Essential Technical Properties and Trade Terminology for rubber strip door seal
Key Technical Properties to Evaluate
1. Material Grade and Compound
The composition of a rubber strip door seal directly influences its resistance to specific environments. Common grades include EPDM (for UV/ozone resistance), neoprene (chemical and weather resistance), and silicone (wide temperature tolerances and food safety compliance). For international B2B buyers—from humid African climates to cold European zones—selecting the correct grade ensures performance longevity, regulatory compliance, and reduced maintenance costs.
2. Hardness (Durometer, Shore A)
Expressed as a number on the Shore A scale (e.g., 40A, 70A), durometer indicates the hardness or softness of the rubber. Softer strips (lower durometer) seal better around uneven surfaces, while harder compounds provide better durability for high-traffic or industrial doorways. Specifying the appropriate durometer is crucial for balancing compression, resilience, and the door’s sealing effectiveness in your target market.
3. Tolerance (Dimensional Accuracy)
Tolerance refers to the permissible deviation in the dimensions (width, thickness, profile) of the strip. For door seals, even small variations can impact sealing performance—causing leaks, drafts, or installation issues. International buyers should request detailed tolerance data according to ISO or DIN standards and ensure suppliers adhere to agreed tolerances, especially when sourcing for large-scale or critical projects.
4. Temperature Resistance
A seal’s operating temperature range determines suitability for specific climates and industrial processes. EPDM typically operates from -40°C to +120°C, while silicone may withstand -60°C to +200°C. Factors like direct sun, cold storage, or proximity to machinery should dictate your minimum and maximum temperature requirements. Assess test certifications if your usage involves temperature extremes found in regions like the Middle East or Northern Europe.
5. Compression Set
This metric refers to a material’s ability to return to its original shape after being compressed—a key factor for maintaining a consistent, long-term seal. A low compression set value is desirable, indicating the strip won’t easily flatten out or lose effectiveness over time, even after repeated door cycles or pressure fluctuations.
6. Flame and Chemical Resistance
For some sectors and jurisdictions, especially in public buildings or industrial facilities, compliance with fire-retardant standards (e.g., UL94, DIN 4102) or chemical resistance requirements is mandatory. Buyers should verify certifications and seek clarification on the exact exposure levels and substances involved, as these properties determine suitability in applications such as hospitals, food processing, or heavy industry.
