Jinghan Medical Materials' Application of PP Material in Biopharmaceuticals for Experimental Consumables 2026-02-27 Jinghan Medical Materials' Application of PP Material in Biopharmaceuticals for Experimental Consumables Jinghan Medical Materials' use of PP (Polypropylene) material in biopharmaceutical applications—for consumables like centrifuge tubes, cryovials, and pipette tips, as well as for equipment like single-use bioreactors, storage bags, and filters—offers distinct advantages and benefits that can be analyzed from several key perspectives: In the Field of Experimental Consumables (Centrifuge Tubes, Cryovials, Pipette Tips) 1. Excellent Chemical Inertness and Purity Advantage Analysis: PP material exhibits exceptional chemical stability. It resists strong acids, strong bases, and various organic solvents (such as ethanol). When in contact with diverse biological reagents or cell culture media, it does not undergo chemical reactions or leach impurities. Core Benefit: This ensures the purity of experimental samples, preventing foreign substances from interfering with experimental results or affecting cell growth. This is particularly critical in molecular biology experiments. 2. Superior Low-Temperature Performance Advantage Analysis: PP has a very low glass transition temperature. It maintains good toughness even in ultra-low temperature environments like -80°C or liquid nitrogen (-196°C), unlike other plastics that may become brittle and crack. Core Benefit: This is fundamental for cryovials to safely store cells and tissue samples. It guarantees that sample containers will not fracture under ultra-low temperature conditions, ensuring the long-term, safe preservation of valuable biological materials. 3. Good Transparency and Hydrophobicity Advantage Analysis: While PP is not as transparent as glass or PS, it offers good translucency, facilitating liquid level observation. Additionally, the PP surface is naturally hydrophobic. Core Benefit: During pipetting, the hydrophobic surface helps minimize the retention of expensive reagents (such as antibodies or enzymes) on the inner walls of pipette tips. This improves pipetting accuracy and reduces experimental errors. 4. Resistance to High-Temperature and High-Pressure Sterilization Advantage Analysis: PP has a melting point exceeding 160°C, allowing it to withstand autoclave sterilization at 121°C. Core Benefit: Experimental consumables can be sterilized and reused safely, ensuring an aseptic operating environment while reducing the cost of repeated purchases. This is vital for experiments requiring strict sterility, such as cell culture. In the Field of Pharmaceutical Equipment (Single-Use Bioreactors, Storage Bags, Filters) 1. Core Carrier for Single-Use Systems, Eliminating Cross-Contamination Advantage Analysis: Single-use storage bags and bioreactors made from PP film (or multilayer films containing PP) are central to single-use technologies in biopharmaceutical manufacturing. They are designed for one-time use and then discarded, eliminating the need for cleaning and sterilization validation. Core Benefits: Reduced Contamination Risk: Completely avoids batch-to-batch cross-contamination that can occur with traditional stainless steel vessels due to inadequate cleaning. This is especially beneficial for multi-product manufacturing lines. Increased Production Efficiency: Eliminates the tedious steps of Clean-in-Place (CIP) and Sterilization-in-Place (SIP), significantly shortening production turnaround times between batches. 2. Ensures the Activity and Stability of Biological Products Advantage Analysis: PP material is inherently non-toxic, has no leachables, and offers good gas barrier properties (especially when combined with materials like EVOH in multilayer films). Core Benefit: When in direct contact with cell culture media, buffers, or drug substance (DS), PP does not inhibit cell growth or adsorb proteins. This ensures the activity and stability of critical biomolecules like monoclonal antibodies and vaccines. 3. Weldability and Mechanical Strength Advantage Analysis: PP exhibits excellent heat-welding properties, allowing it to form strong, sealed connections with tubing, connectors, and other components. Core Benefit: Guarantees the integrity and leak-proof nature of the entire single-use bioprocess system, from liquid preparation, filtration, and storage to transport. The bag material can withstand certain mechanical stress from pumping or agitation without easily rupturing. 4. Regulatory Compliance and Stable Supply Chain Advantage Analysis: PP materials provided by specialized medical material suppliers like Jinghan typically meet stringent biocompatibility standards, such as USP Class VI or ISO 10993, and come with full traceability documentation. Core Benefit: This provides robust support for pharmaceutical companies during regulatory inspections by agencies like the FDA (U.S. Food and Drug Administration) or NMPA (National Medical Products Administration) , significantly reducing compliance risks associated with drug registration.

PP Welded Aquaculture Tanks: A New Eco-Friendly and Safe Choice for Modern Aquaculture 2025-12-31 PP Welded Aquaculture Tanks: A New Eco-Friendly and Safe Choice for Modern Aquaculture Amid the wave of transformation towards intensive and intelligent aquaculture, PP welded tanks are becoming core equipment for industry upgrading, thanks to their unique material advantages and structural characteristics. These tanks, made from polypropylene (PP) as the base material and seamlessly joined through hot-melt welding technology, not only address the pain points of traditional tanks—such as susceptibility to corrosion and high maintenance difficulty—but also achieve comprehensive breakthroughs in environmental friendliness, cost-effectiveness, and functionality. 1. Corrosion Resistance: Solving Water Quality Pollution Challenges PP sheets far exceed traditional concrete and metal tanks in their tolerance to acids, alkalis, salts, and microorganisms. The stable carbon chains in their molecular structure effectively resist erosion from corrosive substances in water, such as ammonia nitrogen and hydrogen sulfide. Experimental data show that PP sheets can maintain structural integrity even in extreme water environments with pH levels ranging from 2 to 12, with a service life of over 10 years. For example, after a whiteleg shrimp farm in Guangdong adopted PP welded tanks, the corrosion rate of the tank bodies decreased from 0.3 mm per year in traditional concrete tanks to 0.02 mm, completely eliminating the risk of cross-contamination caused by tank leakage. 2. Modular Design: Reconstructing Aquaculture Space Efficiency PP welded tanks are produced using standardized modules and can be assembled quickly, much like building blocks. The dimensional accuracy of individual sheets is controlled within ±1 mm, and seamless connections are achieved through welding, reducing construction time by 70% compared to traditional concrete tanks. An industrialized aquaculture base in Yancheng, Jiangsu, customized circular tanks with a diameter of 12 meters and a depth of 2 meters using the malleability of PP sheets. Combined with a recirculating aquaculture system (RAS), the yield per unit area increased to four times that of traditional ponds. Notably, the modular design supports flexible expansion and relocation of the tanks. One enterprise increased its original aquaculture scale by 30% within 48 hours by adding PP modules, fully demonstrating its adaptability to market fluctuations. 3. Environmental Performance: Practicing Green Aquaculture Principles As a food-grade eco-friendly material, PP sheets are produced without the addition of heavy metals and are recyclable after disposal. Compared to concrete tanks, PP tanks eliminate the need for plastic products like impermeable membranes, reducing microplastic pollution at the source. After adopting PP sheets, a grouper farm in Fujian saw a 42% reduction in total phosphorus content in the water, with aquaculture effluent meeting discharge standards after simple treatment. Additionally, the low water absorption and smooth surface of PP sheets make them easy to clean, effectively preventing algae growth on the tank walls and reducing the use of chemical pond-cleaning agents. This provides a safer growth environment for aquatic products. 4. Economic Analysis: A Smart Choice for Long-Term Returns Although the initial cost of PP tanks is 20%–30% higher than that of concrete tanks, their advantages in lifecycle costs are significant. For example, in a 1,000-cubic-meter aquaculture tank, the annual maintenance cost of a PP tank is only one-fifth that of a concrete tank, with no need for periodic shutdowns for repairs. A tilapia farm in Shandong found that the energy consumption per unit yield of PP tanks was 18% lower than that of concrete tanks, the survival rate of aquatic products increased by 12%, and overall profits improved by 25%. More importantly, the standardized production model of PP tanks enables farms to quickly replicate successful practices. A chain aquaculture enterprise, by uniformly adopting PP tanks, reduced the construction period for new bases from six months to two months, significantly enhancing its market responsiveness.
