High-temperature tape

High-temperature tape for the thermal spraying industry is a critical auxiliary material in the thermal spraying process, specifically developed to meet the shielding and protection needs of workpieces during plasma spraying, high-velocity oxy-fuel (HVOF) spraying, arc spraying, and other high-temperature coating processes. Its core function is to precisely shield key areas of workpieces (such as threaded holes, sealing surfaces, precision mating surfaces, and non-coating areas) from high-temperature spray particles, preventing coating adhesion and damage to precision structures. At the same time, it can resist high-temperature radiation and thermal shock during spraying, avoiding tape decomposition, carbonization, or adhesive residue that may contaminate the coating or substrate.
  • Detail
  • Parameters

The product system covers a full range of high-performance models tailored to different temperature grades and application scenarios, including silicone-based high-temperature tape, polyimide (Kapton) high-temperature tape, ceramic fiber-reinforced high-temperature tape, and aluminum foil composite high-temperature tape. Among them, silicone-based high-temperature tape can withstand continuous temperatures of 260℃ and short-term high temperatures of up to 300℃, featuring excellent flexibility and adhesion, suitable for general thermal spraying shielding; polyimide high-temperature tape has a continuous temperature resistance of 300℃ and strong chemical resistance, ideal for precision component shielding in high-precision thermal spraying processes; ceramic fiber-reinforced high-temperature tape can withstand extreme temperatures of 800–1200℃, with outstanding thermal insulation and ablation resistance, applicable to ultra-high-temperature spraying processes such as plasma arc surfacing; aluminum foil composite high-temperature tape combines the heat resistance of aluminum foil and the adhesion of special adhesives, providing both shielding and heat reflection effects, suitable for large-area workpiece shielding.

All products are manufactured with high-quality special substrates and high-temperature resistant adhesives (such as silicone pressure-sensitive adhesive, modified acrylic adhesive). The substrate is processed through special calendering and reinforcement techniques to ensure high tensile strength and tear resistance, while the adhesive layer adopts a high-temperature stable formula that maintains strong adhesion at high temperatures and leaves no residual adhesive after peeling. The core advantages include wide temperature resistance range (200℃–1200℃), precise shielding performance, strong adhesion without residue, excellent thermal shock resistance, and good compatibility with various substrates (steel, aluminum alloy, titanium alloy, ceramic, etc.). The tape is flexible and conformable, easily adhering to irregular workpiece surfaces, and can be cut into custom sizes or shapes on-site, supporting convenient construction methods such as manual pasting and mechanical winding.

Backed by professional R&D capabilities, we can provide customized high-temperature tape solutions according to customers' specific process requirements, including customizing thickness (0.08mm–0.5mm), width, length, and adhesive type, and optimizing product formulas for special working conditions such as ultra-high temperature, strong corrosion, or ultra-precision shielding. The product is widely used in aerospace component spraying, petrochemical equipment coating, rail transit part processing, mold manufacturing, wind power component spraying, and other thermal spraying fields. It effectively protects the precision structure and performance of workpieces, improves coating quality and process stability, and reduces post-spraying cleaning and repair costs.
