ALCOHOLS / ACID / ALKALI RESISTANCE

(A) In the Fields of Water Treatment

In the fields of water treatment, customers have to change from the factory waste fluids to the wastewater by adding acid and alkali. They are looking for tubing or hose which against various kinds of acid and alkali.

This tubing or hose is usually intended for:

A Transfer of Neutralizing Fluids in Wastewater

A Tubing or Hose for Chemical Pump

A Tubing or Hose for Acid and Alkali-Based Chemicals

Customers are looking for a hose that will not be hardened after transferring chemicals. Customers are also looking for a hose that shows resistance against acid and alkali.

(B)Alcohol (Industrial Use Only)

1. Less likely to be hardened

Compared with a PVC Hose, HAKKO KY Hose Series are less likely to be hardened.

2. Chemical Resistance

Although compared with Flexible Fluorine Resin Hose Series, the chemical resistance of HAKKO KY Hose Series is inferior. However, since the inner layer of HAKKO KY Hose Series is made of Olefin, it shows moderate chemical resistance. The following is the summary table from Chemical Resistance Data.

For full information on chemical resistance data, please go to Chemical Resistance Data.

However, for some chemicals (such as Nitric Acid, Hydrochloric Acid, and Sulfuric Acid), HAKKO KY Series is better than HAKKO Flexible Fluorine Resin Hose Series. This is because these chemicals are highly volatile, affecting the outer layer. Since Styrene (the Outer Layer of KY Series) is better than Polyurethane (the Outer Layer of Flexible Fluorine Resin Hose Series), we recommend HAKKO KY Series for some chemicals.

Demonstration

SITUATION
HAKKO KY Hose Series, especially KYS hose have been adopted by many alcohol-related customers such as alcohol, hand sanitizer gel manufacturing, and antiseptic solution manufacturing factories. In fact, alcohol is used for many applications such as aerosol and detergents.
CURRENT PROBLEM
Factory A, manufacturing alcohol gel, has been using PVC hoses to fill in the cooling gel. However, the black mold appeared on the final products. It turned out that the black mold came from the plasticizer of PVC hoses.
HAKKO SOLUTION
HAKKO recommended KYS hose, which does not have any plasticizer. Even after 6 months’ trial, there was no black mold on the final product.

As a result, Factory A decided to adopt KYS hose for cooling gel.
