Dimensional Accuracy:
Silicone strips are typically extruded, with dimensional tolerances (e.g., ±0.10mm or ±0.15mm) meeting your assembly requirements. This is directly related to mould precision. Hardness (Shore A):
Common ranges span from 20°A to 80°A.
Low Hardness (Soft, 20-40°A): Excellent sealing properties, suitable for uneven surfaces. Suited to applications requiring significant compression. Medium Hardness (General Purpose, 50-60°A): Balances sealing and support properties, most commonly used.
High Hardness (Hard, 70-80°A): Provides superior support and wear resistance, though compression requires greater force. Sealing Structures:
Solid Seals: Versatile, providing uniform contact pressure.
Hollow Seals (with air chambers): Easier compression, superior rebound, and greater adaptability to irregular surfaces. Specialised Seals: Featuring lips, fins, or other unique structures for specific sealing functions (e.g., scraping, low friction).
