PPA is a polysemous word, which means:
Special plastic manufacturers
1. PPA refers to fluoropolymer processing aids:
PPA exists in the polymer matrix in the form of small droplets incompatible with the matrix. PPA has strong affinity and low surface energy with the metal mouth membrane wall, forming a dynamic coating to reduce the flow damping of the melt.
2. PPA means poly (phthalamide):
Under 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:
Special plastic manufacturers
PPA is the English abbreviation of phenylpropanolamine, also known as the stereoisomer of norephedrine. It is a stimulant, decongestant, and the chemical psychotropic drugs of phenethylamine and amphetamine, which are appetite inhibitors.
4. PPA refers to polyphenylenediamine:
Special plastic manufacturers
The thermal deformation temperature of PPA plastic can reach more than 300 ℃, and the continuous use temperature can reach 170 ℃, which can meet your short-term and long-term thermal properties.
