• Wide range of hardness options

• Good compression resistance

• Susceptible to UV degradation without proper additives

Cost-Effectiveness Analysis:
PVC seals typically cost 40-60% less than EPDM alternatives, making them attractive for budget-conscious applications. However, lifespan in outdoor applications may be 3-5 years compared to EPDM’s 10-15 years. For indoor applications without UV exposure and temperature extremes, PVC provides adequate performance at minimum cost. TPE/TPV materials bridge the gap between PVC and rubber, offering better elasticity and temperature resistance at a moderate price premium over PVC.

Optimal Applications: Interior door seals, low-cost appliance applications without extreme conditions, temporary weatherproofing solutions.

Neoprene (Chloroprene) Rubber Seals

Neoprene offers a balanced profile with good all-around properties, particularly valued for “flame-resistant appliance gaskets” and “versatile rubber weatherstripping.”

• Lightweight with low material usage

• Variety of density options for specific compression requirements

• Generally lower durability than solid rubber

Cost-Effectiveness Analysis:
Foam seals offer the lowest material cost per linear foot but may require more frequent replacement in high-use applications. Their superior sealing at minimal compression force makes them ideal for applications where door/window alignment cannot be precisely controlled. For retrofit and DIY markets, foam tapes with adhesive backing provide installation savings that offset material limitations.

Optimal Applications: Irregular surface sealing, acoustic insulation, low-pressure closure applications, temporary seals.

Performance Factors and Selection Criteria

Compression Set Resistance

Compression set measures a material’s ability to return to its original thickness after prolonged compression. This critical property determines seal longevity in appliance doors that remain closed for extended periods. EPDM and silicone typically offer the best compression set resistance (15-25% set after 22 hours at 70°C), while PVC and foam materials may exhibit 40-60% set under the same conditions. For refrigerator and oven doors, materials with compression set below 30% are essential for maintaining energy efficiency throughout the product lifespan.
