Engineering plastics                                                                           Polyamide

Chemical structure: PA66:-[NH-(CH₂)₆-NH-CO-(CH₂)₄-CO-]_n-

                                        PA6: -[-NH-(CH₂)₅-CO-]_n-

Property :

■ Good wear resistance 、excellent self-lubricating、good heat  resistance and chemical medicine resistance 、good oil resistance 、high mechanical strength 、good mechanical properties  at low temperature 、good self-extinguishing property 、well  machine shaping .but high water absorption 、high contracted   percentage、not good dimension stability.

■Improve water absorption 、dimension stability 、heat resistance and freeze resistance .be base on the excellent intrinsic property ,it has higher impact strength than pure nylon.

■Good mechanical property 、good electrical property 、good dimension Stability 、good arc resistance 、good dyeing property 、less toxicity property 、good heat resistance 、not yield corrosion gas 、non-volatilization 、non-precipitation and permanent effect of flame retarded.

Typical application:

■Fiber reinforce nylon can be used in pump impeller 、sonveyor chain 、high loaded mechanical parts 、implement handle 、electronic switch 、equipment frame unit 、commodities & hardware unit .flame retarded nylon can be used in electric & electronic socket connector and housing 、automobile interior body connector、upholstery stuff 、commodities interior parts.

Use method :

■ Need to pre-dry before injection molding , dry at 90℃ for 5-6 hours , injection molding condition as follow (only to preference):

Packing & stockpile :

■25 kg plastic valve bag ,storage in dry、well ventilated and keep out of the sun.

Injection molding condition as follow(only to preference)
