Molded silicone foam sealing gasket: Precise craftsmanship creates ultimate sealing

** Product Process ** : The ** foaming process ** is adopted.  Firstly, a uniform base foam is formed through physical foaming, and then the pores are refined to 50-150μm by chemical foaming technology, combined with high-precision molding.  After vacuum mixing, intelligent temperature-controlled vulcanization (190℃×25min), edge fine finishing and other processes, the surface is smooth without bubbles, and the cell structure is dense and uniform.

** Product Features ** :
- ** Superior sealing performance ** : Compression and rebound rate > 85%, adaptable to temperature differences ranging from -50℃ to 200℃, maintaining excellent sealing performance under a pressure of 1.5MPa, with water and dust resistance reaching IP68 level **, effectively blocking liquids, gases and dust.
- ** Excellent durability ** : Tear resistance ≥10kN/m, resistant to ozone aging (no cracks at 50pphm×40℃×72 hours), resistant to oil and chemical corrosion (resistant to gasoline, alcohol, weak acids and alkalis), and the service life is more than three times longer than that of ordinary sealing gaskets.
- ** Flexible adaptability ** : The density is adjustable from 0.3 to 1.2g/cm³.  Different hardness (10-60 Shore A), color and cross-sectional shape (D-type, P-type, rectangular, etc.) can be customized to adapt to various sealing scenarios such as doors and Windows, boxes, pipes, etc.

** Quality Service ** : Certified by international standards such as FDA, RoHS, and UL, we offer free sample testing and 3D modeling services.  We provide 72-hour rapid prototyping, support large-scale customized production, have global logistics coverage, and provide 24-hour after-sales response.

With precise craftsmanship, we create industrial-grade sealing solutions.  Molded silicone foam sealing gaskets ensure the safe operation of equipment.
