Through-out the years, we have developed an effective cleaning result monitoring.  We are using IC tester as our sponge cleanliness monitoring tool.  Our sponge will send for IC test, this is to ensure all the residual in the sponge has been fully removed and maintained at a very low level.

Besides the IC tester, we do have a Liquid Particle Counter (LPC), we are using the LPC to monitor various particle size quantity leach out from the sponge.  With both IC tester and LPC tester, we are able to monitor our sponge cleanliness quality.

Critical Material Not Allow in our Process

We have many years working with various industry, we know there are several materials which are totally not acceptable by the industry.  While other still struggling on finding the appropriate substitution, in DST, we are very sure these 2 materials are not allowed in our process.  We are confident to say that our product is

• Silicone oil free
• Amide free

This is because we know that it will become very challenging in order to remove silicone oil and Amide in the cleaning process.

Water Treatment Process

Maintain a quality PVA sponge roller product is the important criteria in order to get more customers; however, we need to comply with the environmental friendly process for sustaining in the industry.  We have established up to standard wastewater treatment plant to show our commitment.

In PVA sponge roller process, it needs to consume high water usage.  There are many contaminants in the wastewater, and Formaldehyde residue is most critical for disposal.  Instead of direct discharge the wastewater, we drained the wastewater to our wastewater treatment plant for primary contaminant treatment.  The treated wastewater will further hand over to outsource secondary wastewater treatment plant for disposal.
