POTOP CO .,LTD. (hereinafter referred to as "POTOP"), established in 2009, is a company engaged in the manufacturing of polymer rheological characterization instruments, processing and molding experimental equipment, as well as R&D and testing equipment for functional film forming technologies.
POTOP offers a comprehensive range of polymer experimental instruments and equipment, including rheological characterization instruments such as torque rheometers, extrusion capillary rheometers, and pressure filtration value testers; processing and molding experimental equipment such as desktop small-scale precision casting machines, desktop small-scale precision calendering machines, desktop small-scale precision film blowing machines, small-scale precision multi-layer co-extrusion film blowing machines, small-scale precision multi-layer co-extrusion casting machines, small-scale precision multi-layer co-extrusion calendering machines, small-scale precision multi-layer in-mold/out-mold composite machines, and film biaxial stretching machines.
With the rapid development of industries such as lithium batteries, photovoltaics, hydrogen energy, marine engineering, aerospace, healthcare, and 5G mobile communication, functional films have become critical substrates for high-tech products. To adapt to market changes, POTOP has intensified R&D efforts in novel functional film forming and testing equipment. The company now possesses the capability to manufacture a variety of complete functional film testing systems, meeting the demands of domestic and international clients. Over the past decade, POTOP has delivered over 600 customized functional film testing lines, each uniquely tailored to client specifications, solidifying its position as a leading supplier in this field.
POTOP prioritizes technological innovation, dedicating 20% of its annual sales revenue to R&D. The company has established the Panyu Sub-Center in collaboration with the National Engineering Research Center for Novel Polymer Processing Equipment at South China University of Technology (SCUT). Together, they have undertaken multiple national and provincial-level research projects, including major instrument development initiatives. POTOP serves as a production base for polymer processing rheometers and their application development. The company emphasizes scientific research, operating specialized laboratories such as the Extrusion System Lab, Dynamic Stress-Strain Characterization Lab, and Film Stretching Process Technology Lab, alongside four product development departments. POTOP has completed dozens of major technological developments, filed over 100 patents (including 9 authorized invention patents), and maintains a strong focus on innovation.
POTOP places client needs at the forefront, striving to be a 24/7 supplier of high-quality, safe, and user-friendly experimental equipment. As an open and learning-oriented company, POTOP provides customized solutions, technical alignment, and pre-sales testing services. Safety is paramount: electrical systems meet safety standards, heating elements prevent burns, and mechanisms avoid pinch hazards. For ease of maintenance, many components are designed for tool-free disassembly and installation. POTOP also maintains on-site technical teams to offer pre-sales testing, equipment calibration, on-site debugging, and 48-hour responsive after-sales services, ensuring seamless client research operations.
Functional film forming processes are often uncertain, immature, or incomplete, posing significant R&D risks. Testing equipment serves as the "mother machine" for R&D, and process trials are critical before mass production. To ensure successful collaborations, POTOP evaluates clients based on three criteria: organized R&D workflows, strong professional teams with incentives and dedication, and sufficient R&D funding. Clients meeting these criteria achieve higher success rates, enabling POTOP’s equipment to fulfill its role as a foundational R&D tool.
POTOP is recognized as a high-tech enterprise, a "Specialized, Refined, Distinctive, and Innovative" (SRDI) company, and an ISO9001-certified organization. "Integrity and dedication" define our ethos, while "customer satisfaction" drives our mission. We deliver the best products and services to meet your needs.
