Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials /pipe fittings/injection moulds. Especially, Ehao Plastic Group is a leader of PVC/UPVC ball valves in the domestic market in China. Since its inception, the company has been supported of the Chinese Academy of Sciences and Zhejiang University in Technology, bridging the gap between scholastic polymer research and industrial application engineering.
We introduced high-precision production lines and computer automatic injection molding machines from Germany. Products go through 26 steps of scientific testing and are in the control of strict quality to ensure a 100% ex-factory pass rate. The technical indexes fully accord with DIN8077 and DIN8078 standards, reaching a world-class level of operational security and pressure tolerance.
By virtue of comprehensive advantages of large brand influence, excellent quality of products, and distinct marketing strategies, our products have covered most provinces and cities in China and other 28 countries and regions including Europe, America, and Southeast Asia. We win the praise from domestic and foreign merchants alike.
We also manufacture plastic moulds, supplying custom materials, samples, and structural layouts of plastic products (extrusion and injection products). Meanwhile, we can develop and make new products according to customers' requirements. Warmly welcome clients at home and abroad to co-develop long-term system portfolios.
From agricultural irrigation to complex civic infrastructure, our systems offer optimized structural integrity for diverse engineering demands.
Understanding formulation characteristics, UV stability index, and procurement standards in high-performance piping projects.
Under outdoor conditions, white or translucent polymer pipes undergo photo-oxidation. The ultraviolet (UV) spectrum of solar radiation breaks down molecular chains in regular PVC, causing micro-fissures and brittle fractures over time. Ehao's Black PVC Piping and Fittings are formulated with carbon black masterbatches acting as UV stabilizers.
This formulation blocks UV rays from entering the pipe wall, maintaining the tensile strength and impact resistance of the material. Tested under extreme exposure cycles, our black PVC exhibits a thermal degradation threshold that exceeds industry standards, making it the preferred material for outdoor industrial networks, exposed agricultural mainlines, and civil construction structures.
Global supply chains require logistics security and certified quality assurance. Large-scale procurement departments must manage tariff barriers, transport delays, and compliance issues. Ehao Plastic Group addresses these bottlenecks by utilizing German-engineered automated injection lines that minimize tolerance deviations.
By standardizing processes to DIN 8077 / 8078 parameters, we ensure that global engineering groups can source components from China and integrate them into existing international infrastructures without dimensional conflicts. Our close collaboration with the Chinese Academy of Sciences allows us to adjust raw material formulations to meet international environmental regulations, such as RoHS and REACH compliance, securing smooth customs clearance and environmental approval for infrastructure projects.

A zero-defect rate requires systematic testing. Every production batch of Black PVC Pipes & Fittings manufactured at Ehao's factories undergoes 26 steps of quality analysis. This testing suite includes:
These testing protocols are calibrated to DIN 8077/8078 standards, ensuring that Ehao valves and pipe connections perform reliably in demanding chemical transfer systems, industrial waste setups, and municipal distribution loops.
Looking ahead, Ehao is focusing on two development paths:
Bio-based Formulations: We are researching the replacement of traditional petroleum-based ethylene with bio-attributed raw materials. This reduces the carbon footprint of PVC production while maintaining identical physical performance profiles, helping our global partners meet ESG carbon-reduction goals.
Intelligent Flow Integration: With the expansion of IoT in agricultural and industrial fluid control, Ehao is developing integrated sensors for our ball valve assemblies. This will allow for the real-time tracking of flow rates, pressure fluctuations, and material wear, shifting piping infrastructure from passive containment to active, intelligent data points.
