DBDPE Particles

In the industry trend of upgrading towards dust-free, highly automated, and low loss flame retardant processing of polymer materials, the DBDPE particles produced by Taixing have completely solved the pain points of traditional powder DBDPE dust pollution, uneven dispersion, and equipment wear through innovative melting granulation and surface coating processes. This granular flame retardant without polybrominated diphenyl ether (PBDE) structure combines ultra-high bromine content and excellent thermal stability. It has no toxic dioxin release standard during thermal decomposition, providing a flame retardant solution that combines processing convenience and performance stability for industries such as electronics, new energy vehicles, and building materials.

Core strengths

1. Dust free particle design, suitable for automated processing scenarios

-Adopting the twin-screw melt extrusion granulation process, uniform cylindrical particles with a particle size of 2-3mm are produced, reducing powder dust by 99%, completely eliminating workshop pollution and operator health hazards caused by powder flying, and complying with OSHA occupational health and safety standards.

-The particle packing density is increased to 0.8-1.0g/cm ³, with excellent flowability (angle of repose ≤ 25 °). It can be directly fed through automated metering and conveying equipment without the need for additional dispersants, greatly reducing manual feeding intensity and material loss.

-The surface is coated and modified with polyethylene wax (PE wax), which increases the compatibility with polymer matrices such as PP, PE, ABS by 50%. There is no wall sticking or bridging phenomenon during the twin-screw extrusion process, and the equipment cleaning cycle is extended by three times, reducing downtime for maintenance.

2. Ultra high flame retardant efficiency

-Bromine content ≥ 82.5%, unit mass flame retardant efficiency is equivalent to powder DBDPE. It quickly captures combustion free radicals in the gas phase to interrupt chain reactions, promotes the formation of a dense carbon layer on the substrate in the condensed phase to block oxygen and heat transfer, and has a dual effect on suppressing flame spread.

-The 1% thermal weight loss temperature is ≥ 325 ℃, the maximum decomposition temperature is ≥ 420 ℃, and the processing temperature window is wide up to 190-245 ℃. It is suitable for various processes such as extrusion, injection molding, and compression molding. Even in high-temperature engineering plastic processing environments such as nylon and PBT, there are no decomposition, yellowing, or gas release problems.

-Excellent synergistic effect with antimony trioxide and zinc borate, when combined with 3% -5% antimony trioxide, can easily achieve UL 94 V-0 flame retardant standards for 1.6mm thick PP and ABS substrates, reducing the addition amount by 10% -15% compared to traditional powder DBDPE.

3. Low performance loss, ensuring the mechanical and appearance quality of the product

-The granular form avoids the problem of uneven flame retardant performance caused by powder agglomeration, and the surface of the product has no defects such as white spots or pockmarks. The glossiness is increased by 20%, especially suitable for scenes with strict appearance requirements such as household appliance shells and automotive interior parts.

-The impact on the mechanical properties of the substrate is extremely low. Under the same flame retardant requirements, the retention rate of tensile strength is ≥ 94%, and the retention rate of impact toughness is ≥ 93%, fully meeting the dual requirements of strength and toughness for structural components.

-Widely adaptable to material systems such as general plastics, engineering plastics, rubber, etc., without the need to adjust existing processing equipment parameters, it can directly replace powder DBDPE and be put into production.

Frequently Asked Questions

Q1: Will the carrier in the granular product affect the performance of my final product?

A1: The carrier has been carefully selected and has high compatibility with your target matrix resin or is already a similar resin. The addition amount is precisely calculated to ensure that the impact on the mechanical, thermal, and electrical properties of the final product is minimized while achieving the flame retardant goal, and even to produce positive effects by optimizing the interface interaction.

Q2: What is the cost-effectiveness of particle morphology compared to using powder?

A2: It needs to be considered from a comprehensive cost perspective. Although the unit price of particles may be slightly higher, they can often achieve a return on investment (ROI) in the short term by eliminating dust waste (up to 2-5%), reducing pre-treatment energy consumption, lowering cleaning and maintenance costs, improving production rate and product yield. More importantly, the improvement in quality consistency and environmental compliance and safety it brings is an intangible and enormous value.
