About this product

Product information from the supplier.

Hydroxypropyl Methylcellulose (HPMC) is a high-performance, non-ionic cellulose ether derived from natural polymer materials. Engineered for versatility, it serves as a critical additive across diverse industrial sectors, offering exceptional thickening, stabilizing, and water-retention properties. Whether utilized in personal care formulations or heavy-duty construction materials, our HPMC ensures superior consistency and structural integrity in every application.

Depending on the specific industrial requirements, HPMC is categorized into two primary types: Instant Dissolving and Hot Dissolving. While the instant type is optimized for room-temperature solubility in detergents and cosmetics, the hot dissolving variant is specifically engineered for high-temperature stability in the construction and ceramic industries, ensuring optimal workability and long-term durability for professional-grade mortars and putties.

Frequently Asked Questions

Q: What is the difference between instant dissolving and hot dissolving HPMC?

Instant dissolving HPMC can be dissolved in water at room temperature and is ideal for detergents, shampoos, and cosmetics. Hot dissolving HPMC requires water above 60°C and is primarily used in construction, ceramics, and textiles for water retention and thickening.

Q: How can I verify the purity of the HPMC powder?

Purity can be checked in three ways: 1. Ash Ratio: Burn the powder; a ratio under 5% indicates higher quality. 2. Weight: Higher purity leads to higher density. 3. Fluidity: Purer powder exhibits a smoother, more fluid movement when rolled in a glass jar.

Q: In which construction applications is HPMC most effective?

It is highly effective in Tile Adhesive Mortar, EIFS Mortar, Outdoor Block Bonding Mortar, Self-leveling Slurry, and Wall Putties, where it prevents cracking, drooping, and powdering.

Q: Can HPMC be used in the cosmetic industry?

Yes, the instant dissolving type of HPMC is widely applied in shampoos, liquid soaps, toothpastes, and other personal care products as a thickener and emulsifier.

Q: Do you provide samples for testing before bulk purchasing?

Yes, we provide free samples to ensure quality stability. We can provide samples from different batches, with the air shipping cost covered by the buyer.

Q: How does HPMC improve the "open time" of mortar?

HPMC acts as a superior water retention agent, preventing the mortar from drying too quickly. This extends the open time, allowing workers more time to apply and adjust the material before it sets.
