Electronic Grade Aluminum Hypophosphite

The electronic grade aluminum hypophosphite developed and produced by Taixing innovatively adopts the core technology of electronic grade raw material purification and precision grading modification. It uses high-purity Al (H ₂ PO ₂) I3 as the matrix, with a purity of over 99.8% and a phosphorus content of ≥ 42.5%. It combines efficient flame retardancy and excellent electrical performance. With only 6% -10% addition, it can achieve a 1.6mm thickness UL 94 V-0 flame retardant, completely solving the industry problems of traditional flame retardants "contaminating substrates, interfering with electrical performance, and unable to meet electronic grade compliance". It provides a safe and compliant core material solution for high-end electronic manufacturing.

Core strengths

1. Ultra high purity and low impurities, suitable for strict electronic grade requirements

-The ultimate purification process ensures purity: using a combination of "multi-stage recrystallization+precision filtration+vacuum degassing" process, the product purity is ≥ 99.8%, far higher than the industrial grade 99% standard, effectively removing harmful impurities such as chloride ions (≤ 0.001%) and sulfates (≤ 0.002%), avoiding impurity migration that may cause electronic component short circuits or performance degradation.

-Ultra low heavy metal residue: Through ICP-MS detection, the total content of heavy metals such as lead, mercury, cadmium, etc. is ≤ 0.5ppm, far below the RoHS 2.0 limit requirements. There are no residues of phthalates (DEHP/BBP, etc.), fully meeting the "low pollution, high cleanliness" standards for electronic grade materials.

-High phosphorus content empowers efficient flame retardancy: With a phosphorus content of ≥ 42.5%, the flame retardancy efficiency is increased by 40% compared to ordinary aluminum hypophosphite. After compounding with synergists such as MCA and APP, adding 8% to the PCB substrate can achieve V-0 level flame retardancy without affecting the dielectric properties of the substrate.

2. Excellent electrical performance ensures stable operation of electronic devices

-Low dielectric loss and high insulation: dielectric constant (1MHz) ≤ 3.8, dielectric loss factor ≤ 0.005, volume resistivity ≥ 10 ¹⁴Ω· cm. The addition does not significantly change the electrical properties of the substrate, ensuring the signal transmission stability of semiconductor packaging and high-frequency communication equipment.

-Outstanding anti ion migration characteristics: After being placed in a humid and hot environment of 85 ℃/85% RH for 1000 hours, there is no obvious ion migration phenomenon, avoiding electronic components from experiencing "electric migration failure" and meeting the long-term service requirements of new energy batteries, automotive electronics, and other devices.

-Good non corrosiveness and compatibility: The pH value is stable at 3.5-4.5, and it has no corrosive effect on metal contacts and circuit boards. It has excellent compatibility with electronic grade substrates such as epoxy resin, PA, PBT, etc., and does not cause substrate degradation or performance deterioration.

Application scenarios

Semiconductor and electronic packaging field

-Applications: Semiconductor chip packaging materials, electronic component potting adhesives, integrated circuit housings

-As a low dielectric filler to replace some silicon micro powder, the addition amount is 15-30%. While maintaining fluidity, it reduces the dielectric constant by 0.2-0.3 and improves flame retardancy to UL94 V-0. It is used for CPU, GPU, and storage chip packaging.

Printed Circuit Board (PCB) field

-Applications: PCB substrate materials, flame-retardant copper-clad laminates, circuit board casings

-Low loss copper-clad laminate (CCL): composite with high-frequency resins such as PTFE, PPO, cyanate ester, etc., with an E-AHP100 addition of 20-40%, achieving Dk 3.2-3.8 and Df<0.005, meeting the requirements of 5G millimeter wave antenna boards and server high-speed backboards.
