製品概要 & 主な利点
RDP is an oligomeric aryl phosphate with about 10.7% phosphorus. It acts mainly in the condensed phase, promoting char, and it also plasticizes the polymer, improving melt flow. It is used in PC/ABS and PPE/HIPS housings for electronics and office equipment that must meet UL 94 v-0 without halogens.
RDP has a higher phosphorus content than BDP, so lower dosage reaches the same rating; BDP offers better hydrolytic and thermal stability. Acid value and TPP content are the numbers to compare.
Flame retardant and flow aid
Also plasticizes the melt, which helps thin-wall molding.
Specified on your terms
We quote against your phosphorus content, 酸価, TPP content, viscosity and water and send the batch COA for each lot.

包装 & ストレージ
包装
Drums or IBC; tell us which suits your dosing system.
ストレージ
Keep containers closed in a dry store; moisture raises the acid value.
