Shown here are some of the other characteristics or needs to consider and verify in the application. System applications are different and hence, needs and considerations can extend this list. Tack or adhesion is important if structural support or ease of rework are required. Durability refers to the high puncture, shear, tear resistance might be required (choose between support or without support of fiberglass). Silicone free Gap Pads offer an important factor for applications requiring low volatility or outgassing. Bergquist tests in accordance with industry standard ASTM E595 to ensure outgassing standards are meet. Other factors include ease of usage for manufacturing, regulatory standards, and shelf life. Customers are always encouraged to test each design within the application to verify compliance to expected system requirements.
