APP
PUERCHEM
Ammonium Polyphosphate
APP
CAS: 68333-79-9
Molecular Formula: (NH4PO3)n
Application：It can be used in textile coating, intumescent fireproof coatings and thermoset resins, such as polyurethane, UP resin and epoxy resin. It can also be used in the retardant of fiber, wood, rubber and plastic products. Due to its high molecular weight(n>1000) and good heat stability, APP can be used as main ingredient of expanding retardant thermoplastic.,especially used in the PP achieving UL94-V0 for electronic unit.

AP740 | 27.0-28.0 | 17.0-18.0 | ≤0.20% | 6.0-7.0 | ≈15μm |
Packing and storage:25 kg /bag, using kraft bags with PE inner. Handle with care, keep airtight and dry.
Q1: Are you a manufacturer?
A: Yes, We are the manufacturer involved in this line for about 20 years.
Q2: Do you have stock?
A: We understand most customers prefer stock, so we'll try to keep stock for most products. However, for some rare products, we won't keep stock and it needs time to synthesize.
Q3: Do you provide free sample?
Yes, we can provide free sample if we have in stock.
Q4: What's the delivery time?
If in stock for 3-7days. if not, 5-15 days also according to your quantity after advanced payment.
PUER collaborates with university and institutes to develop green eco-friendly flame retardants. We are committed to providing high performance halogen free flame retardants to help our customers to realize successes via sustainable solution. We take innovation and sustainable development as our mission. PUER will always supply customized products for global customers’ needs. We always offer best products and excellent service.
PUER will provide high-quality products and competitive price for you.
Intumescent Flame Retardant System: APP/MPP/PER Synergy
Ammonium Polyphosphate (APP) Acts as the acid source.
Melamine Polyphosphate (MPP) OR (MELAMINE) as a co-acid source and gas-generating agent.
Pentaerythritol (PER) Functions as the carbonizing agent.
If you have required of samples to test , Please don't hesitate to contact with me!
