Why ShieldTex

Built for Reliable Sourcing

ShieldTex Materials is an independent sourcing partner based in China, specializing in EMI shielding and functional materials. With more than 10 years of industry experience, we help customers compare options and source stable, application-ready materials at competitive cost.

Stable Supply

We coordinate production across qualified partner plants in China, with safety stock on core items to support both small-batch trials and volume orders with reliable lead times.

Consistent Quality

Our partner plants operate full-chain quality control from incoming materials to outbound goods. Products are RoHS and REACH compliant, with SGS test reports available upon request.

Competitive Cost

Transparent quotes with no hidden fees, plus tiered discounts on order volume. Full-chain cost control keeps pricing competitive.

Fast Response

We reply within 2 hours on business days, with urgent support available on non-business days — your project timeline is never affected.

Custom Die-Cutting

We coordinate slitting, die-cutting and custom-shape converting at our partner plants — from sample and small-batch trials through to volume production.

Technical Support

We help you select the right material for your application — comparing conductive fabrics, foams, foils, films, absorbers and thermal materials for cost, performance and lead time.

Who We Are

An Independent Sourcing Partner, Run by One Person Who Knows the Industry

ShieldTex Materials is run by Eric Jiang — 10+ years in EMI shielding and functional materials, from conductive fabrics to thermal management. No account managers, no middlemen: you deal directly with the person who sources, verifies and ships your material.

That independence is the point. We're not tied to any single factory, so we source across a vetted network of partner plants and price each project on its merits — typically 20-30% below U.S. or European manufacturing.

Professional, flexible, and priced for your volume — that's what a decade of experience buys you.

What working with us means in practice:

  • One point of contact from RFQ to delivery — no runaround
  • Small MOQs and custom slitting / die-cutting to your spec
  • Free samples of stocked materials — test before you commit
  • Datasheets plus batch inspection reports with every shipment
  • We pick the best factory in our network for your project — not the only one we have

Product Portfolio

Eight Material Families, One Reliable Source

Conductive fabrics, foams, thermal materials, absorbers and films are our core lines — quoted by part number, with copper/aluminum foil tape and acetate cloth tape available on request. Conductive fabric is supplied in three constructions — plain-weave Cu-Ni (standard), conductive non-woven and gold-plated. Films run as two separate families. CC — battery current collectors: composite copper foil and composite aluminum foil, supplied in the current-collector grades the cell design calls for. FM — EMI shielding films: PET copper-plated film, PET aluminum-plated film, PI tin-plated film and PI gold-plated film. All specs are typical — final specifications confirmed per your application and applicable test standard.

Free samples available for stocked materials — test before you commit.

Need it die-cut, slit or laminated?

Every part number above is also supplied as a converted part — slit rolls, die-cut shapes, adhesive-backed and laminated constructions, cut to your drawing. Send a drawing or a target tolerance and we will quote the finished part, not just the material.

How to read a ShieldTex part number

STM – {Family} – {Spec} – {Material} – {Adhesive}

Example: STM-TIM-PAD-2.0-30 = Thermal Interface Material, pad, 2.0 mm thick, 3.0 W/m·K.

The last segment is written only when the product carries adhesive: S = single-sided, SC = single-sided conductive adhesive.

Conductive fabric and film constructions are read in the material segment: CN = plain-weave Cu-Ni, NW = conductive non-woven, AU = gold-plated, PET = PET base film, PI = polyimide base film.
