High-Tg epoxy cure
Gives cured epoxies a high glass-transition temperature and stiffness for composites and laminates.
DDS
4,4'-Diaminodiphenyl Sulfone (DDS) Supplier from China
4,4'-Diaminodiphenyl sulfone (4,4'-DDS) is an aromatic amine used as a curing agent for high-temperature epoxy resins, in the synthesis of polysulfone amide resin and other polymers, and as an intermediate for acid azo and disperse dyes. SUNCHEM supplies DDS in 25 kg drums with a batch COA on every shipment.

製品概要 & 主な利点
4,4'-DDS is an aromatic diamine with a sulfone bridge. Cured with epoxy resins it gives high glass-transition temperature and stiffness, so it is a standard hardener in composite prepregs, adhesives and electrical laminates. It is also a monomer for polysulfone amide (PSA) fiber and other heat-resistant polymers, and an intermediate for acid azo and disperse dyes.
The same molecule is the API dapsone. This page covers industrial grade; pharmaceutical grade is made under GMP and is quoted separately.
Monomer and dye intermediate
A monomer for polysulfone amide fiber and an intermediate for azo and disperse dyes.
