For inquiries or to place an order, please contact us.

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 ] What are the differences in the effects of infrared radiation heating versus hot-air circulation heating on the uniformity of the crosslinked structure of the silicone adhesive layer?

This article compares differences between infrared radiation heating and hot-air circulation heating on crosslinked structure uniformity of silicone adhesive layer. Heat transfer mechanisms: hot-air is convection-conduction, gentle and progressive, creating moderate temperature gradient; IR is radiation-absorption with intense surface absorption (micrometers to millimeters) creating steep surface-to-interior gradient. Effects on crosslink density distribution: hot-air allows inner and outer portions to enter vulcanization temperature range nearly simultaneously, yielding uniform crosslink density along thickness; IR causes surface layer to cure instantly forming dense skin that hinders heat transfer, resulting in sharp gradient of crosslink density decreasing from surface inward.
[PTFE Adhesive Tape ] What are the effects of web tension control during the coating process of Teflon high-temperature tape on the flatness of the PTFE substrate and the uniformity of the adhesive coating?

This article examines effects of web tension control during Teflon high-temperature tape coating on PTFE substrate flatness and adhesive coating uniformity. Effects on substrate flatness: tension exceeding elastic limit causes irreversible plastic stretching and necking (longitudinal elongation, transverse narrowing), forming slackness, wrinkles and wavy patterns; PTFE creep under sustained tension becomes "frozen" after cooling, causing surface unevenness; uneven transverse tension from poor roller parallelism creates curled edges, central blistering, and periodic tight-loose marks.
[PTFE Adhesive Tape ] The pattern of change in the cohesive strength of the adhesive layer of Teflon high-temperature tape after high-temperature aging.

This article describes the pattern of change in cohesive strength of PTFE high-temperature tape adhesive layer after high-temperature aging. Three-stage pattern: Post-curing rising stage (early high-temperature exposure at 200-260°C, residual reactive groups continue crosslinking, cohesion significantly increases); Stable equilibrium stage (crosslinking approaches completion, cohesion remains stable over long periods); Degradation and decline stage (excessive time/temperature causes main chain degradation, cohesion decreases, adhesive softens and becomes tacky). Root causes of cohesive failure (internal tearing leaving residue) and squeeze-out (cold flow from edges due to decreased modulus) are analyzed.
[PTFE Adhesive Tape ] How can the creep resistance and long-term holding stability of high-hold Teflon high-temperature tape be improved?

This article presents methods to improve creep resistance and long-term holding stability of high-hold Teflon high-temperature tape. Strategies include: Molecular network topology optimization — high MQ silicone resin/gum ratio (1.2:1–2:1) forms rigid hard-phase domains; incorporation of phenyl groups (20-30 mol%) hinders chain motion; crosslink molecular weight controlled at 5,000-15,000 g/mol; Gradient modulus multilayer adhesive structure — primer-anchoring layer (1-3μm) with silane coupling agent, high-modulus cohesive layer (30-50μm) as shear-resistant skeleton, viscoelastic functional layer (3-8μm) for surface wetting; Nanofillers — fumed silica (10-25 wt%) with surface modification creates reversible physical crosslinking.
[PTFE Adhesive Tape ] How can the microporous structure design of breathable Teflon high-temperature tape balance air permeability with insulation and non-stick properties?

This article addresses how microporous structure design of breathable Teflon (PTFE) high-temperature tape balances air permeability with insulation and non-stick properties. Core conflict: air permeability requires open pores, while insulation demands density and non-stick requires smooth surfaces. Balanced design strategies: control average pore diameter (0.1-2μm, ideally <0.5μm) to prevent melt penetration and maintain breakdown voltage; control porosity at 50-70% (≈60% optimal) achieving Gurley 20-100s/100cc and dielectric strength ≥2kV for 0.13mm film; adopt high-tortuosity 3D network pore structure (τ≈2.5-4) to suppress straight-through discharge channels; construct asymmetric gradient pore structure with dense surface skin layer (1-5μm) for non-stick/insulation and porous interior for breathability; apply super-oleophobic/hydrophobic surface post-treatment without pore blockage.
