Product Detail
WADP-10 Ultra-Stable Organic Phosphorus Powder
I. Product Introduction
WADP-10 is a revolutionary halogen-free flame retardant upgrade solution designed to overcome the fatal flaws of traditional ADP in high-temperature applications. Through modified technology, its weight loss rate in a harsh 350 ° C environment drops sharply to ≤ 1.8% (a 89% reduction from the 16% of traditional ADP), and it addresses the issue of yellowing in finished products — after high-temperature baking, it only exhibits controlled slight graying, significantly improving the pass rate for light-colored/transparent products.
WADP-10 is suitable for applications requiring both high thermal resistance and aesthetic appeal, such as new energy vehicle battery components and SMT connectors. It achieves UL94-V0 with an addition rate of approximately 15%, simultaneously optimizing thermal weight loss and electrical safety (CTI ≥ 600V). It provides dual assurance for the safety and aesthetics of engineering plastics in extreme environments.

Revolutionary Breakthrough
89% Lower Weight Loss at 350°C
- Traditional ADP: 16.0% weight loss + blackening
- WADP-10 : 1.8% weight loss + slight graying (no carbonization!)
Color Integrity: Maintains substrate whiteness (vs. conventional ADP-induced darkening)
Critical Applications: EV battery components, SMT connectors, high-flow PA/PBT (>320°C)
IV. Application
- Electrified Mobility: EV charging gun housings, battery tray composites
- High-Temperature Electronics: SMT connectors, 5G antenna modules
- Aesthetic-Sensitive: White PA66 gears, transparent PET films (minimal color impact)
- Synergy Formula: Combines with WADP-10 for V-0 at 18% total loading (PA66/GF30)
V. Use Method
- Mixed with resin, reinforcing material and other modifying additives and then extruded and pelletized by extruder, and the proportion of adding between 10% and 18% can reach V-0 grade (UL94, 0.2~3.2mm).
- Can be used alone or in combination with N-based flame retardants such as MPP and MCA.
- Has high packing density, which can effectively solve the problem of difficult feeding and mixing of PBT, PA, PET and other resins during processing.
V I . Package Storage & Transportation
- Packed in paper and plastic bags, 25kg/bag.
- Storage in cool dry place.
- Transported as non-dangerous chemical goods.
