Low Moisture Aluminum Hypophosphite

Low moisture aluminum hypophosphite CAS No.: 7784-22-7, white ultrafine crystalline powder, with a moisture content strictly controlled below 0.3% and a phosphorus content of over 40%. It has a dual mechanism of condensed phase carbonization and gas-phase flame suppression. When compounded with synergists such as MCA and MHB, it can achieve UL 94 V-0 flame retardant with only 5% -12% addition, completely solving industry problems such as traditional product processing bubbles, surface precipitation, and unstable flame retardant efficiency. It provides compliant and efficient flame retardant solutions for fields such as wire and cable, modified plastics, and potting adhesives.

Core strengths

The breakthrough value of low moisture technology

·Eliminating processing defects: The low moisture characteristic completely avoids bubbles, silver lines, and surface defects during high-temperature processing

·Improving electrical performance: reducing moisture directly improves volume resistivity and dielectric strength

·Extend material lifespan: reduce hydrolysis reactions and enhance long-term stability of polymers

2. Enhanced thermal stability

·Expanded processing temperature window: can maintain stability in high temperature injection molding and extrusion processes at 280-320 ° C

·Synergistic flame retardant effect: When compounded with multiple flame retardants, the low moisture characteristics improve overall thermal stability by 15-20%

3. Excellent dispersibility and compatibility

·Surface modification options: Provide pre-treatment models of coupling agents such as silane and titanate

·Polymer adaptability: exhibiting excellent dispersibility in polar polymers such as PA, PBT, PET, TPU, etc

Application field

Electronic and electrical components

·Connectors and sockets: Adding 20-25% to PA66/PBT alloy to achieve UL94 V-0 (0.8mm)

·Circuit board and housing: maintain high CTI value (≥ 600V), without affecting electrical design safety

·Charging facility components: Tested through 850 ℃ glow wire test (GWT)

High temperature engineering plastics

·Special polyamide: maintains color stability in high-temperature materials such as PA6T/66 and PA10T

·Liquid crystal polymer: as a synergistic flame retardant for LCP, reducing overall formulation costs

·PPS composite material: no decomposition or gas release at processing temperatures of 290-310 ℃

Special applications

·Fiber optic conduit and coating: extremely low precipitation characteristics, ensuring signal transmission stability

·Automotive electronics: significantly improved durability through 85 ° C/85% RH dual 85 testing

·Miniature electronic devices: Fine grained models suitable for thin-walled (0.4-0.6mm) components

Storage suggestions

·Store in a cool and dry place with a relative humidity of less than 60%

·Unopened shelf life: 24 months

·Suggestion after opening: Use as soon as possible or reseal and store

Frequently Asked Questions

Q1: What is the cost difference between low moisture aluminum hypophosphite and conventional products?

A: Although the unit price has slightly increased, the overall benefits are significant: reducing energy consumption in the drying process, lowering waste rates, improving production efficiency, and lowering the total cost of ownership (TCO) by 8-15%.

Q2: How to verify the low moisture characteristics of the product?

A: We provide Karl Fischer moisture test reports for each batch, and customers can also verify them through TGA analysis (weight loss in the 100-150 ° C range).

Q3: Is it applicable to transparent or light colored products?

A: Yes, this product has high whiteness (≥ 94%) and good thermal stability, which will not cause yellowing of the product.

Q4: What is the compatibility with other flame retardants?

A: Compatible well with most polymer additives, it is recommended to conduct small-scale premix testing to obtain the optimal formula.
