AT870 Soft Cellular Silicone Foam Die-cut Gasket

Description

AT870 Soft Cellular Silicone Foam Die-cut Gasket is designed for sealing, cushioning, shock protection, and vibration isolation in demanding electronic, automotive, appliance, and outdoor equipment applications. Made from soft cellular silicone foam with single-sided acrylic pressure-sensitive adhesive, it provides good compressibility, memory, low stress relaxation, and reliable environmental protection. The soft foam structure helps seal uneven gaps with lower closure force while maintaining long-term gasket performance. AxisTape can supply AT870 in rolls, sheets, strips, or precision die-cut parts according to customer CAD drawings, samples, or assembly requirements.

Key Features

• Soft Cellular Silicone Foam: The soft foam structure provides excellent conformability, helping the gasket fill uneven gaps and maintain sealing contact with lower compression force.
• Good Compression Recovery: The material offers good memory and low stress relaxation, helping reduce gasket failure caused by compression set, softening, or long-term deformation.
• Heat and Environmental Resistance: Cellular silicone foam provides stable performance under demanding temperature, UV, ozone, and outdoor exposure conditions.
• Shock and Vibration Isolation: The foam structure helps absorb impact, reduce vibration, and protect electronic or mechanical components during operation.
• Single-sided Acrylic Adhesive: The pressure-sensitive adhesive backing allows easier positioning, mounting, and assembly on housings, panels, enclosures, and equipment surfaces.
• Precision Die-cut Processing: AxisTape can process the material into custom gasket shapes, strips, holes, frames, pads, and sealing profiles based on CAD drawings or customer samples.

Applications

• Outdoor Equipment Sealing: Used for sealing outdoor enclosures, lighting housings, HVAC equipment, and electrical control cabinets against dust, moisture, and environmental exposure.
• Electronic Component Protection: Suitable for protecting electronic equipment from shock, heat, vibration, and gap-related mechanical stress.
• Automotive and New Energy Vehicle Applications: Applied in automotive components, sealing strips, vibration isolation pads, and new energy vehicle battery sealing areas.
• Home Appliance Assembly: Used in refrigerators, air conditioners, appliance panels, and other equipment requiring soft sealing or cushioning materials.
• Cushion Pads and Gaskets: Suitable for custom foam pads, sealing gaskets, vibration isolation parts, and protective die-cut components.
