Adding PE resin in the process of preparing PBT, calcium stearate can improve the processing fluidity of PBT, with the addition of anti-drip agent, a 30% GF reinforced PBT flame retardant material with excellent comprehensive properties such as flame retardant and mechanical properties can be obtained with a small amount of flame retardant added.

The long fiber has large retention length, which makes PP have better rigidity and creep resistance, higher compressive strength, higher flexural strength, better impact property and higher service temperature.

Floating fiber is also known as exposed fiber, that is, glass fiber exposed in the product surface, relatively rough.

At present, LFT-PP (long fiber reinforced PP) has been widely used in automobiles, electric tools, home appliances, water treatment components.
