Quality is in Our DNA: The TENESSY Promise of Consistency & Excellence

At TENESSY, we believe that superior quality isn’t just a step in our process—it’s the foundation of everything we do.

As a leading manufacturer of cellulose ethers like HPMC, HEC, HEMC, and RDP, we understand that the performance of your products depends entirely on the consistency and reliability of our raw materials.

That’s why our multi-layered Quality Control system is designed to deliver nothing less than perfection, batch after batch.

How We Check for Quality: Our 4-Step Process

We don’t just test the final product; we build quality into every single step of our manufacturing journey. Our philosophy is one of proactive prevention, not just reactive detection.

1. We Check Every Raw Material

• Stringent Sourcing: We partner with trusted suppliers for high-purity raw cellulose.
• Meticulous Checks: Every incoming shipment is rigorously tested for key parameters like moisture content, purity, and viscosity potential before it ever enters our production cycle.

2. We Watch the Production Closely

• Real-Time Monitoring: Throughout the etherification, purification, and drying phases, our automated systems and dedicated technicians continuously monitor critical variables such as temperature, pressure, and reaction times.
• Intermediate Testing: Samples are taken at key stages to ensure the chemical reaction is proceeding as specified, allowing for immediate adjustments if needed.

3. We Test the Final Product Thoroughly

• Comprehensive Analysis: Every single batch of our finished products—whether HPMC, HEC, HEMC, or RDP—undergoes a full battery of tests in our advanced laboratory.
• Key Parameters Tested: We verify a wide range of properties to ensure they meet both international standards and your specific requirements:Viscosity & Gel Point, Moisture Content, Ash Content, Purity.

4. We Keep Track of Every Batch

• Complete Batch Records: Every product can be traced back to its raw material source and production date, ensuring full transparency.
• Certificates of Analysis (CoA): You receive a detailed CoA with every order, providing you with the verified data and peace of mind that our products conform to agreed specifications.
