Working with Vectra ESD
Is Vectra easy to machine?
Machinable with sharp carbide/PCD tools and high speed, low feed, but the fibrillar skin tends to fuzz and delaminate at edges; avoid deep interrupted cuts and support thin webs.
Can Vectra be welded?
Solvent and ultrasonic welding are unreliable because of the anisotropic skin; use laser transmission welding, heat staking, insert molding or mechanical/adhesive joints (surface pretreatment required for bonding).
Can Vectra be formed, bent or molded?
Inject at 285–330 °C (E-series to ~350 °C) with 40–130 °C molds, small gates and very high injection speed; dry 4 h at 150 °C, place gates to steer flow because weld lines retain only ~20–40 % of flow-direction strength.
What surface finishes work on Vectra?
Molded surfaces reproduce the tool finish well; can be laser-marked, vacuum-metallized or (with LDS grades) laser-activated and electrolessly copper/nickel/gold plated — painting needs plasma or primer pretreatment.

Vectra ESD — frequently asked
What is Vectra ESD used for?
Vectra ESD is typically used for SMT connectors, camera module housings, micro-precision gears and RF/antenna components. In short: industry reference LCP resin; high-flow thin-wall molding; LDS-platable grades available.
What is the tensile strength of Vectra ESD?
Vectra ESD has a typical tensile strength of 150 MPa (21.8 ksi) — stronger than 95% of polymer grades. Strength varies by condition: see the 10 listed tempers.
Is Vectra ESD easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Machinable with sharp carbide/PCD tools and high speed, low feed, but the fibrillar skin tends to fuzz and delaminate at edges; avoid deep interrupted cuts and support thin webs.
Can Vectra ESD be welded?
Not readily — weldability is rated poor (20/100). Solvent and ultrasonic welding are unreliable because of the anisotropic skin; use laser transmission welding, heat staking, insert molding or mechanical/adhesive joints (surface pretreatment required for bonding).
What surface finishes work on Vectra ESD?
Molded surfaces reproduce the tool finish well; can be laser-marked, vacuum-metallized or (with LDS grades) laser-activated and electrolessly copper/nickel/gold plated — painting needs plasma or primer pretreatment.

Inject at 285–330 °C (E-series to ~350 °C) with 40–130 °C molds, small gates and very high injection speed; dry 4 h at 150 °C, place gates to steer flow because weld lines retain only ~20–40 % of flow-direction strength.
What is the maximum service temperature of Vectra ESD?
Vectra ESD is rated for continuous use to about 210°C (410 °F), and briefly to 280°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
