Rubber strips are essential sealing and insulating components used in construction, automotive, and industrial applications. Among the most popular types are EPDM rubber strips and PVC rubber strips, each offering distinct advantages depending on the use case.
Abrasion-resistant Weather-resistant Eco-friendly PVC Rubber Strip
What is EPDM Rubber Strip?
EPDM (Ethylene Propylene Diene Monomer) rubber strips are widely used due to their excellent weather resistance, durability, and flexibility. They are particularly suited for outdoor applications where exposure to UV rays, extreme temperatures, and moisture is a concern.
Key Features of EPDM Rubber Strips:
Temperature Resistance: -50°C to +150°C
UV & Ozone Resistance: Excellent
Chemical Resistance: Good against acids, alkalis, and polar solvents
Water Resistance: Highly waterproof
Elongation & Tensile Strength: 300-600% elongation, 10-20 MPa tensile strength
Common Applications: Window and door seals, automotive weatherstripping, roofing seals, and HVAC systems.
What is PVC Rubber Strip?
PVC (Polyvinyl Chloride) rubber strips are another popular sealing solution, known for their cost-effectiveness and versatility. While not as resilient as EPDM in extreme conditions, PVC strips are widely used in indoor and low-stress environments.
Key Features of PVC Rubber Strips:
Temperature Resistance: -20°C to +70°C
UV & Ozone Resistance: Moderate (may degrade over time)
Chemical Resistance: Good against oils and non-polar solvents
Water Resistance: Good, but not as durable as EPDM
Elongation & Tensile Strength: 200-400% elongation, 10-15 MPa tensile strength
Common Applications: Cabinet seals, electrical insulation, and low-cost weatherproofing.
EPDM vs. PVC Rubber Strips: Key Comparison
| Property | EPDM Rubber Strip | PVC Rubber Strip |
|---|---|---|
| Temperature Range | -50°C to +150°C | -20°C to +70°C |
| UV Resistance | Excellent | Moderate |
| Ozone Resistance | Excellent | Fair |
| Chemical Resistance | Good (acids, alkalis) | Good (oils, fuels) |
| Water Resistance | Excellent | Good |
| Durability | Long-lasting | Moderate lifespan |
| Cost | Higher | Lower |
Which One Should You Choose?
For outdoor, high-temperature, or harsh environments → EPDM rubber strip is the best choice due to its superior weather resistance.
For indoor, budget-friendly, or short-term applications → PVC rubber strip is a cost-effective alternative.
