EPDM-Good heat resistance and suitable for alkaline waste water,compressed air terpolymer(oil free) and chemicals,weather- resistance,good gas tightness except for hydrocarbon.
NBR-Oil and fuel quality,also suitable for gases,solvents and fats.
Polytetrafluoroethylene (PTFE) has a series of excellent performance:
High temperature resistance: long-term use temperature 200 ~ 260 degrees;
Low temperature resistance: still soft at - 100 degrees;
Corrosion resistance: resistant to aqua regia and all organic solvents;
Weather resistance: the best aging life of plastics;
High lubrication: with the smallest friction coefficient in plastics (0.04);
Non-stickiness: It has the minimum surface tension in solid materials and does not adhere to any substance;
Non-toxic: physiological inertia.
1. Flexibility: EPDM rubber expansion joints have excellent flexibility and can move smoothly and absorb vibration, reducing pressure on piping systems and equipment.
2. Corrosion resistance: EPDM materials have high corrosion resistance, making them suitable for a wide range of applications, including water treatment, chemical processing, and HVAC systems.
3. Easy to install: These expansion joints are designed to be easy to install, reducing downtime and labor costs during installation.
4. Cost-effective: EPDM rubber expansion joints are a cost-effective solution for many applications, providing long-term performance and durability.
1. Temperature limitations: EPDM materials have temperature limitations compared to other materials, which may limit their use in high-temperature applications.
2. Limited Compatibility: EPDM rubber expansion joints may not be suitable for applications involving certain chemicals or oils because the material may degrade over time.
3. Pressure Limitations: EPDM expansion joints may have lower pressure ratings compared to other materials and this should be considered when selecting the appropriate solution for your system.
Polytetrafluoroethylene (PTFE) uses industrial chemicals, petrochemical, oil refining, chlor-alkali, acid-making, phosphorus fertilizer, pharmaceuticals, pesticides, chemical fibers, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and polymer filter materials, high purity product production (such as ionic membrane electrolysis), transportation and operation of viscous materials, hygiene. Highly demanding food and beverage processing and production departments.
In strict accordance with international standards and raw material quality requirements, HEBEIXINQI has put an end to jerry-building and material reduction. Environmental protection standards, that is, raw materials of products need not only new materials, but also new materials of environmental protection level.
Rubber joint has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, oil, light and heavy industry, refrigeration, health, water heating, fire protection, electric power and other basic projects, especially for pipelines with large vibration and frequent changes in heat and cold.
