The difference between PE/EVA foam sealing tape

PE (polyethylene) and EVA (ethylene-vinyl acetate) foam sealing tapes have significant differences in material properties and application scenarios. The following are the main differences:
1. Material properties
1) PE foam sealing tape:
Material: polyethylene.
Softness: good, moderate elasticity.
Temperature resistance: general, usually between -40°C and 90°C.
Chemical resistance: good, water-resistant, acid-resistant and alkali-resistant.
Density: low, light texture.
2) EVA foam sealing tape:
Material: ethylene-vinyl acetate.
Softness: excellent, good elasticity.
Temperature resistance: good, usually between -50°C and 120°C.
Chemical resistance: excellent, oil-resistant and solvent-resistant.
Density: high, dense texture.
2. Application scenarios
1) PE foam sealing tape: can be used for home decoration: such as fixing picture frames, photos, etc.
Packaging: used to cushion and protect fragile items.
Electronic products: fix equipment or wires.
2) EVA foam sealing tape:
Can be used for industrial sealing: such as sealing of doors, windows, and cabinets.
Automotive industry: used for sealing and shock absorption of car doors and hoods.
Outdoor products: such as fixing tents and parasols.
3. Advantages and disadvantages
1) PE foam sealing tape:
Advantages: low cost, light weight, and easy processing.
Disadvantages: relatively poor temperature resistance and chemical resistance.
2) EVA foam sealing tape:
Advantages: excellent temperature resistance and chemical resistance, good elasticity.
Disadvantages: high cost and high density.
4. Selection suggestions
1) Choose PE foam sealing tape: if the budget is limited and the application environment does not require high temperature resistance and chemical resistance.
2) Choose EVA foam sealing tape: if higher temperature resistance, chemical resistance and elasticity are required, it is suitable for high-demand scenarios such as industry or automobiles.

Choosing the right material for your specific needs can ensure optimal performance and service life of the sealing tape.
