who we are?
SUNTEX is a manufacturer and international supplier of coated fiberglass fabrics and other high-temperature technical textile materials used in industrial heat, fire and safety applications. The company was established in 2004, when coated fiberglass materials made in China were still limited in product range and often varied in consistency. Its founders, drawing on long experience in fiberglass and high-temperature materials, set out to build a business based on product development, controlled manufacturing and repeatable quality rather than price alone.
Today, SUNTEX develops and manufactures silicone-, polyurethane- and acrylic-coated fiberglass fabrics, as well as graphite- and vermiculite-treated fabrics, aluminum-foil and film-laminated materials, high-silica textiles, welding blankets, fire blankets and related fabricated products. These materials are supplied to manufacturers of removable insulation jackets, fabric expansion joints, flexible connectors, smoke and fire curtains, fabric air ducts, welding protection products and other industrial thermal-protection components.
The work begins with the conditions in which a material will be processed and used. Temperature exposure, flame behavior, flexibility, abrasion, coating adhesion, dimensional stability and cutting or sewing requirements can all affect the suitability of a specification. This application-based understanding allows standard materials to be selected where appropriate and custom specifications to be developed when an application requires a different combination of substrate, coating, weight, thickness, width or surface treatment.
SUNTEX operates its own manufacturing, product-development and inspection functions. Customer requirements are translated into product codes, specifications and production instructions so that an approved material can be reproduced for later orders. Raw-material control, production records, in-process checks and final inspection support consistent delivery across batches. Sales, technical, quality and contract-delivery staff work within the same operating process, which helps keep technical requirements, documentation and shipment arrangements aligned from enquiry through delivery.
The company has an annual production capacity of 8 million meters and has supplied more than 500 industrial customers across over 70 countries and markets. Its customers operate in industrial insulation, energy, petrochemical processing, marine and shipbuilding, power generation, ventilation, transportation, fire protection and occupational safety. Across these sectors, SUNTEX's role remains focused: to provide stable material specifications, practical development support and reliable international supply for manufacturers whose finished products depend on heat and fire performance.

Why Customers Work with SUNTEX
A practical view of the production control, specification management and technical support behind a reliable material supply.
What a factory manager needs to confirm
Can the supplier make the same specification repeatedly? Are production and inspection under control? Can orders be delivered as agreed, and will problems be handled clearly? SUNTEX has built its manufacturing system around these practical requirements.

1# Understand Application
Clarify operating conditions and priorities
Evidence: Application review or technical requirement record
The approved specification is carried into production
Once a material is approved, SUNTEX assigns a product code and records its construction, coating system, key requirements and inspection criteria. This gives production and quality teams a clear standard for repeat orders.
VERIFY ON SITE | Product code • Approved specification • Repeat-order record


Quality is checked during the process
Under its ISO 9001 quality management system, SUNTEX checks incoming materials, coating preparation, in-process production and finished fabric. Batch records and test results are retained for traceability and variation is reviewed before shipment.
VERIFY ON SITE | Incoming → In-process → Finished fabric → Batch record
Material selection starts with the actual use
The technical team reviews working temperature, flexibility, mechanical performance, fabrication method and relevant testing needs before recommending an existing material or developing a custom specification. This helps avoid repeated trials and unsuitable choices.
APPLICATIONS | Insulation jackets • Expansion joints • Welding • Fire curtains


Orders and problems have clear ownership
Production, quality, technical and export teams work from the same confirmed order requirements. If a specification, test, delivery or quality issue arises, the relevant team reviews the records, communicates the cause and follows the corrective action.
CLEAR RESPONSIBILITY | Order confirmation • Record review • Corrective action

Principles Applied to Our Work
Integrity — We communicate material capabilities, test results, lead times and limitations accurately. Commitments are made on a realistic basis, and problems are addressed openly.
Customer Focus — We begin with the customer’s application, processing conditions and performance priorities. The objective is to identify a suitable standard product or develop a practical custom specification—not simply to offer what is already available.
Excellence — We work to maintain specification and batch consistency through process control, inspection and continual improvement. Quality is measured by whether the material performs reliably in the customer’s production and end use.
Creativity — When an existing material does not fully meet the requirement, our technical and production teams examine alternative fibers, coatings, constructions and processing methods, then convert workable solutions into repeatable specifications.
Accountability — Responsibility continues from requirement review and sampling through production, shipment and after-sales support. When an issue occurs, the relevant team follows it through to cause analysis, corrective action and feedback.
Our Commitment
SUNTEX aims to provide business partners with the appropriate material, consistent specifications, reliable delivery and responsive technical support. We define value as helping customers reduce material-related risk, maintain stable production and build products they can supply with confidence—not simply offering the lowest initial price.
Mission and Vision
Our mission is to develop reliable high-temperature textile materials that help customers manage heat, reduce fire risk and improve the safety and durability of industrial products.
Our vision is to build SUNTEX as a trusted Chinese brand in the global high-temperature technical textile industry, recognized for professional materials, responsible manufacturing and dependable long-term supply.
