Fiberglass chopped strands for PP or polyproplene.is cutting from long fiberglass roving which was treated by silane coupling agent and special sizing.This chopped strands has small linear density,good strand integrity and flow ability. so it can not generate wool and ball when mixing with plastic granules,even at mouth of the feeder or side feeder.used for reinforcement of compound to increase mechanical properties(impact,tensile,compressive and flexural),improve dimensional stability and minimize distortion at elevated temperature.Finished products have excellent physical and mechanical properties and surface appearance.
|Filament diameter (μm):||13|
|Fiber length (mm):||4.5±1|
1.good bundle integrity: good integrity to ensure that the chopped strands do not fluff into a ball in long way transportation,to facilitate the feeding process and not clog the feeder of twin screw extruder.
2.good flowability: good flowability and bundle integrity are closely related, which also created favorable conditions for the smooth automatic feeding process.
3.excellent physical and chemical properties: this chopped strands has high tensile strength,elastic modulus,so it can reinforce the polyproplene,and improve its impact,tensile,compressive and flexural properties,improve dimensional stability and minimize distortion at elevated temperature.
The fiberglass chopped strands should be keep dry in their original bags and stored in a suitable place,preferably at room temperature with 35-65% relative humidity.Avoid the sun, rain and fire.
