Transcription of Welding Conditions for KYNAR PVDF
{{id}} {{{paragraph}}}
Basic Welding Principles In order to produce a high quality weld three perimeters must be controlled, they are: TEMPERATURE----PRESSURE----TIME The temperature must be controlled within the specified range in order to produce the proper melting of the KYNAR pvdf . The pressure in the weld must be properly controlled to avoid forcing the melted KYNAR pvdf out of the weld interface, excessive pressure. Inadequate pressure in the weld interface will not provide adequate mixing of the melt. The time must be controlled to provide uniform heating throughout the weld zone.
