LFT-G PPS sulfure de polyphénylène LGF fibre de verre composite longue fibre de verre personnalisée plastiques techniques

What is the PPS?

Polyphenylene sulfide (PPS) is a new thermoplastic resin with high performance. By filling, modified with excellent high temperature resistance, corrosion resistance, wear resistance, flame retardant, balanced physical and mechanical properties and excellent dimensional stability and excellent electrical properties and other characteristics of the new high performance thermoplastic resin, as well as high mechanical strength, chemical resistance, flame resistance, good thermal stability, excellent electrical properties and other advantages.

It has the advantages of hard and brittle, high crystallinity, inflammability, good thermal stability, high mechanical strength, excellent electrical properties, strong chemical corrosion resistance and so on. The mechanical properties of pure PPS are not high, especially the impact strength is relatively low.

Good creep resistance under load, high hardness; High wear resistance, the wear at 1000 RPM is only 0.04g, and will be further improved after filling F4 and molybdenum disulfide; It also has a certain degree of self-moistening. The mechanical properties of PPS are less sensitive to temperature.

What is the PPS-LGF?

PPS is one of the best varieties of heat resistance in the engineering plastic department. The thermal deformation temperature of the material modified by glass fiber is generally greater than 260 degrees, and the chemical resistance is second only to PTFE.

In addition, it also has small shrinkage, low water absorption, good fire resistance. Good resistance to vibration fatigue, strong resistance to arc, especially at high temperature. Excellent electrical insulation in high humidity.

But its disadvantages are brittleness, toughness, low impact strength, after modification, can overcome the above shortcomings, obtain very excellent comprehensive performance.

As a plastic, its properties and uses far exceed those of ordinary plastics, and in many ways it is as good as metal materials.

Excellent material PPS has the advantages of high temperature corrosion resistance, excellent mechanical properties, can replace metal including stainless steel, copper, aluminum, alloy, etc., is considered to be the best substitute for metal, copper.

What is the application of PPS-LGF?

PPS is now widely used in automotive, aerospace, household appliances, mechanical construction and chemical industry for a variety of structural parts, transmission parts, insulation parts, corrosion resistant parts and seals. Under the condition of ensuring sufficient strength and other properties, the weight of the product is greatly reduced.
