FAQs
1. What are the main applications of expanded EPDM in China?
Expanded EPDM finds extensive use in automotive weather stripping, building seals, industrial gaskets, and various other applications requiring weather resistance and durability. The material’s versatility and properties make it suitable for a wide array of uses.
2. How does the density of expanded EPDM affect its performance?
Higher density EPDM offers greater strength and tear resistance but is less compressible. Conversely, lower density EPDM provides better cushioning and shock absorption but may have reduced durability.
3. What is the difference between closed-cell and open-cell expanded EPDM?
Closed-cell EPDM has a structure with no interconnected pores, offering superior water and air resistance. Open-cell EPDM has interconnected pores, allowing for better air permeability but less water resistance.
4. Are there any environmental concerns associated with expanded EPDM?
Expanded EPDM is generally considered environmentally friendly due to its long lifespan and resistance to degradation. However, responsible disposal practices are important at the end of its life cycle.
5. How can I choose the right type of expanded EPDM for my needs?
The selection process depends on the specific application requirements. Factors to consider include necessary strength, flexibility, chemical resistance, and temperature range. Consulting with a supplier will help determine the best fit.
