LFT-G PPA Long Glass fiber higher toughness reinforced plastic polymer for machanical parts 12mm original color

What is PPA plastic?

ppa is polyphthalamide resin, a semi-aromatic polyamide made from terephthalic or phthalic acid. Polyphthalamide (PPA for short) is a semi-crystalline thermoplastic aromatic polyamide, commonly known as aromatic high temperature nylon, with a long-term working temperature of up to 180 degrees. PPA materials have excellent overall physical properties, good performance in thermal, electrical, physical and chemical resistance, especially in high temperature still have high strength and excellent dimensional stability.

What is the 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 fibers 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.

From the length classification, we can divide into continuous glass fiber, short glass fiber and long glass fiber (LGF). Compared with short glass fiber, the long glass fiebr has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher toughness than short glass fiber, and the tensile strength is increased by 0.5-1 times.

Q & A

Q. The product is easy to brittle, so changing to use long fiber reinforced thermoplastic materials can solve this problem?

A. The overall mechanical properties must be improved. The chatacteristics of long glass fiber and long carbon fiber are the advantages in mechanical properties. It has 1-3 times higher toughness than short fiber, and the tensile strength is increased by 0.5-1 times.

Q. What are the main features and advantages of long fiber reinforced thermoplastics?

A. Compared with traditional short fiber materials, the main features of LFT-G thermoplastic long glass fiber and long carbon fiber are machanical properties, high impact and tensile modulus, which are more suitable for some large products or structural load-bearing parts. It can do injection molding, extrusion of sheets, profile pipes, etc. and it is simple processing.

Q. Under what circumstances can long fiber replace short fiber? What are the common alternative materials?

A. Traditional staple fiber materials can be replaced with long glass fiber and long carbon fiber LFT materials in the case of customers whose mechanical properties cannot be met or where higher metal substitutes are desired. For example, PP long glass fiber is often replacing nylon reinforced glass fiber, and nylon long glass fiber is replacing PPS series.
