Guolan New Materials (Shandong) Co., Ltd. is one of the leading manufacturers and suppliers of triethyl phosphate 99.5% flame retardant in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk top-quality triethyl phosphate 99.5% flame retardant from our factory.
Product Overview
Triethyl Phosphate 99.5% flame retardant grade is a high-purity triethyl phosphate specifically optimized for flame retardant applications in engineering plastics, polymers, and coating systems. With a minimum purity of 99.5%, this grade delivers consistent and reliable flame retardant performance across diverse material platforms. Its low molecular weight enables easy incorporation into polymer matrices during melt processing, while its chemical structure provides effective flame suppression through gas-phase radical quenching mechanisms.
Unlike halogenated flame retardants, TEP is a phosphorus-based additive that operates through char-forming mechanisms in the condensed phase, producing a protective carbonaceous layer that insulates the underlying material from heat and oxygen. This mechanism provides effective flame retardancy without generating toxic halogenated fumes during combustion, making TEP an attractive option for applications with strict environmental and safety regulations.
Guolan New Materials produces TEP 99.5% flame retardant grade using advanced purification processes that minimize acidic impurities and colored by-products. Our continuous manufacturing technology ensures batch-to-batch consistency, critical for high-performance applications in electronics, automotive, and construction sectors. With 15,000 MT/year capacity, we provide reliable supply for both regular orders and large-scale projects.

Feature Highlights
- High Purity Assurance: Guaranteed 99.5% minimum content ensures consistent flame retardant performance and minimizes impact on base polymer properties such as color, transparency, and mechanical strength.
- Effective Flame Suppression: Phosphorus-based flame retardant mechanism provides excellent fire protection for thermoplastics and thermosets, reducing peak heat release rate and promoting char formation.
- Low Volatility Processing: High boiling point and low vapor pressure enable processing at elevated temperatures without significant loss, ensuring uniform flame retardant distribution throughout the product.
- Good Polymer Compatibility: Miscible with most common engineering plastics including ABS, PC, PET, PBT, and various epoxy systems, without requiring compatibilizers or coupling agents.
- Non-Halogenated Formula: As a phosphorus-based additive, TEP avoids the environmental and health concerns associated with brominated and chlorinated flame retardants, supporting compliance with increasingly stringent regulations.
- Versatile Application Range: Suitable for injection molding, extrusion, compression molding, and coating applications across automotive, electronics, construction, and consumer goods industries.
Industry Application Scenarios
Engineering Plastics Flame Retardancy
TEP 99.5% is widely used as a flame retardant in ABS, HIPS, PC/ABS blends, and other engineering thermoplastics used in electrical enclosures, connector housings, and automotive interior components. It provides effective flame suppression while maintaining the mechanical properties and surface finish required by OEM specifications.
Polyester & Epoxy Resins
In unsaturated polyester resins and epoxy systems, TEP serves as both a flame retardant and a reactive diluent, improving processability while imparting fire resistance. Applications include fiberglass-reinforced panels, marine coatings, and fire-resistant composites for construction and transportation.
Coatings & Surface Treatments
TEP 99.5% flame retardant is incorporated into industrial coatings, wood coatings, and textile treatments to achieve flame retardant compliance. Its compatibility with various resin systems ensures stable performance without cloudiness, precipitation, or viscosity issues in the final coating formulation.
Consumer Electronics & Automotive
Used in flame-retarded polymers for consumer electronics housings, cable insulation, and automotive parts where fire safety regulations mandate specific flammability ratings. TEP helps manufacturers meet UL94, V-0, and other industry standards while maintaining material aesthetics and mechanical performance.
FAQ
Q: What loading level of TEP 99.5% is typically needed for flame retardancy?
A: Loadings depend on the polymer and the target rating. TEP is miscible with ABS, PC, PET, PBT and epoxy systems without compatibilizers or coupling agents, so trials usually start from a low single-digit percentage and are adjusted against the specific flammability standard your product must pass.
Q: Does the flame retardant affect colour or transparency of the resin?
A: Because content is held at 99.5% minimum and chromaticity at 10 APHA maximum, the impact on base-polymer colour and transparency is minimized - which is why this grade is specified for housings and clear or light-coloured mouldings where yellowing would be visible.
Q: Which processing methods is this grade suitable for?
A: TEP 99.5% is used across injection molding, extrusion, compression molding and coating applications, serving automotive, electronics, construction and consumer goods manufacturers.
Q: How does the phosphorus mechanism differ from halogenated retardants?
A: TEP works through a phosphorus-based mechanism that reduces peak heat release rate and promotes char formation. As a non-halogenated additive it avoids the environmental and health concerns attached to brominated and chlorinated retardants, supporting compliance with tightening regulations.
Q: Can TEP act as a reactive diluent as well as a flame retardant?
A: In unsaturated polyester and epoxy systems TEP serves both roles at once, improving processability and viscosity while imparting fire resistance - useful where a separate diluent would otherwise dilute flame performance.
Q: What documentation supports regulatory submissions?
A: Each batch ships with a Certificate of Analysis stating content, chromaticity, acid value, moisture and density. MSDS is available on request, and TEP is listed on the TSCA inventory; REACH status for your specific EU application should be confirmed with our technical team.
Q: What packaging and order quantities apply to this grade?
A: We supply 250 kg iron drums, 500 kg plastic drums and 25,000 kg tank cars, with a minimum order quantity of 1 metric ton and annual capacity of 15,000 MT for this product line.
Why Choose Guolan New Materials
- Purity Specified For Flame Performance: A guaranteed 99.5% minimum content keeps flame retardant behaviour predictable batch to batch, so a formulation qualified once does not need re-tuning when the next drum arrives.
- Char-Forming Phosphorus Chemistry: The phosphorus mechanism reduces peak heat release and promotes char formation, addressing the two measurements that most often decide pass or fail on engineering plastic flammability tests.
- No Compatibilizer Needed: TEP is miscible with ABS, PC, PET, PBT and epoxy systems directly, which removes a formulation step and one more variable from your compounding trials.
- Halogen-Free By Design: As a phosphorus-based additive it carries no halogen, supporting RoHS and REACH-driven specifications and avoiding the regulatory pressure now falling on brominated and chlorinated retardants.
- Low Volatility Through Moulding: High boiling point and low vapour pressure allow processing at elevated temperatures without significant loss, so flame retardant stays uniformly distributed in the moulded part instead of flashing off in the barrel.
