LFT-G PPS Polyphenylene sulfide conpounds long glass fiber pellets original color for home appliance

Polyamide 12 filling long glass fiber

The recommended long-term working temperature of polyphenylene sulfide resin (PPS) is 220~240℃. The material has good thermal stability, and its mechanical properties remain at about 80% and 60% of their original values at 100°C, 160°C and 200°C, respectively. The material has excellent creep resistance and fatigue resistance at room temperature.

The material also has excellent resistance to acids, alkalis, salts, organic solvents and other media, except for oxidizing acids and strong oxidizing media, and is almost insoluble in any chemical solvent below 170°C. It is especially suitable for hydrofluoric acid, halogenated hydrocarbons and chloride ion corrosion resistance.

PPS is a flame retardant material with an oxygen index of 46 to 53, better than most engineering plastics. Polyphenylene sulfide has high resistance and low dielectric constant electrical properties, and can maintain good electrical properties under high temperature and high humidity conditions.

In addition, the mechanical properties of the resin material are not very outstanding because it has good affinity with glass fiber, carbon fiber, inorganic filler and solid lubricant, and the modification is good, so the particles used in injection molding are mainly modified and reinforced by various fibers and inorganic fillers.

LGF & SGF

Nylon particles of ordinary glass fiber:

Size size is about 3-4mm, length to width ratio 50-250

Long glass fiber nylon particles:

Size is about 10-12mm, aspect ratio >400

In addition, the distribution of glass fiber in the two kinds of particles is also different.

Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved.

Compared with SGF, LGF has improved rigidity, strength and modulus, especially the notched impact performance has been greatly improved.

The rigidity retention rate of long glass fiber is better than that of short glass fiber, and long glass fiber is more resistant to heat aging.

The creep performance is affected by time, temperature and load. At 120℃ and 40Mpa load, the creep of long glass fiber is significantly better than short glass fiber. This is critical for parts with long term static pressure, and long glass fiber can be tried when short glass fiber cannot meet the requirements.

Shrinkage is crucial to the size of the part. The transverse shrinkage of short glass fiber material is much higher than the longitudinal shrinkage, and the anisotropy is more serious, resulting in difficult to control the size of the part and obvious shrinkage. In contrast, the transverse and longitudinal shrinkage rates of long glass fiber materials are very close, showing isotropy, improving the risk of part warpage and making the dimensions more controllable.
