Frequently Asked Questions
How to select proper viscosity of HPMC?
A: 100,000‑200,000 mPa·s is recommended for tile adhesive & wall putty. 400‑5,000 mPa·s is suitable for self‑leveling compounds. Samples are available for formulation test.
Can this HPMC work under 5℃ winter construction?
A: Yes. It provides stable performance at low temperatures, preventing premature drying of the mortar.
What is the storage requirement and shelf‑life?
A: It has a 24-month shelf-life under cool, dry conditions below 30℃. Please keep the package sealed after opening.
What is the raw material source of GinShiCel HPMC?
A: It is produced using 100% Xinjiang high-quality refined cotton as the raw material, featuring a triple sieving process, no agglomeration, and fast cold-water dissolution.
What certifications and qualifications do your products hold?
A: Zhejiang Haishen is ISO9001 certified, compliant with EU REACH regulations, recognized as a National High-Tech Enterprise, and has an in-house R&D and application lab.
What are the packaging options and minimum order quantity (MOQ)?
A: Standard packaging is a 25kg kraft bag with PE inner liner, and bulk packaging is 500kg/1000kg FIBC jumbo bags. The MOQ is 1kg for trial samples and 1MT for bulk wholesale orders.
