melacoll hpmc merits

Longer than High lights

  1. Cold-water solubility. Easily dissolves in cold water, reducing your waiting time.
  2. Thickness. Increases viscosity and stability of liquids.
  3. Water retention. Extending the open time also helps cement hydration more fully.
  4. Lubrication. Improves workability and processing of cement.
  5. PH stability. Remains stable in the range of pH 3~11.
  6. Non-ionic. It is more stable in an aqueous solution.
  7. Thermal gelation. It turns into a gel when the temperature is too high, and when cools down, it turns into the liquid again.
  8. Air entraining. Helps increase mortar production and improve workability.
  9. Film formation. Waterproof and oil-proof.

One more independent RDP factory is under construction.

Your lead time and delivery time, how long is your factory production time?

So we will start stocking our production after we receive your 30% prepayment. And we will try to contact the shipping company to book a proper vessel for you with an estimated departure time of two weeks after your payment to make sure you can get your products as soon as possible. The production time of our factory is estimated at 7 days. We only need 7 days to prepare all your cargos and deliver it to the Qingdao port.

Our happy customers say everything. Customers will establish a long-term cooperative relationship with us. Plus the supervisor from the U.S. headquarters will regularly send QC inspectors to supervise our Production line( We have a quality prosecutor resident for long in the Chinese market. They are strict at every level ). Considering the Pandemic In recent months, all the quality inspections are carried out by local reports and conducted online. But there was no slack. We will send samples for random inspection regularly. If it fails, we will be required to limit the output.

Does your company accept to be audited by a survey company?

Of course, we welcome business building trip from your side and expecting that. We are willing to provide free samples for you if you have worked with the third party.

Why is the viscosity of your product higher than Dow or Ashland and Lotte?

The difference in viscosity between the two products is because Melacoll and Walocel adopt different production processes and raw materials. WALOCELL uses fine wood cotton, which determines its good water retention. While MELACOLL, using** refined cotton** as the raw material, has a thickening property twice that of ordinary products.

The intention we designed the high viscosity products is for saving customers' expenses. When the viscosity is high, the dosage does not need to be too large, which saves our clients' expenses.

How to inspect and verify your quality before loading?

We assure you the quality is the same as the samples and we are open to any inspection Audition from your side before loading. Generally, we have customers who have close cooperated company or agent in China who will inspect the audition and we have a whole after-sale and QC group to make sure we produce according to the standard.

We are well-established company seeking a long-term relationship with our customers, so we value our reputation and the good procurement experience from our Happy customers.

What is the inventory you normally keep? Or do you produce the materials only after the PO issued?

We keep dozens of tons of inventory in the peak season like March to May. We have had more orders recently which is why I need the estimated procurement plan from you so to arrange the mass production in advance in case we don't have enough inventory. Our factory is very efficient and is bound to complete your production plan within 5 working days..(we have 12 horizontal reactors and 6 vertical reactors each reactor can produce about 7 tons per day.)

How many direct vessels are sailing to Chennai in a month and what is the interval?

The vessel to Chennai is in depend. But from last month estimated 7 days per voyage(3 voyages in April/once per week). Now, however, due to pandemics, sometimes a shipping company will inform you that the ship is not coming one week, the reason of the epidemic. But it's roughly 3-4 trips, and it takes about 20 days to get to Chennai directly without transfer port.
