　　technomelt pa 646

　　product deion

　　technomelt pa 646 (e) provides the following product

　　characteristics:

　　technology: polyamide

　　appearance: black

　　product benefits:

　　● easy moldability

　　● good adhesion to a variety of substrates

　　● excellent moisture resistance

　　● excellent environmental resistance

　　● simplified process flow

　　application: molding compound thermoplastic

　　typical applications: encapsulation

　　flammability rating: ul 94 v0 @ 1.6 to 1.8 mm thickness

　　operating temperature: -40 to +125 ℃

　　technomelt pa 646 (e) high performance thermoplastic polyamide

　　is designed to meet low pressure molding process requirements. this

　　product can be processed at low processing pressure due to its low

　　viscosity, allowing encapsulation of fragile components without

　　damage. this material produces no toxic fumes in process and

　　provides a good balance of low and high temperature performance.

　　technomelt pa 646 (e) is particularly suited to applications such as

　　computer connectors and memory sticks where high strength and

　　hardness are desired.

　　liquid-state typical properties

　　viscosity: @ 225 ℃, mpa.s (cp) 4,500

　　specific gravity @ 25 ℃: 0.98

　　softening point, ℃ 170 to 180

　　molding temperature, ℃ : 200 to 240

　　technomelt pa 646 (e) has been formulated to provide the best

　　possible moldability and as wide a molding latitude as possible. much

　　of the final molding parameters will be determined by the mold design.

　　although molding and curing conditions will vary from situation to

　　situation, recommended starting ranges are shown above.
