The characteristics and functions of PPA plastics

The characteristics and functions of PPA plastics

2023-05-30

The scientific name of PPA plastic is polyphthalamide. This plastic has advantages in strength, toughness, hardness, fatigue resistance and creep resistance. In the continuous high temperature and high humidity state, it can also withstand the high temperature of 200 ° C, and continue to maintain its good dimensional stability, which can eliminate shark skin. In general, in tensile strength, PPA is 20% higher than nylon 6 and higher than nylon 66; In the bending modulus, PPA plastic is 20% higher than nylon, so the hardness is greater, and the tensile and creep equipment is long. PPA is stronger than PA in P's resistance to gasoline, grease and coolant. PPA also improves surface finish.

First, injection mold 1. If the mold cavity is poorly processed, such as scars, microholes, wear, roughness and other deficiencies, it is bound to react to the plastic parts, making the plastic parts poor luster, in this regard, it is necessary to carefully process the mold, so that the surface of the cavity has a small roughness, if necessary, polishing chromium plating.

PEEK (polyether ether ketone) resin is a special engineering plastic with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing. It is recognized as the thermoplastic material with the highest comprehensive performance for harsh environments. The following POM plastic manufacturer small series for you to introduce:

PES plastic features

PES plastic features

2023-05-30

PES plastic is made of 4,4 '-disulfonyl chloride diphenyl ether in the catalysis of anhydrous ferric chloride, and diphenyl ether condensation, English simply called PES plastic. Refractive index 1.85, glass transition temperature 225℃, thermal deformation temperature 203℃ (1.82MPa). The heat resistance is between polysulfone and polyaromatic sulfone, and the long-term use temperature is 180-200 ℃. Excellent aging resistance, up to 20 years at 180 ℃. Good fire resistance. Even if it burns, it doesn't smoke. The creep resistance is good, and the strain change under 150 ℃ and 20MPa pressure is only 2.55%. The following PPA plastic manufacturer Xiaobian for you to introduce:
