  • Q Can I order custom widths or lengths?

    A Yes. We offer custom widths, thicknesses, and roll lengths to fit your process. Contact our sales team with your specifications and required quantity.
  • Q How should I store and handle the tape?

    A Store in a cool, dry place away from direct sunlight and heat sources. Avoid prolonged exposure to moisture. Keep the roll in its original packaging when not in use.
  • Q What is the typical lead time?

    A Standard products ship within 7 business days after order confirmation; custom options may take longer. We’ll confirm a firm lead time with you at order.
  • Q Is the adhesive silicone-based, acrylic, silicone-acetate?

    A The adhesive is silicone-based, however, customer can customize acrylic-based tape, which provides higher adhesion.
  • Q What is the difference between PTFE silicone adhesive tape and PTFE acrylic tape?

    A
    Temperature performance
     
    ● Silicone adhesive:
    Excellent high-temperature stability and remains flexible at low temperatures;   suitable for thermal cycling and gaskets/seals.
     
    ● Acrylic adhesive:
    Good overall temperature performance but generally not as flexible as silicone;   may become more brittle at very low temperatures or soften at high temperatures.
     
    Chemical resistance and environment
     
    ● Silicone adhesive:
    Excellent resistance to moisture, water immersion, UV exposure (for outdoor use), and many chemicals;   maintains elasticity.
     
    ● Acrylic adhesive:
    Good chemical and UV resistance for many environments but typically less flexible than silicone;   weathering resistance is formulation-dependent.
     
     
    Flexibility vs rigidity
     
    ● Silicone adhesive on PTFE:
    More flexible, able to accommodate movement, vibration, and thermal expansion without losing seal.
     
    ● Acrylic adhesive on PTFE:
    Typically stiffer;   strong initial hold but less forgiving with movement;   better for rigid, high-tack bonds.

  • [PTFE Adhesive Tape] PTFE Tape Salt Spray Resistance & Marine Application Requirements
    PTFE high-temperature tape has excellent salt spray resistance, but the weak points are the adhesive layer and the fiberglass substrate edges. Evaluation methods: 1000h neutral salt spray (NSS) test, measuring peel strength retention (≥80% required), visual defects (lifting, blistering), and metal substrate corrosion. For marine and high-salt-fog environments: use silicone PSA (not acrylic), fully impregnated PTFE substrate, seal edges with weather-resistant sealant, and apply primer on metal surfaces.
  • [PTFE Adhesive Tape] PTFE Tape Reusability: How to Improve Repeated Adhesion Performance
    PTFE high-temperature tape loses adhesion after repeated use due to surface contamination (dust, silicone oil), adhesive cohesive failure (residue), or weak substrate bonding. Solutions: high-crosslink silicone PSA (low migration, balanced tack/holding power), primer treatment on the PTFE substrate, dense fiberglass backing, and proper handling (clean surfaces, cool peel, 180° angle). Quantitative testing validates improvement.
  • [PTFE Adhesive Tape] PTFE Tape Shelf Life: What You Need To Know for Proper Storage
    PTFE high-temperature tape stored under specified conditions (10-25°C, 40-70% RH, away from UV/heavy pressure) has a standard shelf life of 3-6 months (premium grades up to 12 months). Key degradation thresholds: peel strength must not drop below 70% of initial value; no adhesive residue after high-temperature removal; no carbonization or cracking at rated temperature. Quick checks: manual unwinding feel, 260°C residue test, and lamination shrinkage test.
  • [PTFE Adhesive Tape] How To Stop Rolled PTFE Tape From Sticking To Itself During Long-Term Storage
    Rolled PTFE tape can develop interlayer adhesion (blocking) and adhesive transfer during long-term storage. Causes: PTFE film elastic memory and silicone PSA creep under pressure/heat. Prevention: gradient winding tension (outer tight, inner loose) during manufacturing, plus release coating on the non-adhesive side. Store at -15°C to 40°C, 30-70% RH, horizontally on racks, rotate rolls quarterly. For thick adhesive grades, add release paper between layers.
  • [PTFE Adhesive Tape] Stop PTFE Tape Layers From Sticking During Storage: Gradient Winding Tension Design
    PTFE high-temperature tapes stored in roll form can suffer from interlayer adhesion (blocking) and adhesive transfer to the non-stick side. Root causes: PTFE film elastic memory and silicone PSA creep under pressure and heat. Solution: gradient winding tension – tight on outer layers, loose on inner layers – using closed-loop tension control. Complement with release coating, proper storage (15-40°C, 30-70% RH), horizontal placement, and quarterly roll rotation.
