Chemical Resistant Hose/Tubing
Many customers transfer chemicals in their applications, but they are quite not sure whether or not their hose or tube is suitable for their applications. The chemical resistance varies depending on the hose material (type of resin).
If the hose is deteriorated in a short period of time, such as hardening, swelling or discoloration, it is time to consider to review the hose/tube and choose a hose/tube with better chemical resistance. The frequency of hose change will go down if the hose/tube, suitable for fluid (chemical solution), is chosen.
The below picture shows before and after MEK (Methyl Ethyl Ketone) is transferred.
Above the picture, you can easily find that a hose without enough chemical resistance is damaged so quickly.
For your information, frequent used chemicals at chemical factory are as follows:
(A) Thinner
(B) Adhesives
(C) Solvents
(D) Sodium Hypochlorite
(E) Benzene
(F) Surface Coating Liquid
(G) Drum Coating Liquid
When you check the chemical resistance of our products, please refer to the chemical resistance data.
If the chemicals used may be the name of the product or the mixture, and may not be listed in our chemical resistance data, please contact us from below. We can also provide a hose sample for chemical inclusion test.
Adoption Example
Current Problem: Low Duration of the Hose Situations: Company A has been using a PVC hose for transporting water-based paints. However, they have to replace into a new hose frequently, which reduces the efficiency of production.
HAKKO Solutions: Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose [Model Number: E-SJSP]
Since Company A requests a hose with high stability and high chemical resistance against water-based paints, we offer E-SJSP. Company A is satisfied that the efficiency of production greatly improves.
