Our Company

BSTFLEX (Ningguo BST Thermal Products Co., Ltd.) is a manufacturer focused on thermal protection solutions for demanding environments. We support OEM and industrial customers with materials and engineered products designed to manage radiant heat, direct contact heat, abrasion, vibration, and fluid exposure in real-world installations.

Our product portfolio covers thermal sleeves, fire sleeves, heat shield barriers, exhaust thermal insulation solutions, and welding/hot-work protection—helping customers reduce heat transfer, protect critical components, improve reliability, and enhance workplace safety.

1) What We Manufacture

BSTFLEX supplies a broad range of thermal protection products, commonly used across automotive, industrial equipment, marine systems, power generation, rail applications, and maintenance operations.

• Fire sleeves for hoses, cables, wiring harnesses, and fluid lines
• Heat shield tapes and barrier materials for localized radiant heat control
• Exhaust heat shield insulation solutions for under-hood thermal management
• Welding protection products for hot-work safety and site shielding

2) How We Support OEM & Industrial Procurement

We understand that buyers need more than a catalog. Our support is built around repeatable production, documentation readiness, and response speed for engineering and sourcing teams.

• Product selection support: match construction to exposure (radiant heat, contact heat, flame, abrasion, fluid)
• Documentation support: CoC, inspection reports, SDS/MSDS, RoHS/REACH where applicable
• Production repeatability: lot control and traceability designed for ongoing programs
• Customization: conversion and manufacturing options for program-specific parts

To understand our inspection workflow and batch traceability, see: Quality Guarantee. For certificates and compliance documents, see: Certifications.

3) Custom Manufacturing & Conversion

Many projects require thermal protection components that fit a defined installation space or assembly process. We support custom programs through cutting, die cutting, special packing, and labeling.

4) Global Service Mindset

We work with international customers who need clear communication, stable lead times, and documentation that supports internal approvals and audits. If your project requires multi-market documentation, structured RFQ handling, or application guidance, our team can support you through selection and ordering.
