils, water, steam, new generation refrigerants, dilute acids and alkalis, and many other liquids and gases.
