High Toughness PPS Long Glass Fiber Filling 40% For Industry Use

Product information

PPS is a kind of high molecular material whose main chain is arranged alternately by a benzene ring and sulfur atom. It has good mechanical strength, heat resistance and chemical corrosion resistance, and other comprehensive properties. 

PPS fiber is a few commercial high-performance fibers that can be fused and spun at present. It is the basic material for the core parts of high-temperature and corrosive exhaust bag-type dust removal in thermal power plants and waste incineration plants. It has the characteristics of high filtration accuracy (PM10.0, PM2.5) and long service time (4 years). Toray and Toyo Textile Co., Ltd. have conducted in-depth research and mastered the production technology of high-quality PPS staple fiber, monopolizing the global market of PPS staple fiber and accounting for more than 80% of the global output. 

In recent years, the nanocomposite modification technology has been used in our country to further improve the comprehensive performance of PPS fiber, break the foreign monopoly of high-quality PPS fiber, provide the most cost-effective PPS products for our high-temperature filtration industry, and provide an important guarantee for the industry to enhance the market competitiveness, maintain a domestic leading edge and expand the international market. 

PPS nanocomposite fiber is a new basic material of thermal protective equipment, its development can break the monopoly of foreign materials on special protective equipment, reduce the cost of high-end protective equipment, and improve the popularity of thermal protective equipment in the harsh environment of petrochemical industry, metal smelting, emergency rescue, etc., the market demand is significant. It is of great significance to promote the research and development of personal protective equipment and improve the emergency rescue level.

The difference between PPS-LGF and PPS-SGF

Mechanical properties

The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. When the glass fiber mass fraction is 30%, the tensile strength of PPS/SGF and PPS/LGF composites is 110MPa and 122MPa, respectively. The bending strength was 175MPa and 208MPa, respectively. The flexural elastic moduli were 8GPa and 9GPa, respectively.

The tensile strength, bending strength, and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9%, and 11.3% compared with those of PPS/SGF composites. The length retention rate of PPS/LGF composites is higher. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties.

Thermal performance

When the mass fraction of glass fiber is 30%, the thermal deformation temperature of PPS/SGF and PPS/LGF composites reaches 250℃ and 275℃ respectively. The thermal deformation temperature of PPS/LGF composites is 10% higher than that of PPS/SGF composites. 

The main reason is that the introduction of glass fiber makes the network skeleton of reinforced fiber formed inside the composite material, which greatly improves the heat resistance of the composite material. The size of the glass fiber in PPS/LGF is longer, and the heat resistance improvement advantage is more obvious.

Frequently asked questions

Q: 

Except for the price advantage, what are the advantages of Chinese-made Long-fiber products compared with foreign long-fiber products?

A:

 LFT-G Co., Ltd is a new material enterprise that develops and produces its own brand of LFT long glass fiber and long carbon fiber. It fills the blank of domestic high-end long carbon fiber LFT materials, is more customized, and shortened the production cycle compared with foreign companies. In addition, our company has sales and service offices in Europe/USA/Japan, and domestic Zhejiang/Jiangsu/Guangdong/Chongqing, etc. It can more easily understand customer needs and has more convenient after the sale.

Q:

After Long Glass Fiber is reinforced, glass fiber can enter the surface of the plastic product during the injection molding process, so that the surface of the product becomes rough and floating fiber. How to make the surface of the material smooth?

A:

During the Injection Molding process need to ensure that the plastic particles are well plasticized and dispersed, also ensure that the drying of plastic particles has no moisture removal, mold temperature adjustment to the appropriate temperature, and mold surface is polished in place.
