“Battery insulation” is not one interchangeable product. Pack wrapping, cell-terminal barriers, high-temperature masking and mechanical reinforcement require different materials. A useful RFQ names the exact location, failure mode and evidence required for approval.

01 / NanXing sourcing paths

Four public Alibaba.com product links.

Verification status, 12 August 2026: the four URLs were checked as source references, but their live listing fields were not successfully retrieved. Material grade, thickness, size, temperature rating, adhesive, dielectric performance, MOQ, sample policy, customization, price and lead time are therefore not stated as verified facts on this page. Confirm all current fields on Alibaba.com or with Alma Han.

02 / RFQ fields

Connect each material to a pack function.

01Location and function

State whether the part wraps the pack, isolates a terminal, lines an enclosure, masks a process area or reinforces an assembly.

02Material identity

Name the required base material, adhesive system and color. Do not substitute product-family names for a controlled specification.

03Dimensions

Give thickness, width or flat width, length, die-cut geometry, hole location and critical tolerances on a revision-controlled drawing.

04Operating conditions

State continuous and short-term temperature, voltage environment, humidity, abrasion, chemical exposure and expected service life.

05Evidence and samples

List dielectric, flame, material-composition, adhesion or aging evidence required, then define an approved-sample and incoming-inspection plan.

06Commercial scope

Separate prototype and production quantities. Add destination, packaging limits, target date and documents required for import.

03 / Selection logic

A product name is only the start.

  1. PVC heat-shrink tubing.Confirm supplied flat width, recovered dimensions, wall thickness, shrink window, color and pack-wrapping process.
  2. Fish or barley paper.Confirm base material, thickness, adhesive construction, die-cut geometry and placement at the cell or pack barrier.
  3. Polyimide film tape.Confirm film and adhesive, total thickness, temperature exposure, peel behavior and residue acceptance.
  4. Filament tape.Confirm reinforcement direction, backing, adhesive, tensile requirement, width and packaging/assembly use.

Do not infer flammability, dielectric strength or temperature performance from color or generic material name. Validate the ordered construction and complete battery pack under intended electrical, thermal and mechanical conditions.

04 / Iraq transaction checks

Document the parties, route and final use.

For an Iraq-bound RFQ, identify the buyer, beneficial owner, consignee, freight route, payment parties, final user and civilian end use. Check applicable sanctions and export controls for the exact parties, goods and transaction before shipment. Escalate military, drone, surveillance, aerospace, restricted-industry or unclear end-use indicators for specialist review.

NanXing does not support false declarations, concealed consignees, hidden end users or sanctions and export-control evasion. This page is general sourcing information and not legal advice.

05 / FAQ

Questions to close before purchase.

What should a battery insulation RFQ include?+

Identify the exact pack location, material type, thickness, dimensions, adhesive system, temperature range, dielectric or flame requirement, drawing, quantity, sample plan, destination and required test evidence.

Are PVC tubing, fish paper and polyimide tape interchangeable?+

No. They serve different mechanical, electrical, thermal and assembly functions. The pack designer must select and validate each material for its exact location and operating conditions.

How should certificates and reports be confirmed?+

Confirm the report holder, document number, validity, tested material or product, standard, sample description and whether it covers the exact ordered specification.
