Description
PA66 GF25 Modified Granules Nylon Flame-Retardant Plastic Particles for Nylon Extruding ProfilesProduct Introduction:Polyamides are among the most important and proven technical thermoplastics, known for their heat resistance, stiffness and high mechanical stability.
Polyamides can be classified into different types, with PA 6, PA 6.6 and PA 12 most established on the market. Alongside ABS and PP compounds they are among the most widely used plastics, found across several sectors including the automotive, mechanical engineering, structural and installation engineering, photovoltaics and electrical engineering industries.
Glass fiber is a material consisting of numerous extremely fine fibers of glass.
Glass fibres are used as reinforcement of polymers in various fields such as aerospace, automobile, marine, sporting and leisure goods, and construction and civil engineering. One of the principal advantages of using glass fibres for reinforcement of polymers is their high performance per cost ratio.
Our company use PA 6.6 and glass fiber to produce PA66GF25 granules, which is the most suitable raw material for polyamide thermal break strips production. Advantage:- High mechanical strength
- High toughness
- High softening point
- Good wear resistance
- Self-lubrication
- Long-term work at higher temperatures
- It has high CTI value , excellent electrical insulation, low smoke and low toxicity characteristics.
