PPA is a polysemous word, which means:

1. PPA refers to fluoropolymer processing aids:

PPA exists in the polymer matrix in the form of small droplets incompatible with the matrix. The results show that PPA has strong affinity and low surface energy with metal mouth membrane wall, forming a dynamic coating to reduce the flow damping of melt.

2. PPA refers to polyphthalamide:

At high temperature and high humidity, the tensile strength of PPA is 20% higher than that of nylon 6, and higher than that of nylon 66; the bending modulus of PPA material is 20% higher than that of nylon, and the hardness is greater, which can resist long-term tensile creep.

3. PPA refers to phenylpropanolamine:

PPA is the abbreviation of phenylpropanolamine, also known as the stereoisomer of norephedrine. It is a stimulant, decongestant, and appetite inhibitor of phenylethylamine and amphetamine chemical psychotropic drugs.

4. PPA refers to poly (p-phenylenediamine)

The thermal deformation temperature of PPA plastic is as high as 300 ℃, and the continuous use temperature can reach 170 ℃. It can meet the short-term and long-term thermal properties you need.
