Formulation and compounding
Polyol systems for one-component foam, compounded in Hangzhou, one batch number per blend, two years of retained samples.
About
We formulate in Hangzhou. You build the brand where you sell.
A short page, because a supplier page should answer one question: is this a real entity that will still be here next year?
What we do
Three activities, and nothing else
Filling process support
SOP, parameter cards, troubleshooting and training, written against the line you actually run.
Export documents
SDS, COA, Form E and transport appraisal prepared before booking, not after the container is at the port.
Application centre
What we can test before we ship
Four tests on retained samples: free-rise density, compression at 10%, adhesion on aluminium and dimensional stability over 48 hours. If your specification needs a test we cannot run, we say so before the order.
We serve the CIS and Southeast Asia. Other markets are assessed case by case — not because we would refuse, but because the documents and the logistics change.
Contact
The same details as the footer, and the same details as the contract
Company name, address, email and phone are identical to the footer — because a supplier page that contradicts its own footer is the first sign to walk away.
