PPA-LGF PPA, full name polyphthalamide, is a semi-aromatic polyamide with no less than 55% terephthalic acid or phthalic acid as raw material, commonly known as aromatic high temperature nylon. PPA has better mechanical properties and high temperature resistance compared to traditional aliphatic nylon (PA6/PA66) materials. PPA materials have relatively low water absorption, good dimensional stability and good corrosion resistance. Glass fiber reinforced PPA composites have high temperature resistance, high strength and low density, and are considered to be the best resin to replace steel with plastic. Compared with traditional short fiber reinforced pellets, long glass fiber reinforced PPA composites have better physical and mechanical properties. Application Because high-temperature nylon can withstand high strength, high loads, and high temperatures in harsh environments, it is ideal for applications in engine areas (such as engine covers, switches, and connectors) as well as transmission systems (such as bearing cages), air systems (such as exhaust control systems), and air intake units. PPA engineering plastic is a high performance engineering plastic reinforced by fiber with high temperature nylon as the base material. The structure and crystalline characteristics of high-temperature nylon make it have more characteristics and excellent overall performance than nylon 66 and nylon 6 and other engineering plastics: strong rigidity, high hardness, high temperature resistance, good chemical resistance and low water absorption, dimensional accuracy and stability and low warpage, excellent fatigue resistance, in many fields including automotive parts, mechanical parts and electrical and electronic parts used in motor parts It is widely used in many fields including automotive parts, mechanical parts and electrical and electronic parts for motor parts, circuit breakers, etc. LGF VS SGF Other materials you may wonder About us Xiamen LFT composite plastic Co., Ltd is a brand-name company that focuses on LFT&LFRT.
