The differences and applications of different aluminum foil tapes
Different aluminum foil tapes can be classified into multiple categories based on their material structure, functional characteristics, and application scenarios. The following is a detailed analysis of the main types, their differences, and application scenarios:
1、 Classified by Material and Structure
Conventional lined/unlined aluminum foil tape
◉ Structure: Using pure aluminum foil as the substrate (thickness 0.025-0.085mm), coated with pressure-sensitive adhesive (acrylic adhesive), directly rolled without backing paper, and protected with silicone isolation paper for backing paper.
◉ Characteristics: Strong viscosity, temperature resistance (-10 ℃~120 ℃), good insulation, and electromagnetic shielding function (such as single or double conductor type).
◉ Application:
Electronic products: internal electromagnetic shielding for mobile phones, computer transformers, LCD displays, etc.
Home appliances: Oven, microwave oven seam sealing, refrigerator/air conditioning pipeline insulation repair.
Ribbed aluminum foil tape (single/double-sided) - FSK aluminum Tape
◉ Structure: Glass fiber yarn reinforcement is sandwiched between aluminum foil and kraft paper, with a composite layered design.
◉ Features: High tensile strength, waterproof, anti mold, thermal insulation, and better mechanical protection than pure aluminum foil.
◉ Application:
Building pipelines: Protection outside the insulation layer of central air conditioning and HVAC pipelines.
Large facilities: hotels, factory buildings with sealed insulation layers.
Fiberglass cloth aluminum foil tape - Reinforced Aluminum foil Adhesive tape
◉ Structure: Aluminum foil and glass fiber cloth composite, with a flame-retardant or high-temperature resistant adhesive layer.
◉ Features: puncture resistance, strong tensile strength, flame retardant (glass fiber layer self extinguishes upon release), temperature resistance up to 200 ℃.
◉ Application:
Industrial equipment: bundling of high-temperature transformers and fixing of ceramic heaters.
Pipeline engineering: steam conduit wrapping, petrochemical pipeline anti-corrosion sealing.
Flame retardant aluminum foil tape
◉ Structure: Pure aluminum foil substrate+flame retardant adhesive+silicone insulation paper.
◉ Characteristics: Oxygen index>30 (high flame retardant grade), high peel strength, good weather resistance.
◉ Application:
Security protection scenarios: car/train compartment insulation layer, steel structure building fire sealing.
Black lacquer aluminum foil tape
◉ Structure: The aluminum foil surface is coated with a black matte layer, and the substrate contains sound-absorbing material.
◉ Features: Light absorption, sound absorption, anti glare, with both anti-corrosion and flame-retardant functions.
◉ Application:
Acoustic engineering: Sound insulation and wrapping of ventilation ducts in concert halls and subway stations.
2、 Classified by functional characteristics
Conductive aluminum foil tape
◉ Single conductive type: only the aluminum foil surface conducts electricity, with adhesive insulation on the back; Used for local electromagnetic shielding (such as circuit board grounding).
◉ Dual conductivity type: Both aluminum foil and adhesive layer are conductive; Scenarios that require comprehensive conductivity, such as interlayer shielding in transformers.
◉ Application: EMI protection for computer motherboards and communication cables.
Special tape for insulation/thermal insulation
◉ Like gold aluminum foil wrapping tape (0.2mm thick) with high surface reflectivity (>85%), used for insulation wrapping of automotive intake pipes and air conditioning pipes to reduce heat radiation.
Butyl aluminum foil tape
◉ Aluminum foil+butyl rubber layer, resistant to high and low temperatures (-30 ℃~100 ℃), with strong waterproof and sealing properties.
◉ Application: Waterproof treatment for roof cracks and color steel tile joints.
3、 Choose Suggestions
◉ Electromagnetic shielding requirements ->Select conductive aluminum foil tape (single/double conductive according to grounding requirements).
◉ Thermal insulation scenario → Reinforced aluminum foil (building pipeline) or fiberglass cloth aluminum foil (industrial high temperature).
◉ Flame retardant safety requirements → Flame retardant aluminum foil tape (carriage, steel structure).
◉ Special environment (high mechanical stress, corrosion) → Fiberglass cloth aluminum foil or butyl aluminum foil tape.
