    Amostra de compostos de fibra de vidro longo de enchimento PPS modificado de alto desempenho LFT disponível branco natural 12 mm
    Polyphenylene sulfide PPS is one of the typical representatives of special engineering plastics, with a linear structure of alternating benzene rings and sulfur atoms. In the condensed structure, PPS is easy to crystallize, crystallinity of nearly 70%, therefore, has good thermal stability, chemical stability and dimensional stability, etc. PPS mainly has the following five performance advantages. (1) excellent heat resistance. pps melting point of more than 280 ℃, heat deflection temperature of more than 260 ℃, and after high-temperature heat aging treatment, the strength retention rate is high. (2) since the flame retardant. PPS itself has flame retardant, without adding flame retardants flame retardant level can reach UL94 V- 0 level. (3) good mechanical properties. PPS is a brittle material, has good creep resistance, high surface hardness, good wear resistance, and carbon fiber and other materials compound, but also shows good self-lubricating properties. (4) excellent chemical resistance, irradiation resistance. pps below 200 ℃ almost insoluble in any solvent, can withstand almost all inorganic substances, radiation dose up to 108Gy. (5) good processing properties. pps melt viscosity is low, as the resin matrix of composite materials, for the reinforcement of the flow of excellent wetting effect. As PPS has the above performance advantages, and compared to other high-performance thermoplastic resins and easy processing, low cost, so become an excellent resin matrix for the manufacture of composite materials. Long glass fiber Glass fiber is an inorganic non-metallic material with excellent performance, is a natural mineral with silica as the main raw material, add specific metal oxide mineral raw materials, mixed evenly, molten at high temperature, molten glass liquid flow through the funnel outflow, in the role of high-speed pull gravitational force is drawn and rapidly cooled and cured into a very fine continuous fiber. Glass fiber monofilament diameter from a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber original filament are composed of hundreds or even thousands of monofilaments. Glass fiber basic properties: The appearance of a smooth cylindrical surface, the cross-section is a complete circle, round cross-section to withstand the load capacity; gas and liquid through the resistance is small, but the surface is smooth so that the holding force of the fiber is small, not conducive to the combination with the resin; density is generally in 2.50-2.70 g/cm3, depending mainly on the glass composition; tensile strength than other natural fibers, synthetic fibers to be high; brittle materials, the elongation at break is very small ; water resistance and acid resistance is good, while alkali resistance is poor. It can be divided into continuous glass fiber, short glass fiber (SGF) and long glass fiber (LGF) by length classification. Long glass fiber is the most widely used glass fiber at present. And Xiamen LFT plastic composite company is focuses on the produce of long glass fiber compounds for many years. SGF VS LGF 1. The difference in size length Engineering materials long glass fiber and short glass fiber, literally means the difference in size length; more common short glass fiber size is about 0.2mm-0.6mm between; long glass fiber size is about 6mm-25mm between. 2. Performance strength differences Different lengths of glass fibers are different in their performance strength, the fiber length of long glass fibers in the composite material inside the impact strength than short glass fibers stronger. 3. Production process is different Produção de fibra de vidro longa, altos requisitos de matérias-primas, especialmente o processo de fabricação requer que a superfície da fibra de vidro seja ativada, o processamento não pode ser inundado com fibras de vidro, bem como ocorre o fenômeno de vazamento externo. Produção de fibra de vidro curta, porque o tamanho geralmente não tem requisitos especiais, portanto a produção é relativamente fácil, os requisitos de matérias-primas não são tão altos, os custos de produção para os fabricantes são baixos. 4. Diferentes métodos de produção e processamento Os métodos de produção e processamento de fibras de vidro longas geralmente usam moldagem por injeção e moldagem; enquanto a maioria dos métodos de moldagem por injeção de fibra de vidro curta. Processo do produto TDS apenas para referência Detalhes Número Cor Comprimento Amostra Embalagem MOQ Porto de Carregamento Prazo de entrega PPS-NA-LGF40 Cor original (ou como você exigiu ) 12mm (ou como você exigiu) Disponível 25kg/saco 25kg Porto de Xiamen 7 a 15 dias após o envio Porque escolher-nos 1.
