Silicone contamination control
The urethane formulation avoids intentional silicone gel at the terminal seal interface.
This reverse-gel profile uses a silicone-free urethane fill and places the trough on the downstream side of an anodized aluminum frame. It is intended for supported ePTFE HEPA or ULPA filters in semiconductor environments where silicone contribution is restricted. The channel preserves the positive knife-edge sealing principle while separating the design from conventional silicone-gel terminals; all adjacent sealants and handling materials must follow the same contamination-control requirement.
The urethane formulation avoids intentional silicone gel at the terminal seal interface.
The trough orientation supports semiconductor ceiling and mini-environment knife-edge arrangements.
The frame configuration is suited to supported, boron-free ePTFE media packs.
