PRODUCT DESCRIPTION

TECHNOMELT PA 646 (e) provides the following product

characteristics:

Application: Molding compound thermoplastic

Typical Applications: Encapsulation

Flammability Rating: UL 94 V0 @ 1.6 to 1.8 mm thickness

Operating Temperature: -40 to +125 ℃

NOURDE 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.
