Product introduction
Aluminum hypophosphite ALHP is a new type of inorganic phosphorus flame retardant, the chemical formula is Al (H2PO2) 3. It has the characteristics of slightly soluble in water, not easy to volatilize, and with high phosphorus content, good thermal stability and so on. The application of products with high fire resistance, high thermal stability, and excellent mechanical properties and anti weathering.
Because of its good thermal stability, in the process does not cause the decomposition of the polymer, in the production of plastic film does not affect the composition of volatile conditions in the normal preparation and processing of thermoplastic polymers, the thermal stability of the application of the product has high mechanical properties, has good resistance and weather in the process.


Technical indicators

Aluminum content: (w/w): 12~13
The thermal decomposition temperature (c) (TGA 1% weight loss): more than 290
Low moisture and volatile matter: (w/w): less than 0.5

Product application
ALHP this product is suitable for the flame retardant modification of PBT, PET, PA, TPU and ABS. High flame retardancy has been obtained on the modified plastics such as PA6, PET and so on. When added to PET, the heat generated during combustion will decrease dramatically, and the charcoal content increases after combustion. The flame retardant performance reaches UL94 standard V- 0 level. The experiment proves that the flame retardance effect of other PET flame retardants used in China can be increased by 60%. However, please pay attention to the use of stabilizers, coupling agents and the combination of APP, MC or MCA with other phosphorus and nitrogen flame retardant. For polyester or polyester TPU only 8-12% copies of this product can meet the flame retardant requirements, for SEBS 25 - 35% to meet the flame retardant requirements.


Packing
25kg paper plastic composite bag, lined with plastic bags.
