Langfang Tidepoch Building Material Co., Ltd. focuses on the production and global sales of construction materials, including non-load-bearing partition systems, suspended ceiling systems, cable support systems and various concrete admixtures.
Located in Langfang, North China’s key building materials industrial base, our company was founded 40 years ago, initially manufacturing galvanized metal furring channels. We have gradually expanded our product range to a full set of metal building decoration materials, such as light gauge steel furring channels, aluminum ceiling panels, as well as cable tray systems.
After 2000, the rapid development of real estate and infrastructure construction boosted local cross-border trade. With rich experience in the construction industry and international trade, we began to provide export agency services for local manufacturers. Our product line was extended to construction chemicals including cement admixtures and fibers. Our sales team has grown steadily, covering both self-produced product sales and the sourcing and export of qualified third-party building materials.
Benefiting from our prime geographical location and professional technical and sales teams, we have become a highly competitive supplier in the construction materials sector. Our factory is less than 100 kilometers from Tianjin Port, which effectively cuts inland logistics costs. Over four decades, we have been providing customers worldwide with reliable, cost-effective building materials and customized matching solutions under strict quality standards.
Our products are widely recognized by domestic construction companies and global overseas distributors. We strive to be a professional, trustworthy and competitive supplier in the industry, and look forward to establishing long-term win-win cooperation with you.
Hydroxypropyl Methyl Cellulose (HPMC) is derived from natural polymer raw materials and converted into non-ionic cellulose ether through a complete set of chemical modification processes. Retaining nearly all the functional characteristics of Methyl Cellulose (MC), HPMC stands as a preferred chemical additive for manufacturing high-performance, premium-grade construction materials.
Featuring outstanding water retention, excellent dispersibility and fast solubility, this cellulose ether additive effectively boosts construction efficiency and guarantees stable construction quality across various building projects.
Product Performance Features
Water Retention
HPMC significantly elevates the water retention capacity of cement and gypsum-based building materials. It effectively resolves common construction defects including rapid surface drying, incomplete hydration, insufficient hardening and structural cracking.
Workability
This additive improves mortar plasticity, optimizes on-site construction operability and raises the overall coating construction efficiency.
Adhesion
By increasing mortar plasticity, HPMC strengthens the bonding force between mortar and base substrates to deliver reliable interfacial adhesion.
Anti-slip Property
Benefiting from its remarkable thickening performance, HPMC prevents mortar slippage from base substrates during construction operations.
