The core demands of the pharmaceutical and food industries are safety, cleanliness, and compliance. As the "protective barrier" of production equipment, the sealing system is directly related to material purity and product quality. PTFE sealing components (with polytetrafluoroethylene, PTFE, as the core base material) have become the preferred sealing choice for these two industries due to their outstanding properties, providing reliable protection for the entire production process.
I. PTFE Sealing Components: Core Properties Meeting Industry Needs
Polytetrafluoroethylene (PTFE), the core base material of PTFE sealing components, is known as the "King of Plastics" for its excellent performance. The superior properties derived from its unique molecular structure precisely meet the strict requirements for sealing materials in the pharmaceutical and food industries.
It boasts extreme cleanliness, being non-toxic, odorless, and free of substance leaching, and does not react with materials, thus ensuring product purity. Its corrosion resistance is equally prominent—it has absolute resistance to strong acids, strong alkalis, organic solvents, and food additives, making it suitable for complex working conditions such as reaction kettles and fermentation tanks.
In terms of temperature adaptability, it can maintain stability in the range of -200°C to 260°C, withstanding both 121°C steam sterilization and low-temperature refrigeration equipment requirements. Meanwhile, its friction coefficient is only 0.04; the low-friction and self-lubricating properties reduce equipment wear, lower energy consumption, and prevent material contamination from friction-generated debris. Its easy-to-clean feature, characterized by non-stick and low adsorption surface, facilitates cleaning and sterilization, reducing maintenance costs.
In addition, PTFE sealing components modified by filling with carbon fiber, graphite, etc., also possess anti-creep and anti-cold flow properties, which can maintain tight fitting of the sealing surface for a long time and eliminate leakage risks.
II. Customized Solutions: Covering Full-Scenario Applications
To meet the diverse needs of the industries, we provide a full range of PTFE sealing components for precise adaptation:
1. Applications in the Pharmaceutical Industry
Mascot's spring-energized seals and gaskets can be used for shaft seals and flanges of reaction kettles; their PTFE material ensures corrosion resistance and prevents leakage. In fluid transportation, Mascot's O-rings and sealing tapes are suitable for pipelines and valves, withstanding repeated sterilization.
2. Applications in the Food Industry
In processing equipment, Mascot's PEEK gaskets can withstand high temperature and pressure due to their properties, making them suitable for door seals of sterilization kettles. O-rings can be adapted for contact parts such as filling machines and dairy equipment; PTFE is non-toxic and odorless, so it will not affect food flavor. The special working condition of cold chain equipment lies in the low-temperature environment, and Mascot's low-temperature PTFE sealing components are perfectly suitable for this demand. Widely used in cold storage doors, these sealing components effectively prevent cold air loss and ensure refrigeration efficiency.
PTFE sealing components are the "safety line of defense" for the pharmaceutical and food industries. With high-quality products and customized solutions, Mascot provides safe and compliant sealing guarantees for enterprises, helping to safeguard the pure quality of pharmaceuticals and food.
