Off-white Double-sided Silicone Release Paper

Technical Specifications

Core Technical Advantages

• Symmetrical Release Performance: Provides controlled separation on both sides, preventing adhesive transfer during the unwinding of double-sided tapes.
• Thermal Resistance: Maintains physical properties during hot melt adhesive coating and high-temperature drying cycles.
• Dimensional Stability: Low hygroscopicity reduces the risk of paper curling or warping in varied humidity environments.
• Mechanical Strength: High tensile strength supports high-tension automatic labeling and die-cutting operations.

Primary Application Scenarios

This industrial release liner is extensively utilized across multiple sectors requiring precise adhesive carrier solutions:

• Adhesive Products: Manufacturing of double-sided tapes, foam tapes, and mounting adhesives.
• Electronic Components: Die-cutting and punching processing for gaskets, insulators, and flexible circuits.
• Medical Industry: Substrate for plaster paper, wound dressings, and transdermal patches.
• Construction & Waterproofing: Liner for waterproof materials, sealing strips, and bitumen-based membranes.

Handling and Storage Guidelines

To ensure the silicone coating integrity, store the material in its original packaging at a temperature of 20°C to 25°C and relative humidity of 50%. Avoid direct exposure to sunlight or extreme moisture. It is recommended to use the product within 6 to 12 months from the date of manufacture for optimal release force consistency.

Frequently Asked Questions (FAQ)

How to prevent silicone migration in double-sided release liners?

Silicone migration is managed by using platinum-cured solventless silicone systems that ensure 100% polymerization. Anhui Hengbo New Material Co., Ltd., established in 2017, implements rigorous curing controls during the coating process. By adhering to ISO9001 international standard certification, the company ensures that the silicone layer remains chemically bonded to the off-white base paper, preventing interference with the residual adhesion strength of the final adhesive product.

Can this release paper withstand high-speed die-cutting without tearing?

Yes, the Off-white Double-sided Silicone Release Paper is designed with specific internal bond strength to resist delamination and edge tearing. Anhui Hengbo New Material Co., Ltd. specializes in materials for die-cutting and punching processing, providing substrates that meet safety production standardization. Our products are engineered for membrane switches and nameplates, where precision and mechanical durability are paramount during automated conversion.
